Advice about how to eat for good health sometimes changes. To you, it may seem like scientists can't make up their minds.

What foods have you thrown out recently? Maybe some slimy salad greens, moldy bread or a bit of leftover spaghetti? If you can't think of any food you've tossed lately, you're doing better than most of us. Each year, the average family of four throws out over 1,000 pounds of food at a cost of $1,500.

The vast majority of us fall short of meeting vitaminE recommendations. But, that doesn't mean we have a vitaminE deficiency. Outright vitaminE deficiency is uncommon.

High-oleic sunflower oil is a type of plant oil made from sunflower seeds that have been conventionally bred to be high in oleic acid (a monounsaturated fatty acid) and low in linoleic acid (a polyunsaturated fatty acid). There is a minimum of 80% oleic acid in high-oleic sunflower oil. In comparison, traditional sunflower oil has less oleic acid (around 20%) and more linoleic acid. Both high-oleic and traditional sunflower oils are low in saturated fatty acids. Either type of sunflower oil is a good choice from a cardiovascular standpoint, but the traditional oil is less commonly sold in stores or used by the food industry.
