The research by Imperial College London suggests that there is no solid proof that low-calorie sweeteners or diet drinks are better as compared to full-sugar drinks. The study in the American Journal of Public Health of the U.S. adults showed that 11% of U.S. adults who were at healthy weight, 19% with overweight and 22% obese consumed diet beverages. Meanwhile, the study on 3,700 people for eight years showed that consumption of low-calorie sweeteners put on maximum weight.
The sweetness in low-calorie drinks can confuse the brain
Low-calorie drinks being as sweet as normal drink can confuse the human body. Yale University researchers have found that sweetness in nature shows the presence of energy. Hence, something that tastes sweet contains more calories. And when the drink is too sweet for calories, brain does not register that calories have been consumed, and this can lead to overeating. Moreover, a lower-calorie, sweet tasting drink has a tendency to trigger more metabolic response as compared to normal drinks with higher calories.
According to the study, adults consuming one diet drink per day is three times at the risk of dementia and stroke. Hence, according to the researchers, these diet drinks should stop being considered as healthy alternative. A study including 4,400 adults showed diet drinks are likely to cause strokes as compared to full sugar drink. While according to the researchers at Boston University artificial sweeteners like saccharine and aspartame can affect blood vessel and cause strokes.
Some researchers have also found that people who consume sugary drinks such as soda have smaller hippocampi and small brain volume. While people consuming sugar drinks are at the risk of developing memory problems.
Most of the countries have started introducing soda tax, which will reduce the sales significantly. Hence many major players are trying to prevent such measures. Researchers have also found that many soda companies are entering into financial ties with public health community in order to fight against these regulations. Moreover, it has also been found that many public health organizations remained silent and were turning against soda tax after joining hands with soda companies.
However, various research also suggests consumption of diet drinks can also reduce good bacteria by 50%, can increase pH level in intestine. Moreover, diet soda can actually double the risk of obesity and promote weight gain, posing critical health risks.
