“Yuck.” Faced with the fact that each of us is continually being exposed to all sorts of toxins — in the air we breathe, the water we drink, the food we eat and the products we use every day — is there really any other reaction to have?
Well, fortunately, yes. Because while “yuck” is certainly an understandable response, it’s not going to help these bodies of ours shovel out from the mess. And while they’ve been brilliantly designed to eliminate a wide variety of harmful elements, when our built-in detox systems get bogged down and start falling behind on their work, the results can be ugly — and eventually, even deadly.
That’s why the best approach to supporting your body’s natural detox systems is an ongoing one. By taking a few simple, daily steps, you can help scrub each of your body’s major elimination systems and enable them to function more efficiently. This empowers your body’s immune and repair systems to do the work they were meant to do: keeping you healthy, vital and resilient, even in the face of unpredictable challenges.
We’re not talking about monk-like obedience to an extreme diet or a faddish cleansing routine. Rather, we’re talking about gradual, sustainable lifestyle shifts that promote detoxification from the inside out. Here’s your guide to supporting each of your body’s six major elimination systems (kidneys, lungs, liver, bowels and intestines, lymphatic system, and skin), plus some insights into what causes toxins to accumulate, and the toxicity signals each system may send when it’s getting behind in its work.
Functions: The kidneys control the amount of water, acidity and minerals in the blood. They filter waste and toxins from the blood and play an important role in regulating blood pressure. They also help deliver oxygen to all the body’s cells.
Toxic signals: infrequent urination; dark or cloudy urination; frequent urinary-tract infections.
Contributing factors: dehydration; high cholesterol; a diet high in sodium, low in fiber, and high in refined flours and sugars.
Daily detox: Experts agree that hydration is the key to helping out your kidneys. “Kidneys need a lot of good healthy fluid — lots of water especially — for them to function properly,” says Alex Jamieson, author of The Great American Detox Diet (Rodale, 2006). While individual needs may vary, the Institute of Medicine, an independent research organization offering evidence-based advice to policymakers, health professionals and the public, recommends between 90 and 125 ounces of water each day. Other healthy beverages include diluted fruit juices and herbal tea. Avoid undoing all your good work by loading up on chemicals that leach water from your body, such as caffeine and alcohol.
You can ease the stress on your kidneys by adopting healthy habits that lower your blood pressure, such as getting some exercise each day and limiting your sodium intake — this is especially helpful for those who have sodium-sensitive high blood pressure. (For more on sodium intake and cooking with high-quality salts, see “Salt” in the January/February 2008 archives.)
Because high levels of LDL cholesterol can affect kidney function, you’ll want to emphasize healthy foods that can help reduce those levels (walnuts and almonds, tuna and salmon) — plus eat lots of brightly colored fruits and veggies, which help fight the inflammation that can drive up LDL. You’ll also want to reduce your intake of unhealthy fats. That means going easy on the bacon and sausage, as well as many premade baked goods and snacks that often contain both trans and saturated fats. (For more on good and bad fats, see “Fat Chance” in the January/February 2006 archives.)
Functions: The liver is the body’s hazmat specialist, removing all sorts of toxins from the blood. It also regulates blood-sugar levels, stores nutrients and serves as a garbage disposal for old red blood cells.
Toxic signals: bloating, nausea, indigestion, a tongue with a white or yellowish hue, yellowed eye whites.
Contributing factors: too much alcohol; too much unhealthy saturated or trans fat; overuse of prescription and over-the-counter medications; environmental exposure to heavy metals.
Daily detox: The liver is one of the body’s most powerful detoxifiers. It functions best when you eat more veggies, fewer processed foods, and less unhealthy fat, and when you keep your alcohol, sugar and caffeine intake low.
The liver thrives in an alkaline environment. Most vegetables have an alkalizing effect on the body, as do lemons and limes — an easy addition to your next glass of water. Refined sugars, flours, meats and dairy all have an acidifying effect. (For more on acid-alkaline balance, see “The pH Factor” in the March 2007 archives.) An excessive intake of unhealthy fats (particularly trans fats), sugars or alcohol can also bog down the liver, causing it to develop fatty deposits and become inefficient. Also limit your caffeine consumption. Its stimulating effect sets off a cascade of bodily reactions that can stress the liver and depress metabolism.
Finally, take a pass on most white foods: white bread, white rice and white flour, all of which send blood sugar spiking and the liver into overdrive. Instead emphasize liver scrubbers like cruciferous veggies (cabbage, cauliflower, broccoli); leafy greens; sulfur-rich foods (garlic, onion, radish); and artichokes, beets, asparagus and celery. For more tips, see “Fast Track Liver Detox” in the May 2005 archives.
Bowels and Intestines
Functions: Bowels and intestines absorb nutrients and moisture into the body and eliminate waste.
Toxic signals: constipation, diarrhea, bloating and gas; chronic skin problems; bad breath.
Contributing factors: a low-fiber diet; lots of processed or overly fatty and rich foods; pesticide residues; stress; delayed-onset food allergies or intolerances.
Daily detox: Avoid any foods to which you might be sensitive (typical culprits are gluten, dairy, corn, soy, eggs and tree nuts). Add fiber to your diet by eating foods such as pears, berries, figs, lentils, black beans and Brussels sprouts. Eat slowly: Fiber can be challenging for your body to digest in large quantities — especially if it’s been gulped down or not chewed thoroughly. Help out your digestive juices by chewing food to a liquid texture before you swallow; or try a digestive enzyme supplement.
Jamieson suggests taking probiotics, friendly bacteria that assist with digestion. Plain yogurt and kefir also are good sources of friendly bacteria. (For more on probiotics, see “Good Bacteria Welcome” in the July/August 2007 archives.)
