Sugary Drinks Increase Risk of Cancer

In a study published three weeks ago, researchers from France looked at the relationship between the consumption of sugary drinks and the risk of cancer.

The average American consumes about 45 gallons of soda each year. An average 12 ounce can of soda contains upwards of 40 grams of total sugar, or about nine teaspoons of sugar.

A population-based prospective cohort study was completed with over 100,000 subjects from the French NutriNet-Sante study. Participants were 18 years of age and older, with a predominance of women (79%) to men (21%). Mean age at baseline was 42 years.

The sugary drink group consisted of energy drinks, fruit drinks, sodas, sports drinks, 100% juice drinks, among others. Consumption of sugary beverages was assessed by 24 hour dietary records. Association of beverage intake and risk of overall, breast, colorectal, and prostate cancer was assessed.

The researchers found that there was a positive association between the amount of sugary drink intake, and risk of overall cancer and breast cancer. Also, when looking specifically at 100% fruit juices these were also positively associated with risk of overall cancer.

Interestingly, the researchers did not find an association between artificially sweetened beverage consumption and the risk of cancer.

The researchers suggest several possible mechanisms by which sugary drinks may increase cancers risks. These include obesity, increased visceral fat, higher glycemic index, and increased pro-inflammatory markers.

This is a solid study, which included nearly 80,000 women. This study demonstrates how a simple dietary intervention, in this case limiting sugary beverages including 100% juices, may potentially have a meaningful impact on our health. Perhaps next time you are reaching for a soda, grab a glass of water instead.

Tea Lowers Risks of Oral Cancers

April is Oral Cancer Awareness Month, and in recognition of this today’s post will examine recent research on the consumption of tea and risk of oral cancer.

Statistics from the American Cancer Society estimate about 53,000 Americans will develop oral cavity or oropharyngeal cancer in 2019. It is also estimated that nearly 11,000 will die from these types of cancer. The main risk factors appear to be tobacco use, alcohol, and HPV infection.

A recent study was performed by a group of researchers in China. They performed a review and meta-analysis of 14 case-control studies, examining the role between tea consumption and oral cancers. These studies included participants from the Africa, Asia, Europe and the US.

The researchers discovered that increased tea consumption was associated with a decreased risk of oral cancer. A dose-response analysis indicated that the risk of oral cancer was decreased when the dose and duration of tea consumption was increased. For example, with every cup of tea intake increased, the risk of oral cancer dropped by 6.2%.

Tea is known to contain many bioactive compounds, such as catechins. Catechins are flavonoid compounds, and have antioxidant properties. It is thought that catechins have anti-carcinogenic properties as well, and hence may be one of the compounds in tea that work to lower cancer risk.

The 5 year survival rate of oral cancers is about 65%. Early detection is the key to the survivability from many types of cancers, as is avoidance of known risk factors. Given the results of this study, perhaps consider tea as a healthy beverage of choice.
