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.

Adding Sugar Increases Cardiovascular Events

February is National Heart Health Month. In honor of heart health, and Valentine’s Day, this post is about cardiovascular disease

In this study published in JAMA Internal Medicine in 2014 researchers looked at the effect of added sugar in the American diet and its relationship to cardiovascular disease. Participants who consumed 17-21% of calories from added sugar had a 38% higher risk of cardiovascular mortality, compared to those who only consumed 8% of calories from added sugar. For those who consumed 21% or more of calories from added sugar, the relative risk was doubled.

Much of the added sugar in the American diet is from soda, other sources include desserts, fruit juices and candy. Just one soda a day constitutes 7% of the total calories of a 2000 kcal/day diet.

The reason for increased cardiovascular risk with increasing sugar intake is probably due to several causes, such as obesity, increased blood pressure, worsening cholesterol, and higher inflammation in the body.

This is a robust study which looked at data from the National Health and Nutrition Examination Survey (NHANES) which is felt to be a nationally representative sample of US adults. It provides more solid evidence of the harms of sugar and simple carbs to cardiovascular health. Happy Valentine’s!

Let’s Help Prevent Diabetes in Women-Just Say No to Soda for 2018 Part 3

On Wear Red Day 2018, we will review a recently published study that examined the relationship between beverages, both artificially sweetened and sugar-sweetened, and subsequent development of diabetes, in a group of menopausal women. This is our third recent post regarding the ill effects of drinking soda.

The research group examined data from the Women’s Health Initiative, a massive study of more than 90,000 women spread out at over 40 clinical centers throughout the US. Nearly 65,000 women were eventually part of this prospective observational study, with over 8 years of follow-up on average.

Participants were queried about their intake of artificially sweetened beverages, sugar-sweetened beverages, and plain water, via questionnaires. Subjects were assessed for diabetes at enrollment, and at annual follow-up.

Even when researchers controlled for other risk factors such as body mass index or total energy intake, their analysis showed both artificially sweetened beverages and sugar-sweetened beverages were associated with an increased risk of developing diabetes, in this group of post-menopausal women.

Both artificially sweetened and sugar-sweetened beverages showed a dose-dependent increase risk of diabetes. The more soda one drank, the higher the risk of developing diabetes.

One of the most interesting “take-home messages” from this study was that while the risk of developing diabetes was a bit lower in the artificially sweetened group, compared to the sugar-sweetened group, there still was an increased risk. This casts doubt over whether or not artificially sweetened beverages are a safer alternative to the sugar-sweetened ones. Both should be avoided.

Data from the American Heart association show that adults with diabetes are two to four times more likely to die from heart disease than those without diabetes. In addition, of those 65 and older with diabetes, 68% will die from some sort of heart disease. So on Wear Red Day 2018 let’s take a step in avoiding diabetes and heart disease by eliminating or avoiding entirely soda, both the artificially and sugar-sweetened varieties.

Just Say No to Soda for 2018- Part II

In our second post regarding sodas and soft drinks, we will review research from China which examines the association between sugar-sweetened beverages and the development of Type 2 Diabetes.

The research group pooled data from 8 studies published between 2004 and 2014. This comprised over 286,000 participants. Of the 8 studies, one was from Asia, two from Europe, and five from the US. In general, the studies included in the meta-analysis were considered to be of “high-quality”.

Researchers found that those subjects with a higher-intake of sugar-sweetened beverages had a 30% greater risk of developing Type 2 diabetes. When the data was adjusted for body mass index, the increased risk for developing Type 2 diabetes continued to be significantly positive, at 26%. The follow-up period varied from 5 to 20 years.

This is a compelling study, with a huge number of subjects, spread out over three continents, and included both men and women.

The statistics for Type 2 diabetes in the US are staggering. According to the CDC’s National Diabetes Statistical Report approximately 30 million people in the US have diabetes, making up more than 9% of the population. Complications of diabetes include cardiovascular disease (heart attacks and strokes) and kidney disease. It is estimated that the cost of diabetes in the US in 2012 was $245 billion.

US per capita soda consumption is approximately 41 gallons per person. While this is a substantial decrease from the 1998 peak consumption of 53 gallons per capita, it still represents nearly 500 cans of soda per year for the typical American. These are calories which are devoid of nutritional value, but do substantially increase your risk of Type 2 diabetes. Cutting back or eliminating soda for 2018 might go a long way towards improved health, and may reduce your risk of developing diabetes in the future.

Just Say No to Soda for 2018- Part I

As 2018 begins a common inquiry from patients at the start of a new year is what can be done to improve health going forward. Often these questions fall into discussion about proper diet or exercise regimens, or some combination of these. The onset of a new calendar year gives us another opportunity to reflect on what we can do to improve our overall health status.

One area of diet that offers a fairly simple and painless way to better health is to limit or eliminate soda (aka soft drinks), both sugar-sweetened and artificially sweetened.

