What Is the Raw Food Diet?
Is It Healthy? Should You Try It?
With all the buzz about the harmful effects of additives, chemicals, and processed foods, you might have wondered: what if I just stick to eating natural, unprocessed food?
Enter the raw food diet—a lifestyle that takes “natural” to a whole new level. Advocates of the lifestyle insist it is the healthier option. But is there any truth to that? Perhaps some!
What Is a Raw Food Diet?
Raw food diet, also called raw foodism or raw veganism, is built on the principle of consuming foods in their natural, unprocessed state.
Generally, food is considered raw if it hasn’t been heated above 104–118°F (40–48°C), pasteurized, refined, treated with pesticides, or processed. Because it centers on uncooked plant-based foods, the raw food diet is often considered a form of veganism. However, not everyone follows it the same way.
Some include raw or dried animal products like jerky or unpasteurized dairy, while others are comfortable consuming raw milk and cheeses.
How to Follow the Raw Food Diet
To follow a raw food diet, at least 75% of your meals should consist of raw foods. Since cooking is off the table (literally), you’ll need to get creative with preparation methods like blending, juicing, soaking, sprouting, and dehydrating.
Here’s what you can eat:
Fresh fruits and vegetables
Nuts and seeds
Sprouted grains and legumes
Fermented foods like kimchi or sauerkraut
Cold-pressed oils Fresh herbs and spices
Anything cooked or processed—including baked goods, refined sugars and flours, pasteurized dairy, processed oils, alcohol, and most snack foods are no-nos.
Why Go Raw?
Raw food enthusiasts believe that skipping the stove preserves more of a food’s natural enzymes and nutrients. And yes, it’s true—enzymes, being heat-sensitive proteins, often break down at temperatures above 117°F (47°C).
These enzymes help kickstart the digestive process, breaking down food into nutrients your body can absorb.
Their concern is that cooking destroys these enzymes, forcing the body to work harder and possibly leading to enzyme “burnout.” However, there’s no scientific evidence to support this claim. Your body is fully capable of making all the digestive enzymes it needs.
Another argument raw food supporters make—which does hold water—is that cooking can reduce a food’s nutritional value, especially when it comes to water-soluble vitamins like vitamin C and the B vitamins.
Boiling, for instance, can leach away up to 70% of these nutrients. And the longer the heat exposure, the more nutrients are lost. That said, not all cooking methods are equally harsh. Steaming, roasting, and stir-frying tend to preserve more nutrients than boiling or deep-frying.
Finally, some proponents believe in a “life force” inherent in raw foods—an energy or vitality they claim is lost during cooking. While this idea isn’t backed by science, it’s a core belief among raw food advocates.
Is a Raw Diet Good For You?
There’s no denying the benefits of eating the rainbow—loading up on fruits, vegetables, nuts, and seeds gives your body a wide range of nutrients, fiber, and healthy fats that support everything from digestion to heart health.
You’ll also be cutting out ultra-processed foods, which means less added sugar, trans fats, and sodium in your diet.
The raw food diet can be effective for those looking to lose weight due to its low-calorie nature and high fiber content. Fiber helps you feel full longer, curbing overeating and promoting sustained weight loss.
Unsurprisingly, people who ate plenty of fruits and vegetables had a lower risk of dying from any cause over six years.
Some studies even suggest mental health benefits—like a 2018 study linking raw fruit and vegetable intake to reduced depressive symptoms and higher life satisfaction.
Cons of Raw Food Diet
While there are benefits to eating more raw foods, the diet isn’t without its downsides:
Calorie deficiency: The reduced calorie intake may leave you struggling to meet your daily energy needs—leading to fatigue or unintentional weight loss over time.
Nutrient deficiencies: By avoiding cooked animal products and certain grains or legumes, you could miss out on key nutrients like protein, iron, calcium, vitamin B12, iodine, and vitamin D.
Fewer nutrients: While cooking can reduce some nutrients, it actually boosts others. Lycopene in tomatoes, for example, becomes more absorbable with heat—doubling in content and increasing antioxidant capacity by over 60%. The same goes for carrots, zucchini, and broccoli.
Texture challenges: Uncooked foods are harder to chew and digest than cooked ones, making meals less enjoyable for some people.
Anti-nutrients: Certain plants contain compounds called anti-nutrients that block nutrient absorption. Cooking helps neutralize these compounds.
Reduced antioxidant availability: While cooking reduces some nutrients (like vitamin C), it increases others, making them more bioavailable.
Foodborne illness risks: Eating raw animal products (meat, fish) or contaminated produce increases your risk of exposure to harmful bacteria like Salmonella or E.coli.
Cost: Sourcing fresh organic produce can be expensive—and maintaining variety may require more effort than traditional diets.
Balance Is Key
Going completely raw may not be necessary—or even ideal—for everyone. Instead, prioritizing fresh, whole foods while ensuring you meet your calorie and nutrient needs is a good place to start.
At the end of the day, a balanced diet is the healthiest one.