Constipation can be both a sign and a cause of toxicity. When you suffer chronic constipation, you run the risk of the toxins in your waste being reabsorbed into your body, rather than passing quickly through. Talk about “yuck!”
To help alleviate constipation, Jane Alexander, author of Holistic Therapy File (Carlton Publishing Group, 2008), recommends (in addition to consuming more water, fruit and veggies) a yoga position called the Cobra Pose. Lie face down on the floor and put your hands beneath your shoulders. Aim to straighten your arms and arch your back as far as is comfortable (don’t strain). Look up or straight ahead. Hold the position for as long as is comfortable, and then return to the floor.
Functions: The lungs bring oxygen from the air to our bloodstream and release carbon dioxide from the bloodstream back into the air. They also filter out tiny blood clots formed in the veins.
Toxic signals: runny nose, clogged sinuses, frequent sneezing and coughing; trouble breathing or getting enough air.
Contributing factors: cigarette smoke; traffic fumes; certain prescription drugs; recycled indoor air that often includes formaldehyde and volatile organic compounds; mold or mildew.
Daily detox: You’ve heard it before, and you’ll hear it again: If you smoke, quit. Also, consider cutting back on dairy products, which can be mucus-forming, and add a bit of ginger to your diet. “Ginger is a lung tonic,” says Alexander. “Add the fresh root to cooking or a tea.”
Clear clogged nasal passages with a neti pot filled with water and noniodized salt, which you pour into one nostril while you breathe through your mouth (the water irrigates your nasal passage and comes out of your other nostril).
When you’re cleaning around the house, read the labels on household products and be sure you follow their guidelines, especially when the products recommend working in well-ventilated areas. Better yet, make your own cleaning products from nontoxic household ingredients. If you suspect that household mold or mildew might be a problem, take steps to eliminate it from your environment.
Get some vigorous exercise each day. Choose an activity that gets your heart beating and makes your breathing heavier. This will help move out the toxins that settle in your lung tissues.
Functions: The lymphatic system includes organs that are crucial in preventing infection, because they help clear our bodies of waste and foreign cells.
Toxic signals: exhaustion, puffiness, frequent illness and swollen nodes.
Contributing factors: a poor diet with few fruits and veggies; a sedentary lifestyle; toxic elements from pesticides and body-care products.
Daily detox: The slow-moving fluids of the lymphatic system can be stimulated through exercise, says Jamieson. Anything that gets your body moving — whether it’s walking, cycling or lap swimming — will increase the flow of your lymphatic fluid.
Another circulation booster is specialized lymphatic massage, in which practitioners use a light, brisk touch to promote lymph-fluid movement.
Incorporate immunity-boosting foods into your diet, such as carrots, red peppers, cantaloupe and green leafy vegetables. Flavor your foods with cayenne pepper and horseradish, which also help circulate lymphatic fluids.
Try to avoid aluminum-based antiperspirants if you can, says Max Tomlinson, a naturopath and author of Clean Up Your Diet: The Pure Food Program to Cleanse, Energize and Revitalize (Duncan Baird, 2007). “Antiperspirants block a major system of elimination,” he says. “If you’re not sweating, you’re not eliminating.”
Not prone to sweating in the first place? Try saunas and steam rooms, both of which stimulate sweating and lymphatic circulation.
Functions: The body’s largest organ, skin provides a barrier to the external environment, regulates body temperature, and helps moderate blood flow. It also excretes some toxins.
Toxic signals: rashes, acne, clogged pores, flaking.
Contributing factors: toxic, pro-inflammatory diet; irritating personal-care or laundry products; pesticides and industrial residues on clothing; dead-skin buildup; overloaded, toxic organs.
Daily detox: Toxins are both absorbed and eliminated through the skin. So always read product-ingredient labels closely: Legislation for health-and-beauty products claiming to be “natural” or “organic” is practically nonexistent. Ditto with household products. Choose those without added fragrances, perfumes or dyes, and avoid potentially toxic additives such as parabens, phthalates, petroleum products and sodium lauryl/laureth sulfates. Switch to nonirritating, nonfragranced laundry products.
To remove dead skin cells that can clog pores and block elimination through the skin, brush your body firmly for a few minutes before you shower with a skin brush made of soft, natural fibers. Skin brushing also helps stimulate oil-secreting glands that help moisturize skin. If you prefer baths to showers, try adding a cup of baking soda and a cup of Epsom salts to the tub — both are detoxifying.
Vigorous activity is another way to detox your skin. “It’s important to exercise and sweat,” says Elson Haas, MD, coauthor of The New Detox Diet: The Complete Guide for Lifelong Vitality With Recipes, Menus and Detox Plans (Celestial Arts, 2004). “A sauna or steam room can help, too — anything that opens pores helps us sweat out some toxins.”
Finally, consider wearing clothes made of organic cotton, hemp or linen. Our skin absorbs the elements it touches — and the residual pesticides in many fabrics are no exception. (Visit www.organicexchange.com to locate stores that carry natural, organic clothing.)
Take a few daily, modest steps to ease the toxic burden on your body, the experts suggest, and you’re likely to reap large and unexpected dividends. “People typically feel far more energetic and clear-headed once their natural detoxification systems have a chance to catch up,” says Alexander. “It’s also not unusual to see clearer skin and an increase in metabolism.”
And don’t be surprised if a lot of small, nagging health problems seem to clear up on their own. “I think detoxification is one of the key aspects of preventive medicine,” says Haas.
A safe, affordable, preventive health solution that helps our whole body function better? Nothing the least bit yucky about that.
