The first general criticism of the use of the term "superfood" is that, while the food itself might be healthful, the processing might not be. For example, green tea has several antioxidants. But green tea sold in the United States is generally cut with inferior teas and brewed with copious amounts of sugar. The Japanese and Chinese generally do not drink green tea with sugar. Many kinds of super-juices — acai berry, noni fruit, pomegranate — can be high in added sugar. organifi green juice reviews organifi protein organifi complete protein reviews organifi yoga burn reviews Similarly, many whole grains are processed in a way to be more palatable and less healthful. For example, instant whole-grain oats are as unhealthy as overly processed white bread in that they quickly spike sugar levels in the bloodstream once consumed, promoting insulin-resistance, obesity and diabetes, according to research by David Ludwig at Harvard University.
