Another study observed that drinking diet soda was associated with greater waist circumference over 9—10 years On the other hand, many human intervention studies indicate that the use of artificial sweeteners is either neutral or beneficial for weight management. In one 6-month, randomized, controlled study, people with overweight or obesity experienced moderate weight loss of 2—2.
In another study, people in a week weight loss program who drank artificially sweetened beverages lost 13 pounds 6 kg , while those drinking water lost 9 pounds 4 kg Thus, the evidence on the effects of artificially sweetened beverages on weight management are conflicting, and more research is needed.
The evidence on the use of Coke Zero and other artificially sweetened drinks for weight management is conflicting. More research is needed to understand the benefits and risks of diet beverages. Similarly to regular soda , drinking diet sodas like Coke Zero is associated with an increased risk of tooth erosion.
One study on human teeth noted that phosphoric acid causes mild enamel and tooth erosion Still, keep in mind that citric acid has been found to erode teeth more than phosphoric acid, which suggests that Coke Zero may affect tooth enamel slightly less than Diet Coke Additionally, Diet Coke had less erosive effects than other beverages, such as Sprite, Mountain Dew, and apple juice The acidic pH level of Coke Zero is associated with an increased risk of enamel and tooth erosion, though it may affect your teeth less than other acidic beverages.
Coke Zero is sugar-free. However, the sugar substitutes it contains may not necessarily be a healthier option for people looking to reduce their risk of diabetes. A year study in 66, women observed an association between drinking artificially sweetened beverages and an increased risk of type 2 diabetes Another study in 2, people showed a link between both sugar-sweetened drinks and artificially sweetened diet beverages and type 2 diabetes, suggesting that switching to diet soda may not lower your diabetes risk If those of us that have PKU do not follow a strict low protein diet, phenylalanine is not adequately digested in our bodies and it builds up in our blood in the form of an acid called phenylpyruvic acid.
Depending on the severity of the PKU, babies who were not treated for the disorder and put on the special diet at birth run the risk of suffering irreversible mental retardation within the first year of life.
PKU is certainly a detrimental disorder if not treated properly, but the prognosis isn't nearly as grim as the preceding paragraph suggests.
If babies are put on the low protein diet at a young age, and they follow the diet throughout life, there is no evidence that their PKU will be a major hindrance in their accomplishments. In fact, in some cases, myself included people with PKU view their disorder as being a positive trait, one which has taught them to be more self-disciplined. In the past, children were taken off the low protein PKU diet at age 5 or 6 because it was believed that at this age the brain had developed to the point where elevated levels of phenylpyruvic acid in the blood would not cause severe health problems.
These children are now adults; many of them have noticed health problems and have decided, of their own accord, to return to the PKU diet. These days, most doctors that provide care for PKU patients preach that the low protein PKU diet should be a way of life and, if we value our health and well-being, those of us with the disorder should never stray from it.
One question that I often get asked by people who read this webpage - "Is phenylalanine harmful to people that don't have PKU? If phenylalanine is in it's natural form, then the answer to this question is a great big resounding NO.
Phenylalanine is an essential amino acid that is in nearly all proteins - meats, dairy products, eggs, nuts, legumes Some researchers claim that the amino acid phenylalanine is a natural muscle relaxer and sleep aid.
