I bet it will be 50 years before your doctor gets the hospital nutritionist to create a post-stroke diet protocol. Unless you call the hospital president and ask why the stroke department doesn't follow and implement research.

Eating foods rich in amino acids could be as good for your
heart as stopping smoking or getting more exercise – according to new
research from the University of East Anglia (UEA).
A new
study published today reveals that people who eat high levels of
certain amino acids found in meat and plant-based protein have lower
blood pressure and arterial stiffness.
And the magnitude of the
association is similar to those previously reported for lifestyle risk
factors including salt intake, physical activity, alcohol consumption
and smoking.
Researchers investigated the effect of seven amino
acids on cardiovascular health among almost 2,000 women with a healthy
BMI. Data came from TwinsUK – the biggest UK adult twin registry of
12,000 twins which is used to study the genetic and environmental causes
of age related disease.
They studied their diet and compared it to clinical measures of blood pressure and blood vessel thickness and stiffness.
They
found strong evidence that those who consumed the highest amounts of
amino acids had lower measures of blood pressure and arterial stiffness.
But
they found that the food source was important – with a higher intake of
amino acids from plant-based sources associated with lower blood
pressure, and a higher intake from animal sources associated with lower
levels of arterial stiffness.
Lead researcher Dr Amy Jennings,
from UEA’s Norwich Medical School, said: “This research shows a
protective effect of several amino acids on cardiovascular health.
“Increasing
intake from protein-rich foods such as meat, fish, dairy produce,
beans, lentils, broccoli and spinach could be an important and readily
achievable way to reduce people’s risk of cardiovascular disease.
“Results
from previous studies have provided evidence that increased dietary
protein may be associated with lower blood pressure. We wanted to know
whether protein from animal sources or plant-based sources was more
beneficial – so we drilled down and looked at the different amino acids
found in both meat and vegetables.
“We studied seven amino acids -
arginine, cysteine, glutamic acid, glycine, histidine, leucine, and
tyrosine. Glutamic acid, leucine, and tyrosine are found in animal
sources, and a higher intake was associated with lower levels of
arterial stiffness.
“All seven amino acids, and particularly those from plant-based sources, were associated with lower blood pressure.
“The
really surprising thing that we found is that amino acid intake has as
much of an effect on blood pressure as established lifestyle risk
factors such as salt intake, physical activity and alcohol consumption.
For arterial stiffness, the association was similar to the magnitude of
change previously associated with not smoking.
“High blood
pressure is one of the most potent risk factors for developing
cardiovascular disease. A reduction in blood pressure leads to a
reduction in mortality caused by stroke or coronary heart disease – so
changing your diet to include more meat, fish, dairy produce and pulses
could help both prevent and treat the condition.
“Beneficial daily amounts equate to a 75g portion of steak, a 100g salmon fillet or a 500ml glass of skimmed milk,” she added.
Prof
Tim Spector, from the department of Twin Research at King's College
London, said: "The finding that eating certain meat and plant proteins
are linked to healthier blood pressure is an exciting finding. We need
to understand the mechanism to see if it is direct or via our gut
microbes."
'Amino Acid Intake Is Inversely Associated with Arterial Stiffness and Central Blood Pressure in Women’ is published in the September edition of the Journal of Nutrition.
