habits, such as proper nutrition, help the body to strengthen the immune system
naturally. According to Dr. Yufang Lin, 80% of our immune system is present in our
gut that helps us to fight infectious bacteria and viruses. If our digestive system is

in foods, including olive oil, fatty fish, and nuts is essential to stimulate the immune
system. Such foods are rich in zinc, vitamin C, and other antioxidants, help to reduce
inflammation and fight pathogens. Adults and children are more susceptible to
infection due to a weak immune system. According to a scientific study published
in the journal Frontiers in Physiology, a healthy diet with regular 400 IU vitamin D
supplement increases the number of disease-fighting cells such as T cells.
Certain foods affect our immune system adversely, such as processed and fried
foods. Healthcare professionals suggest eating a whole food diet, including
fermented foods, such as sauerkraut, yogurt, kefir, and miso in a regular diet. Such
foods help to enhance the growth of beneficial bacteria in the gut and support the
immune system to fight infection.
A low-fat and plant-based diet helps to boost the immune system. The immune
system depends on the activity of white blood cells that synthesize antibodies to fight
viruses, bacteria, and other pathogens. Fresh fruits and green vegetables help us to
intake a high number of vitamins that support white blood cells.
Studies have shown that the intake of a low-fat diet is proactive and aids to
strengthen immune defenses. A high-fat diet may impair the function of white blood
cells, and oils may alter the microbiota in our gut that helps in immunity. Similarly,
maintaining a healthy weight improves the immune system. Obesity is linked with a
high risk of viral infections, including pneumonia. For weight loss, a plant-based
diet is very beneficial because it is rich in fibers, which aids fill you up, without
increasing extra calories. Fiber may also decrease BMI, which is associated with

play a vital role to boost up the immune system. According to scientific research
published in the British Medical Journal, claim that a moderate daily supply of
vitamin D protects the body from various types of viruses and bacteria. If an
individual has a normal range of vitamin D in his body, then a daily supplement of
about 600 to 800 IU is enough.
