There are more than 54 million people in the US aged 65 or older with this figure expected to continue to increase over the next 20 years. Similar trends are seen across the globe with 11% of the population classified as elderly in Israel in 2015- a number that has an expected 77% increase over the next 15 years. In Israel the percentage of the elderly population living in nursing homes stands at 4.5%, assisted living facilities 2%, leaving the majority of this population still living within the community. The presence of food allergies within the elderly community is currently estimated between 5%-10% but the real figure is said to be much higher due to the population being underdiagnosed with a recent study showing numbers at high as 20% in those aged 60 to 79 years.
----------Food allergies can be particularly dangerous for seniors due to their weakened immune systems----------
These numbers pose a significant challenge to the ever-growing prevalence of food allergies in the elderly population, a greatly under-researched sector. Excuses given for the lack of research includes; subjects are too tired to properly use in the study, their lack of interest in science, and reliability among others. However, those are just that- excuses, and with food allergies on a drastic rise and the lifespan increase over the last 20 years- it is imperative that researchers place a focus on this sector of the food allergy community as quickly as possible. Further research into food allergies of the senior population is particularly important as any allergy that can affect a whole food group needs to be closely monitored to avoid a vitamin or mineral deficiency- increasing the risks of malnutrition, an issue particularly prominent in this population.

Managing a food allergy as an senior presents unique challenges to an already more complicated period in ones life. The situation is especially delicate when dealing with food allergies as a couple- when one spouse has a sudden onset of food allergies, when placing an elderly person in a care facility or when making decisions regarding a person with dementia who has a food allergies.
