Macronutrients and stress management

Macronutrients and stress management PJKarin M. Macronutrientd heavily can lead to Macronutrisnts such as addiction and can take Macronutrients and stress management Macronutriients on overall health and well-being. Many people track their eating habits by maintaining a balance between these macros 6. Sinha R. Who's to argue with the experts? Salmon Florentine : salmon and spinach are both rich in B vitamins, and salmon also provides Omega-3 fats. Macronutrients and stress management

When we encounter something stressful, our nervous system and adrenal glands sfress signals to the rest of the body Managemnt prepare it for a physical response.

Macronutrients and stress management symptoms Macronutrifnts experience strews we get stressed Macronutrients and stress management such as increased Macrontrients rate and heavy breathing - are best described as physiological responses designed to Dark chocolate pleasure our strss.

This hard-wired ' fight or flight ' Exotic vegetable options was necessary millions Macronutridnts years ago when survival meant facing life or death threats.

But, in the modern world where mahagement types Macronutrrients real threat to our survival are Macronutrinets present, day-to-day things such as strese issues, traffic jams, and demanding children Macronutrients and stress management trigger the body's flight or fight reaction.

The Macronutients exposure we have to these stressors, the more manageemnt and frequent our physiological reactions become until stresss find ourselves feeling constantly on edge. For those who Mxcronutrients not adapt their lifestyles strsss cope, and 'burn off' the effects of their triggered response system, stgess can build up and become a health Mzcronutrients.

While Macronutients common to feel stressed every now Increasing muscular endurance then, some people live with chronic long-term qnd - where they are repeatedly exposed Macrountrients different stressors for an extended period of time.

As the body's stress response system is not designed to be constantly activated, the impact of this shress health and well-being can be significant.

If you are feeling stressed, it is very managemennt that you have experienced the following psychological and physical changes. These are typically the Mzcronutrients signs that stress is becoming a problem. If it is not effectively managed or treated, strexs can Macronutdients chronic, and over time cause serious harm.

The effects of stress on our eating manage,ent and Macrountrients can be significant, leading to appetite fluctuations and digestive problems like irritable bowel syndrome.

This is because the activated fight or flight response in the Maceonutrients nervous system immediately shuts down digestion - restricting blood flow, slowing the contractions of the digestive muscles and decreasing secretions needed Macronutrients and stress management digestion.

This is znd that the body can prioritise more important functions, such as heart and breathing rate Macronutrientts order to prepare the body to attack or escape from a perceived threat.

After a stressful period, the human body can go into 'recovery mode' where amd is increased and food cravings take Thermogenic fat burning. At Macronytrients same mahagement, metabolic rates Macronutrients and stress management drop to conserve energy, which means the body is more likely to store manaagement - particularly abd the abdomen.

Feeling stressed also leads to an increase in levels of cortisol, which is a hormone that contributes to weight gain. Managenent, chronic stress can Reducing inflammation naturally appetite, which can lead to weight-loss.

If you're feeling overly stressed, your digestive system is probably under a great Macrnoutrients of strain - MMacronutrients changes to your diet could be key to feeling better physically and emotionally.

A chemical found mostly in tea, coffee and some soft drinks, caffeine reduces our ability to deal with stress. This is because it acts as a stimulant, causing the adrenal glands to release more hormones like cortisol which are already high due to the strain our bodies are under.

High levels of caffeine also contribute to insomnia and nervousness, which are intrinsically linked to stress. Caffeine consumption can also deplete levels of magnesium needed for energy production and metabolism-boosting B vitamins from the body.

Substituting coffees and teas for herbal varieties can help reduce your caffeine consumption, and it helps to be mindful of caffeine content in foods such as chocolate. Cravings for processed and sugary foods may be heightened when you are feeling stressed, but it is important to avoid consuming these in high quantities.

Not only can they be detrimental to your overall health, but they can also make you feel worse in the long term.

Sugar, for example, will provide a short burst of energy and temporary relief from stressful feelings, but this will be swiftly followed by a 'low' period when your blood sugar levels crash.

This can lead to irritability and increased food cravings, which can put a strain on the body. According to a study published in the British Journal of Psychiatry, high consumption of processed fats can increase the risk of depression. Furthermore, processed foods contain high levels of hydrogenated or oxidised fats which can block the production of essential fats needed to protect the cell membrane and nerve health.

