How do the anthocyanin levels compare to other fruits and vegetables?
This is a difficult question to answer because the amounts found in fruit depends on many factors, including variety, growing conditions, and extraction and measurement methods. As a rough guide, the total anthocyanin levels of fresh purple tomato fruit are about 1/10 or 1/20 of that found in blueberries, (in mg/gram fruit). Blueberries are one of the richest sources of anthocyanins. Americans consume an average of 12.5 mg anthocyanin per day (blueberries have 1-3 mg/gram fresh weight, purple tomatoes have 0.1-0.3 mg/gram FWfresh weight, so a person would have to eat about 10 purple cherry tomatoes for an ‘average’ anthocyanin serving). While other fruits have a higher concentration of anthocyanin, tomatoes are consumed on practically a daily basis in the U.S. Americans eat about 90 pounds per person per year of fresh and processed tomatoes, second only to potatoes in consumption of fruits and vegetables. In contrast, Americans ate less than 1 pound of fresh and frozen blueberries per
