What is Clean Eating

Defining Clean Eating

Eating “clean” is gaining traction — but what does it actually mean, and how is it good for the body?

Clean eating is a deceptively simple concept. Rather than revolving around the idea of ingesting more or less of specific things (for instance, fewer calories or more protein), the idea is more about being mindful of the food’s pathway between its origin and your plate. At its simplest, clean eating is about eating whole foods, or “real” foods — those that are un- or minimally processed, refined, and handled, making them as close to their natural form as possible. However, modern food production has become so sophisticated that simply eating whole foods can be a challenging proposition these days.

What Counts as Processed Foods?

First, let’s start with the definition of processed food. “Processing” includes:

  • Additions of any kind — everything from salt, sugar, and fat to aid flavor and mouth feel, to preservatives that keep food from spoiling too quickly, to the vitamins enriching everything from beverages to breakfast cereal.
  • Changing the form of the natural food — for instance, removing the bran and germ from whole grains to create refined bread, mashing apples into applesauce, or stir-frying veggies.
  • Foods with components manufactured in a lab. (You probably don’t need clarification on this one, but if the ingredient list has stuff you can’t recognize or pronounce, that’s a pretty solid indication that it’s not natural).

In that light, processed food includes everything from a hot dog (where do we even begin?) to jarred organic pasta sauce and instant oatmeal. And yes, changing the form of natural food includes cooking as well, so even your steamed broccoli is technically processed, albeit minimally.

So why, exactly, is processing so bad — especially if it’s something as simple as adding heat?

Why Is Processed Food Bad?

In two words: It’s not. Or rather, not categorically.

“Processing is not always bad,” says Jessica Fanzo, assistant professor of nutrition at Columbia University. “Often processing removes toxins or bacteria, or allows for us to eat certain types of foods in off-season due to freezing or canning.” (Pasteurized milk, anyone?) Processing “can also include altering the consistency or taste of food to make it more appealing,” Fanzo adds. So that delicious post-workout kale-celery-spinach-banana smoothie you had? Enjoy that virtuous feeling knowing that you were likely able to down that giant amount of greens because your treat was somewhat processed.

Still, even though pasteurized milk, kale smoothies, and instant oatmeal are all processed, that doesn’t make them on par with doughnuts and Diet Coke.

“The key is to avoid foods that are ‘ultra-processed,'” says Fanzo — basically, anything food-product-like or ready-to-heat.”

The Problem with Ultra-Processed Foods

As you can probably guess, the health problems associated with ultra-processed food are numerous. Foods with genetically modified organisms (GMOs) have been linked to cancer and infertility; highly processed foods are stripped of nutrients needed for overall health; and heavily modified food tends to have additives that overstimulate the production of dopamine, the “pleasure” neurotransmitter, perpetuating a negative cycle of constant junk food cravings.

However, there’s added reason for pause when reaching for the Pop-Tart.

In a 2011 article published in the Journal of the World Public Health Nutrition Association, Carlos Monteiro, professor at the Department of Nutrition of the School of Public Health at the University of Sao Paulo, argues that having ultra-processed foods touted in a way that makes it seem good for you — less sodium! no trans fats! vitamin-enriched! — actually causes more damage to our collective understanding of healthy eating than we may realize. Considering the increasing abundance of “healthfully” enhanced products in the grocery aisles (or perhaps even your refrigerator), Monteiro may be on to something.

The Perks of Clean Eating (now we’re talking)

Thanks to extensive research that has linked eating whole foods with good health, “we do know that largely plant-based diets are healthy,” says Fanzo. Multiple studies have shown that diets heavy on fruits and vegetables can curb or prevent certain life-threatening conditions and diseases, such as high blood pressure, type 2 diabetes, and cardiovascular disease. Plus, there’s research linking diets high in fruits and veggies to healthy weight management and glowing skin and hair — as if you needed more motivation.

How to Eat Clean

Unprocessed foods include:

  • Fresh fruits and vegetables
  • Dried legumes
  • Nuts
  • Farm-fresh eggs

Minimally processed foods include:

  • Unrefined grains, like whole wheat bread and pasta, popcorn, steel-cut oatmeal, quinoa, and brown rice
  • Frozen fruits and vegetables
  • Unprocessed meat; wild over pastured, pastured over grain-fed
  • Hormone-free dairy
  • Oils

Pesticide-free organic food is preferable to avoid consuming added hormones or chemicals. It’s also important to note that eating clean doesn’t give you free reign to eat endless quantities. They may be healthy, but they still have calories!

You always have to think about portion size. I encourage you to think of your plate in terms of: proteins, healthy/clean carbs, and healthy fats. Just go off the picture below:

How to Shop Clean

Realistically, eating clean doesn’t mean you need to eat everything raw and straight from the ground. It means choosing minimally processed foods with few ingredients on the label, if it has a label at all.

If you’re shopping around the perimeter of the grocery store, that’s always a good start.

When perusing the main aisles for packaged foods, ask yourself: Where did this food or its ingredients come from? How much has it been processed or handled? The ingredient label should be short, and all ingredients should be recognizable. Scan for easy-to-avoid additives like artificial coloring and flavors.

How to Cook Clean

Cooking does alter your food, but it isn’t necessarily a bad thing.

“While it’s true that some nutrients are lost during cooking, like vitamin C, other nutrients are increased when foods are cooked, like lycopene, so it’s best to eat a wide variety of foods, in both their raw and cooked forms,” says EA Stewart, RD, who blogs at The Spicy RD.

When cooking food, “the focus should be on maintaining the integrity of what you are consuming and avoiding high-fat cooking methods such as deep-frying or stewing in animal or vegetable fats,” says Miranda Hammer, a New York City registered dietitian and author of food blog The Crunchy Radish.

When cooking, opt for flash-cook methods such as stir-frying and ones without additives like steaming. For fruits and veggies, raw is best, but steaming is a close second in terms of preserving nutritional value and keeping the food’s natural integrity.
