The richest sources of free lutein in the typical US diet are dark green leafy vegetables, with the highest concentration found in kale follwed by spinach.
The average daily lutein intake is low, averaging between 1-2 mg/day. Currently there is no recommended intake for lutein. However, if you were to eat according to the recommendation of the Dietary Guidelines for Americans 2005 ( 9 servings of fruits and vegetables every day) you would consume between 4 and 8 mg of lutein a day (7). Epidemiological evidence, animal models, and clinical data have indicated levels of 6-10 mg a day may be necessary to realize the health benefits associated with lutein consumption. By continuing to increase our intake of lutein, we begin to ensure the optimal health of our eyes.