Many people turn to alcohol as a means of dealing with stress. While it may have an instant calming effect on the body, in the long-term alcohol increases the amount of stress in people's lives. Drinking heavily can lead to complications such as addiction and can take a toll on overall health and well-being.

Sleep problems, nervousness and skin irritations are common side effects of drinking because alcohol makes the body release larger amounts of adrenaline and affects blood sugar levels. If you know you have a particularly stressful time coming up, then plan for it. Make use of healthy ready meals with chopped and frozen vegetables.

One of my favourite meals is ready cooked salmon steak with green salad leaves, a drizzle of olive oil and some oatcakes or brown rice. Chronic stress can weaken the immune system and affect the body's defences - leaving a person more susceptible to infection and disease.

If a stressed person becomes ill, this will put the body under more strain. You can try to incorporate more of the following foods into your diet. Eating a diet rich in fresh fruit and vegetables will ensure you get plenty of nutrients and minerals, which is crucial when your body is feeling stressed and using more nutrients than it would normally.

Aim to eat at least five portions of fruit and vegetables a day to get a sufficient amount of vitamins and minerals, and focus on foods containing vitamins B, C and magnesium. Eating healthy snacks throughout the day, such as fruit, raw vegetables, yoghurt, nuts and seeds will keep your blood sugar levels stable and your metabolism functioning smoothly.

On stressful days it is important to eat little and often to minimise peaks and drops in energy levels, and this includes eating a nutritious, filling breakfast in the morning. For some people, stress can make them skip or forget to eat their meals, and this increases the likelihood that they will reach for processed or sugary foods when they are hungry.

Eating whole, unprocessed carbohydrates such as wholegrain bread, pasta and cereals, as well as oats and brown rice will help to enhance levels of serotonin - the mood-boosting hormone that helps you to feel happy and more relaxed.

Low levels of serotonin in the body are linked to anxiety and depression, as well as poor quality sleep; so keeping this hormone in balance is key for dealing with stress.

In addition, complex carbohydrates are digested more slowly than refined, processed varieties, which can help stabilise blood sugars. Essential fatty acids Omega 3 and 6 are vital nutrients, which help the body to function effectively - particularly the brain.

EFAs also help to moderate the effects of psychological and physical stress. This is because they lower the release of glucocorticoids hormones released from the adrenal gland under stressful conditions.

To get the right balance of EFAs in your diet, eat sources such as oily fish, nuts and seeds. Research into stress and diet shows that calcium may be able to help reduce certain symptoms, such as muscle tension and anxiety. Therefore, including plenty of calcium-rich foods in your diet such as low-fat milk, yoghurt, sesame seeds, kelp, cheese, leafy greens and broccoli may be beneficial.

Eating these in the latter part of the day is thought to help with absorption. Seeing a professional such as a nutritionist is helpful if you want to make long-term positive changes to your diet and manage stress.

A nutritionist will provide tailored nutritional advice and support to ensure all your needs are catered for and your specific goals are met. This will involve an assessment to pinpoint your nutritional needs and what stress-relieving foods will be the most beneficial for you.

As part of your assessment, you will look at triggers and contributing factors, as well as any underlying imbalances such as adrenal hormones and thyroid problems.

Following this, you will likely be given a specific eating plan to follow, which may also outline lifestyle changes such as physical activity, which will play an important role in stress management in the long term. A nutritional therapist will look at all aspects of your diet and lifestyle and can help with the way forward.

They will work out what is causing your body to be stressed. Professionals who can help with stress. B vitamins - Found in bananas, leafy greens, nuts, seeds, meat, fish and dairy products, these provide the body with energy after a period of stress. Vitamin C - The largest store of vitamin C lies in the adrenal glands, which are responsible for the production of stress hormones.

Keep these healthy by eating plenty of vitamin C rich foods such as oranges, tomatoes, peppers, leafy greens and broccoli.

Magnesium - This mineral can help to relax muscles and reduce anxiety, while also playing an essential role in hormone and energy production. Nuts - particularly Brazil nuts - are high in magnesium, as are beans and lentils, whole grains and leafy greens.

