Chia Pudding (chia seeds soaked in milk forming gel-like texture) became health food trend (2015-2019) touted for omega-3s, fiber, and Instagram-worthy layers. Simple to make, actually nutritious, and endlessly customizable with fruits/toppings, it represented rare health trend backed by actual nutrition science. Some found texture off-putting (“frog eggs”), but it maintained steady popularity.
