The minimum nutrient nutrition of fruits and vegetables is less

Nowadays, the nutrients in vegetables and fruits are not as good as before, and human health is also affected.

A cracked agricultural product usually contains more “dry matter”, which accumulates the mineral components that are concentrated together, the so-called “substitution effect”.

Relatively speaking, when growing fruits and vegetables, smaller individuals tend to contain more nutrients.

These minerals include magnesium, iron, calcium, zinc, and the like.

  Reason one: One big “dry matter” is now in the United States, and some people even feel that the taste of vegetables and fruits is not as good as that of grandparents, and the nutrition contained in vegetables and fruits is actually reduced.

The study found that the mineral content of modern fruits and vegetables decreased by an average of 5% to 40% compared to similar crops harvested 50 years ago.

  Relative to the vegetables of a few decades ago, the vegetables produced in modern agriculture are often small in size. If you think that it means more nutrients, it is wrong.

  A cracked agricultural product usually contains more “dry matter”, which accumulates the mineral components that are concentrated together, the so-called “substitution effect”.

Relatively speaking, when growing fruits and vegetables, smaller individuals tend to contain more nutrients.

  In 1981, agronomist W.

M.

Jarrell and R.

B.

Beverly published a research report and mentioned this first.

After the publication of the paper, the academic community has cited this view for more than 180 times.

“It is obvious that this view has been widely recognized.

“Cause 2: Blind pursuit of crops In addition, the pursuit of crops by modern agricultural production methods also has an adverse impact on crop nutrition, mainly reflected in the restrictions on malnutrition.

Between 1996 and 1997, in order to increase the yield of broccoli, South Carolina only selected a single variety with high yields, resulting in a decrease in the protein, amino acid and a large amount of six minerals in the whole broccoli.

  Since nearly 90% of the “dry matter” is a mixture, “the selection of high-yield vegetable varieties for planting actually increases the impurities in the product, but does not guarantee that many other nutrients and various plant chemicals can pass through the yield.The proportion of increase increases accordingly.

Reason 3: Industrial production is detrimental to nutrition. Industrial production also affects the nutrient content of crops.

In the process of crop planting, people are increasingly using fertilizers and pesticides, making modern crops faster than ever before.

However, “early maturity” means that crops do not have enough time to absorb nutrients from the environment such as soil, and the “potassium” of NPK fertilizers often hinders crops from absorbing nutrients.

  Nowadays, organic food is being favored by more and more people.

Davis’s research proves the value of organic food from another perspective.

It is reported that more than 3 billion people worldwide are more or less deprived of nutrients.

At the same time, the surplus areas remaining in the world are blindly pursuing crop yields, resulting in a tedious reduction in nutrients.

However, with the vegetable index, fruit is less affected by genetic and environmental “substitution effects”.

  To supplement enough nutrients, increase the amount of fruits and vegetables. “Now the nutritional content of fruits and vegetables is indeed lower than before, we do not hinder the increase of some consumption.

“I used to eat a tomato to absorb the vitamins. Now I have to eat a kiwifruit at the same time to replenish it; the original chlorophyll, calcium, minerals and other nutrients contained in a pound of vegetables may now need a pound or even two pounds to make up.。  In addition, when choosing fruits and vegetables, don’t buy maturity.

“If a fruit is half a month away from maturity, but looks good, it is likely to use a ripener.

Naturally cooked fruits can mainly smell fruity on the epidermis. The ripened fruits are not even fruity, and even have odors. Some ripened fruits always have a fermented taste.
