Fatty fish, such as salmon, mackerel, and sardines, are good dietary sources of CoQ10 and also provide heart-healthy omega-3s.
Organ meats like beef liver and heart contain the highest natural concentrations of CoQ10 and can be included in a balanced diet.
Supplements are available for those with low dietary intake or specific medical needs, but should be used under medical guidance.

The NIH CoQ10 Fact Sheet notes CoQ10’s potential to support heart health and energy, especially in seniors or those taking statins. Including CoQ10-rich foods, and considering supplements when appropriate, may help maintain vitality and cardiovascular well-being with age.

38. Collagen

Collagen is the most abundant protein in the body, providing structural support for skin, joints, and bones. As we age, natural collagen production declines, leading to signs of aging such as wrinkles, joint discomfort, and reduced bone density. Supporting collagen intake can help seniors maintain skin elasticity, joint flexibility, and strong connective tissues, all of which are vital for mobility and quality of life.

Bone broth made from simmering animal bones and connective tissue is a traditional, nutrient-rich source of collagen peptides.
Chicken skin and fish skin contain natural collagen and can be enjoyed in moderation as part of a balanced diet.
Collagen supplements in powder or capsule form are widely available and may help support skin, joint, and bone health, especially for those with limited dietary intake.

The Mayo Clinic notes that while research on collagen supplements is ongoing, a balanced diet with collagen-rich foods can support connective tissue health. Including collagen sources regularly may help seniors maintain mobility, youthful skin, and overall resilience as they age.

39. Antioxidants

Antioxidants are compounds that protect the body from oxidative stress and cellular damage caused by free radicals. Over time, oxidative stress can contribute to aging and increase the risk for chronic diseases such as heart disease, cancer, and cognitive decline. For seniors, a diet rich in antioxidants is essential for defending against these age-related challenges and promoting overall wellness.

Mixed berries—including blueberries, raspberries, and blackberries—are rich in a variety of antioxidants, such as vitamin C and flavonoids.
Nuts like walnuts and pecans provide both vitamin E and plant-based antioxidants, supporting heart and brain health.
Dark leafy greens such as spinach, kale, and Swiss chard offer a potent mix of antioxidants along with important vitamins and minerals.

The NIH Antioxidants Fact Sheet highlights the broad benefits of eating a variety of antioxidant-rich foods rather than relying on supplements. By enjoying colorful fruits, vegetables, and nuts, seniors can help combat oxidative stress and support vibrant health at every stage of aging.

40. Phytosterols

Phytosterols are plant compounds that play a significant role in managing cholesterol levels, an important consideration for heart health as we age. These naturally occurring substances are structurally similar to cholesterol and compete for absorption in the digestive system, ultimately helping to lower total and LDL (“bad”) cholesterol. Seniors can benefit from including phytosterol-rich foods in their diet to support cardiovascular wellness and reduce the risk of heart disease.

Nuts such as pistachios, almonds, and walnuts provide a healthy dose of phytosterols, fiber, and beneficial fats.
Seeds, including sunflower and sesame seeds, are easy to sprinkle on salads, yogurts, or cereals for an extra phytosterol boost.
Vegetable oils like canola, soybean, and corn oil, as well as specially fortified foods (such as margarines or orange juice), are additional sources.

The American Heart Association recommends incorporating phytosterols as part of a heart-healthy eating plan. By making simple swaps and adding more nuts and seeds, seniors can naturally support healthy cholesterol and cardiovascular health.

Conclusion

A varied, nutrient-rich diet is one of the most powerful tools for healthy aging. By including a colorful array of whole foods—fruits, vegetables, lean proteins, whole grains, dairy, nuts, and seeds—seniors can meet most of their nutritional needs naturally. Simple swaps and small daily changes—like adding leafy greens, enjoying a handful of nuts, or choosing fortified foods—can make a significant difference. For tailored advice, consider consulting a registered dietitian or healthcare provider, especially when managing chronic conditions or medications. Prioritizing nutrition not only supports longevity but also helps maintain independence, energy, and a vibrant quality of life.
