Sugary Drinks Linked to Global Rise in Diabetes, Heart Disease

“This replicates and reinforces what we already know about sugar-sweetened beverages,” he said, “but the findings highlight their severe costs on health and productivity, especially in Africa and Latin America.”

The study detailed intriguing patterns in the consumption of sugary drinks. For example, researchers found that men had modestly higher rates of soda consumption than women. Intake was higher among the well-educated, especially in sub-Saharan Africa, South Asia and Latin America. In the Middle East and North Africa by contrast, the study found that soda consumption was higher among adults with comparatively lower levels of education.South Asia, Southeast Asia and East Asia had the lowest rates of excess cardiovascular disease and Type 2 diabetes linked to sugary drink consumption, the study found, though the authors noted that the data did not include sugar-sweetened tea and coffee, items that are popular in those parts of the world.

Laura Lara-Castor, a nutritional epidemiologist at the University of Washington and another lead author of the Nature study, said the higher rates of consumption among educated adults in sub-Saharan Africa reflected in part the aspirational lure of soft drink brands associated with Western tastes and style — a result of the sophisticated and well-funded advertising campaigns by multinational beverage companies.

“Consuming these drinks is often a mark of status,” she said.

Despite the study’s grim findings, Dr. Lara-Castor and the other authors said the data also contained reasons for hope. Soda consumption in Latin America and the Caribbean is already beginning to decline, thanks in part to policies like soda taxes, marketing restrictions and package labels that seek to educate consumers about the dangers of products high in added sugar. (In the United States, consumption of sugar-sweetened beverages has dropped since its peak in 2000 but those declines have largely plateaued in recent years.)

More than 80 countries have adopted measures aimed at decreasing sugary drink consumption.

Paula Johns, executive director of ACT Health Promotion, an advocacy group in Brazil, said the Nature study showed that education alone was not enough to dampen consumer zeal for sweetened drinks. In recent years, she said that Brazil had adopted a number of policies that are beginning to dent the nation’s love affair with highly processed food and sugary drinks. They include better school-meal programs, bold front-of-package warnings and a new excise tax on beverages with added sugar.

“There’s no magic bullet,” she said. “But all these policies, taken together, help send the message to the public that sugar-sweetened beverages are really bad for your health.”

Common nighttime noise exposure may trigger heart problems, study suggests

NEWYou can now listen to Fox News articles!

Living near heavy traffic could negatively impact your heart health.

A European study, published in the journal Environmental Research, found that exposure to nighttime road traffic noise is linked to changes in the blood, leading to worsened cholesterol and cardiovascular risks.

The researchers considered data from the U.K. Biobank, Rotterdam Study, and Northern Finland Birth Cohort 1966, including more than 272,000 adults over the age of 30, according to a press release.

Nighttime road noise exposure was estimated at all participants’ homes based on national noise maps. Researchers also took blood samples to measure the participants’ metabolic biomarkers for disease, then mapped the link between nightly noise levels and existence of biomarkers.

The study found that people exposed to louder noise at night — especially sounds above 55 decibels — showed changes in 48 different substances in their blood. Twenty of these associations “remained robust” throughout all cohorts.

Exposure to loud noise was associated with increased concentrations of cholesterol-related biomarkers, especially LDL “bad” cholesterol, IDL (intermediate-density lipoprotein) and unsaturated fatty acids.

As noise levels increased, starting at around 50 decibels, cholesterol markers rose steadily, the release stated.

The authors concluded that this study “provides evidence that nighttime road traffic noise exposure from 50 dB upward is associated with alterations in blood cholesterol and lipid profiles in adults.”

Study co-author Yiyan He, doctoral researcher at the University of Oulu in Finland, noted that in this type of research, small effect sizes are expected, and environmental exposures such as traffic noise are “typically modest.”

“Despite this, we observed statistically robust and consistent associations across many biomarkers, especially those related to LDL and IDL lipoproteins,” she told Fox News Digital.

“We also identified a clear exposure-response pattern starting at around 50 dB, suggesting that metabolic changes become more evident as noise levels increase.”

This aligns with public health guidance, as the World Health Organization recommends lower nighttime noise limits at around 40 to 45 dB, Yiyan He added.

“This finding may clarify the association between traffic noise and cardiometabolic diseases,” the researchers wrote. (iStock)

“The 55 dB level is often used as an interim benchmark associated with substantial noise annoyance and sleep disturbance,” she said. “In our study, we observed associations not only at 55 dB, but also indications of effects emerging at around 50 dB.”

The strength and consistency of the cholesterol-related associations were surprising, as these changes are usually “subtle.”

“Instead, we found consistent associations across multiple large European cohorts, which strengthens confidence that the findings may reflect real biological patterns,” Yiyan He went on. “We were also interested to see that effects were minimal below ~50 dB, suggesting a possible threshold-like pattern.”

The researcher noted that these findings were consistent across genders, education levels and obesity status.

The study was restricted to White Europeans, which posed a limitation. There was also a lack of information on the fasting status in the UK Biobank.

“Fasting can influence levels of certain metabolites, particularly fatty acids,” Yiyan He said. “However, based on UK Biobank documentation, fewer than 10% of participants were fasting for at least eight hours, and our main findings focused on cholesterol-related biomarkers, which are generally less sensitive to short-term fasting.”

The researchers also lacked information on bedroom location, indoor noise exposure and time spent at home.

“These factors may introduce non-differential exposure misclassification,” Yiyan He said. “Additionally, noise exposure estimates were based on participants’ temporary residential addresses at the time of blood sampling, without considering the duration of residence.”

“Many of these limitations would tend to bias results toward the null, so the consistent associations we observed remain noteworthy.”

Based on this latest research, Yiyan He noted that nighttime noise is a “health-relevant exposure,” not just “an annoyance.”

“Our findings suggest that nighttime traffic noise may subtly but consistently affect metabolic health,” she said. “While the changes in cholesterol and lipid levels for any one individual are small, traffic noise affects a very large number of people, which means the potential public health impact could be substantial.”

The researcher recommends taking measures like improving sound insulation, using noise-reducing strategies and placing bedrooms on the quieter side of the home when possible.

“Because sleep is a key pathway linking noise to health, protecting the nighttime sleep environment is especially important,” she added.