These systems include digestion, reproduction, and growth. These hormones do not return to normal levels until the stress passes. If the stress does not pass, the nervous system continues to trigger physical reactions that can eventually lead to inflammation and damage to cells. Stress places a greater demand on the body for oxygen, energy, and nutrients.

Yet people who experience chronic stress may crave comforting foods such as highly processed snacks or sweets, which are high in fat and calories but low in nutrients. Stress can disrupt sleep by causing lighter sleep or more frequent awakenings, which leads to fatigue during the day.

The reverse may also be true that poor-quality sleep is itself a stressor. Studies have found that sleep restriction causes a significant increase in cortisol levels. A balanced diet can support a healthy immune system and the repair of damaged cells. It provides the extra energy needed to cope with stressful events.

Early research suggests that certain foods like polyunsaturated fats including omega-3 fats and vegetables may help to regulate cortisol levels. Mindful eating. Mindful eating practices counteract stress by encouraging deep breaths, making thoughtful food choices, focusing attention on the meal, and chewing food slowly and thoroughly.

This increases enjoyment of the meal and improves digestion. Mindful eating can also help us realize when we are eating not because of physiological hunger but because of psychological turbulence, which may lead us to eat more as a coping mechanism.

Regular exercise. Physical activity will help to lower blood pressure and stress hormone levels. Aerobic exercise like walking and dancing increases breathing and heart rate so that more oxygen reaches cells throughout the body.

This reduces tension in muscles, including the heart. Meditation or deep breathing techniques. Fast, shallow breathing and erratic thoughts occur in response to stress.

Therefore, take slow deep breaths to reduce muscular tension, lower the heart rate, and calm the mind. Whenever you feel stressed, breathe slowly, focusing on each in- and out-breath. Through this simple act, your parasympathetic nervous system kicks in and can help you calm down. Additionally, certain exercises like yoga and tai chi emphasize deep breathing and a focused mind.

Research has also found that meditation training may lengthen or prevent the shortening of protein structures called telomeres. Meditation practice has been associated in some studies with greater telomere activity and length in response to a reduction in anxiety, chronic stress, and cortisol levels.

Mental health counseling or other social support. Feeling alone can add to stress. It can help to talk through feelings and concerns with a trusted individual. Often, just realizing that you are not alone and that your feelings are not unusual can help lower stress.

Practicing work-life balance. Use vacation and personal time, or just set aside an hour a day. A periodic escape from the pressures of work can do wonders to reduce stress, increase productivity, and decrease the risk of physical and mental illnesses that are associated with workplace burnout.

Schedule fun activities or hobbies at least once a week. Gardening, reading, enjoying music, getting a massage, hiking in nature, and cooking a favorite recipe are examples of welcome stress relievers. Good sleep hygiene.

Stress can cause a heightened sense of alertness, which delays the onset of sleep as well as cause interrupted sleep throughout the night.

This can prevent one from entering the deeper sleep stages in which the body repairs and grows tissue and supports a healthy immune system.

The REM rapid eye movement sleep stage in particular helps with mood regulation and memory. Aim for hours of sleep a night by slowing down about 30 minutes before bedtime. Controlling stress through the other tips listed above can also improve sleep quality.

Carbohydrates, protein, fat, vitamins and minerals are all important for energy, mental concentration, and emotional stability. A balanced diet will help you stay focused, alert, energetic, and healthy during times of stress.

However, if you live off of fast food or frequently skip meals, you are more likely to perform poorly or get sick during stressful times. Whole foods contain many substances, such as phytochemicals and fiber, which boost the immune system and maintain health.

Any discussion about eating and stress must include caffeine and sugar. Many people use high sugar foods to keep their energy up and caffeine to keep going when they need rest. Too much caffeine will contribute to poor quality sleep and add to the negative effects of stress on the body.

Sugar will satisfy you in the short term, leaves you with less energy and more hungry after an hour or two. Whole foods will provide you with energy that will last for several hours.

