Ackee fruit, a semi-poisonous berry found in Jamaica and nearby regions, tastes a bit like cheese and is not at all nutritionally similar to fruits found on the Bright Line Eating food plan. For example, a 6 oz. serving of ackee fruit has 255 calories (for comparison, a 6 oz. serving of blueberries has 98 calories) and over 25 grams of fat (whereas a 6 oz. serving of blueberries has 0.6 grams of fat). If you want to eat ackee fruit, weigh out 3 oz. and count it as a fat serving.
