Don't eat sour fruit on an empty stomach?
Can't generalize!
Whether you can eat sour fruit on an empty stomach cannot be generalized. For example, apple is a kind of fruit with more acid, but some people eat an apple when they are hungry, which not only won't feel gastrointestinal discomfort, but also reduce energy intake and play a role in losing weight to some extent. However, after eating apples on an empty stomach, people with bad stomachs will react with stomach acid to form precipitates because of some components in the fruit, such as tannins, and then cause some discomfort. For example, pomegranate and tomato all contain some ingredients that stimulate gastric acid secretion or react with gastric acid to form precipitation. For friends who have a bad stomach, we suggest that you try to avoid eating sour fruits on an empty stomach.
In order to ensure nutrient absorption, we should eat fruit before eating?
I can't believe it!
There is a saying circulating on the Internet: "Eat first and then eat fruit. The fruit is blocked by dinner and cannot be digested directly. But the fruit itself is more perishable than dinner. When it is the turn of the fruit to digest, the nutrients are lost and deteriorated, and the rest are dregs. " This statement that sounds quite "image" is incorrect. If you can't eat fruit on an empty stomach or after meals, when should you eat fruit? Obviously, there is a logical problem.
Further discussion, what is the conflict between eating and eating fruit? If there is, it is because the stomach capacity is limited. One eats too much, and the other can't eat any more. The main component of fruit is water, followed by a small amount of carbohydrates, protein, fat and a small amount of water-soluble vitamins and minerals. The digestion and absorption of these nutrients are not directly related to eating dinner.
For some special people, such as diabetics, it is recommended to eat a small amount of fruits with low GI (glycemic index) between meals. On the one hand, a small amount of dietary fiber in fruits helps to delay the digestion and absorption of carbohydrates in staple foods. On the other hand, timely and appropriate amount of fruit after meals is also very important for the nutritional balance of diabetics.
Is there too much pesticide residue in fruit skin to eat?
Don't worry!
Everyone must have heard a tongue twister: "Eat grapes without spitting their skins". Is the fruit with skin edible? Many people choose not to eat because they are worried about pesticide residues. In fact, for water-soluble pesticides, after careful cleaning, substances harmful to human health will not remain on fruits. Recently, the Ministry of Agriculture and Rural Affairs, together with the National Health and Wellness Commission and the General Administration of Market Supervision, issued a new version of the Maximum Residue Limits of Pesticides in Food, which also stipulated the dosage of pesticide residues more strictly from the legal and regulatory level, so you don't have to worry too much about the problem of pesticide residues.
From the point of view of nutrition, the peel of fruit usually contains more substances beneficial to health than the pulp, such as dietary fiber and phytochemicals. Therefore, it is suggested that the edible skin of fruit can be eaten under the premise of cleaning.
How much fruit is the most suitable?
Half a catty a day. Are you up to standard?
There are also many misunderstandings about how much fruit should be eaten. Some friends who need to lose weight think that eating more fruits is better, which can reduce the intake of staple food and help to lose weight. First of all, replacing some staple foods with fruits is indeed beneficial to energy control, but not the more the better. As we mentioned earlier, the nutrients in fruits are mainly water and a small amount of carbohydrates. Eating fruit for a long time will lead to insufficient intake of some nutrients such as protein, vitamin A and vitamin B, which is not conducive to health.
Some friends think that fruit has a high sugar content, and eating fruit without eating it will make you fat. People who have this kind of cognition confuse the relationship between sweetness and obesity, and think that sweetness is high energy, which will make them fat. In fact, fruit with the same weight has much lower energy than staple food. So don't worry about eating fruit and getting fat.
It should be noted that the Dietary Guide for China residents points out that the recommended fruit intake of China residents is 200 ~ 350g (about half a catty) per day, but the average fruit intake of China residents is far from this standard. It is also suggested to increase the intake of fruit in daily life to meet the body's demand for a balanced diet.
Out-of-season fruit is unhealthy?
Diversity should be maintained!
With the improvement of living standards, the choice of fruits is really wider and wider. No matter what season, as long as you are willing to spend money, any fruit can be bought home and tasted at any time. Especially when many old people buy fruits for their grandchildren, they are willing to spend a lot of money to buy out-of-season fruits. Many people don't agree with this on the grounds that out-of-season fruits are unhealthy.
We suggest that consumers should focus on seasonal and local fruits when buying fruits, and at the same time, they need to maintain the diversity of fruit types. It is inaccurate to think that there will always be unhealthy factors in the planting process of out-of-season fruits.
Whether there are unhealthy factors in fruits and vegetables is not necessarily related to natural cultivation or greenhouse cultivation. With the popularization and application of modern agricultural technology, greenhouse fruit planting technology is becoming more and more mature. All preservatives, food additives and plant growth regulators are harmless to human health as long as they meet the relevant national standards and are used within the prescribed dosage.
