How to eat pineapple healthily?
Pineapple tastes a bit "biting", and some people will have allergic phenomena such as oral ulcers. This is because pineapple is rich in protease, which may irritate oral mucosa. Therefore, before eating pineapple, you might as well soak it in more than 60% hot salt water (hot water can also help eliminate protease), which can eliminate some protease and relieve numbness. Pay attention to the soaking time of 5? 10 minutes, otherwise the effect will not be achieved, but it is not advisable to soak for a long time to avoid breeding bacteria. Might as well eat early. In addition to soaking pineapple in salt water, white vinegar can also be used, which has a similar effect, and the sour and salty taste of vinegar has the effect of strengthening sweetness and making pineapple sweeter.
It is worth noting that the protease of pineapple can decompose protein, so a small amount of pineapple can stimulate appetite. People with gastrointestinal diseases, remember not to overdo it.
Regarding the time to eat pineapple, from the nutritional point of view, people with healthy stomach can eat fruit before and after meals (it is recommended to eat fruit after meals for those with bad stomach), and it is recommended to eat fruit in moderation half an hour before meals and 1 hour after meals. People who need to control their weight, blood pressure and blood lipids, eat some fruit half an hour before meals, which can reduce the amount of food they eat at dinner. On the other hand, people who are thin and malnourished have a bad appetite. If you eat a lot of fruit before meals, it may affect your appetite for dinner, which is not conducive to nutrient absorption.
