Re: [CR] Sci/Lay: Two epidemiology PDF available diet studies

I stand corrected, All.

Fig. 1 showed that 3 mg/ml in fish-eating and 11.3 mg/ml in vegetarian were

the levels of leptin in men. For women the respective numbers were 11.8 and

5. So not only was there a large decrease with of leptin with fish, there

was also an reduction of the difference between men and women in leptin

level. This sounds positive considering women outlive men. All were a

relatively low about 20 body mass index.

Cheers, Al.

This seems at odds with the following text you quoted:
