Detoxification — or detox — is a popular buzzword.
It typically implies following a specific diet or using special products that claim to rid your body of toxins, thereby improving health and promoting weight loss.
Fortunately, your body is well-equipped to eliminate toxins and doesn’t require special diets or expensive supplements to do so.
That said, you can enhance your body’s natural detoxification system.
This article explains some common misconceptions about detoxing along with nine evidenced-based ways to rejuvenate your body’s detoxification system.
Detox diets are said to eliminate toxins from your body, improve health, and promote weight loss.
They often involve the use of laxatives, diuretics, vitamins, minerals, teas, and other foods thought to have detoxing properties.
The term “toxin” in the context of detox diets is loosely defined. It typically includes pollutants, synthetic chemicals, heavy metals, and processed foods — which all negatively affect health.
However, popular detox diets rarely identify the specific toxins they aim to remove or the mechanism by which they supposedly eliminate them (1).
Your body has a sophisticated way of eliminating toxins that involves the liver, kidneys, digestive system, skin, and lungs.
Still, only when these organs are healthy, can they effectively eliminate unwanted substances.
So, while detox diets don’t do anything that your body can’t naturally do on its own, you can optimize your body’s natural detoxification system.
SUMMARYWhile detox diets have a seductive appeal, your body is fully equipped to handle toxins and other unwanted substances.
More than 90% of alcohol is metabolized in your liver (4).
Recognizing acetaldehyde as a toxin, your liver converts it to a harmless substance called acetate, which is later eliminated from your body.
Excessive drinking can severely damage your liver function by causing fat buildup, inflammation, and scarring (10).
When this happens, your liver cannot function adequately and perform its necessary tasks — including filtering waste and other toxins from your body.
As such, limiting or abstaining entirely from alcohol is one of the best ways to keep your body’s detoxification system running strong.
Health authorities recommend limiting alcohol intake to one drink per day for women and two for men. If you currently don’t drink, you shouldn’t start for the potential heart benefits associated with light-to-moderate drinking (11).
SUMMARYDrinking too much alcohol reduces your liver’s ability to carry out its normal functions, such as detoxifying.
Ensuring adequate and quality sleep each night is a must to support your body’s health and natural detoxification system.
With sleep deprivation, your body does not have time to perform those functions, so toxins can build up and affect several aspects of health (16).
You should sleep seven to nine hours per night on a regular basis to promote good health (21).
If you have difficulties staying or falling asleep at night, lifestyle changes like sticking to a sleep schedule and limiting blue light — emitted from mobile devices and computer screens — prior to bed are useful for improving sleep (22, 23, 24).
Water does so much more than quench your thirst. It regulates your body temperature, lubricates joints, aids digestion and nutrient absorption, and detoxifies your body by removing waste products (25).
Your body’s cells must continuously be repaired to function optimally and break down nutrients for your body to use as energy.
However, these processes release wastes — in the form of urea and carbon dioxide — which cause harm if allowed to build up in your blood (26).
Water transports these waste products, efficiently removing them through urination, breathing, or sweating. So staying properly hydrated is important for detoxification (27).
The adequate daily intake for water is 125 ounces (3.7 liters) for men and 91 ounces (2.7 liters) for women. You may need more or less depending on your diet, where you live, and your activity level (28).
SUMMARYIn addition to its many roles in your body, water allows your body’s detoxification system to remove waste products from your blood.
Sugar and processed foods are thought to be at the root of today’s public health crises (29).
These diseases hinder your body’s ability to naturally detoxify itself by harming organs that play an important role, such as your liver and kidneys.
By consuming less junk food, you can keep your body’s detoxification system healthy.
You can limit junk food by leaving it on the store shelf. Not having it in your kitchen takes away the temptation altogether.
Replacing junk food with healthier choices like fruits and vegetables is also a healthy way to reduce consumption.
SUMMARYExcess junk food consumption is linked to chronic diseases like obesity and diabetes. These conditions can cause harm to organs important to detoxifying, such as your liver and kidneys.
Antioxidants protect your cells against damage caused by molecules called free radicals. Oxidative stress is a condition caused by excessive production of free radicals.
Your body naturally produces these molecules for cellular processes, such as digestion. However, alcohol, tobacco smoke, a poor diet, and exposure to pollutants can produce excessive free radicals (36).
Eating a diet rich in antioxidants can help your body fight oxidative stress caused by excess free radicals and other toxins that increase your risk of disease.
