Is it better to eat our vegetables raw or cooked?

0:10.0

If you're thinking raw, you're right.

0:12.0

But if you guessed cooked, you're also right.

0:14.0

A number of nutrients like vitamin C are partially destroyed by cooking.

0:19.0

On the other hand, some nutrients like lycopene and tomatoes

0:22.1

become more absorbable upon cooking. So I advocate eating a combination of cooked and raw foods.

0:29.0

Check out this study on long-term raw foodists. The study was done in Europe, so the average

0:33.4

Western diet here wasn't terrible. About four servings of fruits and vegetables a day,

0:38.6

versus a better so-called wholesome nutrition diet of seven daily servings of fruits and veggies,

0:44.5

both raw and cooked, versus a raw food diet in which they ate, on average, a whopping 17

0:50.7

0:59.1

But that's intake.

1:00.1

How much of it actually got into their bloodstreams?

1:03.5

Blood beta-carotene is considered to be a surrogate marker for fruit and vegetable consumption.

1:08.4

Some researchers even suggest if you tell them what your blood

1:11.1

beta-carotene level is, they can tell you what your health risk is. So who had the most

1:16.6

beta-carotene in their bodies? Those eating four servings a day, seven, or 17. It was the middle

1:23.4

group, the seven daily servings group, because cooking can boost the absorption of

1:28.4

phytonutrients like beta-carotene. For example, you get more beta-carotene in your bloodstream

1:34.0

eating cooked carrots than you do eating the same amount of raw carrots. The raw foodists were

1:39.1

eating 17 servings a day and basically had the same amount of this phytonutrient reaching their internal organs as those of the standard diet getting four measly daily servings a day and basically had the same amount of this phytonutrient reaching their internal organs
