Weight Loss Forum / Low Carb / March 2004Aspartame and Phenylalanine
In Atkins he recommends stevia rather than aspartame because of the carbs. I found a nice tasting non-sugar candy here in Tokyo with lemon and herb extracts (very pleasant) that is sweetened with aspartame, phenylalanine and stevia. No mention of sorbitol or other "tols" that seem to cause digestive complaints. I did some looking on the Internet and found some very scary pages warning about the neuro-toxic effect of Phenylalanine. But a more reputable-looking site - Harvard: http://www.joslin.harvard.edu/education/library/aspartame.shtml says aspartame and phenylalanine are safe for people without a certain genetic defect. An interesting quotes from the site: With regard to blood sugar and weight loss: "There is no question that aspartame has been beneficial to people with diabetes, enabling them to enjoy sweet tasting foods without the carbohydrates. Since it does not contain calories in the usual amounts consumed, it cannot affect blood sugar levels or cause weight gain." doug > In Atkins he recommends stevia rather than aspartame because of the carbs. > [quoted text clipped - 5 lines] > I did some looking on the Internet and found some very scary pages warning > about the neuro-toxic effect of Phenylalanine. Phenylalanine is an essential amino acid that's found in nearly every protein rich food. it's not neuro-toxic unless you consume massive quantities of it. much more than you could get from aspartame. Phenylalanine deficiancies could play a part in Parkinson's disease. there have been people trying to get rich on "aspartame detox" programs and nutrasweet lawsuits for as long as it's been out. and AFAIK, there aren't any serious studies to back up their claims. unless you have phenylketonuria, it probably won't affect you in any noticible way. some people here find that aspartame increases their food cravings, but phenylalanine on it's own has been used as an appetite supressant, so YMMV. -kelly > Phenylalanine is an essential amino acid that's found in nearly every > protein rich food. it's not neuro-toxic unless you consume massive > quantities of it. Or if you have PKU. To the original poster... aspartame (which is made from phenylalanine) does not have carbs. What Atkins and others warn about is the little blue packets which contain aspartame and fillers, the fillers being carbs. Sucralose is the same - the fillers are the problem, not the sucralose itself. > Or if you have PKU. right. and which i stated in the post you're responding to. -kelly . It would be good if everyone were able to use it. I get a raging headache after I drink more then 6 ounces of diet soda. I stopped drinking it for five years and just tried it again. The answer for me is- don't drink it. Perhaps some one knows of a brand of soda that is a no carb soda, but not sweetened with aspartame?

It's a fairly rare disease. There are a lot of foods that have phenylalanine in it so if you are a phenylketonuric you would know very early. "Phenylketonuria (PKU) is an inherited error of metabolism caused by a deficiency in the enzyme phenylalanine hydroxylase. Loss of this enzyme results in mental retardation, organ damage, unusual posture and can, in cases of maternal PKU, severely compromise pregnancy."

Therefore, there is a link between the music of Frank Sinatra and heart disease and cancer. --Tony Lew |
