Many of the therapeutic effects of garlic are thought to be due to its volatile factors which are composed of the sulphur-containing compounds, high concentrations of trace minerals, glucosinolates and enzymes. Two garlic cloves have approx. 10 calories and bucket loads of flavour. Garlic, unlike salt, has no negative effects on your blood pressure so try to use more in cooking along with herbs and spices and pepper. My practical nutrition suggestion Chopping or crushing the garlic stimulates the release of allicin, a compound to which many of garlic’s health benefits are attributed, such as protecting against heart disease and lowering cholesterol and blood pressure. It is best to leave about fifteen minutes between crushing and cooking to maximise the health benefits of allicin.
