I never trusted margarine, always preferred butter. A recent Wall Street Journal article (via The Business of Life) discusses how the body absorbs more vitamins and nutrients when there's butter on your veggies:
"It turns out that some of the best stuff in fruits and vegetables -- certain vitamins and cancer-fighting compounds -- are "fat-soluble." That means some fat needs to be present for the body to adequately absorb the nutrients. But studies are now showing that people who opt for no-fat dressing or who skip adding foods like avocado or cheese to a dish to avoid fat calories, are getting far less out of their salads and other veggies."
"With the salad test, the impact of adding avocado was even greater. The first salad included romaine lettuce, baby spinach, shredded carrots and a no-fat dressing, resulting in a fat content of about 2%. After avocado was added, the fat content jumped to 42%. When the salad was consumed with the avocado, the 11 test subjects absorbed seven times the lutein and nearly 18 times the beta carotene. Lutein is a carotenoid found in many green vegetables and is linked with improved eye and heart health. Study researchers say they were not only surprised by how much more absorption occurred with the avocado added to the meal, but they were taken aback at how little the body absorbed when no fats were present. "
Lay it on, Baby! Stop denying yourselves butter and avocados!
