The unknown and beneficial effect of habitual consumption of red grapes and blueberries

Regular consumption of red grapes and blueberries can play a fundamental role in the prevention of cardiovascular diseases and heart care. This is revealed by research carried out by the Cardiovascular Risk Chair of the Universidad Católica San Antonio de Murcia (UCAM), directed by Dr. José Abellán-Alemán, together with the British hospitals West Hertfordshire Teaching Hospitals NHS Trust and the firm Nutritional Insight.

The work, published in the international scientific journal Nutrients, shows that the presence of resveratrol and anthocyanins among its components contributes to regulating blood pressure and improving certain indicators related to cholesterol and inflammation, especially in people with risk factors.

In the case of grapes, researchers have paid special attention to new red-fleshed varieties such as Boombite Murciana, which contain these compounds both in the skin and inside the fruit, in considerably higher proportions than traditional light-fleshed grapes. Regarding blueberries, it has been observed that regular consumption can improve endothelial function and arterial stiffness, two important indicators of the health of blood vessels for correct blood flow.

Other healthy varieties

The presence of red, bluish or purple tones in the color of its pulp or skin is due, in part, to polyphenolic compounds called anthocyanins. These natural pigments have antioxidant and anti-inflammatory properties that can help protect cells against oxidative damage and promote cardiovascular health.

In addition to red grapes and blueberries, Professor Abellán-Alemán highlights four other groups of fruits that can be easily incorporated into a heart-healthy diet: pomegranate, citrus fruits, apples and cherries.

Pomegranate is a classic for cardiovascular health that, due to its high polyphenol content, has important antioxidant properties that help neutralize free radicals and protect cells against oxidative damage. Citrus fruits, such as orange, lemon, grapefruit and lime, are rich in flavonoids - phenolic compounds that help regulate blood pressure - and provide potassium, an element that helps balance sodium levels in the body.
