Foods that contain mainly saturated fat, such as beef tallow and butter, are less heart-healthy than those that contain mainly unsaturated fats, including olive oil and seed oils such as canola oil and soybean oil.

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.

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.

A 2026 research review and analysis suggested that consuming more soy products and other legumes was associated with a lower risk of developing high blood pressure.

Intravenous (IV) vitamin therapy delivers vitamins, minerals, and fluids directly into the bloodstream. It is marketed as a quick fix for fatigue, immune health, and hangovers. But scientific evidence does not back up those claims, and IV therapy also poses risks.

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.

People’s energy levels typically decrease later in life as a result of aging, illness, or other factors. Fortunately, a healthier lifestyle can boost energy. That involves eating a diet low in added sugars and processed foods, getting seven to nine hours of sleep each night, managing stress, getting lots of aerobic exercise, and strengthening the muscles. Using physical energy frugally is another useful strategy. For example, it helps to perform activities at a slow, steady pace instead of a fast pace; to break activities into small tasks instead of one large job; and to rest between tasks.

Most Americans fall short on their intake of potassium, a vital but overlooked nutrient. People can boost the level of potassium in their body by eating more plant foods, especially beans, potatoes, leafy greens, and fruit, and by cutting back on ultra-processed foods.