Examples of antioxidants include vitamin A, vitamin C, vitamin E, selenium, lycopene, lutein, and zeaxanthin.
SUMMARYConsuming a diet rich in antioxidants helps your body reduce damage caused by free radicals and may lower your risk of diseases that can impact detoxification.
Gut health is important for keeping your detoxification system healthy. Your intestinal cells have a detoxification and excretion system that protects your gut and body from harmful toxins, such as chemicals (43).
Good gut health starts with prebiotics, a type of fiber that feeds the good bacteria in your gut called probiotics. With prebiotics, your good bacteria are able to produce nutrients called short-chain fatty acids that are beneficial for health (44, 45).
Consequently, this unhealthy shift in bacteria can weaken your immune and detoxification systems and increase your risk of disease and inflammation (49).
Eating foods rich in prebiotics can keep your immune and detoxification systems healthy. Good food sources of prebiotics include tomatoes, artichokes, bananas, asparagus, onions, garlic, and oats (43).
SUMMARYEating a diet rich in prebiotics keeps your digestive system healthy, which is important for proper detoxification and immune health.
For some people, detoxing is a means of eliminating excess water.
Consuming too much salt can cause your body to retain excess fluid, especially if you have a condition that affects your kidneys or liver — or if you don’t drink enough water.
This excess fluid buildup can cause bloating and make clothing uncomfortable. If you find yourself consuming too much salt, you can detox yourself of the extra water weight.
While it may sound counterintuitive, increasing your water intake is one of the best ways to eliminate excess water weight from consuming too much salt.
That’s because when you consume too much salt and not enough water, your body releases an antidiuretic hormone that prevents you from urinating — and therefore detoxifying (50).
Increasing your intake of potassium-rich foods — which counterbalances some of sodium’s effects — also helps. Foods rich in potassium include potatoes, squash, kidney beans, bananas, and spinach (54).
SUMMARYConsuming too much salt can increase water retention. You can eliminate excess water — and waste — by increasing your intake of water and potassium-rich foods.
Regular exercise — regardless of body weight — is associated with a longer life and a reduced risk of many conditions and diseases, including type 2 diabetes, heart disease, high blood pressure, and certain cancers (55, 56, 57).
While some inflammation is necessary for recovering from infection or healing wounds, too much of it weakens your body’s systems and promotes disease.
By reducing inflammation, exercise can help your body’s systems — including its detoxification system — function properly and protect against disease.
It’s recommended that you do at least 150–300 minutes a week of moderate-intensity exercise — such as brisk walking — or 75–150 minutes a week of vigorous-intensity physical activity — such as running (60).
SUMMARYRegular physical activity lowers inflammation and allows your body’s detoxification system to work properly.
Although no current evidence supports the use of detox diets for removing toxins from your body, certain dietary changes and lifestyle practices may help reduce toxin load and support your body’s detoxification system.
- Eat sulfur-containing foods. Foods high in sulfur, such as onions, broccoli, and garlic, enhance excretion of heavy metals like cadmium (61).
- Try out chlorella. Chlorella is a type of algae that has many nutritional benefits and may enhance the elimination of toxins like heavy metals, according to animal studies (62).
- Flavor dishes with cilantro. Cilantro enhances excretion of certain toxins, such as heavy metals like lead, and chemicals, including phthalates and insecticides (63, 64).
- Support glutathione. Eating sulfur-rich foods like eggs, broccoli, and garlic helps enhance the function of glutathione, a major antioxidant produced by your body that is heavily involved in detoxification (65).
- Switch to natural cleaning products. Choosing natural cleaning products like vinegar and baking soda over commercial cleaning agents can reduce your exposure to potentially toxic chemicals (66).
- Choose natural body care. Using natural deodorants, makeups, moisturizers, shampoos, and other personal care products can also reduce your exposure to chemicals.
While promising, many of these effects have only been shown in animal studies. Therefore, studies in humans are needed to confirm these findings.
SUMMARYSome lifestyle and dietary modifications may enhance your body’s natural detoxification system.
Detox diets are said to eliminate toxins, in turn improving health and promoting weight loss.
But these diets — while seductive — aren’t needed as your body has its own, highly efficient detoxification system.
That said, you can enhance your body’s natural detoxification system and improve your overall health by staying hydrated, consuming less salt, getting active, and following an antioxidant-rich diet.
