Nutrition and Healthy Aging

Aging might be inevitable, but HOW we age is largely up to us. One of the ways we can influence how we age is through what we put into our bodies. Nutrition plays a pivotal role in healthy aging, impacting everything from cognitive function to cardiovascular health and our immune response. While genetics plays a role in aging, it’s not something that we can do much about.  Our lifestyle choices however, including our dietary habits, are absolutely within our control.

Aging can be defined as a gradual decline in the physiological functions required for survival.  As we age, we experience an increase in inflammation and have a higher risk of developing chronic diseases such as cardiovascular disease, diabetes, and osteoporosis. A well-balanced diet can reduce these risks, improve longevity, and enhance your quality of life.  Here’s how.

Key Nutritional Strategies for Healthy Aging

1. Prioritize Protein to Preserve Skeletal Muscle - Sarcopenia, the age-related loss of muscle mass, begins in your 30’s and accelerates after 60.  It is estimated that we lose 3-5% of our muscle mass each decade after 30 and this can increase up to 10% as we enter our 50s and 60s.  Research suggests that protein intake beyond the Recommended Dietary Allowance (RDA) of 0.8 g/kg/day is necessary to preserve lean muscle mass and strength. The International Society of Sports Nutrition recommends an intake of 1.2–2.0 g/kg/day for aging adults to prevent sarcopenia.  Make sure to consult with a medical professional or registered dietitian before significantly increasing your protein intake as certain medical conditions may require special guidelines.

   
   

2. Healthy Fats for Brain and Heart Health - Omega-3 fatty acids, primarily found in fatty fish, walnuts, flaxseeds, and chia seeds, have been linked to cognitive preservation and cardiovascular health. A study published in Neurology (2021) found that higher blood levels of omega-3s were associated with a lower risk of dementia. Replacing saturated fats with monounsaturated and polyunsaturated fats, which are found in olive oil, avocados, and nuts, may help reduce inflammation and support heart health.

   
   

3. Quality Over Quantity When It Comes to Carbs – Refined (meaning heavily processed) carbohydrates and sugars contribute to inflammation and insulin resistance, increasing the risk of developing chronic diseases. Focus on complex carbohydrates such as whole grains, legumes, fruits, and vegetables, which provide essential fiber, vitamins, and antioxidants. Fiber intake is particularly important for digestive health, helping to prevent constipation and maintain a healthy gut microbiome with the American Heart Association recommending at least 25-30 grams of fiber daily for most adults.

   
   

Micronutrients and Their Role in Aging 

Several vitamins and minerals play a big role in aging, including (but not limited to) the following:

• Vitamin D and Calcium are essential for bone health and help reduce the risk of developing osteoporosis. The National Osteoporosis Foundation recommends older adults get 1,200 mg of calcium and 800–1,000 IU of vitamin D daily.

• Vitamin B12 absorption declines with age and since this vitamin is important for neurological function it’s one to keep an eye on.

• Magnesium supports muscle function, heart health, and bone density.

Other Often-Overlooked Factors

• Hydration - As we age, our sense of thirst diminishes, increasing the risk of dehydration. Chronic dehydration can contribute to cognitive decline, kidney dysfunction, and decreased skin elasticity.

• The Role of the Gut Microbiome - Emerging research highlights the importance our gut microbiome plays in our overall health. A diverse and balanced gut microbiota can reduce inflammation, enhance immunity, and improve mental health. One study found that gut microbiome diversity is associated with healthier aging and a longer lifespan.

• Mindful Eating and Lifestyle Integration – It isn’t just what we eat, but how we eat that matters. Mindful eating - paying attention to hunger and fullness cues, eating slowly, and savoring meals - can prevent overeating, support digestive health, and encourage better nutritional choices.

  
  

Aging well isn’t just about adding years to life, it’s also about the quality of life so that you can enjoy those extra years. By focusing on a well-balanced, nutrient-dense, anti-inflammatory diet, staying hydrated, and monitoring your micronutrient levels, you can turn getting older into an adventure.
