Wholefood is food eaten in or as near as possible to its natural state, with the minimum processing or cooking. Due to minimum processing or cooking, phytochemicals in wholefood are preserved. Scientists have identified thousands of phytochemicals in plants, widely known examples of phytonutrients are the carotenoids, flavonoids, polyphenols, chlorophyll, indoles, lignans, terpenes, and isoflavones. Phytochemicals are naturally occurring bioactive plant molecules or chemicals produced by plants to protect the plant from the elements of the earth, insect invasion and the solar radiation. They are found in fresh fruits and vegetables. The pytochemicals in the phytonutrients provide food resources for the cells in your body. Consumption of phytonutrients by humans is believed to protect our body from premature aging process and reduce the risk of many diseases such as cancer, heart disease, stroke, high blood pressure, cataracts, osteoporosis, diabetes and urinary tract infectio Examples of foods rich in phytonutrients include: tomatoes, green tea, grapes, red cabbages, blueberries, raspberries, blackberries, spirulina, wheat grass, tea leaves, and reishi mushroom. Spirulina are blue-green micro-algae that are a natural and rich source of nutrients, including vitamins, minerals, protein and phytonutrients (phycocyanin and chlorophyll). Spirulina is a rich source of carotenoids, especially betacarotene. Wheat grass is a "green food" source of chlorophyll, vitamins, minerals, proteins and enzymes. Despite its name, wheatgrass is gluten free and can be used by people with gluten intolerance. White tea leaves are picked before they open fully, when the buds are still covered in fine, white hairs, lending to the appearance of white tea. White tea is a rich source of polyphenols which have antioxidant and free radical scavenging properties. Reishi mushroom (lingzhi) has been renowned in China for thousands of years. It is held in high regard in Asia. It has been shown to have immune-boosting effects and anti-inflammatory properties. The primary active ingredients in reishi mushroom are two phytochemicals known as beta-glucan polysaccharides and triterpenes.
