Meta-analysis: Fruits, not vegetables, lower triglycerides

Don't make the mistake of assuming this is a health blog when you see two health posts in a row.  I do have the goal of reporting the results of new, interesting meta-analyses. If you focus on one study, you can find whatever results you'd like, but dozens of studies, especially large, random clinical trials? That's more convincing. Facebook should give me a fantastic reputation score. No Fake News here.

This new meta-analysis is not great, but its five cross-sectional and two intervention studies are worth mentioning. Both types of studies find that greater intake of vegetables does not lower triglycerides--the major form of fat stored by the body, which my doctor keeps telling me is way high in my blood. (Turns out, I have a bad gene.)

On the other hand, the more servings of fruit you eat per day, the lower your triglycerides. Two trials is not nearly enough, but, still, the results are interesting.

The authors do not have much of an explanation of how fruit helps, but they do describe an animal trial that found that high fruit fiber intake lowered triglyceride levels in the following order: pomegranate > apple > strawberry > guava > papaya > mandarin and orange.

  1. So, fruit has more sugars/carbs in it. Insulin will rise higher than it would via vegetables. So whatever triglycerides are in your blood stream will be put back into the fat cells.

    I really don't get it. Why even do the study? Do they actually not know this stuff? And if they don't, why are they in charge? It become obvious most research is politically organized rather than having anything to do with, well, research.
