Raw vs. Cooked: What Actually Matters for Your Energy and Gut Health
Turns out vegetables have opinions about how they’re prepared.
When I got my nutrition certification back in 2011, I went in thinking I already knew the basics. Eat more vegetables, choose whole foods, avoid the stuff that comes in crinkly packaging. Easy peasy. What I didn’t expect was how much was sitting underneath what seemed like simple advice, and the raw vs. cooked question is a good example of that.
Short answer: it depends on the food, but once you know which direction it tilts, you can use that information without overthinking it.
The nutrients that do better raw
Vitamin C and the B vitamins are water-soluble, which works against them in two ways when you cook them. Heat degrades them, and water dissolves whatever is left, so boiling vegetables can strip out anywhere from 15 to over 50% of these nutrients, and even steaming takes some. Raw spinach has roughly three times the vitamin C of cooked spinach if you want a number to hold onto, but we’ll get to spinach in a second because it deserves its own little moment.
The practical fix is simple: eat these foods raw when you can, and when you do cook them, keep it quick. A fast steam beats a long boil, and save the cooking water if you can. The vitamins that leached out are still in there, so pour it into your next soup or sauce rather than tipping it down the drain.
One thing worth knowing, especially if your digestion has been off: if your gut is already inflamed or irritated, raw vegetables can actually make things worse. I noticed this myself whenever I’m sick or my stomach is being difficult, and it’s something I learned the hard way when I put my whole family on a gut-healing protocol that was essentially soup and boiled meat and vegetables for two straight weeks. Not our most exciting dinner table era, but the principle was sound. Cooked food is gentler when your gut is in recovery mode, and your body can absorb more from it, even if the raw version technically has more nutrients on paper.
The nutrients that do better cooked
Beta-carotene is the main one here. It’s the pre-vitamin A compound found in your orange and red vegetables like carrots, tomatoes, and sweet potatoes. Cooking breaks down the cell walls and makes it far more available to your body, and one study found that absorption was 6.5 times greater in stir-fried carrots than raw ones. Add a good fat like butter, ghee, or avocado oil and you’ll absorb even more, so don’t be shy with it.
And then there’s spinach, which earns its own category
Spinach is good for you both ways, and I’m not saying that just to get everyone to eat more of it, although I would be thrilled if that happened. Raw spinach gives you more vitamin C and B vitamins, but cooked spinach gives your body better access to the beta-carotene and iron, and it reduces down so dramatically that you can eat a truly impressive amount of it without really trying. I eat spinach pretty much every day in some form: in my eggs in the morning, sautéed with other vegetables for dinner, thrown raw into a smoothie or a salad or onto a sandwich. There’s no wrong answer here, so just eat it however it appeals to you and feel good about it.
One small tip before you go: squeeze lemon over your cooked spinach, because the vitamin C in the lemon helps your body absorb the iron. Two things working together, and it adds about three seconds to your evening.
The actual bottom line
Eat a variety of vegetables, raw and cooked, and try not to stress about getting the ratio perfect. If your energy has been consistently low, cooking method is a much smaller piece of the puzzle than most people think.
