MedicalResearch.com Interview with: Kimber L. Stanhope PhD RD Department of Molecular Biosciences School of Veterinary Medicine University of California Dr. Bettina Hieronimus PhD Institute of Child Nutrition Max Rubner-Institut, Federal Research Institute of Nutrition and Food Karlsruhe MedicalResearch.com: What is the background for this study?   Response: Sugar consumption is associated with increased body weight and other metabolic diseases. Fructose in particular seems to be detrimental to health as it causes higher increases in blood lipids compared to glucose. Our study assessed the effects of sugar consumption on cardiometabolic risk factors. We compared the effects of consuming glucose, two different doses of fructose or high fructose corn syrup (HFCS) with a non-caloric sweetener. Our subjects were healthy young individuals who drank three sweetened beverages per day over the course of two weeks.

MedicalResearch.com Interview with: Zhila Semnani-Azad, Ph.D. Candidate  Department of Nutritional Sciences Faculty of Medicine, University of Toronto Toronto, ON, Canada MedicalResearch.com: What is the background for this study? Response: Dietary fructose-containing sugars have been suggested to be an important contributing factor to increased metabolic syndrome risk. Several studies have consistently shown a strong association between sugar-sweetened beverages and increased incidence of metabolic syndrome. There is little information, however, on the role of other food sources of fructose-containing sugars in the development of metabolic syndrome.

What are the main findings? Response: In recent years, considerable evidence has accumulated suggesting that excess sugar consumption, e.g. in sugar-sweetened beverages, has been a major driver of the U.S. obesity crisis. Critics of this idea, however, have asked: why did the rise in sugar consumption precede the U.S. obesity crises by a decade or more, and why did obesity continue to rise even after sugar consumption began declining the early 2000s? We modeled the delayed onset of obesity by assuming that diet is a cumulative process that begins in childhood. On average, each age cohort (birth year) has its own specific cumulative exposure to excess sugar in their diets.  The inherent delay in our model links childhood consumption of excess sugar with propensity for adult obesity as an adult. Our model explains a simple process by which excess sugar in diets of children of the 1970s and 1980s could explain the sharp increase of adult obesity that began in the 1990s.

Response: As the evidence has accumulated regarding the health risks associated with sugar-sweetened beverages, I’ve wondered about fruit juices.  Though they have a kind of healthy halo, their main ingredients are the same as sugar-sweetened beverages, sugar and water.  We know that young children drink a lot of fruit juice, and I’ve wondered if older children and adults might switch to drinking more as concern grows about soft drinks and other sugar-sweetened beverages.

MedicalResearch.com Interview with: E. van Eekelen, MSc | PhD Candidate Leiden University Medical Center Dept. Clinical Epidemiology Leiden, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Fatty liver, defined as excess accumulation of fat within the liver, covers a broad clinical spectrum and is the leading cause of chronic liver diseases. It has also been linked to type 2 diabetes and cardiovascular disease. The consumption of alcohol is a well-established risk factor for fatty liver. However, we hypothesized that consumption of non-alcoholic energy-containing beverages also leads to liver fat accumulation. We analysed data from the Netherlands Epidemiology of Obesity (NEO) study, which is a prospective population-based cohort study including non-invasive measurements of liver fat content by magnetic resonance spectroscopy. Besides consumption of alcoholic beverages, sugar sweetened beverages were associated with more liver fat. We specifically showed that replacement of alcoholic beverages with milk was associated with less liver fat, whereas replacement with sugar sweetened beverages was associated with a similar amount of liver fat, even when taking calories into account.

What are the main findings? Response: Childhood obesity prevalence is historically high, with most incident obesity among children occurring before age 5 years. Racial/ethnic and socioeconomic disparities in childhood obesity are already apparent by the first years of life. Latino/Hispanic children in low-income families are at-risk for obesity. Thus, understanding potentially effective ways to prevent childhood obesity, particularly in vulnerable populations, should focus on early life. Sugar-sweetened beverage (SSB) consumption is a modifiable risk factor for obesity and is linked to other adverse health outcomes. Maternal SSB consumption in pregnancy and infant sugar-sweetened beverage consumption in the first year of life are linked to later childhood obesity. We sought to describe beverage consumption in a modern cross-sectional cohort of 394 low-income, Latino families, and to examine the relationship of parental attitudes toward sugar-sweetened beverages with parental and infant SSB consumption.

MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sugar consumption among Americans is above recommended limits and this excess intake may have important health implications. This study examined the associations of pregnancy and offspring sugar consumption, as well as sugar-sweetened beverages, other beverages (diet soda, juice), and fruit consumption with child cognition. This study found that when pregnant women or their children consumed greater quantities of sugar, as well as when women consumed diet soda during pregnancy, this was associated with poorer childhood cognition.  However, children’s fruit consumption was associated with higher cognitive scores.

What are the main findings? Response: The study arose from a previous paper I authored in the Journal of Neuroscience, where we found Adenosine receptors in taste. We managed to prove that they were there to amplify sweet signals. This led us to wonder, what about the foods we consume, that would come into contact with these receptors in taste buds. It just happens that a lot of us habitually consume a powerful blocker of adenosine receptors every morning. Caffeine. So is our coffee impairing sweet signals? It turns out when we gave people sweetened coffee containing caffeine, they judged it as less sweet than the same coffee without the caffeine, sampled on a different day. Interestingly, this persisted, and sweet solutions they tested afterwards were still a little less sweet. Finally, just for kicks, we asked them to rate how much caffeine they thought was in either coffee, and how much more alert it made them feel. Turns out, there was no difference. They couldn’t tell which was deacf, and either coffee gave them just as much of an alertness boost. MedicalResearch.com: What should clinicians and patients take away from your report? Response: Readers should consider that they may be altering how their food tastes when consuming coffee. And perhaps also, they could be drinking decaf, and getting just as good a jolt from it (as long as someone else was preparing it for them, so they didn’t know). MedicalResearch.com: What recommendations do you have for future research as a result of this study? Response: We’re interested in how many factors we encounter in our every day lives change our perception, from the foods we’re consuming themselves, to our own bodies. We’re currently looking into how obesity, pregnancy and sleep can change our sense of taste, and the foods we crave. If you’d like to hear more about what we do, you can follow our work on twitter @DandoLab.

What are the main findings? Response: Messages in the mass media have been used in anti-smoking campaigns, but have not be used much for other health-related behaviors.  Sugar-sweetened beverages are major contributors to the obesity epidemic in the United States, so they are an important public health target. In this study we evaluated a brief counter-advertising campaign in a rural area of Tennessee, Virginia, and Kentucky designed to reduce consumption of these beverages.  After the campaign, adults in the area were more wary of sugary drinks, and sales of sugary drinks fell by about 4% relative to changes in a matched comparison area.

What are the main findings? Response: The Mexican government enacted a 1 peso per liter tax on sugar sweetened beverages (SSB) after studies showed that more than 70 percent of the country’s population was overweight or obese, and that in excess of 70 percent of the added sugar calories in the Mexican diet were coming from SSBs. We were interested in learning how purchases of SSBs and other beverages changed in the 2 years after the tax was implemented in Mexico. The Health Affairs study titled “In Mexico, Evidence Of Sustained Consumer Response Two Years After Implementing A Sugar-Sweetened Beverage Tax” found that in the two-year period spanning 2014 to 2015, the tax resulted in a 5.5 percent reduction in the first year and continued to decline, averaging 9.7 percent the second year, with lower socioeconomic households, for whom health care costs are most burdensome, lowered their purchases of sweetened beverages the most. Meanwhile, purchases of untaxed beverages such as bottled water increased 2.1 percent.

MedicalResearch.com Interview with: Dr. Marta Alegret Department of Pharmacology, Toxicology and Therapeutic Chemistry Pharmacology Section School of Pharmacy and Food Sciences University of Barcelona MedicalResearch.com: What is the background for this study? Response: In humans, an excessive intake of sugars has been linked to the development of metabolic disturbances, and therefore to an increase in the risk for cardiovascular diseases. Specifically, increased consumption of simple sugars in liquid form, as beverages sweetened with high fructose corn syrup or sucrose, has been linked to obesity, insulin resistance and type 2 diabetes. However, two questions remain unresolved: what is/are the underlying molecular mechanism(s) linking these metabolic alterations to cardiovascular diseases? Are the adverse cardiovascular and metabolic effects of sugar-sweetened beverages merely the consequence of the increase in caloric intake caused by their consumption? To answer to these questions, we performed a study in female rats, which were randomly assigned to three groups: a control group, without any supplementary sugar; a fructose-supplemented group, which received a supplement of 20% weight/volume fructose in drinking water; and a glucose-supplemented group, supplemented with 20% weight/volume glucose in drinking water.

Many guidelines have methodological issues but it was suspected that the nutritional guidelines were especially problematic. Our study in Annals of Internal Medicine set out to document the issues systematically with respect to sugar intake recommendations from authoritative guidelines.

MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our company surveyed over 3,000 Americans from across the country about their sugar consumption habits and awareness about added sugar in food. What we learned is that while many people are aware of the threat overconsumption of sugar is to their health, they aren’t doing much about it. Why not? They don’t know how and quite often they don’t know how much sugar is contained in certain foods they eat. We have an awareness issue. Two out of 3 respondents answered incorrectly to our questions related to which food item contained more sugar.

MedicalResearch.com Interview with: Margaret A. Brennan Department of Wine, Food and Molecular Biosciences Lincoln University Lincoln, Canterbury, New Zealand MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has been immense consumer attention recently in terms of the reduction of sugar levels in food products. Most of this attention has stemmed from a nutritional understanding that foods high in sugar and easily digested carbohydrates can increase blood glucose levels and hence potentially lead to weight gain, obesity issues, metabolic diseases (diabetes related illnesses) and even Alzheimer’s disease due to up regulation of genes responsible for amyloid like complexation. Our research over the last 10-15 years has tried to investigate the relationship between food composition – food structure / processing – human nutrition. We have developed a deep understanding of how we can regulate the potential glycaemic index of foods by selective use of non-starch polysaccharides, natural sweeteners and texturizing agents to manipulate the rate of starch and carbohydrate digestion. This study clearly illustrates the great potential of the use of certain natural sweeteners in producing reduced sugar consumer products which have the benefit of reducing glycaemic response in individuals. The utilisation of plant based ingredients to manipulate such a a response offers not only the industry but consumers a powerful opportunity to regulate glycaemia and hence associated metabolic orders. The study also illustrates that sugar is important in modern foods in providing the structure and hence textural characteristics we have grown accustomed to as consumers. Again careful selection of ingredients can minimise any potential negative effects on food structure and texture that sugar reduction may have.

Dr. Kuk: Artificial sweeteners are used to help individuals manage their weight, however, individuals who consume aspartame (a type of artificial sweeteners) have worse glucose metabolism than individuals with the same body weight but do not consume aspartame. This observation was only true for adults with obesity. Further, saccharin and natural sugars were not associated with differences in health after considering differences in obesity.
Author Interviews, BMJ, Nutrition, Sugar, Weight Research / 10.03.2016

MedicalResearch.com Interview with: Euridice Martinez Steele  University of São Paulo, São Paulo MedicalResearch.com: What is the background for this study? Response: Several leading health bodies, including the World Health Organization, the Canadian Heart and Stroke Foundation, the American Heart Association, and the US Dietary Guidelines Advisory Committee have concluded that excess added sugar intake increases the risk not only of weight gain, but also of obesity and diabetes, which are associated with a heightened risk of cardiovascular disease, and tooth decay. All reports recommended limiting intake of added sugars. In the US, the USDGAC recommended limiting added sugars to no more than 10% of total calories. To design and implement effective measures to reduce added sugars, their dietary sources must be clearly identified. Added sugars can be consumed either as ingredients of dishes or drinks prepared from scratch by consumers or cook, or as ingredients of food products manufactured by the food industry. According to market disappearance data from 2014, more than three quarters of the sugar and high fructose corn syrup available for human consumption in the US were used by the food industry. This suggests food products manufactured by the industry could have an important role in the excess added sugars consumption in the US. However, to assess this role, it is essential to consider the contribution of manufactured food products to both total energy intake and the energy intake from added sugars, and, more relevantly, to quantify the relationship between their consumption and the total dietary content of added sugars. To address these questions, we performed an investigation utilizing 2009-2010 National Health and Nutrition Examination Survey (NHANES).

DiNicolantonio, PharmD Associate Editor BMJ Open Heart Cardiovascular Research Scientist Saint Luke's Mid America Heart Institute  Medical Research: What is the background for this study? What are the main findings? Dr. DiNicolantonio: We comprehensively reviewed the literature looking at the cardiovascular effects of saturated fat and compared them with refined sugars (sucrose and high-fructose corn syrup).  Our main finding is that saturated fat per se is not necessarily unhealthy.  Importantly, people eat foods, not saturated fat, and depending on what foods are consumed determines if saturated fat associates with health risk.  For example, the consumption of processed meat is associated with an increased risk of cardiovascular disease, whereas dairy is not.  Importantly, the replacement of saturated fat with refined sugars seems to increase the risk of myocardial infarction.  Hence, reducing added sugars should be the main focus rather than reducing saturated fat, as the latter could translate to reductions in healthy whole foods that just so happen to also be high in saturated fat (but also provide other healthy fats).

