Artificial Sweeteners Associated With Weight Gain, Heart Problems In Analysis of Data From 37 Studies ( 374

An anonymous reader quotes a report from NPR: The theory behind artificial sweeteners is simple: If you use them instead of sugar, you get the joy of sweet-tasting beverages and foods without the downer of extra calories, potential weight gain and related health issues. In practice, it's not so simple, as a review of the scientific evidence on non-nutritive sweeteners published Monday shows. After looking at two types of scientific research, the authors conclude that there is no solid evidence that sweeteners like aspartame and sucralose help people manage their weight. And observational data suggest that the people who regularly consume these sweeteners are also more likely to develop future health problems, though those studies can't say those problems are caused by the sweeteners.

The review, published Monday in the Canadian Medical Association Journal, looked at 37 studies. Seven of them were randomized trials, covering about 1,000 people, and the rest were observational studies that tracked the health and habits of almost 406,000 people over time.

      The parent shouldn't be marked as a troll. Studies have shown that your body reacts to these sweeteners as if they were sugar. Meaning your body will release insulin in anticipation of the food spiking your blood sugar. However that spike never happens so excess insulin ends up causing low blood sugar levels and that signals you to eat more. So yes, using artificial sweeteners will cause you to eat more calories even though they don't have any.

          Sort of. I participated in a class once that did something along these lines as a demonstration of insulin reaction (indirectly, using blood sugar as a metric) to selected foods. Several guinea pig class members, I was one, used a glucometer and recorded serum glucose levels then we ate a bit of three different foods. One guy ate 1/2 a Snickers candy bar, one of ate a plain rice cake and I ate some ham. We waited a bit, took another blood sugar sample. Waited a bit more and took a final blood sugar test. Then we reported on how we felt

          The ham guy, me, had almost no change. The Snickers guy saw his blood sugar rise then drop below baseline, got some energy then crashed a little. The greatest reaction, by far, was the plain rice cake. That person had the greatest rise in blood sugar followed by a greater drop and actually got a little shaky.

          The point of the experiment was to show some misconceptions. Everyone thought the rice cake was healthy and the candy bar and fatty ham was unhealthy.

          Wrong, at least from an insulin flooding standpoint. The rice cake is pure sugar. Starch is just glucose chained together. It turns out that the candy bar, poor nutritionally as it was, had a milder effect because of the fat it contains. Fat seems to blunt the insulin response. Doesn't make the sugar any less, but moderates the insulin reaction. The rice cake hadn't that moderator so it produced the most dramatic reaction.

          That's why restaurants like to start you off with bread while you're perusing the menu. It ain't just being hospitable. They want your blood sugar to be plummeting when you order.

      What I see is people jumping to conclusions that it's the artificial sweeteners that cause the problem, disregarding the simpler explanation of who the main consumers of artificial sweeteners are: People who overindulge, not taste seekers. When their problem of craving carbohydrates doesn't go away; they end up eating more to satisfy their craving. The fries and a Coke becomes two large fries and a Diet Coke.

      So I think the parent isn't just a troll but an insightful troll.

      So far, there is no magic trick that lets people live indulgently and remain healthy. And, deep down inside, everyone knows it.

      We can't make fat people thin with artificial sweeteners. We must give them a reason to want to be healthy. If they see no advantage in prioritizing health over immediate gratification, then why the hell should they change a damn thing?

      We all know we are going to die. We all know that it doesn't really make sense to deny ourselves the joys of life just to gain a few more years of being old and miserable at the end of it. There is a degree to which it is rational to sacrifice quantity of life for quality of life. So, if the quality of a healthy life just doesn't beat the quality of an indulgent one, the decision isn't very hard.

      • I always believed you want to maximize the area under the quality of life curve mapped over time. On one end you probably don't want a highly restricted calorie diet and an extended life, nor do you want a 8k calorie a day diet and die at 34 of a heart attack.

      I had diet coke when it was brand new. Never had diet drinks before. It was a test market so no one in other places had heard of it ("you mean 'Tab'?" they'd ask).

      The thing is, I don't drink it because it's slimming. I drink it because it tastes better. I can't even bother with real Coke, it just tastes wrong, it's too syrupy, whether or not it's real sugar or high fructose corn syrup. I can't even stand diet Pepsi.

      So do you think ordering 2 large Everything pizza's and 4 litres of regular Coke would be better? Would those people get your respect? Or is this just more of the old "lol, fat people, so funny!" trend?

    • I guess the question is really would they have still ordered those pizzas with standard coke. I think 2 large pizzas with 4 litres of coke would have seen them even bigger.

      I have not had any weight problems until recently. I did two things to reduce my calories. First, I cut out my end of day beer. It took me a while to figure out why people enjoyed a beer at the end of the day but for some reason I started the habit. It's relaxing and dulls the aches from the day but it also has a lot of calories. I lost 20 pounds fairly quickly after dropping that habit. Second, I started to keep bottled water around the house. When thirsty I tended to grab whatever I had in a single serve bottle or can. This usually meant a fizzy drink. With bottled water on hand I can grab one of those instead.

