Yes, Science says Eat Less Refined Carbs
Eating too many refined carbohydrates leads to weight gain and heart disease
The Origins of an Epidemic — the 1977 Dietary Guidelines and Food Pyramid
Prior to the 1970s, you ate what your mother cooked. The government, dieticians and doctors didn’t interfere with Mom. The 1970’s ushered in a huge change when the American government, for the first time in history told people what they should to eat to be healthy with its 1977 Dietary Guidelines for Americans. The verdict was to Eat Less Fat and Eat More Carbs.
Because these dietary guidelines had little firm scientific evidence, they get updated every 5 years, which usually ends up simply reflecting the national mood of the time. In 1977, white bread is good (low in fat) and in 2020 (the latest version of the Dietary Guidelines), it is bad (high glycemic index, highly refined, highly processed). In 1977, fatty foods like nuts, fatty fish and avocados are very bad (causes heart disease, don’t you know?). In 2020, nuts, fatty fish and avocados are very good (prevents heart disease, don’t you know?)
