Scientists from South Korea, Germany and Japan in experiments on rats have shown that the smell of fried coffee grains leads to changes in work of some genes and manufacture of fibers in a brain which help to lower consequences of stress because of dream deprivation.

Researchers have found out, that at rats, which smelled coffee, 17 genes «were working” differently. In particular, the coffee smell promoted allocation of the fibers possessing antioxidative properties; they protect nervous cells from the damages connected with stress.

Scientists have developed a new product for vegetarians under the name «tempe». It allows an organism not only to acquire iron easy, but also provides it with a lot of proteins. Its value consists in the integral grains rich with the folic acid (the water-soluble vitamin of group B necessary for growth and development of blood and immune systems). At its creation before scientists there was a purpose to keep in a product the high maintenance of fibres of grain crops and simultaneous to increase the maintenance of easy assimilated iron in them, that is impossible by the definition. Nevertheless, they managed to reach this purpose.

It is known, that integral grains reduce risk of cardiovascular diseases, and are capable to interfere with development of diabetes, and also some forms of a cancer that makes the given product popular not only among vegetarians and the people, preferring to eat meat as small as possible, but also among those who attentively concern to their health.

This substance is named resveratrol, it has the ability to slow down the ageing. Scientists of Wisconsin-Madison University (USA) investigated its rejuvenating effect. At work with rats they have noticed, that small dozes of this substance protect heart from the infringements, peculiar for declining age.

«How it turns out, that the Frenchmen which diet is rich with fats, have healthy heart and much less often suffer cardiovascular diseases than the Americans?» — scientists were asked. The answer has been found in the red wine. The Frenchmen, as well as Spaniards, during the meal drink usual the glass of wine, and this drink, containing resveratrol, protects an organism from some nocuous consequences of ageing.

“Our work shows, that inclusion of a glass of wine or the additive containing resveratrol in the diet after middle age, is so effective for prevention of consequences of ageing, as a meal with restriction of calories and fats”, — researchers mark. Considering, that many illnesses of older persons are connected with process of ageing, “this discovery can be of great importance for public health services as it will allow to lower some cardiovascular diseases and to improve quality of people life”, Thomas Prolla, the professor of genetics and one of authors of research, adds.

Canadian scientists from Toronto University have found out that predilection for sweet food can be explained by genetic features of the person. On their data, carriers of one of the GLUT2 gene variants consume the raised quantity of sugar.

Scientists under direction of Ahmed el-Soemy studied every day diet and flavoring predilections of group of the elderly participants, suffering excess weight or adiposity, and groups of healthy thin young men. Also the analysis of blood for definition of GLUT2 gene has been taken from all volunteers. This gene supervises the delivery of sugar (glucose) in cells.

It was found out, that carriers of the certain variant of GLUT2 gene in both groups of participants consumed more glucose, fructose and saccharine, than the others. In particular, the young men carrying this genetic variant, consumed more of sweet drinks and sweets, have noted scientists. At the same time researchers have informed that the volume of consumption of proteins, fats and alcohol remained the same, as well as with other participants.

«Results of research will help to explain some of individual preferences. It is especially important in view of growing distribution of adiposity and diabetes in the world”, — summarized Ahmed el-Soemy.

New researches showed that children who eat every day in a family circle have more healthy preferences in meal, than children who eat separately. More it, probability of that the second group of children at teenage age will be subject to risk of excessive weight, grows twice. It is important also the following law: that the more often children eat with family, it is less probability of that in the future they will suffer from depressions, various mental frustration and, that is very important, from such bad habits, as smoking, abusing spirits and drugs.

According to Doctor Nensi Rodriguez from the USA Department of the Food-Processing Industry, family meal matters not only for strengthening family relations, but as it has appeared, also for the general health of all family members. That fact is interesting, that involving of children in food shopping and drawing up of the menu on every day, is also invariable influences their preferences in meal.
