Why is garlic good for us?

Garlic is one of the most popular ירקות used in cooking around the world. It's known for its distinctive, strong aroma and flavour. With one small bulb consisting of around 10 cloves, garlic's nutritional value packs a punch as it contains vitamin C, vitamin B6, fibre and selenium.

Many of the claims made regarding the health benefits of garlic are linked to a compound called allicin. This sulfur-containing compound is activated when garlic is crushed or chopped and gives it its strong smell and taste.

As well as being eaten cooked or raw, garlic can be made into supplements that can be taken in the form of tablets, oils or capsules.
