If young, healthy adults eat raw carrots or drink fresh carrot juice with a little canola oil, their bodies absorb the beta-carotene quickly—peaking in the blood in just 1.5 hours—and it’s all cleared out within 24 hours.

If healthy young adults eat raw carrots or drink carrot juice with a bit of oil, it boosts their body's β-carotene levels a lot—but that doesn’t actually improve their overall antioxidant power in the blood over the next day.

Drinking carrot juice helps your body absorb more beta-carotene than eating raw carrots. This happens because juicing breaks down the carrot's structure, making it easier for your body to soak up the nutrients.

Juicing carrots might help your body absorb more of the good stuff (like vitamin A) even though the juice has less of it per bite — you just need to drink more of it to get the same amount you'd get from eating whole carrots.

Eating more fruits and vegetables for 3 months makes the level of alpha-carotene—a plant nutrient—in the blood go up by 50% in people who didn’t eat much before.

Scientists made a new way to measure how well kids absorb vitamin A from pumpkin or spinach by testing their poop — no needles needed!
