Diet Drinks not ‘Diet’ After All

Ana Sandoiu wrote . . . . .

From soft drinks to white bread, almost everything on the menu seems to contain sugar. Although “diet” drinks have been promoted as a healthful alternative to sugar-sweetened beverages, researchers now argue this is not the case.

There are currently numerous campaigns trying to raise awareness of the negative health effects of sugar, particularly on weight gain and obesity.

Sugar is highly pervasive in our diet. Approximately 75 percent of processed foods and drinks contain added sugar.

Additionally, the consumption of sugar-sweetened beverages (SSBs) has increased fivefold since the 1950s.

Numerous studies have pointed to a link between SSBs and cardiovascular disease, metabolic syndrome, and diabetes.

The alternative to SSBs promoted by soft drink companies is the sugar-free, “diet” drink. These artificially sweetened beverages (ASBs) are said to be healthful and prevent weight gain.

But researchers from Imperial College London in the United Kingdom argue otherwise.

Full-sugar versus ‘diet’ drinks

A new commentary on existing ASB research and policy – published in the journal PLOS Medicine – argues that ASBs are just as ineffective in preventing weight loss as their full-sugar counterparts.

The commentary is a collaborative effort between Imperial College London, University of Sao Paulo and the Federal University of Pelotas – both in Brazil – and Washington University in St. Louis, MO.

According to the authors, in the U.K., SSBs make up a third of the total sugar intake among teenagers. In Brazil, they are the second largest source of dietary sugar, and in the United States, SSBs account for almost half of the added sugar in Americans’ diet.

The researchers – led by Prof. Christopher Millett – argue that although SSBs are very high in calories, they contain almost no essential nutrients. Additionally, “convincing epidemiological evidence” has suggested that consuming SSBs increases the risk of being overweight or obese, as well as developing diabetes.

ASBs are becoming more and more popular as an alternative to harmful sugary drinks. By 2008, the number of American children consuming ASBs had doubled, compared with 1999.

Soft drinks, fruit juices, flavored water, and ready-to-drink coffee and tea are all artificially sweetened. Because they taste similar to their full-sugar counterparts and have none of their energy content, ASBs are perceived as healthful, as it is believed they do not trigger any energy compensation mechanisms.

Additionally, “taxes and regulation on SBS and not ASBs will ultimately promote the consumption of diet drinks rather than plain water – the desirable source of hydration for everyone,” mentions Prof. Carlos Monteiro, one of the authors of the review.

Diet drinks a ‘potential risk factor for chronic diseases’

However, researchers explain why the common perception of diet drinks might be wrong.

ASBs can still cause a compensatory mechanism by stimulating sweet taste receptors. This can, in turn, increase appetite and stimulate the secretion of gut hormones. Knowing that ASBs are low in calories might amplify these effects and lead to excessive consumption of other foods.

This chain reaction could lead to weight gain, obesity, and obesity-related complications.

In fact, Millett and team point out that several observational studies and meta-analyses have correlated ASBs with increased body mass index (BMI) and a higher risk of cardiometabolic diseases, such as type 2 diabetes and stroke.

However, observational studies are vulnerable to so-called reverse causality – for example, people with obesity might tend to consume more ASBs because they are trying to control their weight, rather than the ASBs causing the weight gain themselves.

Even so, randomized controlled trials of ASBs have shown either no effect at all on weight loss, or only minor reductions in weight.

The authors warn against the dangers of biased research and conflicting interests. They refer to a systematic review that has shown studies sponsored by beverage companies tend to report positive effects of ASB on weight management.

“The lack of solid evidence on the health effects of ASBs and the potential influence of bias from industry-funded studies should be taken seriously when discussing whether ASBs are adequate alternatives to SSBs,” says Dr. Maria Carolina Borges, first author of the new review.

Finally, while the evidence reviewed does not directly demonstrate that ASBs trigger weight gain or metabolic disorders, it does not show ASBs to be effective for weight loss either.

The authors conclude:

“The absence of evidence to support the role of ASBs in preventing weight gain and the lack of studies on other long-term effects on health strengthen the position that ASBs should not be promoted as part of a healthy diet.

Far from helping to solve the global obesity crisis, characteristics related to ASB composition […], consumption patterns […], and environmental impact make them a potential risk factor for highly prevalent chronic diseases.”

A Vegetarian Dish with Eggplant, Zucchini and Tomatoes Topped with Bread and Cheese


1 medium eggplant. about 2/3 pound
1 onion
2 tablespoons olive oil
1 clove garlic, crushed
2 zucchini
4 large tomatoes
2 tablespoons tomato paste
4 tablespoons chopped fresh parsley 4 fresh basil sprigs


2 slices whole-grain bread
2/3 cup crumbled feta
1 tablespoon olive oi


  1. Trim and discard the stem end of the eggplant and cut the flesh
    into 1/2-inch cubes. Chop the onion. Heat the oil in a large saucepan over high heat, add the onion and garlic, and cook for 1 minute. Add the eggplant, reduce the heat to medium, and cook for 5 minutes, stirring occasionally, until softened.
    2 Meanwhile, cut the zucchini into 1/2-inch cubes. Add them to the pan and continue to cook for another 2 minutes. stirring occasionally until the vegetables start to brown.
    3 Preheat the broiler to high. Dice the tomatoes then add them with the tomato paste to the pan. Stir in 1/3 cup of cold water. Heat the mixture until simmering, cover. and cook over a medium to medium-low heat for 8-10 minutes. Stir in the parsley and transfer to a shallow ovenproof dish.
    4 For the topping. cut the bread into 1/2-inch cubes. Add the feta to a bowl with the bread, then pour in the oil and toss to coat. Sprinkle the topping over the ratatouille and broil for 1-2 minutes. or until the cheese softens and the bread browns. Strip the leaves from the basil sprigs and sprinkle them over the ratatouille before serving.

Cook’s Tip

Don’t worry about salting the eggplant before use. In the past, eggplant cultivars were bitter and had to be salted (known as degorging) to draw out the sour juices, but varieties available in supermarkets

Makes 4 servings.

Study Disputes Weather’s Role in Knee and Back Pain

You might want to think twice the next time you’re ready to blame the weather for your aches and pains, researchers say.

Some people swear that changes in humidity, temperature, air pressure and the like trigger back pain and arthritis. But a team at the George Institute for Global Health in Newtown, Australia said it found no evidence to support that theory.

“The belief that pain and inclement weather are linked dates back to Roman times. But our research suggests this belief may be based on the fact that people recall events that confirm their pre-existing views,” said Chris Maher, director of the institute’s musculoskeletal division.

The study included nearly 1,350 Australians with either lower back pain or osteoarthritis of the knee. The study participants’ pain flare-ups were compared with weather data.

There was no association between back pain/knee arthritis and temperature, humidity, air pressure, wind direction or precipitation, the investigators found.

“Human beings are very susceptible so it’s easy to see why we might only take note of pain on the days when it’s cold and rainy outside, but discount the days when they have symptoms but the weather is mild and sunny,” Maher explained in an institute news release.

Maher is also a professor of physiotherapy at the University of Sydney.

Back pain affects up to one-third of people worldwide at any one time. Nearly 10 percent of men and 18 percent of women over the age of 60 have osteoarthritis, the study authors said in background notes.

Manuela Ferreira, an associate professor of medicine who led the osteoarthritis research, said, “People who suffer from either of these conditions should not focus on the weather as it does not have an important influence on your symptoms and it is outside your control.

“What’s more important is to focus on things you can control in regards to managing pain and prevention,” he concluded.
