Why is Diet Soda Bad For You? The
Truth About Diet Drinks
Diet Soda – What Exactly is it?
Diet sodas are carbonated
beverages.
Instead of sugar,
they are sweetened with artificial sweeteners like aspartame, cyclamate,
saccharin, acesulfame-k or sucralose.
These drinks are calorie free,
which technically should help people lose weight and prevent
sugar-related diseases like metabolic syndrome and diabetes.
1. Diet Soda and The Metabolic
Syndrome
The metabolic syndrome is a group
of risk factors for disease that often occur together and raise your risk of
diabetes, stroke and heart disease.
It is defined as having at least
three of the following:
• Abdominal obesity (belly
fat)
• High fasting glucose
• High triglycerides
• Low HDL cholesterol
• Elevated blood pressure
In a study published in the
journal Circulation in 2008, which followed 9.514 people for 9 years, drinking
artificially sweetened beverages was associated with a 34% greater risk of
developing the metabolic syndrome (1).
Another study found a 36%
increased risk of metabolic syndrome and a drastically increased risk of
diabetes in diet soda drinkers (2).
Bottom Line: Observational studies show a correlation between diet soda and
the metabolic syndrome, which can lead to serious diseases.
2. Diet Soda, Depression and
Preterm Delivery
There is an association between
diet soda and depression
In a study of 263.925 adults aged
51-70, individuals who drank soda were 30% more likely to be diagnosed with
depression over a period of 10 years.
The link was stronger for diet
soda than regular soda (3).
Diet soda is also associated with
preterm delivery.
In a study of 59.334 pregnant
women in Denmark, 1 serving per day of diet drinks was associated with a 38%
increased risk of preterm delivery. 4 servings per day increased the risk by
78% (4).
Bottom Line: Diet soda consumption is strongly associated with both
depression and preterm delivery.
3. Diet Soda and The Risk of Type
II Diabetes
Type II diabetes has increased at an alarming rate
in the past few decades and now afflicts about 300 million people worldwide.
This disease is highly associated
with obesity and sugar consumption, so some would argue that replacing
sugar-sweetened beverages with calorie-free drinks would help.
However, there is no evidence of
these drinks being helpful against diabetes.
A study of 6.814 individuals aged
45-85 years, daily consumption of diet soda was associated with a 67% increased
risk of type II diabetes (2).
In another study, 66.118 French
women were followed for a total of 14 years. Women who consumed the most diet
drinks had a 121% greater risk of developing type II diabetes (5).
Data analysis from two large
Harvard studies revealed that diet drinks raised diabetes risk in women, but
not men. Each daily serving increased the risk of a diabetes diagnosis by 6% (6).
Bottom Line: The association between diet soda and diabetes is very strong,
especially in women. One study showed more than a doubling in risk.
4. Diet Soda, Obesity and Weight
Gain
The main reason people switch to
diet drinks is to cut back on calories in order to lose weight.
Unfortunately, it doesn’t seem to
work.
In a study of 3.682 individuals
from San Antonio, Texas, consumption of diet soda was associated with double
the risk of becoming overweight or obese (7).
Other studies determine that drinking
diet soda can make you fat, leading to obesity and its associated problems. For
example, one study found that individuals who drink a diet soda two or more
times a day had a five times increase in waist circumference over a period of
10 years compared to individuals who did not drink any diet soda. The reason
for the association between diet soda and weight gain was previously unknown.
However, researchers at the Institute of Food,
Nutrition, and Health in Zürich, Switzerland recently assessed the impact of
dietary energy (sugar) on gut microbial communities (microbes in the
intestines) and metabolism.
According to the study, consuming high amounts
of fructose (a type of sugar), artificial sweeteners, and sugar alcohols
(another type of low-calorie sweetener) significantly changed the microbes in
the gut that are responsible for signaling satiety and for metabolism. Additionally,
drinking artificially sweetened diet soda can make your body crave sugar.
In other words, drinking diet soda causes your
body to think that you are never full and to slow down your metabolism, both of
which can lead to obesity.
As reported on Today Health,
Amanda Payne, PhD and lead author of the research, comments, “An evolution of
the gut flora to this new sweetener-rich environment has a potential to
negatively impact our health.”
Payne, herself, says that she tries to stay
away from foods that might damage the balance of the microbes in her gut:
“I will say from a personal
perspective that I don’t drink sodas–diet or regular–and I rarely eat processed
foods, especially if they have high-fructose corn syrup listed on their label.”
Diet soda in large quantities negatively
impacts the composition of the microbes in the intestines
Bottom Line: Observational studies show a strong link between diet soda and
obesity and drinking diet soda can negatively affect your metabolism and your
ability to feel satisfied from eating reasonable amounts of healthy foods.
5. Diet soda is loaded with
artificial sweeteners and chemicals that can be harmful to your body. Most diet sodas are sweetened with at least one of these sugar
substitutes: acesulfame potassium (marketed under the brand names, Sunett®,
Sweet One®), aspartame (Equal®, NutraSweet®), or sucralose (Splenda®). And, yes,
they are approved by the FDA, but for the past few decades, scientists have
studied the effects of artificial sweeteners on both animals and humans. The
scientific studies vary significantly: Some show no conclusive, harmful effects
to humans, while other studies, mostly on laboratory rats, link these sugar
substitutes to cancers, tumors, thyroid issues, and — ironically — even weight
gain. According to the National Cancer Institute, laboratory rats that were
given cyclamate and saccharin had higher rates of bladder cancer. This led
the FDA to ban cyclamate in the United States in 1969. Aspartame was linked to
lymphoma and leukemia in rats at very high doses (eight to 2,083 cans of diet
soda daily).
Bottom line: Although aspartame and other sweeteners including acesulfame
potassium, sucralose, and neotame, are still legally considered safe for humans
to consume, is it really worth the risk to your health?
5. Diet sodas can cause tooth
decay. This one comes from my sweet
hubby the dentist. He says without exception whenever he has a patient with
rampant tooth decay they are a soda drinker. And surprisingly many are diet
soda drinkers. His explanation is that soda (especially if sipped through out
the day) changes the acidic balance in the mouth allowing those organisms that
cause tooth decay to multiply and flourish. His advice if you must drink soda
is to drink one thinking of it as a dessert and immediately go brush your teeth
when you have finished.
Bottom line: One of the worst things you can do for your teeth is to buy a
giant soda (yes even if it is diet) and sip it throughout your day. You are
bathing your teeth in disease promoting solution.
Well I don’t know if I have
convinced you to eliminate or at least cut back on the drinking of diet soda in
your every day life but for this next week FOR
