Lycopene Benefits: Raw vs. Cooked Tomatoes
4.7/5 - (16 votes)
Other studies just out show the same phenomenon. Roasted almonds healthier than raw. The cholesterol-lowering effect of all sorts of good veggies improved by cooking. This new study found that long-term raw foodists had low levels of the phytonutrient lycopene, compared to the general population. Lycopene is the wonderful cancer-fighting red pigment in tomatoes. Well, cooked tomatoes provide four times more lycopene than raw tomatoes.
And, cancer prevention is just the beginning. Tomato juice can lower our bad cholesterol 13%. Can successfully treat seasonal allergies, and may even help treat asthma. Treating asthma with tomato sauce. But, when we eat tomatoes raw, we’re losing 75% down the drain.
Raw foods are not necessarily healthier. My recommendation is to prepare vegetables in whichever way will get you to eat the most of them.

UPDATE: Note there are some relatively high fat and protein plant foods such as nuts and soy products; so, I no longer recommend toasting nuts and would steer clear of roasted tofu.