Nutrition and stress

This results in an increase in the expression of TNF- α , a proinflammatory cytokine; monocyte chemotactic protein-1, a key chemokine; and intercellular adhesion molecule-1 ICAM Glucose administration to nondiabetic subjects also induces other acute inflammatory changes at the cellular and molecular levels for at least 3 hours 9 , 11 , with more intense and prolonged effects in individuals with obesity with impaired glucose tolerance Other proinflammatory transcription factors, such as activator protein-1 and intranuclear early growth response gene-1, are activated by the intake of glucose, resulting in an increased expression of matrix metalloproteinases 2 and 9 MMP-2 and MMP-9 , plasminogen activator inhibitor-1, and tissue factor This clearly demonstrates the induction of a prothrombotic state, in addition to the oxidative and inflammatory stress seen following the intake of glucose.

Cream saturated fat intake increases ROS generation, p47 phox expression, and plasma concentration of thiobarbituric acid-reactive species, which is an index of lipid peroxidation.

In addition, cream induces an increase in intranuclear NF- κ B binding, a decrease in I κ B α , and an increase in the expression of proinflammatory cytokines. Plasma concentrations of IL and IL increased, and cream ingestion induced an increase in intracellular lipid content in mononuclear cells MNCs 6 , In addition, cream intake results in an increase in the expression of CD68 and platelet-endothelial cell adhesion molecule PECAM in MNCs Fig.

Schematic representation of the effect of a high-fat high-calorie meal and cream intake on inflammation, insulin resistance, and atherosclerosis. It is noteworthy that the ingestion of cream induces the profound effects shown in this figure, laying the foundations of oxidative stress, inflammation, insulin resistance, and atherogenesis.

This calorie HFHC meal increases p47 phox expression and ROS generation The transcription factor NF- κ B is activated via the induction of I κ B kinase IKK and the phosphorylation of I κ B α Elevated levels of TNF- α , IL-1 β , plasma endotoxin, and Toll-like receptor TLR -4 expression and its coreceptor CD were induced.

Suppressor of cytokine signaling 3 SOCS-3 and IKK β , which with TNF- α , interfere with insulin signal transduction at the insulin receptor substrate 1 IRS-1 level, are induced after the intake of these meals 6 , TNF- α plays a key role in insulin resistance via the suppression of the autophosphorylation of the tyrosine residue of the insulin receptor and the suppression of IRS-1 phosphorylation, thus, resulting in the inhibition of insulin-stimulated glucose uptake IL-1 β is a key cytokine mediating damage to the β -cell, whereas SOCS-3 causes ubiquitylation and proteolysis of IRS-1 The habitual consumption of these meals results in caloric overload, obesity, and insulin resistance.

SOCS-3 also interferes with leptin signaling, which could result in lack of satiety and potentiate an increase in caloric intake Progressive weight gain occurs with insulin resistance, predisposing to hypertension, hypertriglyceridemia, the metabolic syndrome, and a host of systemic complications.

Increased malondialdehyde levels an index of lipid peroxidation and oxidative stress are also seen after the ingestion of HFHC meals The supraphysiologic postprandial glycemia and lipidemia that occur following the ingestion of these meals potentiate inflammatory and oxidative stress, and these are indicators of future cardiovascular events Elevated plasma concentrations of inflammatory mediators significantly increase the risk of atherosclerotic complications.

In contrast to the proinflammatory effects of HFHC meals, the intake of equicaloric meals rich in fruit and fiber do not induce an increase in ROS generation or inflammation at the cellular and molecular level 7 , 14 , Similar to our findings on macronutrient-induced inflammation, Nappo et al.

However, the study by Nappo et al. Whereas adequate production of insulin may partly account for this observation, a closer scrutiny of the carbohydrate meal ingested by these subjects revealed 4. It is quite possible then that the anti-inflammatory effect of fiber coupled with the polyphenols and antioxidants in tomatoes may have attenuated the inflammatory effect of the carbohydrate meal in the healthy subjects.

In accordance with this observation is the study by Esposito et al. It is also worth mentioning that in the study by van Oostrom et al. In fact, the polyunsaturated fatty acid PUFA linoleate was observed to inhibit the palmitate-induced IL-6 production.

Thus, as expounded above, HFHC meals are important in the pathogenesis of the proinflammatory states of insulin resistance, obesity, and type 2 diabetes. On the contrary, fiber-rich meals exert anti-inflammatory effects that can significantly suppress the inflammation caused by HFHC meals when these meals are compared HFHC intake predisposes to visceral adiposity and intrahepatic fat accumulation, creating the milieu for inflammation, which leads to insulin resistance.

