Dieta Mediterránea Pdf

[Badomero Schoulund]

Dietis known to have an effect on long-term diseases. These include heart and blood vessel problems known as cardiovascular disease. Observations from a study in the 1960s found that cardiovascular disease was linked to fewer deaths in some Mediterranean countries, such as Greece and Italy, than in the U.S. and northern Europe.

Olive oil and nuts are the main sources of fat in the Mediterranean diet. They provide unsaturated fat. When unsaturated fat comes from plant sources, it seems to lower levels of total cholesterol as well as low-density lipoprotein, also called LDL or "bad" cholesterol.

Omega-3s are unsaturated fats that may lower immune system action in the body known as inflammation. They also may help reduce blood fats called triglycerides, and they affect blood clotting. Omega 3s may lower the risk of stroke and heart failure too.

Red wine tends to be included more often than is white wine. Some experts and dietary guidelines recommend that women limit themselves to one glass of wine a day, and for men no more than two glasses a day.

Factors that affect your decision might be the extra calories alcohol brings to the diet, or any kidney or liver problems you may have. And if you just don't like the taste of alcohol, that's a good reason to stay away from it too.

Chances are you have heard of the Mediterranean diet. If you have a chronic condition like heart disease or high blood pressure, your doctor may even have prescribed it to you. It is often promoted to decrease the risk of heart disease, depression, and dementia.

The Mediterranean diet is a primarily plant-based eating plan that includes daily intake of whole grains, olive oil, fruits, vegetables, beans and other legumes, nuts, herbs, and spices. Other foods like animal proteins are eaten in smaller quantities, with the preferred animal protein being fish and seafood. Although the pyramid shape suggests the proportion of foods to eat (e.g., eat more fruits and vegetables and less dairy foods), it does not specify portion sizes or specific amounts. It is up to the individual to decide exactly how much food to eat at each meal, as this will vary by physical activity and body size. There are additional points that make this eating plan unique:

This sample meal plan is roughly 2000 calories, the recommended intake for an average person. If you have higher calorie needs, you may add an additional snack or two; if you have lower calorie needs, you may remove a snack. If you have more specific nutritional needs or would like assistance in creating additional meal plans, consult with a registered dietitian.

Research has consistently shown that the Mediterranean diet is effective in reducing the risk of cardiovascular diseases and overall mortality. [3, 4] A study of nearly 26,000 women found that those who followed this type of diet had 25% less risk of developing cardiovascular disease over the course of 12 years. [5] The study examined a range of underlying mechanisms that might account for this reduction, and found that changes in inflammation, blood sugar, and body mass index were the biggest drivers. Similar benefits were found in a meta-analysis of 16 prospective cohort studies following more than 22,000 women for a median of 12.5 years. [6] Those who had the highest adherence to a Mediterranean diet showed a 24% lower risk of cardiovascular disease and 23% lower risk of premature death compared with those who had the lowest adherence.

One interesting finding of this eating plan is that it dispels the myth that people with or at risk for heart disease must eat a low fat diet. Although it does matter which types of fats are chosen, the percentage of calories from fat is less of an issue. The PREDIMED study, a primary prevention trial including thousands of people with diabetes or other risk factors for heart disease found that a Mediterranean diet supplemented with extra virgin olive oil or nuts and without any fat and calorie restrictions reduced the rates of death from stroke by roughly 30%. [7] Most dietary fats were healthy fats, such as those from fatty fish, olive oil, and nuts, but total fat intake was generous at 39-42% of total daily calories, much higher than the 20-35% fat guideline as stated by the Institute of Medicine. [8] Risk of type 2 diabetes was also reduced in the PREDIMED trial. [9]

Research supports the use of the Mediterranean diet as a healthy eating pattern for the prevention of cardiovascular diseases, increasing lifespan, and healthy aging. When used in conjunction with caloric restriction, the diet may also support healthy weight loss.

