“Let food be thy medicine” is a quote attributed to Hippocrates, the ancient scholar considered to be the father of modern medicine.
The saying relates to the notion that what people put in their bodies can heal and/or prevent certain conditions.
For seniors with medicine cabinets full of over-the-counter and prescription medications, the idea of relying predominantly on food to promote optimal health may be tempting, and various foods can be particularly useful to the 50-and-over demographic.
According to the World Health Organization (WHO), poor diet is a major contributor to many of the diseases that affect older people. Poor diet has been connected to the development of diabetes, and degenerative diseases such as osteoporosis also may be linked to the foods ones eat.
The National Council for Aging Care says micronutrient deficiency is often a problem among the aging due to factors like lack of variety in diet and reduced food intake. Eating a variety of foods can provide all of the nutrients people need to stay healthy as they get older. Certain foods may be particularly helpful.
• Brain-friendly foods: Foods such as avocado, leafy vegetables, sunflower seeds, blueberries, and salmon are good sources of vitamin E, antioxidants, omega-3 fatty acids, and other nutrients that may help ward off dementias like Alzheimer’s disease, according to Sonas Home Health Care.
• Anti-inflammatory foods: Foods rich in omega-3 fatty acids may help prevent inflammation that can cause cancer and rheumatoid arthritis. Aging.com says foods that are high in omega-3 fatty acids, like salmon, should be consumed at least twice per week.
• Fruits and vegetables: Fresh, canned or frozen produce tend to be high in micronutrients, including a variety of important vitamins that are essential for all components of health. The Academy of Nutrition and Dietetics advises eating dark green vegetables, such as leafy greens or broccoli, and orange vegetables, such as carrots and sweet potatoes.
• Energy-boosters: Choose whole grains that can provide sustained energy by way of healthy carbohydrates over processed grains.
• Bone-friendly foods: Calcium-rich foods, such as milk, yogurt and cheese, can prevent calcium from being leached from the bones, which contributes to conditions like osteoporosis.
• Digestive system-friendly foods: The digestive system slows down as the body ages, as the walls of the gastrointestinal tract thicken and digestive contractions that push waste along may slow down and become fewer. Foods rich in fiber can promote proper digestion by moving food through the digestive tract more easily. High-fiber foods also may help naturally reduce blood cholesterol levels.
• High-iron foods: Without enough iron in the body, a person may feel tired and lethargic from a reduced production of hemoglobin, which carries oxygen in the blood from the lungs to the rest of the body. A lack of oxygen in body tissues from anemia can be serious, says the National Council for Aging Care. Tofu, spinach, lentils, pumpkin seeds, and fortified breads and cereals are high in iron.
Smart food choices can help everyone live long and healthy lives.