A study from 2016 supports the limiting of sodas. Korean researchers looked at the association of both sugar-sweetened and artificially sweetened beverages with the risk of development of hypertension. The research group identified six studies, with over 246,000 participants, for their analysis of sugar-sweetened beverages and hypertension. For artificially sweetened beverages and hypertension, a total of 4 studies involving over 227,000 subjects were identified. Most of the studies were conducted in the US, while one was conducted in Spain. Most of the studies included were considered to be of “high quality”.

The age at initiation into the study ranged from 18 to 84 years, while the duration of follow-up ranged from 4 to 38 years. Both men and women were included. Food frequency questionnaires were used for dietary assessments.

What the researchers found was a positive association between both sugar-sweetened beverages and hypertension, and artificially sweetened beverages and hypertension as well. More telling, when the lowest intake groups for sugar-sweetened beverages and artificially sweetened beverages were compared to the highest intake groups, it was found that each additional serving of sugar-sweetened beverage per day was associated with an 8% increased risk of hypertension, while each additional serving of an artificially sweetened beverage per day was associated with a 9% increased risk of hypertension. When researchers analyzed the groups based on gender, body mass index, and duration of follow-up period these positive associations continued to hold.

Recent figures indicate Americans consume an average of nearly 500 cans of soda each year. The US is second only to Argentina in per capita soda consumption. 500 cans of soda per year is a staggering total. Cutting back or going soda-free may be a great first step in making 2018 a healthier year for you.

Soda May Cause Worsening of Osteoarthritis in Men

In a study published in the BMJ Open, researchers found that the consumption of soft drinks may be associated with an increased progression of osteoarthritis (OA)  of the knees in men. Researchers examined data from the Osteoarthritis initiative, which was started in 2002 by the National Institutes of Health.

Data from over 2000 participants was examined. X-rays of the knees were taken to evaluate the joint space narrowing in patients, over a course of four years.

Results of the study showed that increased soft drink intake was associated with an increasing rate of OA progression in the knees of men. Interestingly, this relationship did not hold for women. The research group also looked at fruit juice intake and OA progression, and no association was found.

Diet sodas were not examined as part of this particular study. It would be helpful to know if diet sodas were better, worse or the same relative to regular soda. It would also be helpful to know if discontinuation of soda led to improving osteoarthritis status. These may be areas of further research. In any case, this study provides yet another reason to cut back or eliminate sodas entirely, particularly in men.

Soft Drinks, Asthma and Adults

This is the third and final post in recognition of World Asthma Day, Tuesday May 2nd. This post looks at research from the University of Adelaide in South Australia. In particular, the researchers examined the relationship between soft drink consumption and asthma as well as chronic obstructive pulmonary disease (COPD) among a sample of adults in South Australia.

Using a random sample of South Australians phone interviews were conducted with adults ages 16 and older, with a mean of 47 years. In all, nearly 17,000 adults were interviewed.

Respondents were questioned regarding any diagnosis of asthma that was associated with symptoms over the past year, or use of typical asthma medications over the past year. Respondents were similarly queried regarding COPD diagnosis. Soft drink intake was associated by asking about the amount of soft drinks and sports drinks consumed in a typical day.

Results showed that higher levels of soft drink consumption were associated with a higher prevalence of asthma and COPD. Respondents who drank a half liter or more of soft drinks each day had a substantially higher prevalence of asthma (14.7%) compared to those who did not consume soft drinks (11.9%) A similar relationship was seen in COPD where those who drank a half liter or more of soft drinks each day had a prevalence of asthma of 6.0%, compared to only 4.2% in those who did not consume soft drinks.

In the U.S. the CDC estimates 1 in 12 adults has asthma. Women are more likely than men to have asthma. Given these statistics moderating our soft drink intake seems like a simple way to potentially limit one’s risk of asthma.

Sugary Beverages, Asthma and Children

This is the 2nd post in recognition of World Asthma Day, Tuesday May 2nd. This post highlights research from The Netherlands. Researchers took data from the Prevention and Incidence of Asthma and Mite Allergy (PIAMA) birth cohort. For the PIAMA project pregnant mothers were recruited from the general population in The Netherlands, for children born in 1996/1997. Parents were asked to complete questionnaires each year until the children were 8, then again at age 11. The children completed a questionnaire themselves at age 11 as well.

 

For this cross-sectional study, 2651 children completed their questionnaires. This included questions regarding consumption of six different beverages including diet drinks, energy drinks, 100% fruit juice, sports drinks, sugar added drinks (including soda), and sweetened milk products. Concurrently, parents completed a questionnaire that included questions about asthma diagnosis and symptoms. 

Results of the study demonstrated that high consumption of 100% fruit juice, sugar added drinks (including soda), and high total sugar containing beverages in general was associated with increased asthma in children. In particular, as the consumption of 100% fruit juice and total sugar containing beverages went up, the risk for asthma increased as well.

The CDC estimates 10% of all children in the U.S. have asthma. The highest rate of asthma is 17% in non-Hispanic black children. Boys are more likely to have asthma than girls. With statistics this alarming, cutting back on sugar containing beverages seems like a simple way to help limit asthma in our children.
