Eating Garlic: What are the Health Benefits & Side Effects?

Garlic, a kitchen must-have has also been known for its therapeutic benefits in the prevention and treatment of a variety of illnesses and in maintaining gut health. Recent studies have recognized the effects of garlic and its extracts in a variety of applications. Packed with potent chemicals, research has shown that it can reduce the risk of cardiovascular diseases, exhibit anti-tumor and anti-microbial characteristics, and alleviate elevated blood glucose levels. 

Ways of Consuming Garlic  

Way 1: Include Them in Your Cooked Meals 

As it has been a part of Indian and many other cuisines for ages; garlic can be added to any stews, curries, some sauces, marinations, etc. 

  1. You can simply wash and finely chop the garlic, before cooking.
  2. In particular, when garlic is added to vegetables cooked in clarified butter or ghee, it doesn't increase cholesterol. 

Way 2: Consuming Raw Garlic

Although consuming raw garlic may not be the choice of most given its pungent smell and overwhelming flavour, it can be a healthy choice. Raw garlic retains allicin, a compound that contains sulfur, responsible for many of garlic's beneficial health effects making it an ideal spice to be consumed in its natural form. 

  1. Chop a garlic clove into 3-4 pieces, then place it on a spoon. 
  2. Add a few drops of honey and set it aside for a couple of minutes. 
  3. Just take a bite, chew the garlic, then swallow it. 

If you find the taste of garlic to be a little too strong, you can also take two to three sips of warm water along with it.
