[Sports Nutrition Lounge] Phytonutrients & Performance

There are two antioxidant defense systems in our body: Enzymatic (e.g. SODs, Catalase, Glutathione systems) and non-enzymatic (e.g. vitamin C, Vitamin E, Glutathione, Melatonin, Uric acid)

Phytonutrients refer to the natural chemical components in plants which are used to protect plants from external attacks. Research found that these substances can help improving human physiological functions and preventing diseases

High intensity exercise induces oxidative stress, inflammation, free radical-mediated muscle damage and development of neurodegenerative diseases. Consuming adequate phytonutrients (polyphenols), may beneficial to exercise performance, enhance post-exercise recovery and training adaptation

Fresh fruits, vegetables, beverages (juices, tea, coffee), nuts and cereals are rich in natural antioxidants. Prioritize choosing fruits and vegetables with different colours (red, orange, green, blue-purple, and white) daily

Long-term intake of high doses of antioxidant supplements, especially vitamins C and E, will reduce training adaptation
