A new study, published in The Journal of Nutrition, suggests that extreme dietary habits involving carbohydrates and fats affect life expectancy. Researchers from Nagoya University Graduate School of Medicine in Japan led by Dr. Takashi Tamura found that a low carbohydrate intake in men and a high carbohydrate intake in women are associated with a higher risk of all-cause and cancer-related mortality and that women with higher fat intake may have a lower risk of all-cause mortality.
34,893 men and 46,440 women … 2783 deaths (1838 men and 945 women)
30% more women in the study but only half as many deaths? That doesn’t make any sense. There’s something very wrong with the sample or the follow-up or both.
Plus all the variables in the lifestyle associated with different diets. Diet soda probably doesn’t actually cause weight gain, but people turning to diet soda probably eat poorly already. This also only seems to show food intake percentages but not the total calorie intake. So do the high carb eaters just eat one potato per day? And the high fat eaters 6lbs of pork? This a multi dimensional problem needing more data to find the real trend. I mean, people with gun permits have a higher chance to be shot by a gun. Is it because the permit shoots the? Or is it because permit holders are more likely to be in a place where guns are more common?

It doesn’t seem conclusive… Just adds to the noise it purports to address.
It’s paywalled and sci-hub doesn’t have it.
There’s something very weird about the numbers:
