CAMP is an important physiologically active substance, which participates in many physiological activities in human body, can regulate immune system, enhance myocardial contractility, protect coronary artery, lower cholesterol and inhibit the proliferation of cancer cells.

Is Dongzao genetically modified? Dongzao is not genetically modified food.

Dongzao is a cultivated variety of jujube tree, which is a new variety obtained by grafting branches of jujube tree. Dongzao is one of the most excellent varieties of spinless jujube tree, with large and sweet fruit, thin skin and crisp meat, which is suitable for fresh eating.

It has curative effect on hypertension and atherosclerosis, and has the effect of preventing pain.

Correct understanding of genetically modified food

Genetically modified foods, like nuclear energy, are all YoYo products in the process of human development. How many countries are studying nuclear energy and using nuclear energy now, and how many countries have suffered major nuclear pollution because of nuclear energy? So are genetically modified foods. As long as all the foods tested and verified by the state are safe, there is no need to doubt that there are actually many genetically modified foods in nature, so people don't eat them as usual.

Matters needing attention in eating winter jujube

1, Dongzao is sweet and contains more sugar, so it is not suitable for eating more to avoid obesity.

2. Winter jujubes mature late in the season, and it is difficult to store and transport them. Therefore, most of the winter jujubes listed before maturity are fakes, which taste sweet and are soaked with pepsin. Pay attention to identification.

Is Dongzao Transgenic? 3 Dongzao (also known as Yanlaihong, Apple Jujube, Rock Sugar Jujube, Lubei Dongzao, Zhanhua Dongzao and Huanghua Dongzao) is a high-quality late-maturing fresh food species in northern Shandong. Winter jujube bears fruit early, and it can bear fruit in the same year of grafting. 10 ripens in the first half of October, and the fruit is nearly round, with smooth and smooth surface, and the fruit shape resembles a small apple. The longitudinal warp is 2.7-2.9cm, the transverse warp is 2.5-2.9cm, the average unit weight 14 g, and the maximum fruit weight is 45 g.

Winter jujube belongs to Rhamnaceae, Zizyphus. It is an excellent late-maturing and fresh-eating variety of spinless jujube. Mainly distributed in Hebei, Shandong and other places, the fruit of Dongzao jujube is large, nearly round, with a vertical and horizontal diameter of 2.9-3.2 cm, thin skin, small pit, juicy, tender and crisp meat, strong sweetness, slightly sour, round or oblate fruit with ochre red color, with an average fruit weight of 17.5g and a maximum fruit weight of 35g. Fresh jujube contains 34% sugar, 0.47% acid and 303 mg/100g vitamin.

So winter jujube is not a genetically modified food. What is genetically modified food? The target gene is introduced into the recipient cell, and the recombinant DNA molecule is injected into the recipient cell (also called host cell or host cell), and the cells with the recombinant are expanded to obtain a large number of cell propagators.

Whether it is the knowledge of genetically modified food safety or the knowledge of food safety, everyone should pay attention to: the chemical pollution in food includes pesticide residues, veterinary drug residues, hormones, food additives, heavy metals and so on. The harm of pesticide residues, animal residues and hormones to children is microecological imbalance of intestinal flora, diarrhea, allergy, precocious puberty and so on. Therefore, it is very important to clean and peel vegetables and fruits reasonably, choose animal food raw materials from regular manufacturers, and not eat large and ripening fruits.

The proliferation of food additives is the main problem of chemical pollution in children's food. Street vendors and food stalls around kindergartens are selling insecure, colorful and fragrant inferior food. In recent years, cases of middle school students' renal failure and blood diseases discovered by the medical profession have confirmed the harm of eating too many inferior snacks in childhood. Children's lead pollution is worthy of attention.

Foods related to lead are preserved eggs and popcorn; The related tableware is: ceramic products, glazed ceramic utensils and crystal utensils; Children's toys, inferior oil pastels and pictures made of lead paint or oil paints are one of the main ways of lead exposure, so it is necessary for children to wash their hands frequently. In addition, avoid eating food containing cards and toys. The safety of genetically modified food has not been determined, so try not to give it to children.
