No matter how much accurate information about nutrition is published, some food and nutritional myths just will not die.
Nutrients are more or less locked in when produce is frozen or canned.
Although drinking hot liquids with high-fat meals may make your mouth feel less greasy, no beverage will keep you from digesting and absorbing the fat you have eaten. Lean meat has less cholesterol than fatty meat. The reason to avoid fatty meat or, at the very least, to trim the visible fat, is that the intake of saturated fat, more than the intake of cholesterol, is what stimulates the body's production of cholesterol and raises levels in the blood. Vitamin C deteriorates when it comes in contact with the air, and the loss of nutrients parallels the loss of flavor. Fresh-squeezed orange juice has the most vitamin C initially, but if it sits around it will quickly be lost.
