A recent study suggests that a poor-quality diet may increase the chances of weakness in older people. Researchers found that people with poor-quality diets were almost two times as likely to become frail compared to those with high-quality diets. They believed that protein intake might also be important to reduce frailty risk. But that is not what the study found. There was no meaningful difference in frailty risk based on total protein intake, animal protein intake or total calories in a person’s diet. Despite the limitations of the study, one thing is for sure. That is, following dietary suggestions may help older adults lower their risk of severe frailty. And U.S. dietary guidelines urge people to eat whole fruits, fresh vegetables, whole grains, low-fat milk and dairy products and protein from many sources. The guidelines also advise against eating foods that contain a lot of salt, saturated fat and sugar. (152 words)

People around the world are bitterly divided about which animal is the better pet, a dog or a cat. But a new study may have found a clear winner when it comes to which animal is more intelligent: the dog. Researchers found that dogs have many more neurons in the cerebral cortex than cats do. To be specific, dogs have about 530 million cortical neurons while cats have about 250 million. That area of the brain, or the cerebral cortex, is connected to thinking, planning and complex behavior. These are considered key to understanding an animal’s intelligence. According to the study, the higher the number of neurons an animal has, the greater their ability to predict what is about to happen in their environment based on past experience. The study’s findings mean that dogs may be able to do more complex things in their lives than cats can. (152 words)

There have been many studies on the health benefits of coffee, say, coffee drinkers had a lower risk of heart and liver disease and some cancers, and they also had a lower risk of dying from stroke. However, researchers could not prove coffee was the cause of these lowered risks. Besides, they found too much coffee during pregnancy can be dangerous; people, especially women, whose bones break easily should limit how much coffee they drink; and that people with abnormal heartbeat patterns are advised to drink decaffeinated coffee. Researchers said that to get the full health benefits of coffee, keep it simple. Drinking it black is the healthiest. And skip the pastries. So the final takeaway is, if you drink coffee, keep it simple and don’t eat the pastries or other baked treats that often come with a cup of coffee. And if you’re not a coffee drinker, you don’t need to start drinking coffee to be healthier. (164 words)
