Study unravels health impact, interplay of diet soft drinks and overall diet

29.03.2012
Are diet sodas good or bad for you? The jury is still out, but a new study sheds light on the impact that zero-calorie beverages may have on health, especially in the context of a person’s overall dietary habits.
For the average person, the scientific evidence can seem confusing. A number of studies have implicated diet beverage consumption as a cause of cardiovascular disease. However, others have suggested such drinks may be a viable tactic for people who are trying to lose or control their weight.

Either way, most previous research has tended to focus either on people’s drinking patterns and preferences, or their overall dietary habits – in other words, most studies have failed to tease apart how those two aspects interact to affect people’s health.

To address this problem, a new study from the University of North Carolina at Chapel Hill examined not only people’s beverage consumption patterns but also the diets of those who consume diet and sugar-sweetened beverages. The findings appear in the April issue of the American Journal of Clinical Nutrition.
Kiyah Duffey, Ph.D., study author and research assistant professor of nutrition at the UNC Gillings School of Global Public Health, said that similar to previous studies, the new analysis found that people who consumed diet beverages tended to be less healthy than people who did not consume them.

“However, there was an important interplay between overall diet and what people drink,” Duffey said. “It is important that people consider the entirety of their diet before they consider switching to or adding diet beverages, because without doing so they may not realize the health benefits they were hoping to see.”

Researchers studied data collected over 20 years from more than 4,000 young adults who participated in the Coronary Artery Risk Development in Young Adults (CARDIA) study.
In terms of eating habits, participants fell into two groups: people who ate what researchers dubbed a “prudent” diet (one with more fruit, fish, whole grains, nuts and milk) and individuals who consumed a “western” diet (which had higher amounts of fast food, meat and poultry, pizza and snacks).

People who were healthiest tended to be those who ate a prudent diet and did not consume diet beverages. They had a lower risk of high waist circumference, high triglyceride levels and metabolic syndrome (22 percent, 28 percent and 36 percent lower, respectively, than people who ate a western diet and did not drink diet beverages). But the second healthiest group was individuals with a prudent diet who also consumed diet beverages.

In contrast, individuals who consumed the western diet had increased risk of heart disease, regardless of whether or not they drank diet beverages.

The UNC researchers found that many dietary factors contributed to a person’s overall health. Without taking diet beverage consumption into account, people who ate the prudent diet had significantly better cholesterol and triglyceride profiles and significantly lower risks of hypertension and metabolic syndrome than those who ate the western diet.

Duffey added: “Our study confirms the recommendations of the American Diabetes Association and many weight-loss programs, which suggest people drink these beverages as a way to cut calories and lose or control weight, but only in the context of the whole diet.”

The new study is titled “Dietary patterns matter: diet beverages and cardiometabolic risks in the longitudinal Coronary Artery Risk Development in Young Adults (CARDIA) Study.”

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
