You might be surprised to learn chocolate contains flavonoids, which prevent heart disease, cancer and may even prevent weight gain.
Researchers wrote in the open access journal BMC Medicine combined the results of 45 studies into the effects of flavonols, the compounds in chocolate which cause dilation of blood pressure.
Flavonoids are antioxidants found in chocolate, vegetables, fruits, red wine and tea.
Antioxidants neutralize free radicals, which are linked to heart disease, cancer, stroke, premature aging and breakdown of the immune system.
Free radicals are highly reactive chemicals produced naturally during metabolism that act like biological rust to destroy membranes, DNA and critical cell structures.
Flavonols' main health benefit may be that they promote nitric oxide production by endothelium,the cells lining the blood vessels.
Nitrici oxide (NO) is a vital chemical that promotes blood flow and helps maintain a low blood pressure and a healthy cardiovascular system.
The inner lining of the blood vessels release NO, which helps control blood flow to the tissues.
Problems with energy levels, sexual performance and blood distribution are often due to the inability to secrete NO.
Italian scientist found that flavonols in chocolate lowered systolic blood pressure by 11 mm Hg and diastolic blood pressure by 9 m Hg, promoted blood vessel health and blood vessel diameter and reduced LDL (bad cholesterol) and insulin resistance.
Chocolate is a wholesome food but it is important to remember that it is also high in fat and calories so over-indulgence is not good for your heart.
Don't eat too much.
