Whole grains are nutritious, high in dietary fiber, filling, and cause a slow rise in blood sugar, which is very helpful in preventing and controlling high blood pressure, high blood sugar, and high cholesterol, as well as avoiding obesity, cardiovascular diseases, and even cancer. However, there are two groups of people who should not eat too many whole grains.
The first group is people with poor gastrointestinal function. They should not eat too many whole grains.
The dietary fiber in whole grains helps people with the "three highs" control their blood sugar and blood lipids and prevent obesity. However, too much fiber can also be a burden on people with poor gastrointestinal function. Especially for those who already have stomach ulcers or poor gastric motility, eating a little too much coarse grains can easily cause bloating, stomach pain, and various other discomforts. Therefore, people with relatively poor digestion, especially some weak middle-aged and elderly people and children, are not suitable for eating excessive coarse grains.
The second group is women who are dieting or are vegetarians. They should not eat too many coarse grains.
Coarse grains are high in dietary fiber, low in calories, and more filling, which is helpful for weight loss. However, some women, whose weight is not overweight or even on the low side, insist on losing weight in an improper way. They often lose weight by eating a lot of vegetables, a small amount of coarse grains instead of staple foods, and basically not eating fish, meat, eggs, milk, or soy products. This can easily lead to malnutrition, irregular menstruation, and other issues. Therefore, it is not recommended that people with poor nutritional status, insufficient nutrients like calcium, iron, and protein, or those with unreasonable vegetarian diets eat too many coarse grains.
A balanced diet rich in protein, high-quality fats, and trace elements, combined with coarse grains, is more suitable for these groups of people.
