9 Key Nutrients Older Adults Are Likely Missing

Our dietary choices directly influence the aging process.

Nutrition has a profound effect on our bodies, affecting everything from our physical health to cognitive function. And as we age, paying attention to our dietary intake becomes not just a matter of maintaining an ideal weight, but a cornerstone of overall health and vitality.

Understanding Nutritional Needs

Older adults require a careful balance of nutrients to maintain optimum health. While certain dietary requirements decrease with age, others increase or remain the same. In many cases, the standard adult recommendations don’t fully apply to this age group. Older adults, and those caring for them, need to understand the essential nutrients often missing from their diets.

Vitamin B12

Vitamin B12 is critical for nerve function, brain health, and the production of red blood cells. It’s typically found in animal products, such as meats, fish, eggs, and dairy. However, older adults can have difficulty absorbing it from food due to a reduction in stomach acid. Thus, B12 supplementation or fortified foods may be necessary.


Calcium is needed for maintaining strong and healthy bones and teeth. As we age, our bodies become less efficient at absorbing this mineral, increasing the risk of osteoporosis. Dairy products, dark green leafy vegetables, and fortified foods are excellent sources of calcium.

Vitamin D

Vitamin D works hand-in-hand with calcium to support bone health, and it’s also crucial for immune function. Older adults, especially those with limited sun exposure or skin synthesis, may struggle to get enough. Fatty fish, fortified dairy products, and supplements can help meet vitamin D requirements.


A high-fiber diet helps to maintain good bowel health, lower cholesterol levels, and control blood sugar levels. Older adults often fall short of the daily recommended intake. Incorporating whole grains, fruits, vegetables, and legumes into the diet can help boost fiber intake.


Potassium is vital for heart health and proper cell function. While it’s abundant in fruits, vegetables, and dairy products, older adults often do not get enough. Increasing the consumption of potassium-rich foods, while simultaneously reducing sodium intake, can improve heart health.


Magnesium plays a vital role in a myriad of body processes, including blood sugar control, blood pressure regulation, and bone health. It’s found in many foods, including nuts, legumes, whole grains, and green leafy vegetables. Older adults often have lower magnesium levels, partly due to reduced dietary intake and partly due to reduced absorption.

Omega-3 Fatty Acids

Omega-3 fatty acids, primarily found in fatty fish, are essential for heart and brain health. Many older adults fail to consume the recommended two servings of fatty fish per week. Omega-3 supplements or incorporating flaxseeds, chia seeds, or walnuts into the diet can help.


Protein is for maintaining muscle mass, which tends to decrease with age. Older adults often consume less protein than they need, increasing the risk of frailty. Including lean meats, dairy, legumes, or plant-based proteins in every meal can help meet protein needs.


Iron deficiency isn’t as common in older adults as in younger people, but it’s still important to get enough. Iron is crucial for producing hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Good sources include lean meats, seafood, nuts, and iron-fortified cereals.

A Lifelong Commitment to Nutrition

Though it may seem daunting, incorporating these essential nutrients into your daily diet can be accomplished with just a little knowledge and planning. If necessary, consider consulting with a registered dietitian or nutritionist. They can help create a personalized eating plan that considers your age, lifestyle, preferences, and specific nutritional needs.

Ultimately, nutrition is a lifelong commitment, and never more so than as we age. The decisions we make about our diet today will significantly influence our health, vitality, and quality of life tomorrow.
