Bone cancer is the cancer originating primarily from the bone and its surrounding tissue. However, the most common form of cancer in the bones is from metastasis from another primary cancer at a different organ. Osteosarcoma is the most common primary bone cancer followed by chondrosarcoma, Ewing’s sarcoma, fibrosarcoma and others.
Phytonutrients are natural compounds produced by plants for their protection. They help plants repel harmful insects, protect them from diseases, draught, ultraviolet rays, and pollutants. Until recently phytonutrients were not considered as important nutrients for humans; however, they are now thought to be necessary to sustain human life. Some examples of common phytonutrients are curcumin (which is an active component in turmeric), resveratrol (which is found in peanuts, pistachios, grapes, red and white wine, blueberries, and cocoa and dark chocolate), and quercetin (which is an active component present in red onions, apples, and peppers). It has been shown that several of these phytonutrients present in fruits and vegetables can reduce the incidence of chronic diseases such as diabetes, hypertension, atherosclerosis, and cancer.
The widely available extract from green tea is a combination of different phytonutrients (polyphenols) present in the tea leaves, which claim various health benefits. Green tea polyphenols have potent antioxidant and anti-inflammatory properties contributing to their anti-cancer and cardiovascular benefits and support of overall health. Recent research also shows that green tea offers health benefits in several conditions, such as rheumatoid arthritis, atherosclerosis, Alzheimer's disease, and so on.
According to recent dietary guidelines, healthy people should consume at least 5-9 (and sometimes up to 13) servings of fruits and vegetables daily (one serving equals 1 cup). Especially recommended are colorful fruits and vegetables rich in vitamins and various phytonutrients.
Curcumin is the most abundant natural phenol (curcuminoid) present in the Indian curry spice, turmeric, and it gives turmeric its yellow color. Turmeric powder is obtained from the rhizomes of the Curcuma longa plant. Turmeric powder is used extensively in South-Asian cooking and food preservation. Due to its various medicinal properties, turmeric is still used in Ayurvedic medicine for skin, respiratory, and gastrointestinal ailments, liver disorders, muscle sprains, joint pains, and wound healing. In the past few decades, curcumin has been studied to evaluate its anti-oxidant, anti-inflammatory, and immune modulation properties.
