Raw foods may be richer in certain nutrients than cooked foods. Some nutrients are easily deactivated or can leach out of food during the cooking process. Water-soluble vitamins, such as vitamin C and the B vitamins, are particularly susceptible to being lost during cooking ( 6 , 7 , 8 , 9, 10 ).
Why raw vegetables are better than cooked?
Eating raw vegetables provides your body with optimal levels of folate and water soluble vitamins such as vitamin C. Yet the nutrients in cooked vegetables are actually easier to digest and absorb. The softened fibers of cooked vegetables leads to the release of vitamins E and K, and better mineral absorption.
Why are fresh vegetables more nutritious than cooked vegetables?
Cooked carrots, spinach, mushrooms, asparagus, cabbage, peppers and many other vegetables also supply more antioxidants, such as carotenoids and ferulic acid, to the body than they do when raw, Liu says. The antioxidants in the oil and the vegetables get used up during frying in stabilizing the cycle of oxidation.
Why do vegetables lose nutrients when cooked?
She explained that water-soluble nutrients , like vitamin C, B vitamins or folate, can leach out of veggies when cooked in water. “That’s usually related to the vitamins that have been lost in the water. So, if you’re over-boiling them, then you will lose some of the nutrients.”Jun 7, 2018.
Why are raw vegetables more nutritious for us?

Chapman Family Cancer Wellness at Piedmont, says incorporating raw foods, specifically vegetables and fruits, into your diet can have numerous health benefits.
Are cooked vegetables less nutritious?
Many people think raw vegetables are more nutritious than cooked, but that’s not the case. Cooking vegetables breaks down the plants’ cell walls, releasing more of the nutrients bound to those cell walls. Cooked vegetables supply more antioxidants, including beta-carotene, lutein and lycopene, than they do when raw.
Why are cooked carrots better than raw?
Carrots. Carrots provide more antioxidants when boiled or steamed than when eaten raw, according to a January 2008 report in the Journal of Agricultural and Food Chemistry. In fact, researchers found that boiling carrots until tender increased the concentration of carotenoids by 14 percent.
Is raw broccoli more nutritious than cooked?
Actually, raw broccoli is not necessarily more healthful than cooked. Broccoli is part of the cruciferous vegetable family and great food to include in your diet either raw or lightly cooked. These vegetables provide many nutrients but their unique contribution is a group of compounds called glucosinolates.
Are vegetables more nutritious raw or cooked?
Raw food is not any healthier than cooked food. Cooking decreases some nutrients, yet increases others. It also destroys certain harmful compounds and kills bacteria.
Do raw vegetables have more fiber than cooked?
While cooked vegetables can grant us access to more nutrients, raw vegetables offer more fibre, which Hall explains helps maintain healthy digestion, lower cholesterol and control blood sugar levels.
What happens during cooking that affects the texture of vegetables?
Cellulose and pectin are the fibers that give vegetables their shape and firmness. Cooking softens these fibers. The amount of fiber varies with different vegetables, with the age of vegetables, and even within the same vegetable. A longer cooking time means softer vegetables.
How does cooking affect the nutrients in food?
Heat diminishes vitamins and phytonutrients (beneficial plant compounds other than vitamins or minerals) in fruits and vegetables. The longer they cook, and the higher the temperature, the greater the nutrient destruction. Even chopping food can begin to erode some of the nutrients.
What happens if you only eat raw vegetables?
Apart from essential macronutrients, fruits and vegetables lack other important nutrients like calcium, zinc, and omega-3 and omega-6 fats. Since raw foods are high in fiber, such a diet might lead to a fiber overdose, that might lead to gas or bloating.
Does cooking greens reduce nutrients?
Answer: No, you don’t need to forgo roasted veggies because of high heat. The fact is that all forms of cooking can destroy some of the nutrients (such as vitamin C and B vitamins) in vegetables. Mushrooms, asparagus and cabbage supply more antioxidant compounds when cooked compared with raw.
Which vegetables are healthier raw?

Does cooking broccoli destroy nutrients?
Most of the minerals in broccoli are retained during cooking because they stand up to heat and water better than vitamins. If you steam, stir-fry or roast your broccoli, you’ll get 100 percent of its minerals, according to the USDA. When broccoli is boiled, it loses 5 percent to 10 percent of the total minerals.
How do vegetables retain nutrients?
To retain these vitamins, cook vegetables in as little water as possible for a minimal amount of time (unless you’re planning to consume the water, as in a soup). Steaming and microwaving, both of which use little water, will give you the same results as boiling or blanching but with much less nutrient loss.
