How Sweet It Is: A Look at Sugars and Sweeteners |
|
The use of sugar, sweeteners, and sugar substitutes has often been a topic of hot debate. Until recently, using sugar has been discouraged in diabetic meal planning. Current scientific studies have not supported the necessity of completely abstaining from sugar, and now it’s becoming widely accepted that sugar may be used in moderation without causing deterioration in blood sugar control. Countless studies have investigated the safety profiles of artificial sweeteners.
Sugar AlcoholMannitol, maltitol, lactitol, xylitol, sorbitol, hydrogenated starch hydrolysate, and isomalt are all sugar alcohols. Sugar alcohols don’t contain sugar or alcohol, but they are a type of carbohydrate. Sugar alcohols don’t impact the blood sugar as much as regular sugars, but they do still eventually produce some glucose in the blood. Since sugar alcohols aren’t technically a form of sugar, products sweetened with sugar alcohols can boast that they are “sugar-free.” That doesn’t necessarily mean the product is “carbohydrate-free” or “low calorie.” Most chocolates that are sweetened with sugar alcohols have just as much fat, calories, and total carbohydrate as regular chocolate candies. However, sugar alcohols don’t promote tooth decay.Sugar alcohols may have a laxative effect, causing gas, bloating, and diarrhea. Tolerance varies from one individual to the next but is usually related to the amount of sugar alcohol consumed. Artificial SweetenersThe FDA has approved the following artificial sweeteners for use in the United States. The acceptable daily intake (ADIs) has a built-in 100-fold safety factor. The amounts that people actually consume are well below what has been determined to be safe.Aspartame is sold under the brand names Equal, NutraSweet, SweetMate, and NatraTaste. The FDA approved aspartame in 1981. It is 180 times sweeter than sugar. If heated at extreme temperatures, aspartame loses its sweetness; therefore, it is not acceptable for use in most cooked or baked goods. Aspartame is made of two amino acids: phenylalanine and aspartic acid. Amino acids are the natural building blocks of proteins. When aspartame is digested into its amino acid components, the body cannot distinguish whether those amino acids came from aspartame or from dietary proteins like chicken, milk, or eggs. Small amounts of methanol are produced as a by-product from digesting aspartame. Methanol is a by-product that is also produced from digesting the regular foods that we eat. Natural juices, including fruit juice and tomato juice, produce three to six times more methanol than an equal portion of aspartame-sweetened soft drink. There has been a lot of finger pointing in the direction of aspartame, but claims that it is harmful haven’t been substantiated. Whether to use aspartame or not is a matter of personal choice. Patients with a very rare metabolic disease called PKU (phenylketonuria) should not use aspartame because they need to limit all sources of phenylalanine. Acesulfame K is sold under the brand names Sunett, Swiss Sweet, and Sweet One. Gaining FDA approval in 1988, acesulfame K is 200 times sweeter than sugar. It is heat stable and can be used in baking. Sucralose is sold under the brand name Splenda. The FDA approved Sucralose in 1998. It’s actually made out of sugar but has been modified so that it doesn’t affect the blood sugar or provide any calories. It’s 600 times sweeter than sugar. It’s stable at high temperatures and can be used in baked goods. Like the other artificial sweeteners, sucralose doesn’t promote tooth decay. Saccharin is sold under the brand name Sweet ’N Low. Saccharin has been around since 1879. It’s approximately 300 times sweeter than sugar. It’s stable when heated, so can be used in baking. In the 1970s its safety came under question, as some studies showed that rats that were fed large amounts of saccharin developed bladder tumors. Saccharin has been scrutinized and studied over the past several decades and has now been determined to pose no cancer risks to humans. In May 2000, saccharin was removed from the government’s list of carcinogens (cancer-causing substances). The label warning that appears on saccharin will likely soon be dropped. |
