What Not to Eat to Prevent a Stroke

 "What Not to Eat to Prevent a Stroke"

The large majority of the available evidence
is in favor of a protective association between
fruit and vegetable consumption and the risk of stroke.
The worst foods appear to be meat and soda.
Eating, like, a burger for lunch and a pork chop for dinner,
two breakfast sausage links, and a typical 20-ounce bottle of soda
may increase stroke risk by 60%.
Reviewers suggest the meat effect may be the saturated fat or cholesterol,
the iron-mediated oxidized fat or the salt but it could also be the TMAO.
The carnitine in meat and the choline in dairy, seafood,
and especially eggs are converted by our gut bacteria
into trimethylamine, which is oxidized by our liver to TMAO,
which may then contribute to heart attacks, stroke, and death.
And indeed, in a 2019 study published in the journal of
the American Medical Association following tens of thousands of Americans
for a median of about 17 years up to a maximum of 31 years
found that “higher consumption of dietary cholesterol or eggs
was significantly associated with a higher risk of incident
cardiovascular disease and all-cause mortality, in a dose-response manner.”
Meaning those who ate more eggs or consumed more cholesterol in general
appeared to live significantly shorter lives on average
and the more eggs the worse it was,
and this includes egg consumption and stroke.
But that’s not what a meta-analysis funded by the egg industry found.
It turns out such meta-analyses have evidently been flawed
by major methodological drawbacks; so, to eat or not to eat?
It would seem moderation of egg consumption is called for,
along with other sources of dietary cholesterol,
given the new study data, which had the advantage of a
“longer follow-up than the majority of the previous studies
and may [therefore] have provided more power to detect associations.”
Similarly, with meta-analyses of dairy, no apparent link emerged,
but evidence of publication bias was found,
meaning there appeared to be missing studies,
potentially shelved by industry-funded researchers
for not showing funder-friendly effects.
Researchers studying the relationship between funding
sources and conclusions in studies of sugary drinks and milk
found that studies funded by the likes of Coca Cola
and the dairy council had over seven times the likelihood
of coming to founder-friendly conclusions than independent research,
which is twice as bad as drug companies.
Big pharma only seems to be able to get away with a three-fold bias.
Of particular interest, not a single one of the interventional studies
looking at soda or milk ended up with an unfavorable conclusion.
The bottom line is that yes, dairy fat may be better
than other animal fats, such as those found in meat,
but something like whole grains would be better still,
though swapping dairy out for refined grains or
added sugar wouldn’t be doing you any favors.
When it comes to stroke risk, vegetable fat is better than dairy fat,
meat fat is the worst, whole grains are better,
and fish fat, added sugars, or refined grains are statistically about the same.
In terms of dietary patterns and stroke, most of the studies on plant-based
dietary patterns have found a protective effect against stroke,
whereas those looking at westernized patterns,
those based more on animal foods and added sugars and fats,
found a detrimental effect on adherence to westernized patterns.
African Americans are five times as likely to die from stroke in middle age,
a black-white disparity largely driven by the fact that
they’re just having so many more strokes.
In this population, a Southern-style diet, characterized by a lot of fried foods
and meat may be playing a role in increasing the risk of stroke,
whereas adherence to more plant-based diets may reduce stroke risk.
Yes, wrote the director of the Stroke Prevention
& Atherosclerosis Research Centre,
“learning to make vegetarian meals every other day is a tall order
for most North Americans, but is feasible given
tasty recipes and a positive attitude.”
