Aging is normal and natural, but how we age can vary from person to person. While genetics do play an important role in how we age, the foods we eat and the habits we form each day can have a major impact on how well our bodies function over time. From maintaining energy levels to supporting muscle strength and reducing inflammation, the foods we eat and our lifestyle choices are powerful tools in aging.

Dr. Paul Saladino, an expert in the field of nutrition and supplements, explains in this video the impact that diet has in aging. He even highlights just two specific foods and one key lifestyle change that can make a big difference in how we age. These strategies aren’t about trendy diets or extreme routines, either. They’re simple changes you can make that support cellular health, reduce inflammation, and help you age more gently. Here are two foods and one lifestyle change he recommends.

1. Red Meat

Sometimes we think of red meat as bad for our health, but as Dr. Saladino explains, that isn't always the case. Red meat, when consumed in moderation, can be a powerful ally in healthy aging. It’s rich in high-quality protein, which is important for maintaining muscle mass and helping us stay mobile as we get older. It also provides important nutrients like iron, zinc, and B vitamins, including B12, which supports energy production and brain function. Contrary to some outdated views, lean cuts of red meat can be part of a nutrient-dense, anti-inflammatory diet when paired with healthy lifestyle choices.

2. Liver

Liver is one of the most nutrient-dense foods available, making it an excellent anti-aging food. It’s packed with vitamin A, which is vital for skin health, immune function, and cellular repair. It is also rich in B vitamins, iron, copper, and CoQ10. Moderate consumption of liver can help protect against the cellular damage that contributes to age-related diseases.

3. Sunlight

Obviously it's not a food, but safe exposure to sunlight is a simple, effective lifestyle habit for promoting healthy aging. Sunlight helps our bodies produce vitamin D, a vitamin that plays a major role in bone health, immune regulation, and mood stabilization. Vitamin D deficiencies are linked to fatigue, weakened immunity, and even cognitive decline. Try to get outside every day (and don't forget your sunscreen).
