Garlic: Garlic has long been known for its heart benefits, however the pungent food is also good at detoxifying the body. Garlic is not only antiviral, antibacterial and antibiotic, but it contains a chemical called allicin which promotes the production of white blood cells and helps fight against toxins. Garlic is best eaten raw, so add some crushed garlic to a salad dressing to boost its flavour and your health at the same time.