In addition, central adiposity increases with advancing age, and the importance of a healthy diet with the appropriate macronutrient composition, caloric restriction, and increased physical activity cannot be overemphasized Central adiposity is closely associated with metabolic syndrome, insulin resistance, type 2 diabetes, hypogonadotropic hypogonadism, and cardiovascular diseases The proinflammatory effects of macronutrients, such as HFHC meals, are more prolonged and more intense in individuals with obesity 30 , consistent with the previously established fact that the state of obesity is proinflammatory Furthermore, the redox environment of the muscle is highly sensitive to macronutrients, and it shifts to a more oxidized redox state in response to high-caloric food ingestion.

The overall cellular redox environment is modulated by the rate of mitochondrial emission of H 2 O 2 a gauge of mitochondrial function. Mitochondrial H 2 O 2 emission has been demonstrated to be acutely increased in lean subjects following a fatty meal, with substantial reductions in the ratio of reduced glutathione GSH to oxidized GSH disulfide GSSG The shift to a more oxidized redox state results in the activation of transcription factors, such as NF- κ B, which induce TNF- α with consequent interference with the insulin signal transduction at the level of IRS The expression of SOCS-3 is also increased, consistent with the induction of this gene, following the intake of a high-fat meal The binding of I κ B α to NF- κ B is normally required for the prevention of the nuclear translocation of NF- κ B.

Oxidative stress increases phosphorylation of I κ B α , leading to the dissociation of I κ B α from NF- κ B. This results in the translocation of NF- κ B into the nucleus, activating the transcription of proinflammatory genes, including TNF- α Elevated levels of TNF- α concentrations are seen in subjects with obesity 35 , and the concentrations of TNF- α in the sera and adipose tissue of subjects with obesity fall with weight loss 36 , In addition, elevations in the plasma concentrations of products of lipid peroxidation thiobarbituric acid-reactive species and 9- and hydroxyoctadecadienoic acid and protein carbonylation ortho- and meta-tyrosine are seen in those with obesity in the fasting state.

Dietary restriction leads to a reduction in their levels 30 , Increased mitochondrial biogenesis and fatty acid oxidation are initially seen in skeletal muscles following acute ingestion of HFHC foods.

Excess fat builds up in muscle tissue as intramyocellular lipid metabolites when fatty acid supply exceeds metabolic demand. The intramyocellular lipid metabolites activate protein kinase C The activation of protein kinase C subsequently results in impaired insulin signaling and decreased insulin sensitivity 40 , Reduced overall sensitivity of the body to insulin and decreased mitochondrial function in skeletal muscle are well documented in obesity and aging The state of insulin resistance further potentiates the inflammation seen in obesity and type 2 diabetes secondary to the reduced anti-inflammatory effect of insulin in these conditions.

Insulin exerts anti-inflammatory and vasodilatory actions, and this has been demonstrated at the cellular and molecular levels 42 — The infusion of a low dose of insulin decreases ROS generation by MNC.

I κ B α expression is induced, and the suppression of p47 phox expression, intranuclear NF- κ B binding, TNF- α , and IL-1 β is seen. Insulin suppressed plasma ICAM-1, monocyte chemotactic protein-1, early growth response gene-1, MMP-9, tissue factor, and plasminogen activator inhibitor-1 levels 42 , The expression of the series of TLRs TLR-1, TLR-2, TLR-4, TLR-7, TLR-9 and PU.

Furthermore, endothelial nitric oxide NO synthase and the secretion of nitric oxide NO from the endothelium occur with insulin administration Insulin is, thus, a vasodilator at the arterial, microvascular, and venous levels 48 — This action of insulin is appropriate for the distribution and uptake of macronutrients postprandially at the tissue level.

The anti-inflammatory action of insulin is relevant to postprandial inflammation, as endotoxemia and TLR-4 induction are a part of HFHC-induced inflammatory changes.

The suppression of endotoxin-induced inflammation has also been demonstrated with insulin This involves the inhibition of ROS generation, lipid peroxidation, NO generation through inducible NO synthase, and macrophage migration inhibitory factor. In addition, insulin suppresses an endotoxin-induced increase in troponin I as well unpublished observation.

