potatoes

If the fear mongers about GMO foods don't get their way, new strains of potatoes genetically engineered to contain beta-carotene and alpha-tocopherol (vitamins A and E) could potentially reduce vitamin deficiencies in areas of the developing world, where potatoes are staple foods.
Researchers from Boston report that eating white potatoes, even as potato chips, are linked to developing high blood pressure (the increased risk is small). But we question whether anyone should change their diets because of studies like this that show only associations, not causation.
