The other reason I was wary of carrot juice is that I thought it only provided beta carotene. This is because everything you read about carrots talks about beta carotene. I though other vegetables would be better as the have a larger mix of carotenoids.
However it turns out that carrots have more in them than beta carotene. They have:
- Lutein and Zeaxanthin. It is only a very small amount, but still measurable and worthwhile to have
- Alpha carotene. It have very high levels of alpha carotene, about half the level of beta carotene.
- Beta carotene. Carrots have almost double the level of other vegetables.
PS Beetroot wasn't analyzed in this study, so can't tell if beetroot is better! When I find out I will post.
