Artemis P. The countries around the Mediterranean basin have different diets, religions and cultures. Their diets differ in the amount of total fat, olive oil, type of meat and wine intake; milk vs. Extensive studies on the traditional diet of Greece the diet before indicate that the dietary pattern of Greeks consists of a high intake of fruits, vegetables particularly wild plants, nuts and cereals mostly in the form of sourdough bread rather than pasta; more olive oil and olives; less milk but more cheese; more fish; less meat; and moderate amounts of wine, more so than other Mediterranean countries. Analyses of the dietary pattern of the diet of Crete shows a number of protective substances, such as selenium, glutathione, a balanced ratio of n-6 : n-3 essential fatty acids EFA, high amounts of fiber, antioxidants especially resveratrol from wine and polyphenols from olive oil, vitamins E and C, some of which have been shown to be associated with lower risk of cancer, including cancer of the breast. These findings should serve as a strong incentive for the initiation of intervention trials that will test the effect of specific dietary patterns in the prevention and management of patients with cancer. The health of the individual and the population in general is the result of interactions between genetics and a number of environmental factors. Nutrition is an environmental factor of major importance 1 — 4. Our genetic profile has not changed over the past 10, y, whereas major changes have taken place in our food supply and in energy expenditure and physical activity 5 — Today industrialized societies are characterized by the following: 1 an increase in energy intake and decrease in energy expenditure; 2 an increase in saturated fat, n-6 fatty acids and trans fatty acids and a decrease in n-3 fatty acid intake; 3 a decrease in complex carbohydrates and fiber intake; 4 an increase in cereal grains and a decrease in fruit and vegetable intake; and 5 a decrease in protein, antioxidant and calcium intake 5 —
The latter are devoid of the fiber and other healthier components of complex carbohydrates. You may wonder why you have spent so many words, for thirty years or so, to enhance a diet that does not need any introduction. Everyone is talking about the Mediterranean diet, but few are those who do it properly, thus generating a lot of confusion in the reader. Ashfield-Watt PA.
When the relations between the intake of oleic acid and any health item are analyzed within a Western cohort, investigators mainly analyze the relations with beef and pork consumption. This conversion dependent on the elongase and desaturase enzymes is usually limited due to an excess of omega-6 fats which compete for the same enzymes in Indian diets [ ]. In , a study conducted by the National Institutes of Health showed that moderate physical activity is associated with a decrease in mortality from cardiovascular disease The results of the Seven Countries Studies and the Lyon Heart Study based on a modified diet of Crete indicate that a Paleolithic-type diet such as the traditional Greek diet balanced in n-6 and n-3 fatty acids and rich in vitamins C and E fruits and vegetables is associated with decreased rates of heart disease and cancer more so than any other diet or drug intervention. The results were impressive with a 73 percent relative reduction in the rate of coronary events after 27 months of follow-up [ 16 ]. Fresh cheeses like Feta and Ricotta are preferred over aged cheeses, which are higher in fats and cholesterol. Mediterranean alpha-linolenic acid-rich diet in secondary prevention of coronary heart disease. Research data indicate that a ratio of or protects most against the development and growth of mammary cancer. Other benefits extensively researched include the prevention of type 2 diabetes [ 30, 31 ] and metabolic syndrome [ 32 ], cognitive impairment [ 33 — 35 ], and unipolar depression [ 36, 37 ]. From this study emerged clearly, as the populations that had adopted a diet based on the Mediterranean Diet presented a very low rate of cholesterol in the blood and, consequently, a minimum percentage of coronary heart disease.
All of these fat items, as well as other dietary items, illustrate how the empirical description of the traditional Mediterranean diet has become a modern scientific concept [ 27 ]. Figure 8. Resveratrol isolated from Polygonum cuspidatum root prevents tumor growth and metastasis to lung and tumor-induced neovascularization in Lewis lung carcinoma-bearing mice. Nurturing public health nutrition education in India. Moreover, exercise coupled to proper nutrition is able to decrease the blood levels of LDL. The protective role of glutathione as an antioxidant and detoxifying agent has been demonstrated in various clinical studies.
