Still, the same protocols were followed to derive each macronutrient from different foods across all cycles.

Fat intake and energy levels -

There are nine essential amino acids see table 3 , which the body cannot make or cannot make enough to meet the needs. Therefore, they are essential components of our diet. Generally, protein from the animal source is considered as complete protein since it contains all the essential amino acids, whereas protein from the plant source, except soy protein, is limiting in one or more essential amino acids.

For example, grains are limited in lysine and legumes are limited in methionine, two of the nine essential amino acids. For strict vegetarians, it is recommended that their diet should include a mix of foods from various plant sources, so that different foods complement each other i. the essential amino acid missing from one source is supplied by another , making a meatless diet to be one with all the essential amino acids.

Protein deficiency is not common in Hong Kong. However, Protein-energy Malnutrition PEM is one of the world's most widespread malnutrition problems, which is prevalent in Africa.

At the other end, excess intake of protein offers no extra health benefits as additional protein that is not used by the body will be converted to fat. During the conversion, protein is being broken down and excess nitrogen is being excreted, thereby putting extra stress on the liver and kidneys.

This is a particular concern for individuals with kidney diseases. Thus, patients with kidney disease are often advised to consume a diet with protein that is of good quality, but in limited quantity.

According to the Chinese Recommended Nutrient Intake RNI , an adult male and female with light physical activity levels should consume 75 g and 65 g of protein per day respectively. Children, teenagers, pregnant and lactating women need more proteins for growth.

Meat, poultry, fish, eggs and dry beans are good sources of protein. With reference to the Food Pyramid, it is the third-level up under the "Eat Moderately" level. In terms of actual amount, an adult should eat taels equivalent to g of meat a day. In the next issue, we will examine another macronutrient — Carbohydrates: the body's preferred energy source.

Food Safety Focus 29th Issue, December — Food Safety Platform Nutrient and Health - Energy and Protein Reported by Ms. Jacqueline FUNG, Scientific Officer, Risk Communication Section, Centre for Food Safety Starting from this issue, the nutrition series will focus on selected nutrients.

Over the last 50 years, many people have moved from a moderate fat to a low fat diet, based on recommendations from health organizations. However, the Dietary Guidelines for Americans no longer specifies an upper limit for how much total fat you should consume.

This article takes a detailed look at different types of fat and provides suggestions for how much to eat per day.

Along with protein and carbs , fat is one of the three macronutrients in your diet. You consume fat in the form of triglycerides.

A triglyceride molecule consists of three fatty acids attached to a glycerol backbone. The fatty acids contain chains of carbons and hydrogens. One way to classify fats is by the length of their carbon chains :. Most of the fats you eat are long-chain fatty acids.

Short-chain fatty acids are mainly produced when bacteria ferment soluble fiber in your colon, although milk fat also contains small amounts. However, the liver takes up short-chain and medium-chain fats directly and stores them as energy.

Summary: Fats are one of the three macronutrients. The body absorbs them from food and uses them for energy and other functions.

Summary: Fats provide a number of benefits for your body, including serving as an energy source, regulating hormones and genes, maintaining brain health, and making food tastier and more satisfying.

Fatty acids are grouped according to the number of double bonds between carbons in their structures. MUFA food sources are typically liquid at room temperature and fairly stable for cooking purposes.

The most common MUFA is oleic acid, which olive oil contains in high amounts. Monounsaturated fat is linked to several health benefits, including a reduced risk of serious diseases such as heart disease and diabetes 5 , 6 , 7. One review of 24 controlled studies found diets high in monounsaturated fat lead to significantly lower blood sugar, triglycerides, weight and blood pressure levels, compared to high carb diets.

The high monounsaturated fat diets also increased HDL good cholesterol levels 7. In one study, people felt fuller and took in fewer calories for the next 24 hours after consuming bread alongside oil rich in oleic acid, compared to bread that contained less 8.

They can be divided into groups depending on the location of the double bonds. These include omega-3s and omega-6s. Studies have found that long-chain omega-3 fats have benefits for inflammation, heart disease, diabetes, depression, and other health conditions 9 , 10 , 11 , Although you need some omega-6 fats, they can contribute to chronic inflammation if you consume too much, especially if omega-3 PUFA intake is low 13 , 14 , Omega-6 fats are very common in modern-day diets.

On the other hand, omega-3 fats are usually consumed in much smaller amounts. Significantly, researchers report that the evolutionary diet of humans provided a ratio of omega-6 to omega-3 fats between 1-to-1 and 4-to SFA intake can raise LDL bad cholesterol levels in some people, although this depends in part on the specific fatty acids consumed.

It should also be noted that HDL good cholesterol typically goes up as well For example, studies suggest that the medium-chain triglycerides in coconut oil and palm oil may boost metabolic rate and reduce calorie intake 22 , In a trans fats molecule, hydrogens are positioned across from each other rather than side by side.

Small amounts of trans fats occur naturally in dairy and other animal foods. However, nothing is natural about the trans fats used in processed foods. These trans fats are produced by adding hydrogen to unsaturated fats to create a product that functions more like a saturated fat.

Consuming trans fats can lead to a number of health problems. Artificial trans fats are linked to inflammation, unhealthy cholesterol changes, impaired artery function, insulin resistance, and excess belly fat 25 , 26 , 27 , 28 , Research has linked the intake of trans fats with a higher risk of cardiovascular disease Trans fats are often found in margarine and other processed spreads.

Food manufacturers sometimes add them to packaged products, such as crackers, to help extend shelf life. Summary: Fats are grouped by the number of bonds in their carbon chains. Aside from trans fats, most fats have beneficial or neutral effects on health.

However, a high omega-6 to omega-3 ratio may cause problems. The appropriate amount of fat to eat will depend on your calorie requirements for weight loss or maintenance.

You can use this calculator to determine your calorie needs to lose weight or maintain your weight, which is known as your daily calorie goal. Here are a few examples of suggested daily fat ranges for a low fat diet, based on different calorie goals:.

Studies show higher fat diets, such as low carb and Mediterranean diets, offer many health benefits and may be a better choice than lower fat diets for some people.

A ketogenic diet :. Here are a few examples of suggested daily fat ranges for a low-carb or ketogenic diet, based on different calorie goals:. The Mediterranean diet includes a wide variety of plant and animal foods such as:.

Here are a few examples of suggested daily fat ranges for a Mediterranean diet, based on different calorie goals:.

Summary: How much fat you eat per day should be based on the type of diet you follow and your calorie needs for weight loss or maintenance.

Fortunately, many delicious foods can provide the fat you need. Monounsaturated fats are found in most plant and animal foods, but some foods are especially rich in them.
