Claims that tomato juice is good for the heart not backed by evidence
- dvfjsdhgfv 7y agoI still wonder why anyone is still spending money on studies without a control group, it makes the whole study useless. And it wouldn't be that expensive since you wouldn't even need to give them tomato juice, just measure their cholersterol and blood pressure levels.
- AstralStorm 7y agoSorry, but both kinds of studies are useless. Your proposition is observational and needs a big sample. (Not that any nutritional study does not need one, just an order of magnitude bigger.) Tomato juice is liable to get lost in the noise of various diets and genetics unless you truly control the whole of the diet, which is reasonably easy to do with free, well done boxed meals. Then you just need a sample size of few thousands instead of few hundred thousand.
- dvfjsdhgfv 7y agoYes, I totaly agree, I just wonder why - even if it's observational study - they decided not to have a control group at all. They might as well choose not to have any study at all, the result would be the same.
