26 Jul 2019 --- Around 80 percent of Americans’ calorie consumption comes from store-bought food and beverages, which are mostly ultra-processed and generally unhealthy, according to a study from Northwestern Medicine, US. This means Americans are overexposed to products high in energy, saturated fat, sugar and salt, increasing their risk of chronic diseases such as obesity and cardiovascular disease. Researchers are now calling for food manufacturers to reformulate unhealthy products and for the government to take action.
