A balanced diet can provide us with a strong immune system. Antioxidant food is central to this, because generally it strengthens the body and fight viruses.

For example:
• Fatty fish (sardines, salmon, mackerel, trout, etc.) and nuts (pistachios, sesame seeds, flaxseed, etc.) contain omega-3 fatty acids, which help to stimulate the body as well as good mood. Fatty fish also contain vitamin D, which is very useful for our good health.
• Raw red and green peppers, kiwi, broccoli, strawberries, lemon and oranges contain Vitamin C, one of the body’s best allies against viruses.
• Egg, fish and liver contain vitamin A, while carrots, sweet potato, tomato and spinach contain beta-carotene, the precursor form of vitamin A, which also contributes to the body’s defense.
• Olive oil and dark leafy vegetables are sources of vitamin E, which ensure the proper functioning of the immune system.
• Molluscs, cereals, meat, rice, sunflower seeds etc. contain selenium, while shellfish, beef, lamb, liver, pumpkin seeds, nuts and legumes contain zinc. Selenium and zinc are two trace elements that enhance the body’s defenses.
• The immune system is further enhanced by: honey (with its anti-bacterial properties), garlic, and probiotics (generally fermented dairy products that supply the body with beneficial bacteria that fight various viruses).

Washing hands
As colds and flu viruses are transmitted by hand contact and droplets released into the air by coughing and sneezing, hand washing with warm water and soap is an important precaution as well as avoiding touching our eyes or our nose with our hands.

We also ensure that we incorporate exercise into our daily life (30 minutes fast walking or biking, yoga, etc.), as it plays an important role in boosting the immune system and our overall health.

And in order to preserve our body during the flu season, it is advisable to avoid too much sugar, alcohol, and even the stress that usually puts on our defenses. Good hydration is also shown to be important, by consuming as many liquids as possible – water and juices.

Finally, it’ s good that some groups of people get the flu vaccine every year, as they are more vulnerable and more at risk of complications, such as pneumonia.
