Antioxidants and ‘Superfoods’
For a food to be termed ‘superfood’, it must hit the top of the list of foods that have a high content of nutrients and antioxidants. Antioxidants stop the damaging effects of free radicals that are formed on exposure to substances such as alcohol, stress, poor diet, highly processed and refined foods, drugs, medications, smog, chemicals, radiation, and free radicals are also formed during normal physiological processes such as fighting infections. Free radicals can make us feel flat, sluggish and tired. They also impair our immune system, increase inflammation and reduce our general health, which can lead to disease and illnesses such as cancer.
The antioxidant values in foods are measured using a ORAC level (Oxygen radical absorbance capacity), for example goji berries have approximately ten times the ORAC level than standard berries, and garlic has approximately four times the ORAC level than onion.
Foods with a high ORAC value help your body reduce oxidative damage, inflammation, and are also anti-aging. Antioxidants provide antibacterial, antiviral and digestive supportive – so consuming these foods every day as part of a balanced diet reduces your risk of cancer, increases your energy, immune system, helps reduce cholesterol and supports your digestive health.
