Many feel that their immunity is very poor. Falling sick too often. Breastfed babies have good immunity. Malnourished or anyone with chronic disease have less immunity end up catching infection.
There are evidence that nutrition and other lifestyle measures influence immune strength and susceptibility to infectious diseases
Diet
Eating a low-fat, plant-based diet may help give the immune system a boost. The immune system relies on white blood cells that produce antibodies to combat bacteria, viruses, and other invaders. There are many vegetarian foods that increase white blood cells.
Eating a low-fat diet may also be protective. Studies have shown that limiting dietary fat helps strengthen immune defenses. Plant-based diet has also been shown to reduce inflammatory biomarkers
Vitamins, Minerals, and Antioxidants
Studies have shown that fruits and vegetables provide nutrients—like beta-carotene, vitamin C, and vitamin E—that can boost immune function. Because many vegetables, fruits, and other plant-based foods are also rich in antioxidants, they help reduce oxidative stress thereby prevent aging.
Beta-Carotene: Beta-carotene is a powerful antioxidant that can reduce inflammation and boost immune function by increasing disease-fighting cells in the body. Excellent sources include sweet potatoes, carrots, and green leafy vegetables.
“An apple a day keeps the doctor away” Remember the proverb..
Vitamins C and E: Vitamins C and E are antioxidants that help to destroy free radicals and support the body’s natural immune response. Sources of vitamin C include red peppers, oranges, strawberries, broccoli, mangoes, lemons, and other fruits and vegetables. Vitamin E sources include nuts, seeds, spinach, and broccoli.
Vitamin D: Research shows vitamin D supplementation may reduce the risk for viral infections, including respiratory tract infections, by reducing production of proinflammatory compounds in the body. Increased vitamin D in the blood has been linked to prevention of other chronic diseases including tuberculosis, hepatitis, and cardiovascular disease. Food sources of vitamin D include fortified cereals and milks and supplements.
Zinc: Zinc is a mineral that can help boost white blood cells, which defend against invaders. Sources include nuts, pumpkin seeds, sesame seeds, beans, and lentils.
Sleep
Our bodies need sleep to rest and recharge. Without a sufficient amount of sleep, we increase our risk for developing serious health problems—like heart disease, Alzheimer’s disease, and obesity. Inadequate sleep has also been linked to suppressed immune function. One study found that those who sleep fewer than five hours per night are more likely to have have repeated infection.
