What we eat earlier in life has a profound effect on long-term health and aging. Many studies confirm that eating a healthy diet and exercising regularly is essential to long-term health.
Multiple studies have found that proper nourishment can increase life expectancy. The biggest gains come from eating plenty of nuts and legumes, whole grains, fruits, vegetables. Also, indulging in less processed meat, red meat, sugar and refined carbohydrates has a significant positive effect. And, a large study showed that artificially sweetened soft drinks are associated with deaths from circulatory diseases.1
A 2023 study showed an increase for 40 year-old males and females in longevity of 10.8 and 10.4 years respectively, with the largest gains resulting from consuming more whole grains, nuts and fruits and less sugar-sweetened beverages and processed meats.2
A Harvard study3 showed that five lifestyle factors appear to be the most important for a longer, healthier life. They are: 1) eating a healthy diet, 2) exercising regularly, 3) maintaining a proper diet weight, 4) not smoking, 5) drinking alcohol only in moderation.
The study determined that men practicing four or five of these healthy habits at age 50 lived approximately 31 additional years free of chronic disease. In contrast, men who did not follow the recommendations only got 24 years, a 6-year difference on average. Men who were currently heavy smokers, and men and women with obesity, had the lowest life expectancy free of disease.
Women at age 50 who incorporated four or five of the healthy habits got about 34 more years free of cardiovascular disease, diabetes, and cancer. Women who did not practice the healthy habits only got 24 years disease-free, a difference of 10 years.
Other important lifestyle considerations related to long term health included: healthy social engagements, brain stimulation exercises or interests, good sleep habits, having a purpose or meaning in life, and intermittent fasting.
Sensory Changes With Aging Affect How We Eat
Seniors gradually develop a reduced sense of taste and smell. The sensation of crunching food in the mouth can diminish. Up to 60% of adults 70 years and older may lose their sense of taste.4
Other factors that may reduce your food satisfaction include:
- prescription drugs that reduce taste sensitivity and promote dry mouth or lack of saliva
- deficiencies in micronutrients such as zinc that reduce taste
- poor dental health with tooth loss or dentures, leading to chewing problems. 5
You can improve food satisfaction by adding tasty herbs and spices when cooking. Savory ingredients such as mushrooms, tomatoes, some cheeses, and nutritional yeast boost richness and flavor. A variety of textures, aromas, and colors in a meal may stimulate an increased desire to eat. 6
