In our previous cognition, we all know that eating breakfast is a more correct way of health preservation, and many experts have listed a lot of benefits about eating breakfast, do you know? Recently, the professor of Cambridge University in the UK publicly said that eating breakfast is actually harmful to health, what's the matter?
Recently, according to the website of spectator, Terence Kealey, a professor of clinical biochemistry, described in his new book breakfast is a dangerous meal that eating breakfast is harmful to health, causing heated discussions in the health and medical circles. Although this view is astonishing and contrary to common sense, the speaker is a full authority. As you can see from Professor Kealey's resume, Terence Kealey graduated from Harvard, once a professor in Cambridge, and now is the vice president of Buckingham University. Therefore, many friends have been involved in the social media craze without judging the truth of their opinions, and have forwarded comments that "breakfast is dangerous". Let's calm down and see if it's more dangerous to eat breakfast or not?
The surge and stability of blood sugar can not be seen only in numerical value
To understand the idea that breakfast is dangerous, we still need to go back to the original. Professor Kealey found the danger of breakfast an accident. He himself is a diabetic. In the process of measuring blood sugar with a home blood glucose meter, he found a phenomenon - "blood sugar soars after breakfast, and blood sugar is stable before and after lunch and dinner" (if you have a real friend, here is also the corresponding original text: anywhere can buy inexpensive blood glucose testing kits at their local chemist, and when I tested my bl ood glucose levels I discovered they rose alarmingly after breakfast but only modestly after other meals。 )
However, people with a little knowledge of blood sugar may not help but have some questions about the 'surge' and 'stability' in the article. First of all, what's his blood glucose index before and after eating? Is it 4 before breakfast, 7 after eating, or 10 before lunch, and 11 after eating? We need to know that these two situations are not so simple as numerical growth. The former looks like 'soaring', but it's actually a normal phenomenon for normal people; the latter looks like 'stable', but it's instead Abnormal phenomena. Because the index of fasting blood glucose before meals is normal from 3.9 to 6.2, while the index of postprandial blood glucose within an hour is normal from 9, but if it is already 10 before meals, it is abnormal whether there is a surge after meals or not.
After we understand this, we can directly question professor Kealey. Eating on an empty stomach in the morning will cause blood sugar to look 'soaring', but if you eat lunch without breakfast, you will still be on an empty stomach when you eat lunch. Doesn't that lead to the same so-called 'soaring' effect? And so on, in order to avoid 'soaring', can't you eat dinner?
Eating less and eating more is a healthier way to eat
President Kealey also has a point that many people don't feel hungry in the morning, so why eat? Isn't that to be hungry in the mornings, 'every experimental study shows that breakfast only adds to the total scales a person consumes. It has to be said that there is no nutritional common sense in this view. As anyone who has read the dietary guide knows, whether it is the Chinese version or the American version, there should be a certain number of calories consumed every day. According to the individual differences in age, gender, type of work, etc., you can find the corresponding values in the comparison table of the dietary guide.
For example, for an adult Chinese man with moderate physical labor, the recommended daily intake in the Chinese dietary guidelines is 2200 kcal. And these two thousand calories are a one-time intake when you feel hungry? Of course, they should be distributed in three meals separately, and eating less and eating more is a healthier way of eating. Of course, if you have a special purpose, you can also reduce one meal. It is said that Japanese sumo wrestlers don't eat breakfast in order to gain weight and eat the calories twice a day.
It's really dangerous not to eat breakfast
Breakfast is special because the body just woke up from a deep sleep when eating breakfast. When it needs to be supplemented, if it is not supplemented in time or not, it is easy to affect the health of the body.
For example, if you don't eat breakfast for a long time, it is easy to have gallstones. The imbalance between cholesterol and cholic acid is one of the causes of gallstones. After a night's sleep, the body has accumulated a lot of cholesterol. It's just when it needs cholic acid, and eating breakfast just can promote the secretion of cholic acid. The longer the fasting time is, the less the bile acid is secreted, the higher the cholesterol ratio is, until the precipitated crystals form and attach to the gallbladder, which becomes gallstones. So, we can get a formula: 8 hours sleep + no breakfast = 12 hours Fasting & asymp; Gallstone catalyst.
In addition, not eating breakfast will lead to hypoglycemia, and everyone knows that hypoglycemia will lead to dizziness, which is why some students will faint if they run without breakfast. This is because the blood glucose concentration is the premise to ensure the normal operation of brain tissue. When the blood glucose concentration is low, the brain's response is hunger at the beginning, and if it is not supplemented, it will lead to inattention, slow response and even hallucination. So in order to have a better working and learning state, breakfast is still to eat.
If we really need to pay attention to what we eat breakfast, it is also a nutritional match. It is often said that "breakfast is to eat like an emperor", but don't misunderstand this sentence, thinking that big fish and big meat is the right way to open breakfast. Breakfast should be rich and abstemious. Specifically, it can be designed according to our dietary guidelines, so that the nutritious and dynamic breakfast becomes the first expectation after opening your eyes every day.
As for Professor Kealey's "new discovery" about breakfast sharing, it has not been verified by scientific methods. It is not rigorous. Let's listen to it, but don't take it to heart.
