    Avoiding Artificial Sweeteners 

    Not only are most artificial sweeteners bad for you but some studies have shown that they may actually make you crave more food. They trigger a response in the body that makes the sensation of hunger return sooner. If a label says “lite,” “sugar-free,” or “low-calorie” the product most likely has an artificial sweetener. Also, products that have warnings for phenylkinetics contain aspartame. Artificial sweeteners often have a bad or “off” aftertaste and leave a slimy feeling in your mouth. They are also known the cause headaches ranging from mild to severe migraines.

    Artificial sweeteners currently approved by the FDA are acesulfame-K, aspartame, saccharin, sucralose, neotame. Artificial sweeteners banned by the FDA are cyclamate (however it has been submitted for reapproval), dulcin, glucin, and P-4000. Alitame has been submitted by Pfizer for FDA approval.

    Acesulfame-K is also called acesulfame potassium, Sunette, Sweet One and Sweet ‘n Safe. It is about 150-200 times sweeter than sucrose. It is normally used in conjunction with aspartame or other sweeteners to give it more of a “sugar like” taste. It is heat stable and can be used in baked goods. It is currently in approximately 4000 foods including chewing gum, desserts, alcoholic beverages, syrups, candies, sauces and yogurt. Acesulfame-K has a bitter aftertaste and Kraft Foods has patented the use of sodium ferulate to mask the taste.

    The safety of acesulfame-K has not been proven and some studies have shown that it can cause cancer. The National Toxicology Program has claimed that it is safe in doses less than 3% and has recommended further research into its safety.

    Aspartame is also known as Equal, Nutrasweet, and Canderel. It is about 160-220 times sweeter than sucrose and contains 4 calories/gram. Since it is so sweet only a small amount is needed for sweetening so it is labeled as zero calorie per serving. Aspartame is in diet sodas, Dannon Yogurt, Swiss Miss Cocoa Mix and numerous candy. Overall it is found in approximately 6000 foods worldwide and is often seen as a table condiment. Aspartame does not taste like sugar and is often mixed with Acesulfame-K to give it more of a sweet taste.

    Saccharin is also known as Sweet ‘N Low and Sugar Twin. It is estimated to somewhere between 200-700 times sweeter than sugar. In 1977 a study found that it caused bladder cancer and all products with saccharin were required to be labeled with “Use of this product may be hazardous to your health. This product contains saccharin which has been determined to cause cancer in laboratory animals.” In May 2000 the US government released an updated list of things known to cause cancer and removed saccharin from the list. Saccharin is not only used as a condiment, but is in Listerine, Crest toothpaste, cough syrup, and many food items. Saccharin has a bitter or metallic aftertaste. In countries where both saccharin and cyclamate are legal they are often mixed in a ratio of 10:1 to mask the other’s off-taste. Aspartame has a relatively short shelf life so saccharin is often included in diet sodas syrup to extend the shelf life.

    Sucralose is also known as Splenda and is about 600 times sweeter than sugar. It is the only sugar substitute made from sugar and is heat stable so it can used cooking. It is in about 4500 foods worldwide and is often seen in combination with aspartame and high fructose corn syrup.

    Neotame is produced by Nutrasweet and is similar to aspartame in taste. It is between 7000-13000 times sweeter than sugar. It was approved for use by the FDA in 2002 and is one of only two artificial sweeteners that is considered “safe” by the consumer advocacy group Center for Science in the Public Interest. The other sweetener is sucralose.

    Cyclamate was banned in the US in 1969 because it was shown to cause bladder tumors in rats. It is 30-60 times sweeter than sugar and heat stable. It has an unpleasant aftertaste, although not as bad as aspartame and is often used in conjunction with saccharin to mask the taste. The FDA is currently reconsidering the ban.

    Alitame is expected to be approved for use by the FDA soon. It is about 2000 times sweeter than sugar and is expected to be used in baked goods and soft drinks.

      I read that the Miracle Berries (synsepalum dulcificum) is an interesting berry for taste loss. The berry changes sour foods to sweet, that way remove the need for sugar alternatives. I grow plants blog: Miracle Berries its my blog on this Magicalfruit.. I heard info about a doctor Mike Cusner he had 50 percent succes at clinical trials.

    What’s the Deal With Sugar? 

    Lately I have been stumbling across a lot of news stories about sugar in sports drinks, comparing them to soda, and calling them junkfood. People making these comparisons don’t seem to realize that sports drinks serve a specific purpose. They are designed to enhance exercise performance and increase endurance. Research has clearly shown that hydration and performance are improved from drinking carbohydrate (sugar) containing drinks versus plain water during exercise.

    Many people take an all or nothing approach to eating. In moderation most foods/drinks are fine, however drinking soda (or sports drinks) with very little exercise is obviously unhealthy. Same with saturated fats- most people think saturated fat is unhealthy. It’s not unhealthy in small amounts, but causes a myriad of health problems in large amounts. High fructose corn syrup (glucose+fructose) is also considered “bad.” It’s not that high fructose corn syrup is inherently unhealthy it’s that the average person consumes 60 pounds of it a year!

