This is the most common type of cancer in men (with the exception of skin) both in the United States and in Europe, where this is the third leading cause of death after pulmonary and colorectal cancers.
In Spain, 18,872 new cases of prostate cancer (81.25 cases per 100,000 inhabitants) are found every year, according to the co-chair of the San Rafael Department of Urology at Madrid, Edilberto Fernandez, as well as the head of medical oncology at the MD Anderson Center in Madrid, Enrique Grande, in La Comida Saludable (Books Dome).
According to him, with some treatments being considered due to their significant number of side effects, it would be desirable to create prevention mechanisms that act on the disease, among which nutritional factors can be found.
"We have identified a range of risk factors involved in prostate cancer carcinogenesis, including age, race, various genetic factors and diet." Prostate cancer is very associated with the elderly, rarely before the age of 40 and the mean age of occurrence in Spain is 74 years old ", they stressed.
In addition, they show that there are significant geographical differences in the incidence of prostate cancer worldwide, which they think may mean "Some nutritional factors can influence the development of cancer by playing an activating role or as an inhibitor of carcinogenesis."
Although they warn that the effects of diet on prostate cancer are currently a matter, they believe that specific dietary changes should start at an early age to have an effect. Thus, from the point of view of the prevention of prostate cancer, they argue that, among others, they are considered as potential protective agents against prostate cancer:
– Licopeni, due to their antioxidant potentials, free radicals neutralizing, and carotenoids, vitamin A predecessors. Various studies show a 20% reduction in the risk of prostate cancer suffering from a diet rich in these substances. They can be found in tomatoes, watermelon, grapefruit and other fruits and vegetables.
– Crossed vegetables because they contain plenty of bra, micronutrients (vitamin C, E and folate) and chemical products (carotenoids, phenols, isothiocyanates, indole) with biological activity like anti-carcinogens. Absorption of fruit and vegetables is associated with a reduction in the risk of many cancers. Consumption of high doses of vegetables, especially cruciferous, such as broccoli and color, has a diminishing effect on the risk of prostate cancer. They can also be found in carrots, spinach, garlic, cabbage, leeks, onions, green lettuce and green asparagus.
– Vitamin E supplements In some studies, they have shown a reduction in incidence and mortality in prostate cancer, although in others they have been shown to be ineffective. It can be found naturally in products such as sunflower seed, red pepper, peaches, almonds, peanuts, aromatic herbs such as basil and oregano, apricots, green olives, spinach, taro or hazelnuts.
– SeleniumIt also presents controversial results about its role as a prostate cancer protective agent in several studies. At various doses, it exhibits a variety of anti-anancological properties, including antioxidant protection, cessation of carcinogenic metabolism, immune stimulation, and cell death. Some studies have shown a reduction in the incidence of prostate cancer. It is found in nuts (nuts, hazelnuts), zucchini, vegetables, cucumbers, garlic, asparagus, legumes, cereals, fruits, mushrooms, meat, seafood, eggs, milk and derivatives.
– Knowing vitamin D it is considered a risk factor for the development of prostate cancer as its metabolites have a protective effect against carcinogenesis.
– Caffeine and Phenolic Acid, active ingredients of coffee, have antioxidant activity. Studies show that men who regularly consume coffee have a lower risk of developing advanced or lethal prostate cancer.
– the Mediterranean diet, considered today to protect against many types of cancer and cardiovascular disease, has a high content of fruits, vegetables, pasta and includes moderate wine consumption, and this combination is excellent to recommend it to the population.
Instead, Increased Prostate Cancer Factors:
– Calcium, because it suppresses the endogenous synthesis of vitamin D, which inhibits the proliferation of prostate neoplastic cells. It also increases the blood levels of certain hormones that promote tissue growth and are associated with an increased risk of prostate cancer. The increase in risk is small and occurs in cases of high intake of dairy products, which have seen a relative increase in some more aggressive tumor variants. Milk, dairy products and eggs are rich in calcium.
– Zinc it may play a role in suppressing the growth of neoplastic prostate cells and inhibiting tumor invasion. Long-term intake of zinc as an isolated supplement or as part of multivitamin preparations is associated with an increased risk of prostate cancer. It can be found in cocoa, watermelon, lamb, oysters, peanuts, pumpkin seeds, butter, calf liver, wheat germ.
– Diet rich in fat may increase the risk of prostate cancer. The ingestion of large amounts of alpha-linolenic acid and the low amount of linolenic acid, a combination that occurs with red meat and some dairy products, seems to be responsible for this increased risk. Obese patients have a higher risk of prostate cancer. Therefore, saturated fats or animal fats and butter should be avoided in the diet.
– Meat is one of the main fats, so it is difficult to distinguish between correlation with meat intake and fat intake. Meat cooking at high temperature produces products with potentially carcinogenic effects. In addition, N-nitroso compounds are formed endogenously or by preservatives added to the processed meat also with carcinogenic potential and free radicals of iron-containing products. Therefore, the intake of red and processed meat is associated with a high risk of prostate cancer and, in particular, metastatic prostate cancer.
– Additives with folic acid they are associated with a higher incidence of prostate cancer. Green vegetables, fruits, grains, nuts, and meat are rich in this substance.
