Fake Sweetness >> Real Fat

In an effort to spare calories and avoid weight gain (not to mention tooth decay), many of us rely on artificial sweeteners to give us that hit of sweetness we crave, without the extra calories. There are a variety of artificial sweeteners on the market - aspartame/Nutrasweet, Equal, sucralose/Splenda, acesulfame-potassium, Saccharin/Sweet n Low, Neotame, and some of the newer sugar-alcohols like Erythritol, Sorbitol, Xylitol, Mannitol (not exactly artificial, and not calorie-free, but about 1/2 the calorie-content as sugar). We know that excess sugar leads to weight gain and tooth decay. It also contributes to the development of conditions like diabetes, heart disease, and even osteoporosis and other mineral deficiency conditions. But as bad as sugar can be in our diets (at the levels of intake typical for our society), are artificial sweeteners really the solution? More and more studies are showing that we really can't have our cake, and eat it too.

What's so bad about artificial sweeteners?
The internet is crawling with articles that outline the many negative symptoms and diseases that may be associated with intake of artificial sweeteners (check out the blog at www.drmercola.com for some really well outlined articles). Aspartame is the most controversial, and issues with Sucralose (now that it has been debunked as "natural" given that it was in fact discovered when manufacturing an insecticide, and is made of a combination of sugar and chlorines, a proven carcinogen) are appearing more and more often. These additives were approved based on short term studies, and only in recent years can we start to know the long term effects. Once again, we as a society have participated in one giant scientific experiment. What's more, we are now starting to see more and more products being created with a mix of different sweeteners, and we have no idea what the effects of this might be. Studies that indicate there are no significant negative effects are often funded by the very industries that profit from them. The range of symptoms that may be related to artificial sweeteners includes:

• headaches & migraines
  
• breathing difficulties
• skin eruptions/rashes
• cancer
• allergies
• aspartame disease
• depression
• fibromyalgia
• digestive disturbances
• liver and kidney toxicity
  

And... WEIGHT GAIN. I want to focus on this one, since the most common reason people choose to use artificial sweeteners is for weight control purposes. Given that these fake sweeteners have virtually no calories (or even if they have calories, they are so many more times sweeter than actual sugar that only small amounts need to be used to reach the desired sweetness level that the calories are negligible), how can they lead to weight gain? Aha, this is where we have a very clear demonstration that weight control is NOT all about calories in vs calories out!

How do artificial sweeteners contribute to making us fat?
Repeatedly, studies with rats are demonstrating two principal ways that artificial sweeteners contribute to weight gain*:

1. The sweet taste with the absence of calories "tricks" our body chemistry, breaking the connection between a sweet food and a high-calorie intake, and leads to a break-down in our body's ability to self-regulate caloric intake and satiety. This leads to overeating and constant cravings for more food.
2. Foods have thermogenic effects; when we eat them, our core body temperature and metabolism rise, increasing the calorie-burn capability. When we eat sugar, this occurs. When we eat artificial sweeteners, core body temperature does not rise like it does with higher calorie foods, and therefore LOWERS are metabolic burning ability.

These 2 effects combined will lead to weight gain in the long run if artificial sweeteners are used on a regular basis. In addition to the many possible health implications these additives may be related to, and you have to ask yourself if they are really worth it.

So now what?
If you've decided that you are ready to kick the fake sweetener habit, here are some strategies to help:

• Cut out diet pop first: This is usually the main source of intake of these additives. If you feel the need for the caffeine that is often in your beverage, substitute with herbal or green tea (try making some iced tea out of it if you prefer a cold drink). If you miss the fizz factor, have a glass of sparkling mineral water (aka: Perrier, etc) and squeeze in some fresh lime or lemon.
• Yogurt is another major source of intake: Replace sweetened yogurt with plain yogurt (goat's preferably), and "sweeten" naturally with fresh fruit (blueberries, raspberries, strawberries, diced peaches), and/or a teaspoon of maple syrup, agave nectar, or honey. Add in some walnut chunks and a teaspoon of ground flax for a great serving of essential fatty acids, increased satisifaction, and fill-you-up goodness!
• Eat a well balanced diet: INCLUDING healthy sources of whole grains (whole wheat, quinoa, oatmeal, kamut, millet...) and essential fats (avocado, olives and olive oil, nuts and nut butters...). Skimping on these foods that are often avoided like the plague by dieters who believe that low-carb and fat-free will help them achieve the sleek physique they desire will in fact only lead to constant cravings due to imbalance and lack of satisfaction. Enjoy them in balance with healthy sources of protein to help reduce cravings.
• Use healthy sweeteners (minimally): Maple syrup is my favourite (full of all the health supportive minerals that are stripped out of refined sugar). Agave nectar (a syrup from a cactus plant, that does not have the same impact to insulin in the body that sugar does), and raw honey (unpasteurized) are also excellent. Xylitol is also becoming easier to find in health food stores; it looks like sugar but is much sweeter, you can bake with it, and it even has antibacterial properties so helps resist dental cavities. Finally there is Stevia, an all natural sweetener that contains phytonutrients and trace minerals, and is many more times sweeter than sugar. Personally I find it has a bit of an aspartame taste to it, but it's not bad and you really only need a pinch. Please note: Agave, Xylitol, and Stevia all have possible negative impacts and have not been thoroughly researched, so use with discretion and minimally!
  
• Do expect that you're going to go through a period of craving for sweets: You've trained your body to want them, and it will take some time to readjust and retrain your taste buds too. Hang in there!

*studies were conducted with rats and response to saccharin; it stands to reason that the same effects would occur with other artificial sweeteners, however further research needs to be done to demonstrate that. As well, while these studies have not been done with human subjects, anecdotal evidence of the increase in the rate of obesity since the 1980's when these sweeteners started to become widely used in a variety of foods and beverages does support that they are certainly not helping us to control our weight.
