Updated guidelines say adults don't need routine testing of vitamin D levels. However, they should aim for daily vitamin D intake of 600 international units (IU) until age 70, and 800 IU after that either through vitamin D–fortified foods or a supplement of up to 1,000 IU.

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

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.

Eating a plant-based diet that includes a variety of fruits and vegetables has been shown to help lower high blood pressure. A 2024 study has found that these foods may also protect against worsening of chronic kidney disease in people with high blood pressure.

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.

Osteopenia is the precursor stage to osteoporosis (weak, thin bones that break easily). Ways to treat osteopenia include taking medications that slow bone loss and reduce fracture risk, exercising, eating protein- and calcium-rich foods, taking a calcium supplement to make up for a lack of dietary calcium, taking a vitamin D₃ supplement to help absorb calcium, and avoiding excessive alcohol intake. Vibration therapy (standing on a small vibrating platform) is not yet proven to be effective.

Older adults who consume ultra-processed foods as a substantial part of their diet have a higher risk of early death than those who eat less of these foods.
