Soy milk could reduce risk factors for heart disease, research shows

Soy milk could have great heart health benefits, according to a new study.

Research from the University of Toronto found that drinking soy milk can help lower blood pressure and blood lipids, which are risk factors for heart disease.

The study, which was published in BMC Medicine and funded by the Soy Nutrition Institute Global (SNI) and the United Soybean Board, analyzed 17 randomized control trials and 19 outcomes to determine these health effects.

The findings revealed a moderate reduction in non-HDL cholesterol, which includes all the “bad” cholesterol. The soy milk was also linked to reduced blood pressure and slightly reduced inflammation.

Other health-related outcomes, including glycemic control and kidney function, did not vary between soy milk and cow’s milk.

Most soy milk is classified as “ultra-processed” and has been criticized for containing added sugar, according to an SNI press release.

“But the analysis found that soy milk with added sugar exerted health benefits similar to soy milk without added sugar,” the release stated.

This finding was the most surprising to the research team, according to lead study author Madeline Erlich, PhD.

“Results of the analysis show that in adults, consumption of soy milk both sweetened and unsweetened can improve heart health by lowering blood pressure and cholesterol levels, without affecting markers of inflammation,” she wrote in an email to Fox News Digital.

The researchers sought to understand whether nutrient-dense, plant protein foods like soy milk can be part of a heart-healthy diet despite being classified as “ultra-processed.”

“One in three Americans is now familiar with the term ‘ultra-processed foods,’ even though there is no scientific consensus on the definition,” Erlich said.

“Many foods classified as ‘ultra-processed’ are highly rated by other food classification systems used around the world.”

Registered dietitian and nutritionist Ilana Muhlstein, who is based in Los Angeles, agreed that soy gets a “bad rap.”

“In America, we genetically modify it and overly process it into byproducts like soybean oil, in order to mass-market ultra-processed foods that can contribute to rising rates of inflammatory diseases and diabetes,” she said in a conversation with Fox News Digital.

Muhlstein added that edamame (made from young soybeans), organic tofu and tempeh (both soy-based foods), and unsweetened soy milk are all “great sources of plant-based protein in an overall healthy diet.”

“I wouldn’t consider any of these foods ultra-processed at all, given that they are all nutrient-dense with protein, fiber, calcium and phytonutrients,” she said.

While this latest research focused on soy milk’s heart-benefiting features, Muhlstein noted that soy has been shown in several studies to be “cancer-preventative.”

Mark Messina, PhD, SNI’s global director of nutrition science and research, noted that plant-based milks have become increasingly popular in recent years, which makes it important to “fully understand their health effects, since they vary in composition.”

“The current comprehensive analysis shows that soy milk, regardless of whether it contains added sugar, has advantages for cardiometabolic health,” he wrote in a statement sent to Fox News Digital.

“These findings are aligned with the Dietary Guidelines for Americans, which state that soy milk is the only plant milk that can be an appropriate substitute for cow’s milk,” he added.

The total sugar content of most soy milks is about 60% less than cow’s milk, according to SNI. (iStock)

Fortified soy milk includes levels of protein, calcium and vitamin D that are comparable to cow’s milk, and it is lower in saturated fat, SNI wrote.

The total sugar content of most soy milks is about 60% less than cow’s milk, according to the institute.

Erlich agreed that soy milk is the “only nutritionally suitable alternative to cow’s milk” that can provide “high-quality protein similar to animal protein.” 

A cup of soy milk contains 7 to 8 grams of soy protein, which is comparable to the amount of protein in cow’s milk, she noted.

The Food and Drug Administration (FDA) has stated that 25 grams or more of soy protein per day has been associated with reduced risk of coronary heart disease, when consumed as part of a diet low in saturated fat and cholesterol.

Heart disease threat projected to climb sharply for key demographic

NEWYou can now listen to Fox News articles!

A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.

The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.

More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.

The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.

As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Not all trends were negative, as unhealthy cholesterol prevalence is expected to drop to about 22% from more than 42% today, the report stated.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”

“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.

NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW

“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”

The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.

The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.

“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”

Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.

The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”

“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”

“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)

The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.

“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”

Common vision issue linked to type of lighting used in Americans’ homes

Common vision issue linked to type of lighting used in Americans’ homes

NEWYou can now listen to Fox News articles!

Nearsightedness (myopia) is skyrocketing globally, with nearly half of the world’s population expected to be myopic by 2050, according to the World Health Organization.

Heavy use of smartphones and other devices is associated with an 80% higher risk of myopia when combined with excessive computer use, but a new study suggests that dim indoor lighting could also be a factor.

For years, scientists have been puzzled by the different ways myopia is triggered. In lab settings, it can be induced by blurring vision or using different lenses. Conversely, it can be slowed by something as simple as spending time outdoors, research suggests.

Nearsightedness occurs when the eyeball grows too long from front to back, according to the American Optometric Association (AOA). This physical elongation causes light to focus in front of the retina rather than directly on it, making distant objects appear blurry.

Researchers at the State University of New York (SUNY) College of Optometry identified a potential specific trigger for this growth. When someone looks at a phone or a book up close, the pupil naturally constricts.

COMMON VISION ISSUE COULD LEAD TO MISSED CANCER WARNING, STUDY FINDS

“In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study, said in a press release.

“When people focus on close objects indoors, such as phones, tablets or books, the pupil can also constrict — not because of brightness, but to sharpen the image,” she went on. “In dim lighting, this combination may significantly reduce retinal illumination.”

High-intensity natural light prevents myopia because it provides enough retinal stimulation to override the “stop growing” signal, even when pupils are constricted. (iStock)

The hypothesis suggests that when the retina is deprived of light during extended close-up work, it sends a signal for the eye to grow.

In a dim environment, the narrowed pupil allows so little light through that the retinal activity isn’t strong enough to signal the eye to stop growing, the researchers found.

In contrast, being outdoors provides light levels much brighter than indoors. This ensures that even when the pupil narrows to focus on a nearby object, the retina still receives a strong signal, maintaining healthy eye development.

The team noted some limitations of the study, including the small subject group and the inability to directly measure internal lens changes, as the bright backgrounds used to mimic the outdoors made pupils too small for standard equipment.

Researchers believe that increasing indoor brightness during close-up work could be a simple, testable way to slow the global nearsightedness epidemic. (iStock)

“This is not a final answer,” Jose-Manuel Alonso, MD, PhD, SUNY distinguished professor and senior author of the study, said in the release.

“But the study offers a testable hypothesis that reframes how visual habits, lighting and eye focusing interact.”
