Eating garlic on an empty stomach actually transforms it into a powerful natural antibiotic. It becomes more effective when you take it before breakfast, since the bacteria is exposed and defenseless. The allicin in garlic has a strong bacteriostatic effect which helps cure infections faster. It works as a very strong antibiotic, making it essentially a natural and healthy filter for your stomach.
Garlic is best eaten crushed, whether raw or cooked. Crushing damages the cells and allicin is released. Garlic destroys free radicals due to its anti-oxidant properties, but it should be consumed within an hour or two of activating the allicin (by crushing or mincing the garlic) to get the full potential health benefits.<.p>
Heat can destroy allicin and its resulting sulfur containing compounds. So recipes that call for cooking garlic at high heat for long periods of time cancel out most of its healthy boost.
To benefit the protective effects of garlic, you should at least have 2 medium sized garlic cloves everyday.
