Plant-based diets are best… or are they?

WFPB vegan diets (especially those with no oil) are not the same as vegetarian or pescatarian diets (or vegans who eat potato chips and Oreos). Please stop lumping them together and please stop using “plant-based” if it’s not plant-based
What is also ignored in diet studies is how people ‘feel’, what degree of energy people have on each diet, the longevity of those on each diet, and number of doctor visits on each diet.
Seems like high blood pressure is correlated directly to hemorrhagic stroke. What possible physiological explanation can link vegetarian or vegan diets? One article mentions possible lack of B12 .
The mechanism is unlikely to be related to high blood pressure but this study did not assess mechanisms to explain the findings. Here’s what the authors say: “Future work should include further measurements of circulating levels of cholesterol subfractions, vitamin B12, amino acids, and fatty acids in the cohort to identify which factors might mediate the observed associations.”
And, yes, this study did not have large enough numbers of study subjects to separate out effects for vegetarians vs. vegans.
There is no data on vegans…
Also, a plant-based diet is strictly vegan, not vegetarian, pescatarian or any other variation.
This is why VEGAN is the way to go, wins across the board 💚
