Antioxidants are molecules that can prevent or slow down the damage, caused by free radicals.
Although it is the most abundant antioxidant found in human cells, barely anyone seems to know much about this (unless you’re a medical or nutritional professional). And that is because glutathione can be made in the body, providing there are good sources of protein available.
However, glutathione levels drop with age and many people of the age 65+ have considerably low levels of glutathione available (8). It is therefore key to make sure you have good sources of complete proteins available, such as chicken, turkey, fish, eggs and so on.
If you feel below par and your immunity defenses are already lowered, it may be a good idea to take an extra supplement. Make sure you consult a medical or nutritional professional for your unique body needs.
When it comes to vitamin A, think eyes, skin and respiratory tract. This antioxidant is effective in supporting people through respiratory tract infections and can help reduce the severity of the infection (9).
Vitamin A precursors are found in orange foods, such as carrots, squash, pumpkin, sweet potatoes, mango, apricot and spinach.
If you’re not already taking vitamin C to support your immune system through the flu season, you may want to start right now. Vitamin C can decrease the duration of colds, improve immune cell function and can support blood vessels and skin (10).
Vitamin C can be abundantly found in foods, especially fruit and veg. Some of the popular sources include citrus fruit, peppers, cabbage, potatoes, berries and sprouts.
A flavonoid, found in onions, apples and citrus fruit that can reduce inflammation and protect against cell damage. Especially effective for dealing with issues relating to breathing pathways, hay fever and viral infections (11).
As you can see there is plenty you can start doing NOW to boost your immunity and your body’s natural defenses. Keep focusing on filling your plate with rainbow colours and variety and you’re halfway there! And if you’re interested in adding additional supplementation, make sure you contact a medical or nutritional professional to help you get the best, most suitable options for your body.
