(Press-News.org) Québec, February 8, 2024 - Contrary to popular belief, the benefits of physical activity do not outweigh the risks of cardiovascular disease associated with drinking sugar-sweetened beverages, according to a new study led by Harvard T. H. Chan School of Public Health. Jean-Philippe Drouin-Chartier, professor at Université Laval’s Faculty of Pharmacy, was a co-author.
Sugar-sweetened beverages are the largest source of added sugars in the North American diet. Their consumption is associated with a higher risk of cardiovascular disease, the world’s leading cause of death.
“The marketing strategies for these drinks often show active people drinking these beverages. It suggests that sugary drink consumption has no negative effects on health if you’re physically active. Our research aimed to assess this hypothesis,” says Drouin-Chartier.
For the study, the scientists used two cohorts totalling around 100,000 adults, followed for about 30 years. The data show that those who consumed sugar-sweetened beverages more than twice a week had a higher risk of cardiovascular disease, regardless of physical activity levels.
The study found that even if the recommended 150 minutes of weekly physical activity protects against cardiovascular disease, it’s not enough to counter the adverse effects of sugar-sweetened beverages. “Physical activity reduces the risk of cardiovascular disease associated with sugar-sweetened beverages by half, but it does not fully eliminate it,” says Drouin-Chartier.
The frequency of consumption considered in the study—twice a week—is relatively low but still is significantly associated with cardiovascular disease risk. With daily consumption, the risk of cardiovascular disease is even higher.
For this reason, Drouin-Chartier underlines the importance of targeting the omnipresence of sugar-sweetened beverages in the food environment. This category includes soft and carbonated drinks (with or without caffeine), lemonade, and fruit cocktails. The study did not specifically consider energy drinks, but they also tend to be sugar-sweetened.
For artificially sweetened drinks, often presented as an alternative solution to sugar-sweetened beverages, their consumption was not associated with higher risk of cardiovascular diseases. “Replacing sugar-sweetened beverages by diet drinks is good, because it reduces the amount of sugar. But the best drink option remains water,” explains Drouin-Chartier.
“Our findings provide further support for public health recommendations and policies to limit people’s intake of sugar-sweetened beverages, as well as to encourage people to meet and maintain adequate physical activity levels,” added lead author Lorena Pacheco, a research scientist in the Department of Nutrition at Harvard Chan School.

(BOSTON: Thursday, February 8, 2024) – Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) will award up to US$1.8 million to biotechnology company, Visby Medical, to develop a portable rapid polymerase chain reaction (PCR) diagnostic to detect the presence of the pathogen that causes gonorrhea, Neisseria gonorrhoeae (NG), and its susceptibility to ciprofloxacin, a former frontline oral antibiotic that can no longer treat resistant NG. A rapid result on when ciprofloxacin may be effective could enable physicians to treat gonorrhea patients with confidence, while reserving ceftriaxone, the only antibiotic that remains effective against resistant NG.
GARCHING and OXFORD (8 February 2024) –
The Joint European Torus (JET), one of the world’s largest and most powerful fusion machines, has demonstrated the ability to reliably generate fusion energy, whilst simultaneously setting a world-record in energy output.
These notable accomplishments represent a significant milestone in the field of fusion science and engineering.
In JET's final deuterium-tritium experiments (DTE3), high fusion power was consistently produced for 5 seconds, resulting in a ground-breaking record of 69 megajoules using a mere 0.2 milligrams of fuel.
JET is a tokamak, a design which uses powerful ...
Electronically conducting two-dimensional (2D) materials are currently hot topics of research in both physics and chemistry owing to their unique properties that have the potential to open up new avenues in science and technology. Moreover, the combination of different 2D materials, called heterostructures, expands the diversity of their electrical, photochemical, and magnetic properties. This can lead to innovative electronic devices not achievable with a single material alone.
Heterostructures can be fabricated in two ways: vertically, with materials ...
An eye-catching new study shows just how different the experience of walking home at night is for women versus men.
The study, led by Brigham Young University public health professor Robbie Chaney, provides clear visual evidence of the constant environmental scanning women conduct as they walk in the dark, a safety consideration the study shows is unique to their experience.
Chaney and co-authors Alyssa Baer and Ida Tovar showed pictures of campus areas at four Utah universities — Utah Valley University, ...
Researchers from the University of Cambridge and the British Antarctic Survey have uncovered the first direct evidence that the West Antarctic Ice Sheet shrunk suddenly and dramatically at the end of the Last Ice Age, around eight thousand years ago.
The evidence, contained within an ice core, shows that in one location the ice sheet thinned by 450 metres — that’s more than the height of the Empire State Building — in just under 200 years.
This is the first evidence anywhere in Antarctica for such a fast loss of ice. Scientists are worried that today’s rising temperatures ...
LA JOLLA (February 8, 2024)—Cells in the human body contain power-generating mitochondria, each with their own mtDNA—a unique set of genetic instructions entirely separate from the cell’s nuclear DNA that mitochondria use to create life-giving energy. When mtDNA remains where it belongs (inside of mitochondria), it sustains both mitochondrial and cellular health—but when it goes where it doesn’t belong, it can initiate an immune response that promotes inflammation.
Now, Salk scientists ...
Researchers from Tokyo Medical and Dental University (TMDU) overcome scientific roadblocks and develop a model to assess the biology of the human placental barrier
Tokyo, Japan – During pregnancy, the human placenta plays multiple essential roles, including hormone production and nutrient/waste processing. It also serves as a barrier to protect the developing fetus from external toxic substances. However, the placental barrier can still be breached by certain drugs. In a recent article published in Nature Communications, a team led by researchers ...

A new King’s College London scanning study of 390 babies has shown distinct patterns between term and pre-term babies in the moment-to-moment activity and connectivity of brain networks.
Supported by Wellcome and the National institute of Health and Care Research (NIHR) Maudsley Biomedical Research Centre, this is the first study to analyse how the communication between brain areas changes moment-to-moment in the first few weeks of life.
Published in Nature Communications, the study also found that these dynamic ...
White actors are featured more frequently and more prominently on posters for American-produced films than non-white actors despite recent increases in the representation of actors from other ethnic groups, according to a study published in Humanities and Social Sciences Communications.
Galit Fuhrmann Alpert and colleagues investigated trends in the ethnic diversity of actors featured on over 45,000 posters advertising over 24,000 English-speaking films produced in the USA between 1960 and 2021. Actors were assigned to one of four ethnic groups; white, Black, Indian, or Asian using an algorithm trained on the FairFace image dataset, which contains equal numbers ...

Researchers identify potential way to treat genetic epilepsy by replacing ‘lost’ enzyme
Scientists at the Francis Crick Institute have found a new treatment target for CDKL5 deficiency disorder (CDD), one of the most common types of genetic epilepsy.
CDD causes seizures and impaired development in children, and medications are limited to managing symptoms rather than tackling the root cause of the disease. The disorder involves losing the function of a gene producing the CDKL5 enzyme, which ...
