Nowadays, many restaurants or residents always emphasize taste and only talk about food without nutrition. In order to taste good, many people put more oil and sugar in cooking, or fry or fry food in oil. At present, the average intake of oil per person in China is 40 grams per day, but the "China Residents' Balanced Diet Pagoda" issued by China stipulates that the intake of oil per person per day should not exceed 25 grams. Excessive intake of oil and sugar will lead to chronic diseases such as obesity and hypertension.
It is understood that many residents in our country directly use five-liter oil drums to pour oil into the pot, which is often excessive when pouring; In order to improve the taste of dishes, many restaurants and canteens also put more oil and sugar. After eating vegetables, they often find oil at the bottom of the plate.
Excessive salt intake is also a problem faced by China people at present. The standard issued by the World Health Organization is that the salt intake per person per day should not exceed 6 grams, and the standard issued by the Nutrition Society of China is that the salt intake per person per day should not exceed 10 grams. However, at present, the daily salt intake per person in China reaches15 ~ 20g, far exceeding these two standards. Excessive salt intake will directly lead to chronic diseases such as hypertension.
2. Meat consumption in the diet has soared.
More than 30 years ago, people's living standards were not high. The food of the public is mainly coarse grains and vegetarian dishes. Only on holidays can they improve their lives with tickets. In fact, they bought some meat dishes. More than 20 years ago, people's living standards began to improve. Although vegetarianism is still the main thing, they can eat a meat dish every other day or two. Now you don't have to worry about eating and drinking, and meat dishes account for 70% to 80% of the table. Losing weight has become a fashionable topic.
The proportion of meat in residents' diet is at least twice that of 20 years ago. Meat is a high-energy and high-fat food. Excessive intake often leads to obesity, which is the inducing factor of some chronic diseases.
Eat fried food because it tastes delicious.
Despite many storms, many people's enthusiasm for foreign fast food remains undiminished. In several fast food restaurants in Renmin Middle Road, Guangzhou, people are always crowded, and fried food such as French fries is still the main food consumed by customers. In the evening, the street barbecue stalls along Huifu West Road and Jinlong East Road are also very prosperous, and barbecue foods such as mutton skewers and grilled squid are also very popular among passers-by.
Many people know that fried food is unhealthy, but they still think it is not delicious. After high temperature or smoking, fried food such as fried dough sticks and twisted dough sticks, baked food such as kebabs, smoked fish and bacon will contain many carcinogens, among which benzopyrene is the most representative carcinogen. Benzopyrene is a strong carcinogen, which can cause tumors in any part of the human body and is very toxic. Benzopyrene can also invade the fetus through the placenta, the baby through the milk, and also cause cardiovascular and cerebrovascular diseases.
4. The nutritional intake of three meals a day is not balanced
Pay attention to the rationality of the distribution of three meals a day in a balanced diet. Generally, the energy of breakfast, lunch and dinner accounts for 30%, 40% and 30% of the total energy respectively. But the current situation is that many people eat too little or not for breakfast, but eat too much for dinner. Where does the morning energy come from without breakfast? Eating too much at night is not only easy to get fat, but also affects sleep.
A small amount of drinking is better than no drinking, and no drinking is better than drinking. According to the standard of moderate drinking for adults, the alcohol intake of each person should be 12 ~ 20g/ day, and it should not exceed 1 if calculated by 40% liquor.
Food intake and physical activity should also be balanced. If you eat too much and don't exercise enough, excess energy will accumulate in the body in the form of fat, increase your weight and get fat over time. Therefore, mental workers and people with less activity should strengthen exercise and carry out appropriate activities, such as brisk walking, jogging and swimming.
