Heart block is a slowdown or blockage of the electrical signals that travel from the upper to lower chambers of the heart. People with third-degree heart block (the most serious form) nearly always need a permanent pacemaker.
Early detection of colorectal cancer saves lives. Now there are more ways than ever to get screened (and fewer excuses not to). American Cancer Society screening guidelines now include colonoscopy, sigmoidoscopy, CT scanning, at-home stool testing, and blood testing.
A major Harvard study adds more evidence that a healthy diet may protect your brain. Older adults who ate the most ultra-processed foods were found to have substantially higher risks of dementia and cognitive decline, while those eating more minimally processed foods had lower risks.
The DASH diet is a flexible, science-backed eating plan proven to lower blood pressure, while also reducing risks of heart disease, diabetes, cancer, and cognitive decline. Emphasizing vegetables, fruits, whole grains, and low-fat dairy products, it’s a healthy way to eat that suits almost everyone.
For people managing a chronic illness or recovery, medically tailored meals—home-delivered and dietitian-planned—can help. Research shows they improve health outcomes, reduce hospitalizations, and save billions in health care costs. Programs range from full meal delivery to grocery boxes and produce vouchers.
Creating a calorie deficit—burning more than one consumes—is the foundation of sustainable weight loss. “Slow and steady” is best: experts recommend a 500-calorie daily deficit for gradual progress, combined with regular physical activity, especially strength training.
Aging is the single biggest risk factor for developing cancer. As people get older, DNA damage accumulates in cells, and chronic inflammation and imbalances in gut bacteria become more common. All of these factors may contribute to the age-related increase in cancer cases.
Many older adults feel they can’t keep up with the deluge of apps, texts, emails, patient portals, social media, and video calls that are now part of everyday life. Age-related brain changes can make digital overload more challenging, and too much screen time can affect physical and mental health.
A prediabetes diet is an eating plan that may help prevent prediabetes from turning into full-blown diabetes. Many different foods can fit into this style of eating, including fruits and vegetables, beans and legumes, lean proteins, whole grains, and healthy fats. While no foods are off-limits, prediabetes diets generally are low in sugary foods, refined carbohydrates, fast foods, fried foods, and alcohol.
Some prescription and over-the-counter drugs produce side effects that resemble problems tied to aging, such as memory lapses, balance issues, or fatigue. Older adults are more sensitive to medication side effects because their body composition and metabolism change.
