The fruit of the vine, the grape is one of the most widely consumed fruits and the one used to make wine, a traditional product. It is a fruit that grows in bunches and whose origin dates back to the Caucasus and Western Asia. In fact, it is believed that in the Paleolithic era this fruit was already being harvested for consumption and that in ancient Greece and Rome viticulture was developed.

Beyond its particular history, the truth is that grapes have an important nutritional value and are a staple food in the Mediterranean diet. It is mainly composed of water (specifically 82.4 grams per 100 grams consumed), so the caloric value is low, just 69 kilocalories, ideal as a diuretic.

For a long time it has been held that wine was a healthy food because it had all the properties and nutrients of grapes, but there is increasing evidence that alcohol is toxic and that what is really healthy are the grapes.

Grapes have an important amount of potassium, vitamin B6 and vitamin C, which contribute to enrich the diet, as well as phytonutrients and flavonoids. Their composition varies depending on the type of grapes, whether they are white or black, although in general their contribution of carbohydrates is greater than with other fruits.

This is the main reason why they provide us with a lot of energy. They are easily assimilated carbohydrates such as glucose, fructose, sucrose, dextrose and levulose. Grapes are also rich in phenolic compounds, especially stilbenes (resveratrol) and flavonoids.

The health benefits of this fruit are mainly due to the presence of bioactive substances, which are responsible for its color, aroma and texture. The polyphenols present in its nutritional composition have a very strong protective activity in the cells because they have inhibitory effects on agents that damage them, such as free radicals.

Thus, resveratrol also has important benefits for the heart, especially for the protection of arteries and cardiovascular health. On the other hand, the presence of vitamin B6 and folic acid is really important for the metabolism of our body, while the seeds are rich in essential fats of the omega 6 type.
