Yearly, as sure seasonal intervals strategy, some “new and unique” meals develop into trendy. That is the case of quinoa, goji berries, coconut oil, spirulina, chia seeds, kale … These promise “an infinite listing of vitamins”, a “lengthy life” and “iron well being ”.
What will we imply by the time period “superfood”?
Let’s do an web seek for the phrase “superfood.” In just a few seconds we’ll discover greater than 4,000,000 matches.
