Soy Isoflavones Again Linked to Blood Pressure Benefits

Soy Isoflavones Again Linked to Blood Pressure Benefits
April 2012

Daily consumption of products containing soy isoflavones could help to significantly reduce blood pressure across the general population, according to a new study.

The researchers also found that isoflavones may be of particular benefit for black American adults, nearly 42% of whom are estimated to have high blood pressure, also known as hypertension.

The study reports that consumption of the soy compound could lead to as much as a 10 mmHg drop in systolic blood pressure for people with slightly raised blood pressures—known as pre-hypertension.

The research, presented at the American College of Cardiology’s 61st Annual Scientific Session, compared blood pressure levels of people consuming various levels of the soy compound, finding that those who received less than 0.33 mg of isoflavones per day had significantly higher blood pressure levels than those with the highest isoflavone intake (of more than 2.5 mg per day).

"What’s unique about this study is that the results are very applicable to the general population. Our results strongly suggest a blood pressure benefit for moderate amounts of dietary isoflavone intake in young black and white adults," said Safiya Richardson, of Columbia University’s College of Physicians and Surgeons, who led the study.

"Our study is [also] the first to show a benefit in African Americans, who have a higher incidence of high blood pressure, with an earlier onset and more severe end-organ damage."

"This could mean that consuming soy protein…could lead to as much as a 10 mmHg drop in systolic blood pressure for pre-hypertensives, greatly improving their chances of not progressing to hypertension," said Richardson.

She added that any dietary or lifestyle modification people can easily make, which does not require daily medication is "exciting."

Richardson and her team analyzed data from the Coronary Artery Risk Development in Young Adults (CARDIA) study—an NIH-funded study created to examine the development and determinants of cardiovascular disease.

The study began in 1985 with 5,115 African Americans and white Americans aged 18-30 years old who have been followed and re-examined at various intervals. Year 20 was the first year that participants completed an extensive dietary survey.

They used multivariable linear regression models to evaluate the relationship between daily isoflavones intake and systolic blood pressure after dividing patients across quartiles according to self-reported isoflavone intake.

Richardson noted that even after controlling for age, sex, BMI, smoking, alcohol, physical activity and total caloric intake, the relationship between daily isoflavones and lower systolic blood pressure remained. She explained that as a result, the study helps to lay groundwork for future randomized controlled trials in order to help better understand the association between isoflavones and blood pressure.

Sorry to revive this a bit old thread, but I was just reading about blood pressure lowering foods and come across this thread.
Additional foods that also lower blood pressure (see which values are considered normal on this blood pressure chart) are:
Raisins
If you suffer from hypertension, have raisins stirred into your morning cereals. Combine raisins with nuts. For best results eat a handful of raisins three times a day.
Bananas
Eating foods that are rich in potassium can affect your blood pressure level. An ideal example of food that contains a lot of potassium and is not too expensive is a banana.
Watermelons
Consuming watermelons will improve the health of your heart. This healthy fruit contains a special amino acid which lowers blood pressure.
Tofu
Not only tofu, but eating all soy products can help people who struggle with elevated blood pressure as soy contains an ingredient called isoflavone which may help to lower blood pressure. Green tea also contains isoflavone.
Chocolate
Not expected to be on this list, but chocolate contains flavone, which may help to lower blood pressure. Do not buy a classic chocolate, but rather purchase a chocolate containing a high percentage of cocoa (at least 70%). Such chocolate is also filled with antioxidants. Do not overdo it though, as chocolate is very calorie-rich.
Chili
Many dishes can spiced with hot chili. Chili is rich in capsaicin, a substance proven to lower blood pressure.
Make use of the BMR calculator to calculate your basal metabolic rate and see if you are above or below required caloric intake. http://healthiack.com/bmr-calculator

Hi, jbb85! :)

People living the FTS lifestyle should NOT eat raisins, bananas, chocolate, or watermelon.
ALL those things are high in net carbs! :o

To control blood pressure, the two best means are weight loss (if overweight) and exercise.

My blood pressure was VERY high when I started FTS and was taking 3 meds for it.
After 6 months, my BP lowered to normal (for my age) and I ditched the drugs! ;D ;D ;D

One thing about blood pressure...
As we age, our bodies lose their elastic abilities. This includes our arteries.
This results in slightly higher BP readings than younger folks.
