However, a recent study overturned this point. A new study published in the Proceedings of the National Academy of Sciences shows a closely related phenomenon through the different intake of staple food and the death probability corresponding to different ages.
On the contrary, for people over 50 years old, adding staple food in moderation can greatly reduce the mortality rate.
Other studies have found that after the age of 50, the body's metabolism and various physiological functions such as tissues and organs are slowly declining. If you adopt a high-carbohydrate diet with low-fat food, it will be beneficial to prolong life.
The "ketogenic diet" that everyone was encouraged to adopt a few years ago is also beneficial to the health of middle-aged and elderly people. The ketogenic diet mentioned here is mainly the practice of protein with low calorie, low carbohydrate and high fat.
It can be seen that every study has its own rhetoric. Do you want to eat too many carbohydrates, especially staple food?
Judging from the energy supply ratio of people's daily intake of carbohydrates, it accounts for 55~65% of the whole day, and staple food is the main source of carbohydrates in various foods. Maybe many people think that eating staple food is bad for our health, but more importantly, we need to learn how to eat staple food.
Here are some principles to teach you to eat staple food:
Eat staple food, not just polished rice noodles;
Nowadays, rice, steamed bread and noodles are the most important foods on the table of every household. These foods are delicious, but they also have the problems of high calories and low nutritional density. Therefore, in order to ensure the nutrition of staple food and reduce calorie intake, we should not only eat refined rice flour, but also add rich grains and potatoes on the basis of refined rice flour.
As mentioned in the food exchange law, with the same energy of 90 kilocalories, we can eat 25g of potatoes and 25g of beans, which is more balanced in nutrition.
Eat staple food, fist size:
When asked how much staple food to eat per meal, many people may be confused about this question and even eat as much as they want, but this is actually wrong. No matter whether adults are fat or thin, the standard amount of staple food for each meal should be the size of a fist, neither too much nor too little.
Eat staple food instead of "fake staple food";
Such as cereal biscuit, bread, puffed cereal, etc. They are all delicious, but they not only lose a lot of nutrients after processing, but also easily produce harmful ingredients, such as benzopyrene and aromatic compounds.
