Can drinking freshly squeezed corn juice and purple potato juice relieve constipation? Rumor: Dietary fiber is destroyed, but this is a bad thing.
It is said that coarse grains are laxative, full and nutritious. They are very friendly to obese and three high patients, and have many health-preserving effects on ordinary people.

In recent years, coarse grain drinks such as corn juice and purple potato drinks, which are called drinkable coarse grains, have gradually been sought after by everyone. So can drinking coarse grain drinks really achieve the effect of health preservation?

The national standard "GB 10789-2007 General Rules for Drinks" defines coarse-grain beverages as beverages made of grain as the main raw material.

But in fact, the reason why coarse grains are healthy lies in their "coarseness". Its greatest nutritional value is its dietary fiber, but it has been excluded from the mainstream staple food because of its bad taste.

Therefore, in order to make the taste of coarse grain drinks more acceptable to everyone, many merchants will work hard on the taste and grind the grains as fine as possible. In many cases, they will process all the nutrients of coarse grains and add some additives such as sugar and sweeteners to improve the taste and taste.

At this time, coarse grains without dietary fiber lose the functions of relaxing bowels, increasing satiety and delaying gastric emptying, while sugar and calories increase.

In the industry standard, coarse grain beverage is defined as "cereal beverage with less total solid content and total dietary fiber content." According to the regulations, every 100g of cereal beverage should contain at least 0. 1g of dietary fiber.

However, every 100 gram of fresh corn contains 2.9 grams of dietary fiber, which further shows that the dietary fiber content of coarse grain drinks is very different from that of coarse grains themselves.

In order to reduce the cost, some vendors don't even put whole grains, but they use essence instead. The cost is low and the fragrance is rich, but the nutritional content is almost zero.

Therefore, eating whole grains as a staple food is more beneficial to health, but we should also pay attention to the consumption. Excessive intake of coarse grains will also affect the absorption of some minerals such as calcium, iron and zinc. The general population will take this as a staple food for a long time, but it will have the risk of malnutrition and increase the digestive burden.

Especially for the elderly, children and other people with relatively low gastrointestinal function, it is necessary to control the intake and avoid gastrointestinal discomfort.

Dietary Guidelines for China Residents suggest that normal adults should consume 250-400g of cereals and potatoes every day, including 50- 150g of whole grains and miscellaneous beans. Therefore, it is suggested to replace the staple food with coarse grains, or to add coarse grains to the normal staple food. Don't be superstitious that coarse grain products can play the same role as coarse grains.

Finally, for diabetics, coarse grains are good for controlling blood sugar, but the more finely processed, the softer and more sticky the cooked, and the faster the blood sugar rises after eating. It is recommended to eat coarse grains carefully.
