Too often, when we want to improve our health, it requires sacrifices like denying ourselves of good food or working out like racehorses.
But a research study based in Florida State University shows that lowering blood pressure can be refreshingly simple – all you have to do is eat a delicious summer fruit.
Arturo Figueroa, an associate professor in Florida State University made an interesting find while he was investigating high blood pressure. The study started with a concept that deaths due to heart attacks are more common in the winter than in the summer months.
The team believed that the physical stress caused by winter resulted in a rise in the blood pressure. This rise in turn makes it more difficult for the heart to pump blood and puts it in stress.
The research group identified that obese people with high blood pressure were, in particular, at a higher risk of developing heart problems. For the study, they chose 13 obese middle-aged men and women suffering from high blood pressure.
The participants were separated into two groups. One group was asked to take 4 grams of two amino acids, L-citrulline and L-arginine. The other group was given a placebo. After 6 weeks, the group that was taking placebo was given the amino acid supplements and the other group took the placebo instead.
What does this have to do with summer treat? I’ll get to that in a second, but first…
The participants were subjected to an artificial physical stress to mimic winter, by placing their hands in 39 degrees Fahrenheit (3 degrees Celsius) water. The blood pressure and other vital signs were measured. During the entire period, the participants did not take any
medications for lowering blood pressure. Nor did they do any exercises or modify their diet.
After examining the participants for a period of 12 weeks, the team concluded that the amino acids were very effective in lowering blood pressure. The amino acids stimulated the formation of nitric oxide. Nitric oxide is very effective in lowering blood pressure by dilating blood vessels.
If you’re wondering what this study had to do with the refreshing treat mentioned earlier, watermelon is a very good source of the amino acid L-citrulline. It is a natural way of lowering your blood pressure without any side effects.