    Maltodextrin, sucrose and fructose are the main ingredients in most sports drinks. There is a lot of confusion regarding the types and amounts of sugars used in sports drinks and whether or not they are healthy.

    Anti-sugar campaigns claim many things but mainly that certain sugars cause an energy spike followed by a crash therefore affecting performance negatively. According to this some people claim that slow acting sugars and non sugar carbohydrates are better. The human body is not capable of absorbing carbohydrates as quickly as carbohydrates are oxidized in the muscle during moderate exercise. So to get the maximum benefit from consuming carbs during exercise it is best to consume the most rapidly absorbed and metabolized carbs. There is not an advantage to consuming carbs that take a long time to get to the muscles.

    Some complex carbohydrates such as maltodextrin perform just as well as simple sugars such as fructose, glucose and sucrose. Maltodextrin is metabolized just as quickly as simple sugars and is great for sports drinks because it isn’t sweet, allows rapid stomach emptying, and is absorbed quickly. Fructose is normally included in sports drinks because it is metabolized in a slightly different way than other sugars. When carbohydrates are consumed in amounts large enough to saturate the body’s capacity, it will still be able to metabolize a small amount of fructose. However fructose should not be consumed in large amounts because it will upset the stomach.

    Any food that is not eaten in moderation can be considered “junk food.” Sports drinks are not junk food when they are used for what they are intended, to hydrate and to improve performance during exercise.

    Healthy Alternatives: Black Beans 

    Black beans are high in fiber and magnesium, very low in fat, and very versatile. Research published in the Journal of Agriculture and Food Chemistry showed that black beans are as rich in antioxidants as grapes and cranberries. According to the research the darker the bean, the higher the antioxidant level. Black beans are also high in protein and are a good alternative to meat and dairy products that are high in calories and saturated fat. One cup of black beans provides about 15 grams of protein.

    Black beans can be purchased either dried or canned. Dried black beans need to be soaked overnight and then simmered at a ratio of 3:1 (three cups of water to one cup of black beans) for 1 1/2 -2 hours. They can also be cooked in a pressure cooker significantly shortening the cooking time. After cooking they will last in the fridge for about three days. When buying canned black beans read the ingredients to make sure they don’t have high fructose corn syrup or any other unnecessary additives.

    Black beans can be added to almost any latin or southern dish, salads, soups and chilis. Saute black beans with garlic, onions, cumin and serve over rice or couscous. Add to dips such as salsa, guacamole or bean dip. Add to quesadilla, burritos and enchiladas.

    Why is Sodium Important? 

    Sodium is important in sports drinks because it:

    1. Rounds out the flavor.
    2. Stimulates the drive to drink leading to better hydration.
    3. Is necessary for the body to function properly.

    There is not a consensus on the amount of sodium that should be included in sports drinks. It depends on differences in physical activity, environment, and variability among individuals. Generally sodium should optimize flavor- it should be subtle and not inhibit drinking.

    Adequate sodium intake is necessary for muscle function and even a slight depletion can cause problems. People who exercise in hot or humid environments and/or participate in high intensity exercise are at a higher risk of developing hyponatremia (low concentration of sodium in the blood). During high intensity exercise or exercise in hot environments sodium is lost in sweat. If fluid is only replaced with water it will dilute the blood causing sodium levels in the blood to drop. Symptoms of this are nausea, muscle cramps, disorientation, slurred speech, confusion, etc. Extreme cases can cause seizures, coma or death.

    The best ways to prevent hyponatremia are to ensure adequate sodium intake by:

    1. Using sports drinks containing sodium during high intensity exercise, or exercise in hot environments.
    2. Eating salty foods before and/or during exercise.
    3. Understanding your own fluid needs. Weigh yourself before and after exercise (the weight lost during exercise is almost all fluid) to figure out how much fluid needs to be replaced for adequate hydration.
    4. Avoiding the use of aspirin, ibuprofen and other anti-inflammatory drugs because they increase the risk of hyponatremia.
    5. During the days before exercise increasing sodium intake.

    Out of the electrolytes included in sports drinks sodium is the only one that research has shown to play any significant role in rehydration.

    Electrolytes 

    It’s essential to replace electrolytes after exercise lasting longer than an hour, exercise in the heat, or any strenuous exercise. Many people don’t know what electrolytes are or how they affect the body.

    The main types of electrolytes are sodium, potassium, calcium, magnesium, chloride, and phosphate. In order for the body to function it must have the proper balance of electrolytes. The purpose of electrolytes is to transport fluid from one cell to another keeping the body hydrated, regulating blood pH, and allowing the muscles and nerves to function properly.

    Most electrolytes are replaced in adequate amounts by eating a balanced diet. If the body gets to many electrolytes they are flushed out, if it gets to few it can’t function properly impairing performance. The main electrolytes that need to be replaced during exercise are sodium and potassium. For exercise lasting a short time water is fine, but for anything longer or in a hot environment a sports drink or electrolyte replacement drink should be used. Water and electrolytes need to not only be replaced during training but afterwards as well. Also, if you have been sick or are dehydrated, electrolytes should be replaced along with water.
