After autumn and winter, the weather turns colder and apples become the most popular fruit. Since late autumn to the next spring can eat it almost every day, we even gave it a crown of praise “people’s table on the small medicine box”, it can be imagined that everyone on the apple health efficacy of recognition. However, most of my friends only stay at a higher level of vitamin content for apples. In fact, the nutrients contained in this common fruit are not just vitamins. Today, we unveil another layer of health care veil for apples together with nutritionists.
Apple, belonging to the family Rosaceae fruit, is the main fruit in China and the world’s largest fruit production. The content of carbohydrate is 13.5g per 100g of apple, among which the trace elements calcium, potassium, phosphorus, zinc, vitamin B1, vitamin B2, vitamin C and carotene are abundant.
Apple one of the health effects: nutrition nervous system, improve memory ability
The zinc in apples plays an important role in body health. Zinc deficiency can cause a number of symptoms, including stunted growth, fertility and sexual dysfunction, decreased taste and appetite, brain development and neurological disorders. Zinc deficiency affects both the central nervous system and the peripheral nervous system, because the hippocampus and cortex of the brain contain the highest levels of zinc in both humans and mammals. After central nerve is damaged, affect learning ability, memory, affection stability, because this performance intelligence is low, memory is bad. The high content of zinc in apple can improve memory and intelligence, so apple is also known as “memory fruit” and “wisdom fruit”.
Apple health effects of two: rich trace elements, improve hypertension
Potassium per 100g apple contains up to 119mg, potassium plays an important regulatory role in the balance of water and body fluids, potassium and cell metabolism is closely related. At the same time, a number of studies have shown that a high-potassium diet can reduce blood pressure, and has a hypotensive effect on patients with mild hypertension and some normal blood pressure patients with hypertension factors. The mechanism is mainly in two aspects. On the one hand, the increase of renal K+ in circulation leads to the increase of Na+ excreted in urine. On the other hand, it may be related to K+ inhibition of renin angiotensin system and sympathetic nervous system, improvement of the function of pressure receptors, and direct influence on peripheral vascular resistance, etc. Therefore, apple has the effect of improving blood pressure.
Apple health effect three: the right amount of dietary fiber, reduce the body trouble
The dietary fiber in apples can improve the function of the large intestine, which is the main place to store feces. Dietary fiber can increase the amount of feces, shorten the time of feces in the intestine, thus improving the difficulty of defecation. At the same time, dietary fiber also plays a role in lowering plasma cholesterol, reducing the incidence of cardiovascular disease.
