Risks of diet soda and lack of sleep

Researchers recommend less diet soda and more sleep based on the findings of two studies. First, an intriguing study involving researchers in New York and Miami questions the risk factors of diet sodas

Seventeen years ago, researchers began the study asking 2,500 people how much and what kind of soda they drank.

Researchers found that over the years daily diet soda drinkers developed a 60% increased risk of blood clots, stroke, and heart attack.

"We found diet soda or dietary soda increased risk of vascular events by 55 to 60%," said Dr. Mehta from the University of Pennsylvania Medical Center.

The study is small, and didn't take into account other possible factors like family history which influences heart attacks and strokes.

Experts caution the research is not enough to say that daily drinking of diet soda increases chances of a heart attack or stroke.

Regular drinking of diet sodas has already been found to increase a person's chance of pre-diabetes. The study will yield more information in future years.

"It's a very early step in the study of diet soda and cardiovascular disease, and I don't think anyone should make changes just on this report alone, but do keep in mind, if you're thinking about a diet choice, water is definitely the best solution," said Dr. Walter Willet.

Sleep and colon cancer risk

A study from the Case Western University School of Medicine in Ohio focuses on colon cancer.

Colonoscopies are a way to protect and catch early cancers, researchers now believe colonoscopies could be even more important for individuals who average less than six hours of sleep a night.

People who sleep less than 6 hours a night have a 50% higher increase of colon cancer opposed to people who average more than seven hours a night.

The study published in the journal Cancer also states that although lesser amounts of sleep are implicated in raising the risk of diabetes and heart disease, it's the first time the lack of sleep has been seen in a risk of cancer.
