Enter blue light-blocking glasses, also called blue light glasses or blue light-filtering glasses.

A plant-forward diet is your best bet for healthy aging, according to a recent high-profile study, but it doesn’t mean becoming a vegetarian or vegan. Plant-forward diets encompass a wide range of diets that include some meat — including pescatarian, flexitarian, and the popular Mediterranean diet — all of which are rich in fruits, vegetables, nuts, seeds, whole grains, legumes and beans. This eating pattern doesn’t mean going fully plant-based; it simply means deprioritizing meat as the star of your plate. In this episode, we delve into plant-forward eating, exploring its health benefits and how to get started with this approach.
