In various studies from 2013 to 2023, researchers like those from the University of Manchester and NBER analyzed data from thousands of retirees in cohort and longitudinal setups. They tracked health changes post-retirement, focusing on cognitive, physical, and mental aspects, adjusting for age, job type, and voluntary status.

In 2025, researchers Shuai Ma, Yu Miao, and Xinxin Wu from Heilongjiang University of Chinese Medicine analyzed data from NHANES 2007–2018 on 27,487 U.S. adults. They looked at intake of fermented dairy like yogurt, cheese, and buttermilk, using surveys and health records to link it to stroke history, adjusting for age, smoking, and other factors.

This statement by Dr. Gabrielle Lyon isn’t just catchy—it’s scientifically sound. A 2024 Scientific Reports study analyzing nearly 11,000 adults found that a high lean mass to visceral fat ratio was tied to up to 88% lower risk of type 2 diabetes and significantly fewer cases of high blood pressure and abnormal cholesterol levels.

A 2018 editorial in Open Heart by DiNicolantonio & O’Keefe highlights that the typical Western diet—with high omega-6 and low omega-3 fats—promotes inflammation linked to heart disease and chronic illness. They stress the importance of keeping omega‑6/omega‑3 ratios low to reduce inflammatory signaling like platelet aggregation and oxidative stress.

A 2025 EMJ Neurology report highlights groundbreaking lab findings that the popular artificial sweetener erythritol—often found in sugar-free drinks—can impair brain blood vessel health. In simpler terms, this means erythritol could reduce blood flow to the brain and increase stroke risk.

A 2025 study analyzing 85 previous studies found that people who stay consistently active have a 30–40% lower risk of early death—especially from heart disease. Even those who start exercising later in life still see a 20–25% drop in mortality risk, showing it’s never too late to change your future.

Globally, added sugar now makes up around 10% of total calories consumed, ranking just behind grains and produce. But while those provide some nourishment, sugar contributes little and harms much. A 2023 Annual Review study warns that sugar—not fat—is driving the chronic disease epidemic. And sugar-sweetened beverages (SSBs) are the worst offenders.

A 2025 analysis within the Malmö Preventive Project (1,792 adults, ~13 years follow-up) found that a higher waist‑to‑height ratio (WtHR)—not BMI—was strongly linked to incident heart failure.

A 2025 MRI study from the University of Toronto found that long-term exposure to even low levels of air pollution causes hidden heart damage, specifically increasing myocardial fibrosis—a form of scarring linked to future cardiovascular disease.

Researchers at the University of the Basque Country (2025) have discovered that saliva contains hundreds of DNA methylation markers linked to major diseases—including cancer, coronary artery disease, type 2 diabetes, and Parkinson’s.

A 2025 analysis in Frontiers in Nutrition by He, Wang & Li used data from 12,432 U.S. adults to link specific pesticide chemicals—including the herbicide 2,4-D, organophosphates, and glyphosate—to poorer overall cardiovascular health.

A 2025 study from the University of Oregon’s Bowerman Sports Science Center found that soaking in a hot tub raised core temperature the most, triggering stronger cardiovascular and immune responses—like increased heart output, improved blood flow, lower blood pressure, and boosted white blood cells—compared to saunas.

A 2016 systematic review published in the journal Heart found that loneliness and social isolation raise your risk of heart attack by 29% and stroke by 32%—numbers comparable to the effects of light smoking or obesity. Researchers analyzed data from 23 studies involving over 181,000 adults, tracking heart attacks, strokes, angina, and cardiovascular deaths.

A 2025 study led by Columbia University found that people who spent more time sitting after a heart attack or chest pain episode had more than 2.5 times higher risk of dying or having another heart event within a year. But there’s good news: swapping just 30 minutes of sitting for light activity—like walking or tidying up—cut the risk by 50%, and moderate activity cut it by 61%.

A 2024 study from Tufts University published in The Journal of Nutrition found that drinking 1–3 cups of black coffee per day was linked to a 14–17% lower risk of death from any cause, including cardiovascular disease. But when that coffee is loaded with sugar or saturated fat, the benefit fades fast.

A 2023 summary from Georgia State University and the Society of Behavioral Medicine shows that micro-workouts—short bursts of physical activity lasting from 30 seconds to 10 minutes—can have major benefits for heart health, blood sugar control, mental well-being, and overall endurance.

In a 2025 study, researchers examined U.S. dietary data from 2003–2018 to uncover trends in extreme sodium consumption—the top 5% of daily salt intake. They found these extreme levels climbing higher over time, with a growing group consuming far beyond the recommended upper limit of 2,300 mg/day.

A 2025 study backed by the National Institute for Health and Care Research found that a new at-home foot scanner from Heartfelt Technologies could detect fluid build-up—an early sign of heart failure—an average of 13 days before a patient needed hospital care. It accurately predicted 5 of 6 hospitalizations.

A 2025 systematic review in Nutrients analyzed clinical and experimental studies, concluding that EVOO consumption is linked to improved cardiovascular health. Its rich content of monounsaturated fats and polyphenols contributes to lowering LDL cholesterol, reducing blood pressure, and enhancing endothelial function.

A 2025 study from UC San Francisco, published in JAMA Cardiology, found that chronic cannabis use—whether smoked or consumed as edibles—is linked to significantly reduced blood vessel function, comparable to the effects seen in tobacco smokers.
