Já lead usually contaminates cocoa after harvest, during outdoor drying, through dust and atmospheric particles. Consumidores should seek source information to minimize long-term exposure to these heavy metals.

Evolução history and impact on human vascular health

Hoje, science focuses on the biological compounds present in the original seed.

Ensaios clinical trials demonstrate that cocoa flavanols, such as epicatechin, improve endothelial function. Isso means arteries respond better to blood flow and physical stress.

• The average caloric density of 100 grams of dark chocolate exceeds 600 calories.
• Excess weight gain can negate the benefits for blood pressure.

Riscos of excessive consumption and criteria for choosing the product

The presence of lead and cadmium in the human body can cause kidney damage and neurological development problems.
