Food insecurity rising among US older adults
Food insecurity-or limited access to nutritious foods because of a lack of financial resources-increased significantly among older US adults from 2007 to 2016 and the increase was more pronounced among individuals with lower income. The increase - from 5.5% to 12.4% - was reported in a recent study that drew from data from National Health and Nutrition Examination Surveys. The findings are important for all active-aging providers, but particularly those working in seniors centers and other community-based programs - and especially now, as COVID-19 is likely to have increased the number of low-income older adults.

Lifestyle improvements may curb cognitive decline
Many studies have shown that lifestyle changes can reduce the risk of dementia in the general population. "What this study adds is that with the right intervention, people experiencing cognitive decline may retain sufficient neuroplasticity for their brain to 'bounce back' from decline," said lead author Mitchell McMaster of The Australian National University. The findings are particularly important for management and staff at seniors centers and other community-based services.

Pesco-Mediterranean diet plus fasting optimal for heart
A Pesco-Mediterranean diet rich in plants, nuts, whole grains, extra-virgin olive oil, and fish and/or seafood is ideal for optimizing cardiovascular health, according to a cumulative review published in the Journal of the American College of Cardiology. Intermittent fasting is recommended as part of this diet. The study is important because it adds a new wrinkle - limiting daily intake of calories in a specific time window (usually between eight to 12 hours) each day - that may be of interest.

Certain food combinations linked to increased dementia risk
It's not just what foods you eat, but what foods you eat together that may be associated with the risk of dementia, according to a study published in the journal Neurology. ® "A number of studies have shown that eating a healthier diet - for example, a diet rich in green leafy vegetables, berries, nuts, whole grains and fish - may lower a person's risk of dementia. Many of those studies focused on quantity and frequency of foods," said study author Cécilia Samieri, PhD, of the University of Bordeaux in France.
