Science Briefs

Public health policies should focus on promoting a healthy lifestyle that includes physical activity, fresh fruits and vegetables, and a moderate caloric intake, rather than targeting fructose in the diet. This is the conclusion of two recent publications by researchers from the University of Lausanne, Switzerland, which look at the scientific basis behind claims that fructose is toxic. This Science Brief is based on those publications.
While very low carbohydrate (ketogenic) diets are popular with those trying to lose weight, there are concerns that such diets may not support the desire for exercise. This hypothesis was investigated by a US research team at Arizona State University.

A long-term study has found that children given breakfasts with a low glycaemic index (GI) tend to reduce their daily energy intakes by 60 kcal on average. The modest energy reduction, if maintained, could have a significant impact on obesity risk.

Low-carbohydrate, high-protein diets (an example of such a diet could be the Atkins diet), are popular for weight control. Short-term intervention studies suggest that these diets produce a similar weight loss to traditional high-carbohydrate, moderate-protein diets. However, a large observational study has suggested that low-carbohydrate, high-protein diets may not be healthy in the long run.

Weight loss diets that restrict dietary carbohydrates are popular with slimmers but may have a harmful effect on gut health, according to Scottish researchers.

Many people experience difficulty in getting off to sleep. Scientists have shown that carbohydrate foods with a high Glycaemic Index (GI) may induce a quicker sleep onset.

High consumption of soft drinks sweetened with sugar has been viewed as a cause of obesity. However, data from a longitudinal UK study, does not support this association.

A new US study shows that high-fructose corn syrup (HFCS) used to sweeten certain beverages has a similar impact on hunger and satiety as sucrose.

The direct effects of drinking beverages with added sugar or other caloric sweeteners on bodyweight are difficult to discern. A meta-analysis of randomised controlled trials, published in the journal Obesity Reviews, calls for further robust research into the effect of reducing intake of such beverages by overweight individuals.