What are the main findings? Response: The calculations showed that a 40% reduction in free sugars added to Sugar Sweetened Beverages (SSBs) over five years would lead to an average reduction in energy intake of 38 kcal per day by the end of the fifth year. This would lead to an average reduction in body weight of 1.20kg in adults,  resulting in a reduction in overweight and obese adults by approximately half a million and 1 million respectively. This would in turn prevent between 274,000-309,000 obesity-related type 2 diabetes over the next two decades. Policies such as this will reduce cases of overweight and obesity and type 2 diabetes, this will have a major clinical impact and reduce healthcare costs.

Ekaterina Maslova PhD Doctor of Science in Nutrition and Epidemiology Center for Fetal Programming Copenhagen, DenmarkMedicalResearch.com Interview with: Ekaterina Maslova PhD Doctor of Science in Nutrition and Epidemiology Center for Fetal Programming Copenhagen, Denmark Medical Research: What is the background for this study? What are the main findings? Response: From prior studies we know that excessive gestational weight gain (GWG) in pregnancy is associated with complications for both the mother and the child, including gestational diabetes, hypertension, and high birth weight. Understanding the factors that determine gestational weight gain would allow for interventions early on to improve pregnancy outcomes. Dietary intake has been found to influence gestational weight gain in other studies, but evidence is conflicting and still quite limited. In non-pregnant populations a high-protein diet was shown to decrease weight and improve weight maintenance. We therefore hypothesized that a similar relation may exist for gestational weight gain in pregnant women. In this study we had data on dietary intake of more than 45,000 Danish women who were pregnant between 1996 and 2002. We examined the relation between their intake of protein and carbohydrates and the rate of gestational weight gain (in grams per week). We found that women who consumed a high protein-to-carbohydrate (PC) ratio gained less gestational weight gain compared to women with a lower PC ratio in their diet. The results was stronger in women who started their pregnancy already overweight compared to normal weight women. Since a high PC ratio may result from either a high protein intake or low carbohydrate intake, we decided to focus on a component of carbohydrates that may increase gestational weight gain: added sugar. We found that pregnant women with higher intake of sugar gained more weight in pregnancy compared to those who consumed less added sugar. This averaged out to about 1.4 kg (or 7%) higher weight gain across the entire pregnancy.

Controlling hypertension is a major focus of public health initiatives, and dietary approaches have historically focused on sodium. A reduction in the intake of added sugars, particularly fructose, and specifically in the quantities and context of industrially-manufactured consumables, would help not only curb hypertension rates, but would also help address broader problems related to cardiometabolic disease.

UK.MedicalResearch.com Interview with: Professor Aubrey Sheiham Emeritus Professor of Dental Public Health Department of Epidemiology & Public Health, University College London, WC1E 6BT. UK. Medical Research: What are the main findings of the study? Prof Sheiham: There is a robust log-linear relationship of caries to sugar intakes from zero to 10% of sugars as a proportion of total energy intake. Furthermore our analyses showed that sugar intakes of 10%E sugars intake that is currently recommended as an upper limit for free sugars by the WHO and the Scientific Advisory Committee on Nutrition in England would induce a very costly burden of caries in most populations. Second, we found that free sugars* in the diet should make up no more than 3% of total energy intake. Above that level they cause a significant level of tooth decay across the lifecourse of most people in the developed world. Third, we were able to show that despite widescale fluoride use from both toothpastes and drinking water the mean numbers of decayed, missing and filled teeth (DMFT) and decayed and filled surfaces (DFS) for adults increased with sugar use despite the presence of fluoride. *Free sugars are defined by the World Health Organisation Nutrition Guidance Adivisory Group as follows: “Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates.”

MedicalReseach.com Interview with: Quanhe Yang, PhD Division for Heart Disease and Stroke Prevention Centers for Disease Control and Prevention, Atlanta, GA 30341 MedicalReseach.com: What are the main findings of the study? Dr. Yang: The majority of US adults consume more added sugar than is recommended for a healthy diet. On average, Americans consume about 15% of daily calories from added sugar.  About 70% of adults consume more than 10%of calories from added sugar and another 10% consume more than 25% of calories from added sugar. When you compare those who consume 7.5% (lowest quintile) of calories from added sugar with participants who consume between 17%-21% (quintile 4) of calories from added sugar, the latter group has a 38% higher risk of CVD mortality. But the risk of CVD death more than doubles  for those who consume  ≥21% (highest quintile) of calories from added sugar.
