Banana Blood Pressure:
to Lower Your Blood Pressure? Try Bananas
shortage joins sodium excess as a top risk factor for high blood pressure
heard that eating excess sodium can raise blood pressure, especially in genetically
new findings suggest that getting too little potassium exerts equally unhealthful
effect pressure-raising effects.
bananas are one of the best sources of this elemental nutrient, it makes sense
to emulate our primate friends.
news comes from research presented at the American Society of Nephrology's 41st
Annual Meeting in Philadelphia (Hedayati S et al. 2008).
has been a lot of publicity about lowering salt or sodium in the diet in order
to lower blood pressure, but not enough on increasing dietary potassium.
the negative impact of low potassium intake appears especially strong among African
analyzed data collected from about 3,300 people - about half of whom were African
American - participating in the Dallas Heart Study.
results showed that the amount of potassium in urine samples was strongly related
to blood pressure. People whose reported diets were low in potassium also showed
lower potassium levels in their urine and higher blood pressure.
this effect was even stronger than the effect of sodium on blood pressure.
relationship between low potassium and high blood pressure remained significant
even when age, race, and other cardiovascular risk factors - including high cholesterol,
diabetes, and smoking - were taken into account.
support prior indications and adds a genetic factor Previous studies, including
the large Dietary Approaches to Stop Hypertension (DASH) study, have linked potassium
deficiency to high blood pressure.
new results support this conclusion, and provide important new data on the relationship
between potassium and blood pressure in a sample that was 50 percent African American.
study included a high percentage of African-Americans, who are known to consume
the lowest amounts of potassium in the diet.
authors of the study also identified a possible genetic factor in potassium's
effects on blood pressure.
research led by co-author Chou-Long Huang, M.D. found evidence that a specific
gene called WNK1 may govern dietary potassium's effects on blood pressure.
conclusions are limited by the fact that people in the Dallas Heart Study weren't
following any specific diet.
researchers are currently performing a study in which the activity of the WNK1
gene is measured in participants consuming diets containing fixed amounts of fixed
potassium, to see if WNK1 is responsible for the potassium-pressure link.
Dallas team urged people to get more potassium and less sodium.
foods include bananas, citrus fruits, and vegetables.
consider organic whole foods from both plant and animal kingdoms
to be a major key to superior health. We also think it's terribly
important to eat fish at least twice a week to get the essential
fatty acids. Here at our house, we only eat wild Alaskan salmon
and other wild seafoods from our friends at Vital Choice. Click
