MY AVOS!
Avocados must be used when fully ripe. They do not ripen on the tree and are rarely found ripe in markets. Fresh avocados are almost always shipped in an unripe condition.
To test for ripeness by cradling an avocado gently in your hand. Ripe fruit will yield will be firm, yet will yield to gentle pressure. If pressing leaves a dent, the avocado is very ripe and suitable for mashing. They are best served at room temperature.
Avocado’s get a bad rap because of the “fat” content in it, when reality the fat that you get from it, happens to contain many beneficial attributes.
The avocado’s image first took on some polish with a 1996 study by researchers at the Instituto Mexicano del Seguro Social in Mexico (Archives of Medical Research, Winter 1996) that looked at the health benefits of daily avocado consumption. The 45 volunteers who ate avocados every day for a week experienced an average 17% drop in total blood cholesterol. Their cholesterol ratio also changed in a healthy way: Their levels of LDL (low-density lipoprotein, or “bad fat”) and triglycerides, both associated with heart disease, went down. Their HDL (high-density lipoprotein, or “good fat”) levels, which tend to lower the risk of heart disease, climbed.
Researchers have also discovered that avocados are rich in beta-sitosterol, a natural substance shown to significantly lower blood cholesterol levels. In a review article published in the December 1999 issue of the American Journal of Medicine, researchers pointed out that beta-sitosterol was shown to reduce cholesterol in 16 human studies.
Sneaking monounsaturated fats into your own daily diet may allow you to enjoy similar health benefits, says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer Research in Washington, D.C. Used creatively, she says, avocados can add variety — and good nutrition — to your diet. Instead of spreading butter or cream cheese on your bread or bagel, use some mashed avocado instead. Replace that mayo you’d usually put on a sandwich with avocado slices. You’ll not only save calories, you’ll be cutting out saturated fat and increasing your daily intake of monounsaturated fat as well.
