Easy Berry Parfait with Greek Yogurt

Research tracking American dietary patterns over the past fifty years consistently documents both significant improvements and significant concerns. The increase in variety — in the diversity of fruits, vegetables, and whole grains available and consumed — represents genuine nutritional progress. The concurrent increase in ultra-processed food consumption — foods engineered for palatability, shelf stability, and convenience rather than nutritional completeness — represents one of the most significant public health challenges of the era. The most consistent finding across this research is that the greatest determinant of dietary quality is the degree to which food is prepared from whole ingredients rather than purchased in processed form — making cooking from scratch one of the most significant health behaviors available, regardless of the specific cuisine or ingredients involved.
