Diet is influenced by personal preferences, family, geographical environment and traditional culture, and forms different eating habits, which accompany people's life. People have two different views: eating is healthy, eating is sick, and diet can both support and harm people. Therefore, the diet should be "four essentials": first, "five flavors are harmonious", fast food should not be partial to food, and it should be reasonably matched and nutritious. Second, we should be "moderate", that is, we should not be too full or too hungry, and we should eat moderately. Third, we should pay attention to food hygiene to prevent diseases from entering the mouth. Fourth, it should be different from time to time, from people to places.
"China Residents' Balanced Diet Pagoda (20 16)" clearly tells us what to eat for three meals a day and how much to eat, and also explains the above "four essentials" very clearly. Cereals are at the bottom, and each person should eat 250-400 grams a day; Grain is the sum of flour, rice, corn flour, wheat and sorghum. Vegetables and fruits occupy the second floor and should be eaten 300-500 grams and 200-400 grams every day; Vegetables and fruits are often put together because they have a lot of sex. Animal foods such as fish, poultry, meat and eggs are located on the third floor. You should eat 125-225g (50- 100g of fish and shrimp, 50-75g of livestock and poultry meat and 25-50g of eggs) every day. Milk and beans occupy the fourth floor. You should eat 300 grams of milk and dairy products, 50 grams of beans and bean products every day. Cooking oil does not exceed 25 grams or 30 grams per day, and salt does not exceed 6 grams. It is suggested that adults with mild climate and light physical activity should drink at least 1200ml (about 6 cups) of water every day. It is suggested that adults should take more than 6,000 steps of physical activity every day, and if physical conditions permit, it is best to take 30 minutes of moderate-intensity exercise.
As early as 2400 years ago, Huangdi Neijing emphasized that the diet must be rich and varied in order to absorb various nutrients. "On Su Wen's dirty qi method" says: "Five grains are the supplement, five fruits are the help, five animals are the benefit, five dishes are the supplement, and the smells are combined to supplement the essence." So what to eat and how to eat, our ancestors have already summed it up for us. However, the accelerated pace of people's life and the impact of modern life did not pay attention to the precious wealth left by ancient people, so that under the impact of various viewpoints, they were at a loss about how to eat and what to eat.
I want five flavors. Five flavors refer to the five flavors of diet, namely sour, bitter, sweet, pungent and salty. The five flavors reflect the real taste of food, can nourish the viscera and are the material basis of human life activities. Chinese medicine theory says that acid enters the liver, bitter enters the heart, sweet enters the spleen, pungent enters the lung and salty enters the kidney. "Compendium of Materia Medica" records that "the sour can be astringent, the bitter can be diarrhea, dryness and firmness, the sweet can be soothing, the pungent can be moistening, the salty can be soft and firm, and the weak can benefit from leakage. These five flavors are also useful. " To sum up, pungent, sour, sweet, bitter, salty and soft. Taste preference based on five elements will harm related organs. Huangdi Neijing: Nutong Tianli pointed out: "The taste is too sour, the liver qi produces fluid, and the temper is absolutely;" The taste is too salty, the bones are exhausted, the muscles are short and the heart is depressed; The taste is too sweet, the heart is full of asthma, the color is black, and the kidney is unbalanced; The taste is too bitter, the temper is not strong, and the stomach is strong; The taste is too spicy, relaxing muscles and activating collaterals, and the spiritual center. "For people with diseases, the taboo of taste is very important." Su Wen? "Xuan Ming's Five Qi Theory" said: "Qi, qi disease does not eat too much pungent; Blood is salty, and blood diseases do not eat salty; Bitter bones, bone diseases are not much; If you are willing to eat meat, you won't eat too much when you are sick; Sour gluten, gluten disease does not eat more acid ",it can be seen that the five flavors of diet must be harmonious."
Huangdi's Neijing Su Wen Tian Rage said: "Sincere with five flavors, healthy and tender bones, qi and blood running, dense management." If so, then the bones are fine, the Tao is like the law, and there is a destiny. " In other words, the five flavors are properly blended, making the bones erect, the tendons soft, the blood circulation, the muscles elastic and the skin firm. In this way, you will have a strong backbone. If you follow this rule strictly enough, you can enjoy your life.
