Probiotics may help lower blood pressure
In addition to helping your gut, probiotics may also help lower your blood pressure. According to new research from Griffith University in Australia, consuming probiotics–a form of healthy bacteria–from either food sources, such as yogurt, or dietary supplements, can have a positive impact on blood pressure.
The research team analyzed nine high-quality studies of probiotic effects in 543 individuals with either normal or high blood pressure. They found that people who took daily probiotics for eight weeks or longer had a 3.5 mm Hg lower systolic blood pressure and a 2.38 mm Hg lower diastolic blood pressure compared to people who were not on probiotics. The best results were found in people with high blood pressure of 130/85 mm Hg or greater.
Probiotics not only lowered high blood pressure, it maintained healthy blood pressure as well. Probiotics containing multiple bacteria were the most effective. However, taking probiotics for less than eight weeks did not change blood pressure.
It’s believed that probiotics affects blood pressure by lowering blood sugar and cholesterol levels, limiting insulin resistance and regulating hormones that control fluid balance and blood pressure.
The researchers noted that probiotics should not be recommended for high blood pressure treatment until further studies are performed.

Can bad diet cause loss of smell?
There already are plenty of reasons to reduce fatty foods in your diet—and the list is getting longer. Research at Florida State University has found that eating high-fat foods can affect the olfactory system and impair the sense of smell permanently. The study, published in Journal of Neuroscience, is the first to show a direct correlation between bad diet and smelling loss.
For six months, the researchers fed mice a high-fat diet and trained them to distinguish between a certain odor and a reward–in this case the reward was water. Mice on the high-fat diet had difficulty learning the odor-reward connection compared to a control population. When a new odor was introduced, the mice on high-fat diets were slow to adjust, which researchers said reflected more limited smelling abilities.
The scientists then discovered that when the mice returned to a healthy diet and lost weight, their olfactory senses were still impaired. In fact, the high-fat diets affected the olfactory senses so much that, according to the researchers, only 50 percent of their neurons could encode odor signals.
The study, funded by the National Institutes of Health (NIH), shows how obesity can affect the body in ways not usually associated with it.