In obese and diabetic patients, insulin suppresses the expression and plasma concentrations of high-mobility group box-1, which functions as a proinflammatory cytokine when secreted by damaged cells through its binding to the advanced glycation end-product receptor 51 — Insulin also suppresses proinflammatory serine kinases, which interfere with insulin signaling via serine phosphorylation of IRS-1, and insulin decreases plasma free fatty acid concentration and lipolysis, thus, potentially increasing insulin sensitivity 52 , Insulin regulates the distribution, uptake, and storage of macronutrients postprandially and also modulates postprandial oxidative and inflammatory stress.

However, the magnitude of postprandial oxidative and inflammatory stress and endotoxemia, generated after the intake of HFHC meals, overwhelms the suppressive action of insulin Therefore, the prolonged, excessive consumption of the wrong choice of macronutrients would eventually result in insulin resistance.

The typical Western diet is rich in refined carbohydrates, saturated fat, and animal protein. Increased production of a highly atherogenic compound, trimethylamine- N -oxide, is seen with these diets rich in animal products, especially red meats 55 , Healthy dietary habits coupled with the partial substitution of starchy foods and red meats with foods high in plant protein and unsaturated fat are associated with positive cardiometabolic outcomes 57 , Strategies to deal with the rising prevalence of obesity and its attending complications would involve disciplined lifestyle interventions, such as the choice of appropriate foods Fig.

Inflammatory and noninflammatory foods 7 , 59 , Diets high in polyphenols and flavonoids abundant in several fruits, vegetables, and legumes are anti-inflammatory and thus, potentially anti-atherogenic 59 , 61 — Fresh orange juice consumption has been demonstrated to be noninflammatory on its own and to be anti-inflammatory when consumed with an HFHC meal.

In spite of its caloric content being entirely a result of glucose, fructose, and sucrose, orange juice is noninflammatory, largely because of its two major flavonoids: naringenin and hesperidin.

These flavonoids probably also contribute to the ability of orange juice to inhibit ROS generation, NF- κ B binding, proinflammatory cytokine expression, endotoxemia, and TLR-4 expression, induced by an HFHC meal Fig. A combination of resveratrol with muscadyne grape extracts has also been shown to inhibit oxidative and inflammatory stress induced by the HFHC meal.

This combination, in addition, prevented the fall in the antioxidant-enhancing transcription factor, Nrf-2, and suppressed the increase in its inhibitor, Keap-1, which is induced by HFHC meals. Nrf-2 acts through antioxidant response elements and modulates the expression of key antioxidant enzymes NQO-1, HO-1, and GSTP A fall in the expression of key antioxidant enzymes NQO-1, HO-1, and GSTP-1, observed after an HFHC meal, was also prevented by the combination of resveratrol and muscadyne grapes Most recently, the addition of fiber to the HFHC meal was comprehensively shown not only to prevent oxidative stress and inflammation but also to increase insulinogenesis after the meal and reduce the glycemic increase Dietary fiber also reduces endotoxemia and the induction of TLR-4 and TLR-2, the receptors for endotoxin and gram-positive bacterial products, respectively.

Fiber induces reductions in the expression of proinflammatory cytokines, such as TNF- α and IL-1 β , which significantly increase following an HFHC meal 7 , Whereas TNF- α interferes with insulin signaling, IL-1 β is toxic to the β -cell.

The induction of SOCS-3, the mediator of insulin resistance, was also prevented by the addition of fiber. Thus, energy-dense foods should be substituted with foods rich in fiber, such as fruits, vegetables, legumes, whole grains, etc.

The benefits of fiber-rich foods have been clearly demonstrated in relation to prevention of type 2 diabetes and atherosclerosis. There are additional secondary effects of fiber supplementation.

The fermentation of fiber generates short-chain fatty acids SCFAs , such as acetate, butyrate, and propionate, which have immense beneficial effects on inflammation-mediated processes and metabolic risk factors Fig.

The SCFAs activate free fatty acid receptors FFARs , which are mainly expressed in intestinal L cells. Acetate and propionate primarily activate FFAR2, whereas FFAR3 is more often activated by propionate and butyrate The release of glucagon-like peptide 1 GLP-1 and peptide YY PYY is stimulated by FFAR2 and FFAR3, and this leads to improved insulin secretion.

