Most detoxification programs recommend removing highly processed foods and foods to which some people are sensitive, such as dairy, gluten, eggs, peanuts and red meat. They also recommend eating mostly organically grown vegetables, fruit, whole non-glutenous grains, nuts, seeds and lean protein.
It seems everyone is talking about "detox" or considering a "cleanse." Detox diets often are misunderstood — especially since your body already comes equipped with a detoxification system. Understanding how detox works may help clear up some confusion.
How the Body Naturally Detoxifies
Detoxification is a process that the body performs around the clock utilizing important nutrients from the diet. It's the process that transforms toxins so they can be removed from the body. They fall into two main categories: toxins that are made in the body during regular metabolism, and those that come from outside the body and are introduced by eating, drinking, breathing or are absorbed through the skin.
Toxins that are produced in the body include lactic acid, urea and waste products from microbes in the gut. External toxins may include pesticides, mercury in seafood, lead from car exhaust and air pollution, chemicals in tobacco products and drugs or alcohol.
Detoxification also uses the process by which medications are metabolized and removed from the body. Because toxins are potentially dangerous to human health, they need to be transformed and excreted through urine, feces, respiration or sweat. Each person's ability to detoxify varies and is influenced by environment, diet, lifestyle, health status and genetic factors, suggesting some people may require more detoxification support than others. But if the amount of toxins to which a person is exposed exceeds his or her body's ability to excrete them, the toxins may be stored in fat cells, soft tissue and bone, negatively affecting health. This is the rationale behind the use of practices that support the body's own detoxification capabilities, but more research is needed.
Most detoxification programs recommend removing highly processed foods and foods to which some people are sensitive, such as dairy, gluten, eggs, peanuts and red meat. They also recommend eating mostly organically grown vegetables, fruit, whole non-glutenous grains, nuts, seeds and lean protein. Other programs recommend fasting, a potentially risky practice for some people, which may actually suppress detoxification pathways in the body. This is why many health practitioners advise against this practice.
Many noncredentialed people claim to be experts in detoxification; however, there is a lack of research at this time to support its use. Plus, detoxification programs can vary widely and may pose a risk for some people (such as people with health problems, those with eating disorders, those who take multiple medications, and pregnant or breastfeeding women).
8 Ways to Support Your Body's Natural Detox
Detoxification support doesn't need to consist of a rigorous plan; doing some or all of the following can support your body's natural detoxification:
Stay hydrated with clean water.
Eat five to nine servings of fruit and vegetables per day.
Consume dietary fiber each day from vegetables, fruits, nuts, seeds and whole grains to help maintain bowel regularity.
Include cruciferous vegetables, including broccoli and Brussels sprouts, berries, artichokes, garlic, onions, leeks and green tea. These support detoxification pathways.
Consume adequate amounts of lean protein, which is critical to maintaining optimum levels of glutathione, the body's master detoxification enzyme.
Consult your health care provider or registered dietitian nutritionist if you're interested in taking a multivitamin/multimineral to fill any gaps in a healthy diet.
Eat naturally fermented foods such as kefir, yogurt, kimchi and sauerkraut — these may help promote a healthy gut.
If you have questions about your eating style and its role in supporting the body’s detoxification, check in with a registered dietitian nutritionist. RDNs can provide sound, easy-to-follow personalized nutrition advice to meet your lifestyle, preferences and health-related needs.

With a quick scan of this list, it's safe to say berries are the equivalent of leafy greens in the vegetable world. They're packed with fiber (8 grams per cup—that's about a third of your daily needs!), contain a variety of phytonutrients, and their net antioxidant effect is, gram for gram, second only to herbs and spices.
Additionally, a 2011 study3 showed that consuming 60 grams of black raspberry powder slowed the growth rate of colorectal cancer cells and the blood vessels that supply them in two to four weeks. Researchers believe that the fruit phytochemicals stimulate our own enzyme defenses that neutralize cellular waste products known as free radicals, which, left unchecked, promote cellular deterioration and lead to cancerous mutations.
Admittedly, most of the berry/cancer research has measured the effect of a berry extract on human cancer cells in a test tube. But Dr. Shetreat believes that berries as a complementary therapy for cancers of the colon, prostate, and breast looks promising. The colon cancer connection makes especially good intuitive sense, she adds, since the fiber in the fruit feeds good bacteria in the gut, which then produce organic acids, which then feed the cells that protect the colon's lining. Bonus: Raspberries are also a great source of vitamin C.
