Can Coffee Be Good For The Health? Drinking a cup of hot coffee in the morning is probably most people will do to start their day. Coffee is a drink made from coffee beans. It contains caffeine that works by stimulating the central nervous system, heart, and muscles. People drink coffee to relieve mental and physical fatigue and increase mental alertness. But caffeine in the coffee may cause insomnia, nervousness and restlessness, stomach upset, nausea and vomiting, increased heart and breathing rate, and other side effects in some people. While its health benefits are controversial, growing research has pointed out that moderate consumption of coffee might offer some protection against heart disease, Type-2 diabetes, liver disease, Parkinson’s disease, and stroke. It is also linked to lower risk of Alzheimer’s disease. This might be due to the fact that coffee beans contain some essential nutrients and is extremely high in antioxidants. It is an amazingly potent collection of biologically active compounds. In 2012, large study that followed 40,000 men and women aged between 50 and 71 for 13 years reported that those who regularly drank coffee, either decaf or regular, had a lower risk of overall death than did nondrinkers. In particular, the coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections. The study, which was conducted by NIH's National Cancer Institute and AARP (American Association of Retired Persons), was published in the ‘New England Journal of Medicine’. Both regular and decaf were associated with a lower risk of dying, suggesting that other substances in coffee might be more important than caffeine. But even decaf contains trace amounts of caffeine, so it is difficult for the researchers to entirely rule out the possibility that caffeine has an effect on health.
Recent research has link consumption of coffee to weight loss. In a paper published in 2019 in revealed that one cup of plain coffee could stimulate brown fat. Brown fat, also called baby fat, generates heat and burns calories, as opposed to other types of fat which might contribute to inflammation, insulin resistance, and further weight gain. 9 healthy male and female volunteers were tested in the study conducted by scientists from the University of Nottingham to see whether caffeine stimulates brown fat. The participants were scanned before and after they drank either a cup of coffee (with about 65 mg of caffeine), or plain water using thermal imaging. The results indicated that drinking a single, standard cup of coffee may stimulate brown fat that would raise the body’s metabolic rate, in other words, coffee helps make these brown fat cells work hard to burn more calories. Nevertheless, the study did not show that participants lost weight from drinking coffee, and brown fat has not been proven to play a role in overall body metabolism considering human has so little brown fat. Meanwhile, the study did have limitations, for instance, the researchers only used a small sample size of participants who all have normal weight. Their next step is to determine how to get the body to make more brown fat and boost metabolism. Healthy adults who consume about 4 to 5 cups of coffee (945 ml) or 400 mg a day should not have any dangerous, negative effects, according to the Food and Drug Administration (FDA). This, however, again depends on how sensitive people are to the effect of caffeine and how fast they metabolize it. For some individuals, excessive consumption of coffee may cause negative side effects, like anxiety, panic, restless sleep, insomnia, and caffeine dependence. Meanwhile, this may also lead to potential health issues including reduced calcium and iron absorption; increased heart rate; worsening irritable bowel syndrome (IBS); gastroesophageal reflux disease (GERD); increased blood glucose levels; Fertility issues. It can also temporarily raise blood pressure. Women who are pregnant, trying to become pregnant or breastfeeding need to be cautious about caffeine. High intake of boiled, unfiltered coffee is linked to mild increase in cholesterol levels. Caffeine interacts with some medications, too. Date: October 15, 2020