Methods: In a multicenter trial in Spain, we assigned 7447 participants (55 to 80 years of age, 57% women) who were at high cardiovascular risk, but with no cardiovascular disease at enrollment, to one of three diets: a Mediterranean diet supplemented with extra-virgin olive oil, a Mediterranean diet supplemented with mixed nuts, or a control diet (advice to reduce dietary fat). Participants received quarterly educational sessions and, depending on group assignment, free provision of extra-virgin olive oil, mixed nuts, or small nonfood gifts. The primary end point was a major cardiovascular event (myocardial infarction, stroke, or death from cardiovascular causes). After a median follow-up of 4.8 years, the trial was stopped on the basis of a prespecified interim analysis. In 2013, we reported the results for the primary end point in the Journal. We subsequently identified protocol deviations, including enrollment of household members without randomization, assignment to a study group without randomization of some participants at 1 of 11 study sites, and apparent inconsistent use of randomization tables at another site. We have withdrawn our previously published report and now report revised effect estimates based on analyses that do not rely exclusively on the assumption that all the participants were randomly assigned.

Results: A primary end-point event occurred in 288 participants; there were 96 events in the group assigned to a Mediterranean diet with extra-virgin olive oil (3.8%), 83 in the group assigned to a Mediterranean diet with nuts (3.4%), and 109 in the control group (4.4%). In the intention-to-treat analysis including all the participants and adjusting for baseline characteristics and propensity scores, the hazard ratio was 0.69 (95% confidence interval [CI], 0.53 to 0.91) for a Mediterranean diet with extra-virgin olive oil and 0.72 (95% CI, 0.54 to 0.95) for a Mediterranean diet with nuts, as compared with the control diet. Results were similar after the omission of 1588 participants whose study-group assignments were known or suspected to have departed from the protocol.

Conclusions: In this study involving persons at high cardiovascular risk, the incidence of major cardiovascular events was lower among those assigned to a Mediterranean diet supplemented with extra-virgin olive oil or nuts than among those assigned to a reduced-fat diet.

The Mediterranean diet is a diet inspired by the eating habits and traditional food typical of southern Spain, southern Italy, and Crete, and formulated in the early 1960s.[1] It is distinct from Mediterranean cuisine, which covers the actual cuisines of the Mediterranean countries, and from the Atlantic diet of northwestern Spain and Portugal. While inspired by a specific time and place, the "Mediterranean diet" was later refined based on the results of multiple scientific studies.[2]

This approach emphasizes a plant-based diet, focusing on unprocessed cereals, legumes, vegetables, and fruits.[3][4] It also includes moderate consumption of fish, dairy products (mostly cheese and yogurt), and a low amount of red meat.[3][5] Olive oil has been studied as a potential health factor for reducing all-cause mortality and the risk of chronic diseases.[6]

As a nutritional recommendation, the Mediterranean diet is different from the cultural practices identified by UNESCO in 2010 under the heading "Mediterranean diet" on the Representative List of the Intangible Cultural Heritage of Humanity, which defined the diet as "a set of skills, knowledge, rituals, symbols and traditions concerning crops, harvesting, fishing, animal husbandry, conservation, processing, cooking, and particularly the sharing and consumption of food".[12][13]

The Mediterranean diet is included among dietary patterns that may reduce the risk of cardiovascular diseases.[10] A 2013 Cochrane review found limited evidence that a Mediterranean diet favorably affects cardiovascular risk factors.[16] A 2013 meta-analysis compared Mediterranean, vegan, vegetarian, low-glycemic index, low-carbohydrate, high-fiber, and high-protein diets with control diets. The research concluded that Mediterranean, low-carbohydrate, low-glycemic index, and high-protein diets are effective in improving markers of risk for cardiovascular disease and diabetes, while there was limited evidence for an effect of vegetarian diets on glycemic control and lipid levels unrelated to weight loss.[18] However, more cautious reviews arose in early 2016, raising concerns about the quality of previous systematic reviews examining the impact of a Mediterranean diet on cardiovascular risk factors.[19] These reviews insisted upon the need for further standardized research,[20] stating that the evidence for possible prevention of cardiovascular disease by the diet was "limited and highly variable".[21] Reviews in 2016-17 reached similar conclusions about the ability of a Mediterranean diet to improve cardiovascular risk factors, such as lowering the risk for hypertension and other cardiovascular diseases.[9][22] A Mediterranean diet is recommended as a means of lowering Apolipoprotein B.[23]
