Almost all now know the importance of carrots, red fruit, tomatoes, which contain beta-carotene, a precursor of vitamin A, magical substance that combines the action of melanin and therefore helps us to achieve a beautiful and colorful summer faster.
But let's first talk about degrees and beta-carotene: it is an orange pigment content in many fruits and vegetables which gives a color ranging from yellow to red. Once he arrived in the intestine, it is converted in part into vitamin A, important for healthy skin and eyes, while the rest is absorbed and stored as such.
Here we have some details on the melanin is essential for humans as it protects from the sun's ultraviolet radiation, as well as allow the skin to take on the dark tan. But beware: there is no relationship between the intake of beta-carotene and melanin production! The production of the latter depends only on exposure to the sun, it was not shown any connection with the intake of carotenoids.
The great importance given to beta-carotene is due to the fact that, ingested through the mouth and accumulate in adipose tissue and skin, makes the skin take on the characteristic orange color. Therefore, the color orange, joining the brown color of melanin, helps in obtaining a rapid, intense coloration and pleasing to our tan.
Now we speak of foods: gorging is not necessary, it takes only 100 grams per day of carrots (which have a content record 1200 micrograms of vitamin A per 100 grams of product), apricot (500 micrograms per 100 grams of product), tomatoes , yellow squash and strawberries. And yet we do not neglect salads, chicory, lettuce, melons, peppers, cherries, cucumbers.
And if you do not appreciate the fruit, you can eat 50 grams per day of parmigiano reggiano, grana padano cheese, or pecorino cheese. One can associate with this "diet" even the yolk of the egg. In this way you create a mix of foods that can be up to half the time to reach an optimal tan, you just expose yourself to the sun, of course, always sprinkled with a sunscreen with UVA-UVB rays.
Of course, these cheeses can be delicious for many, as well as the egg, but during the summer the heat makes you sweat a lot, causing us to lose water and minerals: they must be replenished possibly with refreshing foods like fruits and vegetables rich in potassium, calcium and iron, which are essential to restore the balance of our body, we also avoid gaining weight in order to maintain the shape for summer great.
Plant foods therefore we are meeting various requirements quench their thirst, nourish, replenish minerals, provide vitamins, maintain efficiency in the intestinal tract through the fibers that contain counteract the effects of free radicals produced in the body as a result of exposure to the sun.
It 'always good to remember that in the early days at sea must gradually accustom the skin to the sun. The tan surface of the early days is due to the amount of melanin immediately available, but it is destined to disappear quickly; only after about a week begins to form long-lasting tan. We must avoid being in the sun for too long a time: the best times to tan are the morning until 12 o'clock and the late afternoon, so avoid the hottest hours of the day (from 12 to 15).
Finally, especially if you do not have a way to expose yourself to the sun in a diligent and constant, it is advisable to take foods that help prolong your tan, ie, milk and fish, which contain omega 3 and omega 6, which are important for the formation and synthesis collagen and rilastina that also make the skin supple and nourished.
A last note concerns the protective creams: some of them are among the ingredients in beta-carotene, but its activity is nothing short of anything since the conversion to vitamin A occurs only in the intestine. Although creams already contain vitamin A would always be completely useless in this regard.
