What Happens to Your Body When You Give Up Processed Food

Everyone has heard the phrase "processed foods" by now, but many people don't really know what life would be like without them. Here's a hint: Your health, mood, and appearance will improve—dramatically!

Processed foods are chemical-laden, highly-addictive foods that are carefully curated to appeal to your taste buds—even if it means causing havoc to your health. "These foods are so hard to say no to because they are loaded with added sugars and fats, which physically change how they feel inside the mouth," explains registered dietitian nutritionist Lauren Minchen MPH, RDN, CDN. "The altered texture and taste actually make the body crave more of it."

What's even scarier is that something called "ultra-processed food" exists, which is like the worst of the worst. According to a study published in BMJ Open, these kinds of products make up almost 60 percent of our daily calories and 90 percent of the added sugar we consume.

Here's the final kicker, though: When your diet contains more processed than unprocessed foods, ultimately, you can deprive yourself of the nutrients your body needs. Processed foods are often stripped or void of nutrients, so they tend to be lower in the health-promoting nutrients unique to whole foods, like antioxidants.

From weight loss to migraine relief, here are some of the serious health benefits you can reap if you give up processed foods. Read on, and for more on how to eat healthy, don't miss 7 Healthiest Foods to Eat Right Now.

"A lot of the processed foods are actually triggers for migraines."

Saturated fats make you foggy, sugar and syrups cause crazy energy crashes; the list goes on and on.

"Better skin is one of the major benefits of forgoing processed foods," says Smith. "A lot of the preservatives and ingredients found in processed foods can often get in the way of clear, healthy skin."

Okay, you won't actually be able to stop the clock. But by trading in all the high-fructose corn syrup, additives, artificial colors, and other sketchy ingredients, you'll at least get out of the fast lane toward feeling and looking older than you are. Specifically, a 2019 study found that higher consumption of ultra-processed foods (more than 4 servings daily) was associated with a 62% increased risk of all-cause mortality.

As mentioned earlier, most processed foods have been formulated and designed to taste as appealing as possible and get you addicted to them in the process.

Researchers have found that eating a diet that is high in sugar, saturated fat, and processed carbohydrates can disrupt your sleep, according to the Journal of the American Heart Association. There are many ways in which a processed food-heavy diet can disrupt sleep, but one way is that the added sugar in many products can keep you wired by spiking blood sugar and making it difficult to wind down for the night or causing you to wake up.

From birth control meds to the natural aging process, there are already enough things out there messing with our hormones. When you ditch processed food, it can dramatically help you feel more balanced. While saturated and trans fats should be avoided, regular inclusion of healthy monounsaturated fats can help balance hormones—specifically the appetite-suppressing hormone leptin. According to research published in the British Journal of Nutrition, consuming too many calories from fat and simple sugars can disrupt the proper functioning of the hormones leptin and ghrelin, which can get in the way of your body's ability to regulate weight and metabolism.

15

You'll boost your immune system

"Eating too many processed foods hurts our ability to fight colds because you're not getting enough nutrition to fuel the immune system," says Smith. Most fruits and vegetables are chock-full of immune-boosting vitamins and probiotics, which your body requires to build up its defense system.
