Is clean eating good for runners?

"I've started eating clean; quinoa and brown rice. No more white rice."
"I haven't had cookies for ages. I'm eating clean - no added sugar."
"When I visit my parents, I bring my own food. It's healthier."

The "clean eating" movement has raised a lot of questions about what you should and should not be eating. I hear athletes chatter a lot about "good" (nutrient dense) foods, "bad" (nutrient poor) foods, and "clean" foods. Hence, if you are feeling confused about what's best for you to eat for health and performance, you are not alone.

Clean foods are generally defined as being unprocessed, all-natural, free of GMOs, added sugar, high fructose corn syrup, refined grains, and perhaps gluten. Clean foods are also free of antibiotics, hard-to-pronounce ingredients, and wrappers. Some athletes talk about avoiding un-clean food with an air of superiority: "I don't do sugar or white flour anymore." This often includes denying themselves of some fun and special foods (birthday cake, dessert with friends, warm dinner rolls). Clean eaters can easily instill guilt in a friend or relative who eats, let's say, warm rolls from the restaurant's breadbasket, as if that person is sinning. (Note: Eating is not a sin!)

Please understand there is no such thing as a good, bad, clean, un-clean, or junk food. An apple, for example, is commonly considered to be a good, clean (health-promoting) food, but a diet of all apples is a bad diet.

I encourage you to stop labeling specific foods (white bread, red meat) or ingredients (sugar, salt) as being good or bad. Instead, you want to look at how the food fits into your sports menu for the entire week, month, and year, and evaluate a food in context of a balanced or unbalanced diet. Even so-called bad foods with little nutritional value can be balanced into an overall wholesome sports diet. (Note: the only bad foods - that you really don't want to eat - are moldy, poisonous, or cause an allergic reaction.)

The dirt on clean eating

Clean eating often comes with unintended consequences. Please keep the following dirt in mind if you have stopped eating salt, red meat, refined grains, and added sugar:

• Eliminating table salt when cooking and at the dinner table reduces your intake of iodine. This mineral was added to table salt in the 1920s to eradicate goiter (a thyroid disorder). Iodine is in dairy milk, saltwater fish, and seaweed. If you rarely eat those items, and add no salt to your food, your iodine intake could be quite low. Iodine deficiency is associated with infertility, poor brain development in infants, low metabolism, and chronic fatigue syndrome. Pink Himalayan salt, sea salt, or other specialty salts are not iodized. Nor is the salt used in commercial foods. If you are an athlete who sweats heavily and craves salt, don't hesitate to enjoy a sprinkling of iodized salt.


• Cutting out red meat reduces your intake of iron, a mineral needed to prevent anemia and needless fatigue. Anemia is prevalent among females who lose iron via menstrual bleeding. Studies suggest 20% to 50% of collegiate female athletes experience anemia. Male athletes are also not immune from becoming anemic. A study with collegiate male runners suggests about 20% were iron-deficient. If you choose to abstain from eating iron-rich red meat, be sure to consume alternate sources of iron, such as chicken thighs, tuna fish, dried beans, and iron-enriched breakfast cereals. Note that all natural cereals, like granola, have no additives. That means, they have no added iron. For people who eat no red meat, this further reduces their chances of consuming adequate iron.


• Eliminating enriched white bread and other refined grains also reduces the intake of iron, as well as B-vitamins such as folic acid. These nutrients are added to help prevent deficiencies. Folic acid is of particular importance for women who might become pregnant; it helps reduce the risk of birth defects. A diet with some enriched and fortified refined grain foods boosts intake of this important nutrient. For example, US Dietary Guidelines recommend half of the grains you eat should be whole grains, the other half can be enriched grains. Yes, white pasta and breads do offer nutritional value! Mix 'n' match your grains.


• Eliminating "carbs" (starchy foods, such as bread, pasta, rice, etc.) can easily lead to "dead legs" and poorly fueled muscles. Far too many athletes who train hard eat just protein and veggies for dinner, with no "carby foods." Even athletes who eat a lot of veggies with a meal will unlikely consume the recommended 3 to 5 grams of carbohydrate per pound of body weight that optimally replenishes the muscle glycogen stores of competitive athletes. This comes to at least 1,200 calories of carbohydrate a day for the 150-pound athlete who exercises 1 to 2 hours a day. This is far more carbs than found in a large salad doused with 500 calories of dressing! No wonder I hear so many complaints about fatigue, dead legs, and poor workouts from athletes who have "knocked off the carbs." Eating a grain food as the foundation of each meal resolves the problem.


• Eliminating foods with added sugar eliminates a lot of (fun) foods. Do you really want to never enjoy cookies or birthday cake ever again - without feeling guilty, that is? Is something wrong with enjoying a sweet treat in moderation? No! For example, US Dietary Guidelines state 10% of total calories can come from refined sugar. For most athletes, that's 200 to 300 calories of added sugar a day (50-75 g) that helps fuel muscles. Athletes who avoid sugar (with hopes of curbing their so-called sugar "addiction") commonly end up binge-eating sugary foods. Denying sugar is not the solution. Rather, routinely balancing in a sweet such as a daily cookie, can help keep cookies from become an all-or-nothing food.

The bottom line - Instead of aspiring to eat clean, how about focusing on eating a variety of foods that offer 85% to 90% quality calories? Balance in unclean foods, if desired, with the remaining 10-15% of your calories. No need to suffer through a perfectly clean sports diet, because an excellent diet is good enough. Despite popular belief, a little bit of "dirty food" will not ruin your health forever.
