Grape seeds (and raisins) naturally present in this fruit, provide nutritional elements with antioxidant and anticarcinogenic properties. As well as important benefits for the treatment of venous insufficiency and different types of edema.
Vitamin E, flavonoids, linoleic acid, and OPC (oligomeric proanthocyanidins) are highly concentrated in grape seeds. These compounds can also be found, to a lesser extent, in grape skins, grape juice and wine, but always in lower concentrations.
Resveratrol is another grape compound that is related to OPCs, being found mainly in the grape skin. Resveratrol has become very popular as an antioxidant, and its relationship to a wide variety of diseases is being studied.
In laboratory tests, grape seeds have also been shown to have anti-inflammatory and anti-cancer properties. Likewise, in vitro tests have demonstrated their impact in the fight against lung, breast and stomach cancers.

Grape seeds have a host of beneficial properties both aesthetically and for our health. This hidden treasure in every grape can not only be consumed with the fruit itself, but is also marketed in oil, capsules and extracts, and is a basic component of many beauty products.
Grape seeds are very difficult to digest. However, there are different ways of consuming them to make the most of all their properties. We can rehydrate them for a couple of hours before eating them, add them to smoothies or even eat them on their own. The important thing is to chew them and crush them well with your teeth to release their many nutritional properties.
Grape seeds, with antioxidant effects and a high vitamin E content, help purify the blood and control triglycerides. In addition, as they increase good cholesterol, they prevent hypertension and obesity.
The taste of virgin grape seed oil is similar to that of red wine, while refined grape seed oil has a rather neutral taste. It is very suitable for frying, as it is the oil that best withstands high temperatures and takes longer to boil than the others.

“Since both the father and mother we use are seedless, we are forced to do in vitro culture. It happens the same as in other species when there are difficulties in reproduction. Once those embryos have sprouted and become seedlings, we move on to the acclimatization phase, because these plants had nutrient gel as substrate and very controlled atmosphere. Then we moved on to very prepared soil so that the roots and leaves become functional. From this process we obtain the hybrids,” says Tornel. Once they have found the variety they were looking for and the plant has developed, they take a small piece of the plant and graft it. This form of vegetative reproduction is also very common in wine grapes.
To have a more elaborated opinion on the taste of seedless grapes, we asked Laura Veraguas, head of the gastronomic project -focused on the vegetable universe- Ver Aguas. “It is a flavor designed to please everyone, so it is flatter than the original grapes. The skin can have astringency or a more bitter taste that, with the sweetness, gives you a more complex flavor. Sometimes, in these crossings, interesting nuances of the skin are lost”.

Putting aside the fear of choking or the convenience of removing them, the answer is a resounding no from a nutritional standpoint. Not only is it not bad, but eating the seeds has benefits for the body. Grape seeds prevent cardiovascular diseases and improve blood circulation. They contain vitamins C and E, beta-carotene and polyphenols which, in addition to strengthening the immune system, prevent premature aging thanks to their antioxidant action.
Grapes are a source of vitamin C and, to a lesser extent, of group B vitamins (B1 and B2). They are also rich in minerals, especially potassium, copper, iron and calcium, but that’s not all. Together with vitamin C, what makes grapes a powerful beauty “elixir” is their high content of polyphenols, phytonutrients with a great capacity to stop the action of free radicals, the main causes of cellular and skin aging. Of all of them, resveratrol stands out, which is found in the skin of the fruit, especially in dark-colored grapes.
