Blueberry is a berry that is rich in vitamins and fiber. Many people believe that in addition to consuming blueberry has various health benefits, it may have medicinal properties for the elderly. Such as lowering blood pressure, reduce the risk of ischemic heart disease, or may contribute to a brain supplement, etc.
Blueberry is one of the most popular fruits used in food, desserts, and beverages, and 100 grams of fresh blueberry contains 84 percent water and only 57 calories. It is also rich in potassium, phosphorus, fiber, vitamin K, and many other beneficial nutrients such as flavonoid, some studies have shown that this substance may have heart and brain health benefits for the elderly as well.
However, at present, some scientific evidence proves the various benefits of Blueberry:
- Lower blood pressure
High blood pressure may be treated with basic dietary modifications. By focusing on eating fruits and vegetables that are high in fiber. Some studies have shown that fruit like blueberry may help lower blood pressure in humans.
In one study, the effectiveness of blueberry lowering blood pressure levels in postmenopausal women prehypertension and hypertension stage 1 found that taking blueberry powder or blueberry infusion hardened for 8 weeks may help lower blood pressure levels and reduce hardening of the arteries. By increasing the production of Nitric Oxide in the body, which helps to widen the blood vessels until the blood flows better.
As well as another study examining the same efficacy in 25 postmenopausal women and men, blueberry may help lower blood pressure levels when consumed for six consecutive weeks.
Despite the effectiveness of several experiments, But the above research is only a study in a small group. Therefore, it cannot be confirmed that consuming blueberry can help lower blood pressure. Therefore, it should be studied in a wider variety of experimental groups and the number of experiments. In order to be able to apply the results to the actual treatment of hypertensive patients.
- Reduce the risk of ischemic heart disease.
Myocarditis can occur for a number of reasons. As well as from various risk factors around you such as smoking, stress, or diet. Which is one study that studies in mice and found that consuming foods rich in blueberry may reduce the risk of myocarditis.
Another study that followed the diet of 93,600 middle-aged women every four years for a period of 18 years found that the subjects who consumed fruits and vegetables containing anthocyanins, such as blueberry on a regular basis, maybe at a lower risk of ischemic heart disease than other subjects.
However, some studies are conducted in laboratory animals only. Therefore, the efficacy of consuming blueberry could not be confirmed to reduce the risk of myocarditis in humans. Therefore, more human studies should be conducted on the efficacy and safety of consuming this fruit. To produce beneficial results in further medical practice.
- Brain Nourishment
As begin to enter old age, the performance of the system in the body may begin to deteriorate with age, especially brain function, as there may be signs of Alzheimer’s dementia as they begin to age. Health and brain care can be achieved by exercising or eating a healthy diet, with some research finding that blueberry intake may help nourish the brains of the elderly.
One study conducted a questionnaire to explore the deterioration in brain function after eating flavonoids and berry fruits. The study involved 16,010 women aged 70 and over for four years. Found that eating large amounts of flavonoids Especially from the fruit family of berries like strawberries and blueberries. May contribute to reducing the rate of deterioration in the brain’s functioning system in the elderly.
Another research, a 12-week trial of older adults with early memory problems to drink blueberry juice was found that drinking blueberry juice may improve memory function in the elderly with memory problems. In the early stages.
However, some research remains very limited. Because many experimental factors cannot be controlled. Therefore, it is important to further study the benefits of Blueberry for the brain. In order to bring clear results to develop products or brain supplements for the elderly in the future.
