Ginkgo biloba does not improve brain function. It turned out that ginkgo, which was promoted as a miracle-enhancing agent, did not work. Placebo is better! Fructose found in fruits is also not an ideal memory booster.

As it turns out, there are no certain things, also in science. What yesterday was considered the absolute, unquestionable truth, today may turn out to be just a myth. This was the case with spinach, for example. Children, especially those who are anemic, have been stuffed with it for years, due to their high iron content. Meanwhile, anotherresearch studyshowed that spinach is low in iron, just 2.8 mg per 100g. Which does not mean that spinach is a worthless vegetable, on the contrary, it has many other substances that are valuable to he alth, but not iron.

Spinach was raised to a pedestal because of iron only as a result of a laboratory technician's error, who put a comma in this place … And how many more such errors can be found in science? Certainly a lot.

Ginkgo biloba does not work on the brain

A similar story is with the ginkgo biloba ( Ginkgo biloba ) also called Japanese. More than 5000 years ago, this plant was known in Chinese medicine as a panacea forbrain . It was promoted as a miracle brain enhancer and memory enhancer, especially in the elderly.

Animal experiments were to show that the flavonoids contained in it have a positive effect on the elasticity of the brain's blood vessels, increase the blood supply to the brain, and "sweep away" free radicals from the body. In contrast, ginkgolides, another component of this plant, help prevent blood clots. Moreover, ginkgo extracts were supposed to combat many other symptoms of old age, such as mood swings, fatigue, and attention deficit disorder. In some reports there was information that in mature menginkgomay act like ginseng, which is almost like Viagra. It has been proven that it has the ability to improve the functions of the endocrine system, especially the work of sex hormones, which, as you know, decline with age. Here's a surprise! American scientists from the University of Pittsburgh took ginkgo under the microscope again (probablythey suggested spinach …). For six years they closely watched six thousand people who, in the appropriate doses, were administered ginkgo preparations. At the same time, another group, also six thousand, was given a placebo. And it turned out that ginkgo does not have the brain-enhancing properties that were attributed to it. In addition, studies have shown that in many cases a placebo has been shown to be more beneficial for the brain! So why such a mistake? Scientists explain it this way: 'You can't generalize that ginkgo is beneficial to brain processes, because it is not. Yes, favorable changes can occur, but only in some people. We will investigate which ones, we do not know yet. One more thing, these beneficial effects are short-lived. It is also worth knowing that some people taking preparations from this plant may experience side effects, such as headaches, digestive disorders, which should be a contraindication to the therapy.

And fructose can weaken the brain

The memory will not be improved by the fructose commonly found in fruit and honey - simple sugar, also called fruit sugar. It is an excellent nutrient, well and quickly absorbed by the tissues. Fructose had the reputation of a substance that has an extremely beneficial effect on the heart and brain, stimulating them to work better.

Scientists from the University of Georgia do not deny these beneficial properties, but prove that it is not quite like that. Well, in this case, it all depends on the quantity. Small and consumed in the most natural, unprocessed form, fructose significantly improves brain function and heart function. But consumed in excess, it has the opposite effect, it weakens cognitive functions, including memory and heart function. Fructose sugar, added as a sweetener in beverages and highly processed foods, can do the most harm. And such products should be avoided above all, although sweet fruits (bananas, grapes) should also be eaten moderately. Excess fructose in the body may improve brain function, but not for long.