      Bottled water comes in handy when there are things contaminate the city water like floods or some idiot put a backhoe through a water main. This does not happen often but when it does and city water is deemed undrinkable then bottled water can get real hard to find. I keep a few bottles in the freezer for when I need to put ice in a cooler, when the ice melts I drink the water from the bottle. Also good for adding thermal mass to the refrigerator and freezer for when the power blinks.

      • An ex-smoker once told me that you get over the craving for a cigarette after one or two puffs, but smoke the rest of it anyway. It's a bit like that with "single serving" anything too - in my anecdotal experience, most 'single servings' are about 30% bigger than you actually need (and when I visit the USA I'm always amazed how much bigger 'single servings' of things are there compared to Europe).

      Actually known since ages.
      The taste of sweetness already increases the insulin level.
      So the less sweet you eat, the lower the insulin level (before actual sugar hits the blood), and the less fat is transported into the fat cells but burned or metabolized.

    • If I want a zero-calorie fizzy drink, I keep my fridge stocked with carbonated bottled water, which has a tiny bit of flavoring added but doesn't add any significant caloric or nutritional impact. Amazon ships Perrier right to my doorstop, but if you can find a source, Talking Rain is good too. I was never a big soda drinker, but I still had cravings for carbonated drinks on occasion.

      Some people don't like the unsweetened drinks, as they're probably an acquired taste, but I absolutely love them.

    Can anyone say confounding by indication? In the same way that people who get a lot of EKGs are at much higher risk of having a heart attack, people who consume artificial sweetners are at increased risk of obesity.

    No one would suggest that getting an EKG increases your risk of heart attacks but people who get a lot of them are certainly at a much, MUCH higher risk of heart attacks. That is because if you have risk factors and complain of chest pain and shortness of breath to a doctor, she will send you for an EKG. In the same way, people self select to consume artificial sweetners if they are fat.

      However there are some (admittedly contradictory) experiments with rats showing that consuming artificial sweeteners can cause obesity.
      Some people prefer Diet Coke because they think regular Coke is too sweet. I agree that most Diet soda consumption is by overweight people trying to cut calories, however.

            Of course they have loads of fat and carbs in them, in addition to heaping amounts of sugar. That's a bad recipe for your general health, but the sticky gooey carbs also wreak havoc on your teeth. It can be a lot worse than soda, because it tends to stick around between your teeth, whereas soda gets washed away by saliva relatively quickly.

            Also, don't swirl the soda around in your mouth, drink it straight down if you must.

    • EKG is diagnostics. Artificial sweeteners are also used preventatively. I see a culture around them without relation to obesity. E.g. North Germans will find aspartame on every restaurant table, the Dutch will look at you with a confused expression when you ask for it. Southern Europe and SE Asia generally give you what you ordered the first time round, the USA and parts of Eastern Europe you'll get confirmations if you want diet, zero, out whatever the latest coke trend is.

    My understanding is that eating something sweet causes an insulin rush (actually, merely the taste of sweetness on the tongue triggers this, you don't even have to swallow it.) If the insulin arrives, and finds no real sugars in the bloodstream, this is like crying wolf. Eventually the insulin stops responding to the sweetness trigger, which is 'insulin resistance.' This causes real sugar to linger in the bloodstream longer before it's processed, although I forgot how that leads to obesity; probably a secondary metabolic pathway converts the 'leftovers' to fat.

    • by mentil ( 1748130 )

      Think I remembered. An insulin rush causes one to be hungry, this is why diabetics who inject insulin have to resist the urge to eat that it creates. Thus, artificial sweeteners make one eat more since they create hunger but no satiety.

      The prevalent theory is leptin resistance. The point at which the body feels like it's at its appropriate level of fat slowly goes up.

      There's also a possibility that insulin resistance wrecks havoc in the hypothalamus, which ultimately leads to unfixable obesity.

      The study itself is also not useless even if the link is the result of behaviour as it shows a measurable way of identifying people's destructive behaviours. There's also a question of justification in the behaviour, e.g. weight gain caused by increased unhealthiness due to the incorrect justification that since sugar is now cut out of me coffee I can eat another

    It could be a lifestyle problem. I know that in my case I started with sugar cola, then switched to diet because I was getting too much sugar, so much I was starting to show off early signs of diabetes mellitus. Then now I am trying to switch off to water (more difficult than you think - I have now bouts of water consumption and bouts of soda without sugar - bad habits are hard to shake. On the other hand my weight is dropping).

    For many people the alternative is not healthy lifestyle with diet soda and healthy lifestyle without, the alternative is unhealthy lifestyle with lotta sugar and sugary drink OR unhealthy lifestyle with diet cola , that is slightly less sugar. As such , yes people consuming artificial sweetener soda seem to are more likely to get lifestyle related disease... But the alternative may actually be they get those disease earlier if they consumed sugary drink instead.
