Nancy Dell: Natural Eggshell Membrane; Best Margarine

CHICOPEE, Mass. (WWLP) -  

1. I saw an ad for Natural Eggshell Membrane to ease joint pain. Does it work?
Casey, Internet

Natural Eggshell Membrane is a supplement with proteins that rebuild cartilage and other ingredients similar to human joints.

In one study of 39 participants, Natural Eggshell Membrane increased joint flexibility 27 percent in one week and reduced general pain 72 percent in one month. So the research looks promising but experts say more research is needed to verify these results.

In the meantime, the supplement SAMe has more research behind it. SAMe helps to maintain cell membranes.

Studies show it can reduce morning stiffness, pain and swelling as much as non-steroidal anti-inflammatory drugs. SAMe can also improve range of motion and how fast you can walk.

What about weight control for healthy joints? No supplement can take the place of maintaining a healthy weight and getting some exercise to keep your joints healthy.

2. Which margarine is best?
Lisa, Agawam

There must be 100 brands of margarine on the market. Recently the consumer group Center for Science in the Public Interest rated margarine.

The top ratings went to those with no hydrogenated oil. Surprisingly, 29 of the margarines tested still had hydrogenated oil.

The top ones also keep the saturated fat to 1 and a half grams and no more than 50 calories per tablespoon. The margarine that meets the guidelines and has the best taste according the reviewers is Country Crock Light.

Also on the list are Olivio Light, Promise Light, Smart Balance Light, Brummel and Brown, and I Can't Believe It's Not Butter Light.

What about Land O Lakes Light Butters? They almost made the top list. They have 2 grams of saturated fat per tablespoon. The top ones had 1 and a half grams of saturated fat.
