Fruits and vegetables are essential to a healthy diet but protein is important too. Many of us remember being fed chicken soup as a cold remedy when we were children. Vitamin B6 is important for immune function since it helps with the formation of new red blood cells.

Omega-3 fatty acids are important for immune function. These nutrients are found in most seafood such as salmon, tuna and mackerel. Omega-3 fatty acids can help to reduce inflammation and boost the function of immune cells.

Plant-based protein options like beans, peas, chickpeas, nuts and seeds offer the body a boost of healthy fats and protein while also being nutrient rich. Nuts are rich in magnesium, iron, vitamin E and vitamin B6. In addition to fruits, vegetables and lean meats there are many other foods that can help to boost the immune system.

Actually, some of the most beneficial foods are listed below. Nuts and seeds are an excellent source of nutrients that can help to support immune function. They are rich in protein, healthy fat and fiber. They are also filled with vitamins and minerals like vitamin E, magnesium and zinc.

Fermented foods like kimchi, kefir, yogurt, and sauerkraut support your microbiome since they contain active cultures and provide the body with probiotics. Your body contains all types of healthy bacteria and fermented foods help to boost the health of these bacteria to support overall health as well as immune health.

Herbs and spices like turmeric and oregano are great for immune function. Many natural supplements are made using herbs and spices—and for good reason. You can easily incorporate herbs and spices into your meals to add an extra boost of nutrients as well as extra flavor. There are many different delicious meals that are packed with immune-boosting nutrients.

The great thing about soup is that it can be made with health-supporting bone broth and you can literally throw in just about any other nutritious foods.

Start by sauteeing the vegetables we recommend using carrots, sweet potatoes, bell peppers, onions, garlic and celery. While you do that, cook the chicken in the oven. Once the chicken is cooked you can shred it or pull it apart.

Add the chicken and broth to the vegetables then top with some immune-boosting herbs like thyme and rosemary. Make a colorful stir fry using protein-packed quinoa and a variety of brightly colored vegetables like broccoli and red bell pepper.

Start by cooking the quinoa. Then in a saute pan, cook the vegetables. Mix in the cooked quinoa and top with ginger and garlic for added nutritional benefits. Salmon is rich in omega-3 fatty acids which support immune health and help to lower inflammation. Start by placing the salmon on an aluminum foil or parchment paper-lined baking sheet.

Top the salmon with some lemon juice, olive oil and fresh dill. Season lightly with salt, pepper and garlic. Bake for 30 minutes at degrees. You can also serve this dish with some cooked vegetables and wild rice. A smoothie is a great way to blend a variety of different nutritious ingredients.

To make this smoothie, blend together kale and berries with some coconut water or plant-based milk. You can also add some nutritious herbs like ginger and turmeric for extra benefits.

Kale is a superfood , full of nutrients like vitamin A, vitamin B6, vitamin K, folate and fiber and berries are packed with powerful antioxidants like vitamin C.

It is also believed that a Western diet high in refined sugar and red meat and low in fruits and vegetables can promote disturbances in healthy intestinal microorganisms, resulting in chronic inflammation of the gut, and associated suppressed immunity.

The microbiome is an internal metropolis of trillions of microorganisms or microbes that live in our bodies, mostly in the intestines. It is an area of intense and active research, as scientists are finding that the microbiome plays a key role in immune function. The gut is a major site of immune activity and the production of antimicrobial proteins.

A high-fiber plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes appear to support the growth and maintenance of beneficial microbes. Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity.

These fibers are sometimes called prebiotics because they feed microbes. Therefore, a diet containing probiotic and prebiotic foods may be beneficial. Probiotic foods contain live helpful bacteria, and prebiotic foods contain fiber and oligosaccharides that feed and maintain healthy colonies of those bacteria.

Animal studies have found that deficiencies in zinc , selenium , iron , copper, folic acid , and vitamins A , B6 , C , D , and E can alter immune responses.

Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections. Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients.

However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs. In these cases a vitamin and mineral supplement may help to fill nutritional gaps. Studies have shown that vitamin supplementation can improve immune responses in these groups.

The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases. This causes a higher risk of poorer outcomes if the elderly develop chronic or acute diseases.

In addition, about one-third of elderly in industrialized countries have nutrient deficiencies. Diet variety may also be limited due to budget constraints or lower interest in cooking for one person; poor dentition; mental impairment; or lack of transportation and community resources to obtain healthy food.

Megadose supplements many times the RDA do not appear justified, and can sometimes be harmful or even suppress the immune system e. Remember that vitamin supplements should not be considered a substitute for a good diet because no supplements contain all the benefits of healthful foods.

Several herbal supplements have been suggested to boost immune function. What does the research say? Diet Review: Anti-Inflammatory Diet.

What Is Our Immune System? These barriers include: Skin that keeps out the majority of pathogens Mucus that traps pathogens Stomach acid that destroys pathogens Enzymes in our sweat and tears that help create anti-bacterial compounds Immune system cells that attack all foreign cells entering the body Adaptive or acquired immunity is a system that learns to recognize a pathogen.

Other conditions that trigger an immune response Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity. What factors can depress our immune system? Older age: As we age, our internal organs may become less efficient; immune-related organs like the thymus or bone marrow produce less immune cells needed to fight off infections.

Aging is sometimes associated with micronutrient deficiencies, which may worsen a declining immune function. Environmental toxins smoke and other particles contributing to air pollution, excessive alcohol : These substances can impair or suppress the normal activity of immune cells.

Excess weight: Obesity is associated with low-grade chronic inflammation. Fat tissue produces adipocytokines that can promote inflammatory processes.

Chronic diseases: Autoimmune and immunodeficiency disorders attack and potentially disable immune cells. Chronic mental stress: Stress releases hormones like cortisol that suppresses inflammation inflammation is initially needed to activate immune cells and the action of white blood cells.

Lack of sleep and rest: Sleep is a time of restoration for the body , during which a type of cytokine is released that fights infection; too little sleep lowers the amount of these cytokines and other immune cells. Does an Immune-Boosting Diet Exist? Probiotic foods include kefir, yogurt with live active cultures, fermented vegetables, sauerkraut, tempeh, kombucha tea, kimchi, and miso.

Prebiotic foods include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas , and seaweed.

However, a more general rule is to eat a variety of fruits, vegetables , beans , and whole grains for dietary prebiotics. Chicken soup as medicine? Is there scientific evidence that it aids in healing? But when breaking down its ingredients, it does appear a worthwhile remedy to try.

Second, it provides fluids and electrolytes to prevent dehydration, which can easily occur with a fever. Lastly, a traditional chicken soup recipe supplies various nutrients involved in the immune system: protein and zinc from the chicken, vitamin A from carrots, vitamin C from celery and onions, and antioxidants in the onions and herbs.
