Known as a silent killer, high blood pressure is a much more common issue than we believe. It is a condition where the blood pushes against your artery walls, creating pressure. It not only increases the chances of heart disease and strokes but was a contributing cause of 664,470 deaths in the US, according to the Centers of Disease Control and Prevention. So how does one tackle this issue? New research suggests that drinking a bit of vegetable juice every day might help older folks lower their blood pressure. Beetroot juice is especially good because it has a lot of something called nitrate. Nitrate is important for how our bodies work and has been linked to lower blood pressure and healthier blood vessels. How Beetroot Juice Might Work: A Mouth-Body Connection Researchers at the University of Exeter believe that beetroot juice's positive effects on heart health could be due to changes it makes to the bacteria in your mouth. In their study, participants drank either regular beetroot juice (full of nitrate) or a placebo drink (with nitrate removed). When people drank nitrate-rich beetroot juice, tests showed a decrease in certain mouth bacteria called Prevotella and an increase in beneficial bacteria like Neisseria. Notably, older participants in the study started with higher blood pressure on average. Their blood pressure went down after drinking the nitrate-rich beetroot juice, but not when they drank the placebo. Science Behind Why It Helps One of the researchers explained that this study shows how foods rich in nitrate can change the tiny organisms in our mouths. These changes could then lead to less swelling (inflammation) in the body and help to lower blood pressure in older people. This discovery is exciting because it opens the door for bigger studies to look more closely at how things like what we eat, and even if someone is male or female, affect how their body reacts to getting more nitrate from their diet. It helps us understand the hidden ways food can impact our health. What the Study Found The study involved two groups of adults: one group of 39 younger people (under 30 years old) and another group of 36 older people (in their 60s and 70s). Each person in the study tried both the real beetroot juice and the fake juice for two weeks at a time. The researchers observed that the changes in mouth bacteria happened in both the younger and older groups. However, the drop in blood pressure was only seen in the older participants. Another researcher from the study mentioned that we already know that eating foods rich in nitrate is good for our health. She also pointed out that as people get older, their bodies naturally produce less of something called nitric oxide, which is important for blood vessels. Older adults also tend to have higher blood pressure, and high blood pressure can lead to serious heart problems like heart attacks and strokes. So, encouraging older adults to eat more vegetables with nitrate could offer really significant and lasting health benefits.
