09 Dec 2019 --- According to the World Health Organization (WHO), by 2050 the global population of people over the age of 60 is forecasted to more than double to two billion. The frailty of this population partially hinges on nutrition and the role that macronutrients and vitamins play in the aging process. Suppliers at Fi Europe 2019, held in Paris, France, last week, were clearly taking note of this. Companies spotlighted their ingredient’s efficacy for seniors, as well as younger demographics engaging with preventative aging. NutritionInsight spoke with a number of suppliers on the floor on key aging ingredients, from omega 3 to folic acid and MGCPQQ.
