In recent years, laboratory researchers have discovered the existence of phytochemicals, otherwise known as phytonutrients. These are substances which protect the human body against a variety of diseases, including cancer. Twenty phytonutrients are currently known to exist (see Table below); and they are only found in fruits and vegetables. Here are the names of these substances, plus the foods you would need to eat in order to absorb them into your body.Phytochemicals not only provide colour, texture, and flavour to plant foods; they also protect plants against microorganisms and insects. When eaten, these substances protect us against disease! A high intake of fruit and vegetables protects the human body against various cancers, coronary heart disease, and stroke. A Harvard study found that the risk of a stroke, alone, was reduced by 31%. A Finnish study found that phytochemicals reduce the likelihood of death by 35%.
For example, there are over 600 types of carotenoids in plants. Rich in antioxidants, they reduce or eliminate cancers in research animals, stimulate the immune system, and protect against age-related macular degeneration. Another example is the glucarates (found in the white portion under the peel of citrus) which protect against breast cancer. (Source: Natural Remedies Encyclopedia)
