Onion and garlic are both members of the allium family of vegetables, which provide pungent flavors to foods. These plants contain flavonoids that stimulate the production of glutathione, one of the liver's strongest antioxidants. As a result, they both have powerful anti-bacterial and immune-boosting properties.
Other fresh veggies (greens) are a good source of glutathione-essential for detox of the liver pathway. Fresh vegetables can also provide excellent sources of insoluble fiber, which gets the gut moving.
Crisp, crunchy raw veggies are highest in this sort of fiber. Think kale, collards and broccoli (but watch out for these 14 Dirtiest Fruits and Vegetables).
Wheatgrass, commonly served in powder or juice form, is rich in vitamins and minerals. While scientific evidence to support health claims about wheatgrass is lacking, products containing wheatgrass may add some yummy, low-calorie variety to your selection of cleanse foods and beverages.
Yogurt that contains probiotics—make sure to check the label—supplies healthy bacteria that fortify the GI tract's natural flora, aiding digestion and boosting the body's natural immune responses.
