Dominicans may not be malnourished but I do not think anyone could say that the average diet of the less well off Dominican is healthy. Very high in oil and salt and sugar. Main staple is rice or plantain or root vegetables such as yuca. Low in fresh green vegetables and salad. Yes there is some meat and occasionally fish and eggs. I would say low in vitamins too. The good point is nearly all if not all of the food is organic, no fast food, no pre packed frozen stuff, and lots of fresh fruit straight from the tree.

Really, I've eaten at many a Dominican house, and watched Dominicans shopping for food. The Fruit and vegetable markets in Jarabacoa sell peppers, tomatoes, onions, carrots, cucumbers, lettuce, cabbage, potatoes, and then there's the fruit. It's true that green bananas, yucca, rice, beans, and chicken are the staples. The truly poor don't have the money for sugar, or much salt. As an aside Goiter is a serious problem in the DR, but less now that iodized salt is available. Rice and beans is usually cooked with Cilantro, onions, garlic at least in my mother-in-laws kitchen. I have eaten in campo kitchens where the people eat only what they grow, and these people live to be very old.
