The facts on fiber

Adults should consume 14 grams of fiber for every 1,000 calories consumed. However, most individuals eat less than half that amount daily. People can increase their daily fiber intake by introducing more high-fiber foods, such as fruits, vegetables, whole grains, nuts, and seeds into their regular meals. Those who have trouble consuming these foods may benefit from taking an over-the-counter fiber supplement.

Eating more plant-based fat may help your heart

Over a 24-year span, people whose diets favored plant-based fat lived longer than people who ate more animal-based fat, according to a 2024 study. The same distinction appeared specifically for deaths from heart disease.

Using a salt substitute can lower risk of developing high blood pressure

A 2024 study suggests that swapping table salt for a salt substitute can markedly lower the risk of developing high blood pressure.

Short bursts of evening activity fuel better sleep

A 2024 study suggests that short bursts of light activity before bedtime may improve sleep.

Counting steps or exercise minutes both work to promote health

A 2024 study suggests that women who engage in the most physical activity-regardless of how it's measured-have significantly lower risks of developing cardiovascular disease or dying early.

Is it time for a knee replacement?

Annually, about 790,000 Americans (about 60% women) undergo knee replacement surgery. Women are more likely to have arthritis, the main culprit leading to most knee replacements. Before surgery becomes an option, people first need to try conservative treatments such as pain relievers, injectable medications, and physical therapy. Signs a knee replacement may be necessary include pain that hinders people from doing basic activities, unstable walking, and needing multiple medications to function.

Are cracked cuticles harmful?

Cuticles hinder germs from entering the nail bed. Dry, cracked, or damaged cuticles may become infected, leading to a red, swollen, painful area around the nail. Mild nail infections can be treated at home, but people should see their doctor if the infection doesn't resolve.

Is charcoal toothpaste safe for my teeth?

Charcoal toothpastes, marketed as tooth whiteners, contain activated charcoal, an abrasive substance that can help remove surface stains. While safe in small doses, charcoal toothpaste shouldn't be used daily, since it may damage tooth enamel.

Nutritional power couples

Certain food pairings work synergistically, enabling the body to absorb nutrients more efficiently than if either food were eaten alone. Other combinations keep people full longer. Examples of synergistic combinations include beans and brown rice, spinach and citrus, cereal and milk, tomatoes and olive oil, apples and peanut butter, and turmeric and black pepper. But people absorb nutrients differently, meaning there's no guarantee someone will extract as many nutrients from a certain combination of foods as another person does.

Low-dose aspirin now the preferred agent to help prevent blood clots after knee replacement

A 2024 study found that low-dose aspirin therapy was more effective than taking anticoagulants for reducing the risk of blood clots following a total knee replacement surgery. Aspirin therapy also caused fewer bleeding complications.
