#WTF Is Clean Eating?
No, it’s not all about making sure those carrots are squeaky clean before chowing down (though that’s probably not a bad idea). While there's no hard and fast definition, clean eating is all about consuming only whole foods (think: fruits, vegetables, and whole grains), while avoiding processed and fast foods at all costs. The idea is to promote health and encourage individuals to become aware of what they are eating (not to mention the benefits of lowering sugar, sodium, and artificial ingredient intake). So what’s the fuss all about, and should you try it, too? Due to the lack of super-strict rules attached to this lifestyle, its popularity may lie in its ability to encourage healthier eating by allowing people to pick the foods they like and reap healthy rewards.
What’s the Deal?
While the term "clean eating" is relatively new, the concept originates from the 1960’s and its (hippy-dippy) health-focused condemnation of diets containing high amounts of processed foods. (Keep in mind not all processed foods are equal: They span a spectrum ranging from minimally processed items like the bag of spinach you get at the grocery, to heavily processed foods like the frozen fish chicken nugget in the back of the freezer.) The closer your foods are to the minimally-processed side, the closer you are to eating clean.
The “rules” of eating clean can vary widely, and it’s important to note that this diet isn’t really about losing or gaining weight — it’s just about eating healthier. While some serious clean eaters choose to forego anything that’s been processed at all — meaning they’ll stick to fresh-picked produce, and will pass on supermarket meats, dairy, and grains. Others choose more lenient plans, focusing on eating only whole foods (even if they’ve undergone some minimal processing), allowing conventional supermarket meat, veggies, and grains (though loaf bread with unrecognizable ingredients is probably off limits).
Why It Matters
The benefits to eating whole foods are plentiful. Research shows that eating fresh fruits and vegetables can aid in the prevention and control of weight gain, which can lead to a host of chronic diseases . Plus, studies suggest a diet rich in these healthy food groups can reduce the risk of cardiovascular disease, cancer, Alzheimer’s, and stroke (to name a few!). The consumption of a variety of whole grains and legumes has been linked to reduced risk of diabetes, too .
And we’re not the only ones on board with upping veggie intake: The US Dietary Guidelines for 2010 (the most recent) encourage eating more fruits, veggies, and whole grains and reducing the amount of sugary beverages like soda and juice.
Adding more vegetables and quinoa to the plate are great, but cutting down on the added salt and sugar is also important to clean eating (and overall health!). Research shows a reduction of dietary salt intake can help delay or prevent hypertension and decrease the chances of cardiovascular related health issues and death . Additionally, 80 percent of trans fats come from processed foods (the other 20 percent take place naturally in meat and dairy products) — yikes! These trans fats increase LDL or “bad” cholesterol levels that are linked to increased cardiovascular related health issues.
Is it Legit?
All signs point to yes (though we’re not saying “all clean, all the time” is definitely the way to go). While it might not be necessary for everyone to eat clean, there don’t seem to be any downsides (other than having to pass on that nitrate-packed chili cheese dog at the ball park). Clean eating is more of a lifestyle than a diet, and its flexibility leave a lot of accountability up to each individual. The key is to being a successful clean eater is eliminating as much processed food as possible. And the great part is that it allows a high level of customization (not a fan of Brussels sprouts? No problem!). As with any change in diet or food consumption, it is always recommended to consult a health care professional (such as your doctor or registered dietitian) who may have suggestions on the best way to get started.
It’s also important to note that allowing yourself a cheat day (or meal, or week-long vacation) every once in a while can actually help you stick to that healthier diet for the long-term. Some research suggest that the occasional cheat day can actually boost metabolism by upping leptin production, which can help the body burn more calories after overeating (at least temporarily). Restricting calories can cause leptin levels (the hormone responsible for maintaining our energy balance and helping with weight loss) to decrease, but temporarily increasing calorie intake can also give a boost to leptin production  . It’s that bump that can briefly increase metabolism (by about 30 percent, for up to 24 hours). Plus, you deserve a little reward on Friday night after a long week of healthy eating!
Want to try eating clean yourself? Making time to prepare meals each day can be tough. To make it easier, some suggest creating shopping lists for the week, month, or season and keep the list simple and manageable. Cooking double batches of a recipe can help save time, and you’ll have healthy leftovers to take to work or school the next day. The extra planning may be worth it for the body and the wallet: Research shows that foods from convenience stores are less healthy and more expensive than a well-budgeted and planned out menu from items purchased in a grocery store .
Introducing whole fruit and veggie smoothies and juices to your breakfast routine, as well as experimenting with new and creative salads and soups for lunch is a great way to eat cleaner each day. Another way to eat cleanly and effectively is to read each food label (including ingredients!) carefully, and to see how many nutrients the food gives you per serving; there’s nothing wrong with being aware of what’s going in that body and how it makes you feel! Plus, reading the ingredient list is often a clear giveaway as to whether a food would be considered “clean” — a long list of unpronounceable and unrecognizable ingredients is a sure giveaway that something’s been over-processed and loaded with not-so-healthy stuff.

Thanks for putting "clean eating" on the radar for your readers!
While your heart is in the right place, in encouraging your audience to include more whole, unprocessed foods in their lifestyles, I think you planted a strange and perhaps undermining idea. To call a bag of spinach "minimally processed" is a bit disingenuous, as you are calling picking, trimming, washing, and packaging a form of "processing." By that standard, even the produce at the farmer's markets is "processed" to some extent, the moment the farmer puts ta item into your bag! That is just a silly way to think about it. To put bagged veggies on the same classification scale as fruit roll-ups and chicken nuggets is just absurd. If you are reading a package label and there are more than 5 ingredients, and/or some of them are unpronounceable, THAT is processed. I would like to think that the American public can tell the difference, but alas, I am not so sure. The major food companies are no stranger to marketing "all natural" and "whole grain goodness," when the actual product is anything but. It is also human nature that we don't want to be told that what we're doing is wrong -- or even that it can be improved. People will go to extremes to justify that what and how they currently eat is somehow good for them.
I think Mark Bittman and Michael Pollan are right on the money in their answer to the question, "How should people eat?" Eat [real] food.. Not too much. Mostly plants.