GLP-1 and PYY expression is decreased in diet-related conditions, such as type 2 diabetes A study demonstrated the effects of targeted delivery of propionate to the colon via the daily administration of 10 g inulin-propionate ester which results in a 2.

A substantial release of gut PYY and GLP-1 from human colonic cells was seen with propionate administration. Acute ingestion of 10 g inulin-propionate ester increased postprandial plasma concentrations of PYY and GLP-1 significantly. Long-term administration of propionate over 24 weeks resulted in considerable reductions in intra-abdominal adipose tissue, intrahepatocellular lipid content, and weight gain.

It also prevented the deterioration in insulin sensitivity observed in the inulin-control group. Some of the metabolic benefits derived from SCFAs are also a result of their role in the control of energy homeostasis.

Butyrate and propionate activate intestinal gluconeogenesis gene expression, thus regulating energy homeostasis. The activation of FFAR3 by the SCFAs, such as propionate, also promotes sympathetic activity, and this enhances energy expenditure Schematic representation of some of the effects of dietary fiber, Western diet, and bariatric surgery on oxidative and inflammatory stress.

GLP1, glucagon-like peptide 1; PPAR γ, peroxisome proliferator-activated receptor γ; PYY, peptide YY. TMAO, trimethylamine- N -oxide.

A diet high in n -6 PUFAs, which is found in abundance in plant oils, seeds, and nuts, has also been shown to decrease abdominal fat, intrahepatic fat accumulation, and peripheral insulin resistance, decreasing cardiometabolic risk factors when compared with a diet high in saturated fatty acids 58 Table 1.

A Summary of the Cardiometabolic Outcomes of Different Dietary Interventions. Abbreviations: HDL-C, high-density lipoprotein cholesterol; HOMA-IR, homeostatic model assessment for insulin resistance. Caloric restriction is crucial to sustain an ideal weight, as prolonged overconsumption of food stored as excess fat can result in obesity Furthermore, adults progressively gain weight through middle age 67 ; hence, caloric restriction is essential to maintain energy balance to compensate for this effect.

The decrease of total energy intake by avoidance of energy-dense foods from highly refined carbohydrates and fatty meals from fast foods, a reduction in total alcohol intake, and an increase in water intake has been shown to help in weight maintenance Calorie-restricted diets help achieve weight loss, with improvements seen in inflammatory and oxidative stress, insulin sensitivity, glucose and lipid metabolism, blood pressure, and cardiac function 28 , 38 , 75 Table 1.

A reversal of these effects occurred following cessation of caloric restriction, with ROS generation noted to exceed the initial baseline value before commencement of the dietary restriction. A similar observation was noted in normal subjects following restriction of macronutrient intake, which was achieved by a and hour fast.

Clearly, therefore, macronutrient intake is a major modulator of oxidative stress and inflammation. Interestingly, evolving evidence suggests that Sirtuin 1 SIRT1 , a mammalian nicotinamide adenine dinucleotide dependent deacetylase enzyme, is required for some of the key metabolic alterations seen with caloric restrictions.

Increments in cellular and tissue expression of SIRT1 in mice studies following dietary restriction have been documented, with SIRT1 protecting against high-fat diet-induced inflammation and obesity Activation of SIRT1 in some mammals is shown to substantially increase mitochondrial biogenesis in skeletal muscle and brown adipose tissue with a resultant increase in energy expenditure and protection against diet-induced weight gain This is consistent with the observation that decreased SIRT1 transcription is seen in the visceral adipose tissue of morbidly patients with obesity who have severe hepatic steatosis It is also of interest that compounds, such as resveratrol, have been shown to activate SIRT1 in mice 79 , protecting against diet-induced metabolic disorders.

However, pivotal human studies are needed in this growing field. Bariatric surgery has numerous cardiometabolic benefits. Clinically apparent resolution of insulin resistance and type 2 diabetes is seen following procedures, such as Roux-en-Y gastric bypass, even before substantial weight loss occurs.

This is partly attributable to the marked reductions in caloric intake 81 , coupled with the reductions in mediators of oxidative and inflammatory stress.

