Heart Health

Scientists have been studying the relationship between obesity and metabolic risk factors for decades. One specific relationship being evaluated is the relationship between sugar consumption and cardiovascular disease.

Overall, the current literature suggests that singling out fructose as a contributor to cardiovascular disease is unfounded. Previous studies have simulated unrealistic situations that are unable to garner high generalizability. A limitation of many studies conducted to assess heart health and fructose consumption is that fructose is consumed alone and in very large amounts. Moreover, most experts agree that when consumed in normal amounts in the human diet, there is nothing unique about fructose consumption and health outcomes.  For example, one 10-week study that examined the relationship between high consumption of fructose and high cholesterol or high blood pressure concluded that “…consumption of sugars up to the 90th percentile population consumption level does not adversely impact cholesterol, LDL, blood pressure or glucose in the context of a well-designed, supervised, mixed nutrient diet program.” According to the authors, this study was the only one simulated free living environments that included regular consumption of sugar in addition to fructose. Researchers have also found that fructose does not adversely affect blood pressure. In a 2013 systematic review, Wang et al., found no link between fructose consumption and post-meal triglyceride levels, even when participants consumed high amounts of fructose.

It is important to note, however, that there is strong evidence to suggest that consuming excessive amounts of any energy dense nutrient, including added sugar, can increase the risk of cardiovascular disease.

Study Summary of “Adverse effects of fructose on cardiometabolic risk factors and hepatic lipid metabolism in subjects with abdominal obesity”

For your information, a study entitled “Adverse effects of fructose on cardiometabolic risk factors and hepatic lipid metabolism in subjects with abdominal obesity” was recently published in the Journal of Internal Medicine. The purpose of this study by Taskinen et al. was to determine the effects of fructose on liver fat development, body composition, dietary […]

Early Life Fructose Exposure and Its Implications for Long-Term Cardiometabolic Health in Offspring

A review was recently published in Nutrients which examined the relationship between early life exposure to fructose and cardiometabolic outcomes in offspring. Reviewers cited a number studies which associated fructose intake with various health outcomes such as insulin resistance, elevated low density lipoprotein cholesterol, elevated triglycerides, obesity, type 2 diabetes, cardiovascular disease, non-fatal myocardial infarction, and […]

Fructose as cause of metabolic syndrome is poorly supported

In a recent paper, Perez-Pozo et al. concluded that high doses of fructose raise blood pressure and cause features of metabolic syndrome, and that fructose may therefore have a role in the current epidemics of obesity and diabetes.

Postulated Fructose Influence on Myocardial Infarction is Unconvincing

In a recent paper, Gul et al. suggested that increased fructose concentration induces the aging process and myocardial infarction through production of advanced glycation endproducts (AGEs), however, their supporting evidence is unconvincing.

Methodological problems invalidate sugars differences

In a recent paper, Le et al. reported finding differences between the two most commonly used sweeteners in the US, concluding that “compared with sucrose, HFCS [high fructose corn syrup] leads to greater fructose systemic exposure and significantly different acute metabolic effects.” Evidence in support of this conclusion was unconvincing, however, due to significant deficiencies in the experimental design.
