The USDA updates its dietary recommendations every five years. The 2015-2020 Dietary Guidelines for Americans reviewed current research and now give a green light to limited amounts of lean red meat and poultry, whole eggs, shellfish, and coffee.
What's downgraded is added sugar, down from 15 percent of daily calories a day to 10 percent -about 10 or 12 teaspoons (about what's in a can of soda) . Salt is limited to no more than 2,300 milligrams per day – the equivalent of one teaspoon.
What's out completely are refined grains, processed meats, and eating more than 10% of daily calories from saturated fat.
