The ubiquitous sugar.
In the past, when productivity was not so developed, sugar used to be a luxury, and it could only be eaten on some special occasions and at some time. However, today, the production of sugar is no longer restricted, and there is even a trend of flooding. In recent years, sugar has become an important part of our daily diet (especially in various snacks), and the proportion seems to be rising.
Most people live on white rice and flour, and many people like to eat vegetables with high starch content, such as potatoes, sweet potatoes and taro. These foods are mainly composed of glucose and have a high glycemic index.
Added sugar is everywhere. Yogurt, juice and cereal, once considered as healthy foods, can't stand a closer look: in order to improve the taste and increase the attractiveness, a lot of sugar is added to these foods, and even the juice without extra sugar has an amazing sugar content, because the original cellulose in the fruit is removed from the pure juice. Other popular "junk food", such as puffed snacks, cola, ice cream, fried food, etc. A lot of sugar is often added in the seasoning process.
Studies on animals and humans show that a large intake of carbohydrates will greatly increase the risk of obesity, diabetes and cardiovascular diseases. A study on obese women in the United States shows that a large amount of sugar intake in the diet is related to the emergence of insulin resistance and the increased risk of stomach and esophageal related diseases; A study on 20 17 suggested that a large intake of sugar would shorten human gene telomeres, which might shorten human life span.
A high-carbon water diet will bring insulin resistance.
High-carbon and high-moisture foods can cause violent fluctuations in blood sugar, which makes the pancreas have to "work overtime". The body is in a state of secreting a large amount of insulin for a long time, which easily leads to the insensitivity of cells in the body to insulin, that is, insulin resistance, which keeps blood sugar high and even leads to diabetes.
Insulin is an important hormone in sugar metabolism, because only with the help of insulin can the sugar in blood smoothly enter every cell and become the energy source of cells. Insulin resistance will hinder this process, making cells unable to eat sugar and weak due to lack of energy. Insulin resistance also means that the body is in an inflammatory state. Therefore, many people who don't leave white rice, white flour and sugary drinks every day often feel tired, sleepy and irritable; Those who have allergic symptoms are also prone to allergic attacks after eating a lot of sugar. Many people are eager to decompress through sugary foods such as desserts when they are stressed and depressed, which is also related to the special role of sugar in the human body.
Many people think that only obese people are at risk of insulin resistance and hyperglycemia. However, obesity and insulin resistance are not absolutely related. Some people look fat, but their metabolism is completely normal. Some people look thin, but in fact, they have accumulated a lot of fat in their internal organs, severe insulin resistance and even diabetes. There are not a few people with fatty liver among thin people. Subcutaneous fat is visible, so it is often taken seriously; Fat accumulated around internal organs is not easy to be detected, but it is more likely to cause diseases after long-term neglect.
Insulin resistance leads to endocrine disorders.
Insulin resistance is not a patent for diabetics. Polycystic ovary syndrome (PCOS) is a disease related to female endocrine, usually accompanied by insulin resistance. 50-75% patients with polycystic ovary syndrome have different degrees of insulin resistance, and the risk of developing type II diabetes is 5- 10 times that of normal women.
A study of 20 15 shows that the incidence of breast cancer in women with insulin resistance is basically twice that of normal people. That is to say, whether you are obese or not, if you have insulin resistance in your body, your risk of breast cancer is 1 times, and the correlation between insulin resistance and breast cancer is obvious.
Once insulin resistance occurs in the body, the free estrogen in the body will increase, and these abnormally increased hormones will cause various disorders of the reproductive system. Unexplained symptoms such as hyperplasia of mammary glands, infertility and hysteromyoma may all be related to endocrine disorders caused by insulin secretion.
Don't let the high-carbon water diet disturb the hormone balance again.
In 2004, a group of scientists made a large-scale comparative experiment with Mexico 1500 women as samples. It was found that women whose refined carbohydrates accounted for 62% or more of the total calories in their daily diet were 2.22 times more likely to develop breast cancer than other women.
The main foods of these women who are keen on extracting carbohydrates are corn starch round cakes, drinks and white bread, which are foods with very little fiber and very high glycemic index. In fact, the traditional staple food of Mexicans is raw corn, which contains more vitamins and cellulose than corn starch and is more beneficial to health. However, with the pace of globalization and the erosion of American diet, more and more Mexican residents give up the traditional diet and turn to refined staple food and sugary drinks with high carbon water, which has a great impact on their health.
At that time, the impact of this study was so great that people began to believe that healthier carbohydrate sources would reduce the risk of breast cancer. Experts and residents in the United States have also begun to pay attention to this. In the following year's Dietary Guidelines for American Residents, experts suggested that at least half of the grains people consume every day should be whole wheat or other coarse grains.
The latest Dietary Guidelines for China Residents in 20 16 also pointed out that the daily intake of cereals and potatoes is 250 ~ 400g, including coarse grains and beans 50 ~150g and potatoes 50 ~100g; The intake of added sugar should be controlled, not more than 50 grams per day, preferably less than 25 grams.
Many people habitually associate many diseases with oil and salt, but ignore the harm of high-carbon water. Excessive carbohydrate intake will not only lead to obesity, but also cause more serious metabolic problems. For women, we should also be alert to the interference of this unreasonable diet on the body's endocrine.
It is best to take oats, buckwheat, whole wheat and other miscellaneous grains as the staple food. When buying processed foods and drinks, we should also pay attention to the amount of sugar added.
Choose your diet more wisely, and you will get healthy.
