Cuánto chocolate negro hay que comer al día para obtener beneficios cardiovasculares reales, según la ciencia – Infobae

Research into cardiovascular health indicates that the consumption of dark chocolate, particularly varieties with high cocoa content, is associated with a lower risk of heart disease, strokes, and other cardiovascular disorders.

Cardiologist Aurelio Rojas has noted that individuals who consume dark chocolate more than once per week may experience up to an 8% reduction in the risk of suffering a heart attack.

The cardiovascular benefits are primarily attributed to the presence of flavonoids and polyphenols. These antioxidants are found in high concentrations in dark chocolate and contribute to the protection of the endothelium, which is the inner layer of the blood vessels.

According to reporting from Infobae on May 11, 2026, these bioactive compounds help the blood vessels relax, which in turn reduces blood pressure and combats inflammation within the cardiovascular system.

The effectiveness of dark chocolate in managing blood pressure depends heavily on the quantity consumed and the purity of the product. Scientific data suggests that consuming between 6 and 25 grams of dark chocolate daily over a period of two to four weeks can lead to reductions in both systolic and diastolic blood pressure.

This effect is particularly beneficial for individuals dealing with mild or moderate hypertension.

However, not all chocolate provides these health benefits. For the effects to be significant, the product must contain at least 70% cocoa. The levels of beneficial flavonoids decrease in chocolates with lower cocoa purity and higher sugar content.

Beyond immediate cardiovascular indicators, there is evidence suggesting that chocolate consumption can influence longevity, provided the product contains specific healthy ingredients.

The synergy of antioxidants and the ability to maintain blood pressure within healthy ranges positions high-cocoa dark chocolate as a supportive element in a heart-healthy diet.