Thus, there is a reduction in ROS generation, proinflammatory cytokines, endotoxemia, and the expression of TLR-4 and SOCS-3 These changes contribute to improved insulin signalin and thus, a reduction in insulin resistance.

An interesting contribution from the data obtained from bariatric surgery is the reversal of complications related to morbid obesity and the underlying mechanisms. A recent study has also shown that the expression of genes and factors related to bronchial asthma is increased in the morbidly obese and that following bariatric surgery and weight loss, there is a reduction in asthma-related factors and genes This is consistent with the clinical observation that there is an increase in the prevalence of asthma in such patients and that following weight loss, there is a substantial reduction in respiratory symptoms.

Most recently, it has also been shown that bariatric surgery leads to a decrease in vasoconstrictors and an increase in vasodilators, thus contributing to a fall in blood pressure. Bariatric surgery also leads to a fall in neprilysin, which increases the risk of congestive heart failure in these patients Whereas a single meal may not induce changes in these genes, it is possible that persistent intake of HFHC meals may lead to an increased expression of these genes, in addition to the proinflammatory genes known to increase following such meals.

The restructuring of the gut following bariatric surgery also leads to changes in gut microbiota, with a resultant increase in the microbial production of the SCFAs Fig.

This may also contribute to reduced adiposity, weight loss, increased insulin sensitivity, and several other beneficial cardiometabolic effects Macronutrient intake has important implications for health.

A fast food-based Western diet is clearly associated with oxidative and inflammatory stress. These lead to insulin resistance and obesity, with increased atherogenicity and cardiovascular risk factors.

These risks can be avoided by the restriction of caloric intake and the choice of an appropriate diet, including fiber-rich meals, such as fresh fruits and vegetables. Disclosure Summary: P.

A satiety index of common foods. Eur J Clin Nutr. Bellissimo N , Akhavan T. Effect of macronutrient composition on short-term food intake and weight loss. Having a fried chicken breakfast sandwich, but you should try to have it once maybe twice a week, rather than for every breakfast.

Even "healthy" foods in large quantities can be unhealthy. For example, "Green Smoothies" contain large amounts of oxalates that can cause build-up and lead to kidney stones when consumed in large quantities.

Additionally, it is crucial to notice that common misconception states that eating in moderation means eating less. This IS NOT what this means. Eating "everything in moderation" means that you can have a little bit of anything, even "unhealthy" foods, but while making sure you are meeting all nutritional goals necessary for your body to stay healthy 5.

Please remember not to eat less than you need, but to make sure you are not overeating any food. Macronutrients Marcos are the three nutrients that make up much of the human diet. They are Carbohydrates, Fats, and Proteins. Despite what many people say, we need all these nutrients to support a healthy life!

These macronutrients are made up of micronutrients vitamins, minerals, etc. that our bodies need to function at their highest level. Many people track their eating habits by maintaining a balance between these macros 6. Looking at your food intake this way might help you find a balance of nutrients that can help you feel like your best self.

These ratios help many people maintain moderation and meet their necessary micronutrients in a day. Remember, everyone's body performs better with different proportions of macros, so reach out to the nutritionist at Texas Tech to learn more!

One last note on macros: it's essential to know that not all macros are created equal! An example of this would be salmon and fried chicken wings. This is because different micronutrients make up the macros that are protein in fat. For example, there are saturated fats and unsaturated fats, unsaturated being healthier because your body can break them down easier.

However, in moderation, chicken wings might be just what your body wants on a given day. You know yourself the best! We provided you with a basic understanding of what nutrients offer benefit to your body to help you begin your healthy eating journey.

RISE wants all students to live the happiest, healthiest lives possible here at Texas Tech and beyond, so hopefully these tips can help you do just that!

Many people use high sugar foods to keep their energy up and caffeine to keep going when they need rest. Too much caffeine will contribute to poor quality sleep and add to the negative effects of stress on the body.

Sugar will satisfy you in the short term, leaves you with less energy and more hungry after an hour or two. Whole foods will provide you with energy that will last for several hours. UHC Home About Toggle child menu Expand. Well-Being Resources Toggle child menu Expand.

This hard-wired ' fight or flight ' reaction was necessary millions of years ago when survival meant facing life or death threats.
