Lutein or zeaxanthin in Yellow Corn and Vision
I normally don't eat corn, but one day when I had two ears of corn, I noticed several hours later that my vision had become sharper. This lasted half a day and then returned to normal. A day later I ate 2 ears of corn for a second time, and a few hours later my vision got better again. I think the lutein or xeazanthin in the corn helped my vision but I am not sure.

Characterization of anthocyanin-rich waste from purple corncobs (Zea mays) and its application to color milk.

Pigment production from anthocyanin-rich purple corncobs generates a deeply colored waste precipitate. Our objectives were to characterize this anthocyanin-rich waste and to find a suitable application in a food matrix.

Dietary cyanidin 3-O-beta-D-glucoside-rich purple corn color prevents obesity and ameliorates hyperglycemia in mice.

Anthocyanins, which are used as a food coloring, are widely distributed in human diets, suggesting that we ingest large amounts of anthocyanins from plant-based foods. Mice were fed control, cyanidin 3-glucoside-rich purple corn color, high fat (HF) or HF + purple corn color diet for 12 wk. Dietary purple corn color significantly suppressed the HF diet-induced increase in body weight gain, and white and brown adipose tissue weights. Feeding the HF diet markedly induced hypertrophy of the adipocytes in the epididymal white adipose tissue compared with the control group. In contrast, the induction did not occur in the HF + purple corn color group.  Our findings provide a biochemical and nutritional basis for the use of purple corn color or anthocyanins as a functional food factor that may have benefits for the prevention of obesity and diabetes.
