This is a calm, evidence-aware blog about what heat really does to your food. Where raw wins, we say so. Where cooking makes nutrients easier to absorb, we say that too — no enzyme myths, no miracle claims.
No products · Just the evidence
"Raw is always healthier" is a slogan, not a finding. The truth is more interesting and more useful.
Raw Food Facts is a plain-English blog about a question people argue past each other on: does eating food raw keep more of the good stuff in it? Sometimes yes. Heat can degrade vitamin C and some water-soluble vitamins, and a crisp raw salad is a genuinely good thing. But heat can also break down cell walls and free up nutrients your body couldn't otherwise reach — cooked tomatoes and carrots are the classic examples.
We read the research the way a curious skeptic would: fair to the claims, quick to ask for evidence, honest when the answer is "it depends." No supplements to sell, no cleanses, no promises about curing anything.
Our standing rule: we won't repeat a nutrition claim just because it sounds wholesome. If the "enzyme theory" deserves a skeptical read, it gets one.
Heat is not a villain and not a hero. It quietly trades one thing for another — losing a little vitamin C here, unlocking more lycopene or beta-carotene there. Once you see the trade, the raw-versus-cooked argument mostly dissolves.

No invented numbers — just the direction the evidence points, nutrient by nutrient. Most whole foods sit somewhere in the middle, which is exactly the point.
Bioavailability rises when cell walls break down
Water-soluble and heat-sensitive compounds fade with cooking
Raw-food thinking often stops at "cooking destroys nutrients." Here are the situations where a little heat clearly does more good than harm.
Lycopene and beta-carotene are trapped in tough plant structures. Heat breaks those walls down so the pigments — and their benefits — can actually be absorbed. A cooked tomato genuinely delivers more usable lycopene than a raw one.
Some raw foods — certain beans and grains, for instance — contain compounds that block mineral absorption or irritate digestion. Cooking reduces many of them. Here, "raw and natural" is not the safer or more nourishing choice.
Heat isn't only about nutrients. Cooking reliably reduces harmful microbes that raw preparation can leave behind. For eggs, most meats, and certain sprouts, that safety margin outweighs any small nutrient loss.
The best diet is the one you actually eat. If lightly roasting vegetables means you finish a full plate instead of picking at raw ones, the modest nutrient trade-off is easily worth it. Absorbed nutrition beats theoretical nutrition.
Sometimes, sometimes the reverse. Raw preserves heat-sensitive vitamins like C and folate, while cooking makes nutrients such as lycopene and beta-carotene far easier to absorb and improves the digestibility of some foods. The honest answer is that it depends on the food and the nutrient — which is exactly what most of this blog is about.
This is the "enzyme theory," and it doesn't hold up well. Plant enzymes are largely broken down by stomach acid before they can do anything useful, and your body makes its own digestive enzymes regardless. Raw food has real merits, but "food enzymes doing your digesting" isn't one of the strong ones. We look at this claim closely in a dedicated article.
Because "destroys vitamins" is only part of the story. Cooking loses some nutrients while unlocking others, kills harmful microbes, reduces certain anti-nutrients, and makes food more digestible and often more appetising. Losing a little vitamin C to gain more absorbable lycopene, safety, and a plate you'll actually finish is usually a good trade.
As a rule of thumb: shorter times, less water, lower temperatures. Steaming and quick sautéing tend to preserve more than long boiling, which leaches water-soluble vitamins into water you often throw away. If you do boil, keeping the liquid for a soup saves much of what leached out.
No. It's general nutrition information for curious readers. It isn't a substitute for advice from a doctor or registered dietitian, and it doesn't diagnose or treat anything. If you have a health condition, an eating disorder history, or specific dietary needs, talk to a qualified professional before making big changes.
