The elderly in the future are different
Date: January 12, 2019
In the future, we will experience some very diverse nutritional needs from the elderly. Nevertheless, some nutritional needs can be generalised. Get the great research coverage made by INCluSilver.
As part of the INCluSilver project, which aims to improve the health of the “silver generation”,the University of Surrey has made a literature review on the research within the area of nutrition for the elderly. This research is thefirst step to be taken in the process of developing personalised nutrition for the silver population.
Here are the overall nutritional conclusions and recommendations for the elderly population:
- Vitamin C is good for people with a low level of vitamin C in their body.
- It has not been proven that a multivitamin supplement has an effect on health.
- Low vitamin E intake is related to poor health.
- The elderly should increase their folate intake only when their folate level is low and their B12 level high, not when their folate level is high.
- Studies confirm that calcium supplements have a positive effect on general health and other studies show that a higher calcium intake is associated with good bone health.
- Magnesium supplements improve health.
- Neither a high or low level of iron is healthy for the elderly.
- Studies show that protein supplements have a positive effect on muscle strength. Moreover, other studies show that protein intake leads to positive health benefits.
- Intake of omega-3 fatty acids has a positive effect on health.
- Intake of monounsaturated fatty acids leads to positive health benefits.
There were also other interesting results in relation to both micronutrients and macronutrients. However, since the results pointed in several directions, it was not possible to make convincing conclusions based on them.
Nutrition needs to be personalised
Moving away from generalised nutritional recommendations, it is important to remember that the mature adults are very heterogeneous. Therefore, the right diet and nutritional intake can be influenced by many factors such as activity level, seasonality requirements, geography, and ethnicity. Moreover, nutritional requirements are very different for people with long-term conditions, such as blood pressure, high cholesterol and type-2 diabetes, who have dietary requirements that are low in fat, salt, and refined sugar.
Overall, the conclusion is to consider generalised nutritional recommendations, while simultaneously getting better at integrating approaches to improve dietary intake of nutrients on an individualised level.
