Artificially sweetened drinks are often promoted as healthy alternatives for weight-loss and diabetic issues because they are low in calories and don't contain glucose. However, there is plenty of evidence to suggest that these eating plan soft drinks are harmful to human health.
According to Sharon Fowler, MPH, an authority on this subject, "Diet carbonated drinks is not a health meals. In fact, it's not a meals at all, it's simply a slurry of chemicals, a number of which may have deleterious effects on the body." Most recently diet soft drinks have been tied to increased risk of stroke and heart attack, and while many people drink them as an aid to fat loss, studies suggest if you drink diet carbonated drinks, excess bodyweight may be the result instead.
Weight gain
In one study linking diet drinks to weight gain, Hazuda, et. al. at the University of Texas Health Science Center in San Antonio, recorded changes
in waist circumferences in 474 elderly members in a 10-year study. As part
of the analysis they controlled for diabetic issues, physical activity, neighborhood, age, sex and ethnicity.
Findings showed that increases in hips sizes were 70 % greater among those who consumed diet soft drinks compared with those who did not. In addition, waist size increases were as much as 500 % greater amongst those that consumed two or more diet soft drinks a day.
In other analysis, Sharon Fowler and colleagues studied eight years of data based on individuals between 25 and 64. Of the analysis participants who were of normal weight in the beginning, a third were overweight or obese eight years later. In evaluating the correlation between being overweight and diet drinks scientists found that every bottle of diet soda participants consumed in a day raised their being overweight risk by 41 %.
Diabetes
Aspartame, a common sweetener in diet drinks, has also been linked to diabetic issues. In an animal study conducted at UT San Antonio, scientists fed corn oil-enriched feed to one group of mice and the same feed plus aspartame to another group. Three months later the aspartame team had elevated blood sugar levels but levels of insulin that were equal to or less than those of the controlled group, suggesting that aspartame may be part of the connection between diet soda consumption and diabetic issues.
Corrupted Signals
What is the reason for the diet carbonated drinks excess bodyweight connection? One theory is that our bodies rely on a signaling system based on the quality of the meals we eat. In the case of diet carbonated drinks, one's human body experiences a sweet flavor and expects calories; but when they aren't forthcoming starts to crave meals, which leads to overeating.
Psychologists at Purdue University tested this idea by comparing two groups of mice, one which was fed natural with glucose and one which was fed natural with saccharine. The saccharine mice ate significantly more calories, gained more bodyweight and put on more human extra fat than the control team.
Sweet Cravings
Still another possibility is that eating sweets dulls our preferences causing us to eat more sugary meals in compensation. Some 2011 analysis in the UK seems to support this idea. The scientists found that consumption of two cans of carbonated drinks a day for a month resulted in a noticeable dulling of preferences and increased urges for high calorie meals. Since sugar substitutes (which were not part of this particular study) are 200 to 300 times sweeter than sugar, it is at least possible that they may have a similar impact on our taste preferences.
