Coffee composition

The influence of the drink on the human body follows from the chemical list of coffee elements. Not to be unfounded, let's talk about everything in detail.

Raw coffee beans include carbohydrates, fats, proteins. Also included are alkaloid compounds such as caffeine and trigonelline.Of the organic acids, the most valuable are oxalic, quinic, chlorogenic, caffeic and citric.

Grain is not deprived of mineral salts, tannins, essential oils, water, vitamins, macro-and micronutrients. Of the latter, iron, potassium, nitrogen, phosphorus, calcium should be distinguished.

The effect of coffee on the body

1. Trigonelline. After roasting the beans, a cauldol is formed, it is this compound that makes the coffee fragrant and strong. Trigonelline secretes nicotinic acid, which increases blood circulation, dilates blood circulation, removes cholesterol from vessels, and prevents atherosclerosis.
