Aside from being a tasty little addition to banana bread and oatmeal cookies, raisins could also have benefits for blood pressure, according to a small new study.
Researchers from the Louisville Metabolic and Atherosclerosis Research Center found that snacking on raisins three times a day could mildly lower blood pressure, compared to other kinds of snacks -- a promising finding for people who may not have full-blown hypertension, but are on the cusp of high blood pressure.
"Our study suggests if you have a choice between eating raisins or other snacks like crackers and chocolate chip cookies, you may be better off snacking on raisins at least with respect to blood pressure," Dr. Harold Bays, M.D., medical director and president of Louisville Metabolic and Atherosclerosis Research Center, said in a statement. His research was presented at the American College of Cardiology's 61st Annual Scientific Session.
The study included 46 men and women with prehypertension. Prehypertension is defined as having a systolic blood pressure level between 120 and 139 millimeters of mercury, or a diastolic blood pressure level between 80 and 89 millimeters of mercury. A normal blood pressure level is defined as having a systolic blood pressure level of 120 or less, and a diastolic blood pressure level of 80 or less; hypertension is defined as having a systolic blood pressure level of 140 to 159 or a diastolic blood pressure level of 90 to 99.
The researchers had the study participants either eat raisins or some sort of prepackaged commercial snack, like crackers or cookies (that didn't contain any raisins, vegetables or fruits) that had the same amount of calories. All the study participants ate the snacks three times a day, for 12 weeks.
The researchers found that the raisin-eaters had reduced systolic blood pressure (the top number in a blood pressure reading, meaning "as the heart beats," according to the National Institutes of Health) and diastolic blood pressure (the bottom number in the reading, meaning the relaxation of the heart between heartbeats). However, the pre-packaged snack-eaters didn't see any significant drops in their blood pressure.
Researchers said they are not yet sure how raisins could have an effect in lowering blood pressure -- and that bigger studies are need to confirm the link -- but raisins' nutrition values include being high in potassium (which could lower blood pressure) and containing antioxidants, fiber, polyphenols and phenolic acid.
And raisins aren't the only food linked with blood pressure benefits. Click through the slideshow for seven other foods that could help your BP, naturally:
That study included 188 men and women age 55 and older, with slightly high blood pressure. They were instructed to eat three kiwis a day, or an apple a day for eight weeks.
The researchers found that the people who ate the kiwis had lower systolic blood pressure levels than those who ate the apples.
Kiwis are known to be rich in lutein, which means they have antioxidant properties.

Being vegan in society as it exists today can be difficult. The number of popular vegan products available are still relatively few (though that number is growing), and the ones that do exist are mostly restricted to the affluent countries of the world. Most pharmaceutical products and many cosmetic products are tested on animals. In addition to that, food at major institutions, like prisons and hospitals, do not cater to vegans. This presents a major problem for people who choose to follow a vegan lifestyle. In order for veganism to truly move into the mainstream, it is imperative that vegan rights are recognized not just by society, but also by our governments.
Some people see veganism as a luxury, but others are ready and willing to fight for the access to a vegan lifestyle as a right. It’s important for those who feel this way to stand up for vegan rights, and to ensure that the current system evolves into a sane and sustainable way of living that will allow people from all walks of life to make the vegan transition easily and comfortably.
Vegan rights involve:
In order to survive in this speciesist world, we need formal recognition of vegan rights. It’s difficult to live in a society where one’s values and our ideology are not understood, much less accepted. The recognition of vegan rights would also allow us, as a movement, to reach out to more people – of all backgrounds and walks of life – and to ensure that everyone who wants it has an equal opportunity to embrace veganism as a lifestyle.
How can vegan rights be established?
One of the ideas proposed by longtime animal rights activist, David Sztybel, is that vegans should be acknowledged as observing a creed or religion for legal purposes. To a court of law, religious rights are attended to with conscientious devotion. Sztybel argues that if veganism were recognized as a creed, governments would have to take vegan interests seriously and establish the above-mentioned rights. Like boys of the Sikh faith who are allowed to carry kirpans or ceremonial knives to school, the right to veganism, and all the lifestyle implications that come with it, would come under religious freedom. Vegan products, for example, would have to be labeled as such - like kosher and halal meat are labeled by law.
But is proposing veganism as a religion the best way to achieve rights for vegans? Religion does have negative connotations for some people – do we want to align veganism with that? As a movement, our aim is to inspire and invite non-vegans into veganism. If the movement was officially recognized as a religion, would it separate vegans even more from everyone else? Even worse, would some current vegans move away from identifying with the movement as a result? Vegans could be looked at as a cult, believers of faith with irrational ideals. Veganism isn’t a blind faith. It is a product of moral evolution. We don’t need scriptures to tell us to be compassionate. Would the benefits of establishing vegan rights through the framework of religion outweigh the risks of taking such a step?
While I believe that the establishment of vegan rights is an important step in bringing veganism into the mainstream, I’m not convinced that labeling veganism as a religion is the best way to do that. What are our other options? Share your thoughts and ideas here…
