The pyramid of healthy eating is based on daily exercise and weight control, because these two factors are very important for people to stay healthy. They will also affect what people eat and how they eat, and how the food people eat affects their health. Looking up from the base of the pyramid of healthy eating, it includes: whole wheat food (in most meals) The human body needs carbohydrates to provide energy, and the best source of carbohydrates is whole wheat, such as oatmeal, coarse bread and brown rice (that is, brown rice). They contain bran and germ, as well as energy-rich starch. It takes longer for the human body to digest whole wheat than to digest direct carbohydrates such as white bread, which will keep the blood sugar and insulin in a reasonable level and will soon drop. Good control of blood sugar and insulin levels can reduce human hunger and prevent the occurrence of type II diabetes. Vegetable oil. Americans get1/3 of the daily calories from fat on average, so it makes sense to put them at the bottom of the pyramid. Note that vegetable oil is specifically mentioned here, not all kinds of fats. Healthy unsaturated fats come from olives, soybeans, corn, sunflowers, peanuts and other vegetable oils, as well as fatty fish such as salmon. These healthy fats not only improve human cholesterol levels, but also effectively prevent potential sudden cardiac death and myocardial infarction. Vegetables (in large quantities) and fruits (2 to 3 times a day). Eating more vegetables and fruits can effectively prevent heart disease and angina pectoris; Prevent all kinds of cancers; Lowering blood pressure; Relieve intestinal diseases called diverticulitis; Prevention and treatment of cataract and glaucoma, these two eye diseases are the main causes of blindness in the elderly over 65 years old. Fish, poultry and eggs (0 to 2 times a day). This is the main source of protein. A large number of studies show that eating fish can reduce the risk of heart disease. Muscle and turkey are low in saturated fat, and they are also good sources of protein. Eggs have been demonized for a long time, because their cholesterol content is relatively high. In fact, eggs are a good breakfast, which is much better than fried doughnuts or flour doughnuts. Nuts and beans with shells (1 to 3 times a day). Nuts and beans with shells are the best sources of plant protein, plant fiber, vitamins and minerals. Beans with shells include black beans, broad beans, edamame and other dry goods. Many nuts are rich in healthy fat. For example, almonds, walnuts, small walnuts, peanuts, hazelnuts and pine nuts can directly indicate that the food is beneficial to the heart. Dairy products and substitute calcium (daily 1 2 times). In order to prevent and treat osteoporosis, calcium and vitamin D are needed, and dairy products are the traditional source of calcium for Americans. Besides foods containing saturated fat such as milk and cheese, there are other healthy ways to get calcium. For example, three cups of whole milk are equivalent to the saturated fat contained in thirteen strips of cooked bacon. If you like dairy products, stick to skim or low-fat products. If you don't like dairy products, substitute calcium food is the guarantee to ensure the daily calcium demand of human body. Red meat and cream (use carefully): These foods are placed at the top of the pyramid of healthy eating because they are rich in saturated fat. If you eat red meat every day, such as beef and mutton, trying fish or chicken several times a week can improve your cholesterol level. Similarly, you can switch from cream to olive oil. Rice, white bread, potatoes, spaghetti, and desserts (with caution): Why are these staple foods of all Americans placed at the top of the pyramid of healthy eating? Because they can cause the rapid increase of blood sugar, lead to weight gain, diabetes, heart disease and other chronic diseases. Whole-wheat carbohydrates stabilize human blood sugar, at least increase slowly without exceeding the normal level of human body, so that human body can handle excess blood sugar. Multivitamins: Daily multivitamins and mineral supplements are the nutritional reserves of human body. The food we eat every day sometimes can't provide all the nutrients the human body needs every day. At this time, multivitamins can fill the nutritional gap for even the most cautious diners. Please choose the genuine multivitamins. Alcohol (moderate): Drinking a little wine every day can reduce the risk of heart disease. Moderate amount is very important, alcohol is a double-edged sword, with both harm and benefit. For men, the balance point is to drink 1 2 cups a day, which does not mean draft beer cups. For women, one glass a day is enough. The pyramid of healthy diet summarizes the best dietary information today. It is not a castle in the air or a static one. With the development of the times and the deepening and diversification of research, the pyramid of healthy diet will reflect the latest and most important research results with the times. Ten Best Diet Matching Methods We should pay attention to matching on the table, and the correct matching can make us get more nutrition.
