This review focuses on data indicating that the functions of the human immune system depend on the intake of micronutrients, which can act as antioxidants.

Recent clinical trials have found that antioxidant supplementation can significantly improve certain immune responses. Specifically, supplementation with vitamins C, E, and A or beta-carotene increased the activation of cells involved in tumor immunity in the elderly.

Supplementation with the antioxidant vitamins also protected immune responses in individuals exposed to certain environmental sources of free radicals. Supplementation with vitamin A, a relatively weak antioxidant, decreases morbidity and mortality associated with measles infections in children.

Getting adequate sleep and managing stress can be just as important as healthy eating to prevent the flu. Even if you eat healthily, get plenty of rest, drink adequate fluids and manage your stress, you may still catch the flu. If so, your illness may not last as long, and you may not feel so bad.

According to the National Institutes of Health, there are many healing benefits of chicken soup. Your favorite recipe likely has properties that fight inflammation, promote hydration and get mucus flowing.

Drink plenty of liquids, such as water, broth or sports drinks with electrolytes. When taken before cold symptoms start, vitamin C may shorten the duration, but it doesn't keep you from getting sick.

Abstract One of the most widely accepted theories proposed to explain ageing is the free radical theory, according to which oxygen-derived free radicals cause age-related impairment through oxidative damage to biomolecules, with mitochondria being the main target of free radical attack.

Unfortunately, although the role played by free radical to the pathogenesis of ALS has been demonstrated, antioxidants did not have any effect to prevent or slow down its progression.

The field of antioxidants is moving rapidly. About 20 years ago the hypothesis that diet might have a substantial influence on the development of some pathologies, such as cancer, has been raised by many scientists. In this light, during the last decade, efforts have been made to analyze the effects of plant food and synthetic antioxidants on the development and prevention of chronic diseases.

Nowadays, antioxidants are used on a large scale to try to obtain and preserve optimal health. While there is no doubt that the correct balance between endogenous and exogenous antioxidant capacity is essential to life, the curative power of antioxidants has often been overestimated.

In fact, according to the popular idea "if one is good two is better", antioxidants are taken in excess too often and the risk to originate diseases instead of preventing them is quite high. It is noteworthy to underlie that as for all drugs, antioxidants may give important side effects if not correctly used or in combination with other drugs.

Vitamin A, E and β-carotene for instance, have been shown to have pro-oxidant effects at higher doses or under certain conditions [ 39 ]. Another point of criticism is the possibility to take experimental results "from the bench to the bedside". In fact, although the promising results obtained by in vitro experiments, the use of antioxidants in the treatment of human disease states has not been as successful as might have been envisaged due to intrinsic pharmacokinetic or pharmacodynamic limitations.

In addition, conclusions on beneficial effect of antioxidant are often drawn from studies conducted with synthetic antioxidant supplement, whereas fruits and vegetable are a complex mixture of antioxidant, as well as other potentially beneficial micronutrients and macronutrients, which may, thus, work with different kinetics and dynamics [ 89 ].

In conclusion, the correct use of antioxidants may be useful to prevent free radical-related disorders. However, the repair of existing critical structural damage may be beyond the possibilities of antioxidants and therefore they may not be considered to be useful in therapeutic clinical applications, where their limits and eventual side effects must be better understood.

Should I take a supplement? Antioxidants appear to have the most benefit when you eat them in whole foods. For example, strawberries and raspberries contain an antioxidant called ellagic acid, which is poorly absorbed in supplement form. The best antioxidant diet, one rich in fruits, vegetables and whole grains, could also be the best diet to prevent heart disease, cancer, type II diabetes, and age-related diseases.

Therefore, the present paper will review the effects of dietary antioxidants on immune cell function and the impact on protection against infectious microorganisms. Abstract Natural antioxidants may be defined as molecules that prevent cell damage against free radicals and are critical for maintaining optimum health in both animals and humans.

Publication types Review. Antioxidants are powerful compounds in our foods that keep our immune systems working strong. Here are a few: Vitamin C is found in citrus, kiwi, strawberries, bell peppers and broccoli. Vitamin E is contained in almonds, avocados and olive oil.

Beta-carotene creates vitamin A, important for vision and bone health. Good sources are carrots, sweet potatoes, kale, chard and papayas. Lycopene is found in red fruits and vegetables like tomatoes, papaya and watermelon. Lutein and zeaxanthin are found in dark green leafy veggies like spinach, kale, collard greens and broccoli and may help slow the progress of age-related macular degeneration in the eyes.

Anthocyanins are found in blue and purple foods like blueberries, raspberries, plums, pomegranates, eggplant, and red cabbage. Oakland San Pablo Avenue Oakland, CA Email Us. San Francisco Polk Street San Francisco, CA Email Us.

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.

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.
