Advertisement for a healthy diet to possibly reduce cancer risk. An average 35% of human cancer mortality is attributed to the diet of the individual. [9] Studies have linked excessive consumption of red or processed meat to an increased risk of breast cancer, colon cancer, and pancreatic cancer, a phenomenon which could be due to the presence of carcinogens in meats cooked at high temperatures.
Aging skin is characterized by wrinkles, loss of skin flexibility, laxity, and having a rough appearance in the skin texture. Prevalent throughout the body, loss of collagen can also contribute to numerous other disorders such as joint pain , weakened hair and nails , reduced bone density , gastrointestinal issues , and reduced muscle mass .
The term DNA glycation applies to DNA damage induced by reactive carbonyls (principally methylglyoxal and glyoxal) that are present in cells as by-products of sugar metabolism. [13] Glycation of DNA can cause mutation, breaks in DNA and cytotoxicity. [13] Guanine in DNA is the base most susceptible to glycation. Glycated DNA, as a form of ...
The free radicals are due to the action of UV light on AGE (advanced glycation end-products) as a result of the reaction of DHA with the skin, and the intermediates, such as Amadori products (a type of AGE), that lead to them. AGEs are behind the damage to the skin that occurs with high blood sugar in diabetes where similar glycation occurs. [28]
Stomach cancer is more common in Japan due to its high-salt diet. [9] [11] Dietary recommendations for cancer prevention typically include weight management and eating a healthy diet, consisting mainly of "vegetables, fruit, whole grains and fish, and a reduced intake of red meat, animal fat, and refined sugar."
In later years, the free radical theory was expanded to include not only aging per se, but also age-related diseases. [11] Free radical damage within cells has been linked to a range of disorders including cancer, arthritis, atherosclerosis, Alzheimer's disease, and diabetes. [13]
Skin cancer is the most commonly diagnosed form of cancer in humans. [11] [12] [13] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. [1] The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
