It is a well known fact that whole-grain foods keep triglycerides in their limits and keep a check on them. Advancing a step further, a study by Agricultural Research// Service scientists in California provides the know-how as to how whole grains do that.

According to ARS chemist Nancy L. Keim, "Lipoproteins are the body's means of moving lipids to muscles, where they're used for energy, or to fatty tissue, where they're stored as reserves.”

It is known in health sectors that High density lipoproteins are good, while low-density lipoproteins are bad.

An investigation into the effect that whole-grain foods and refined grains have on lipoproteins was conducted by Keim and colleagues.

Participants were 10 women, age 20 to 45; who volunteered for the study each completed a whole-grain regimen and a refined-grain stint. The first 3 days of the whole-grain phase, the volunteers ate six to eight servings of whole-grain foods a day, on average.

Next came the refined-grain regimen, when the women ate foods such as a refined-grain cereal at breakfast, white rice with their evening meal, and graham crackers for the after-supper snack.

On the fourth and final day of both stints, the women came to the nutrition centre to eat breakfast. Blood samples before their meal and at three intervals afterwards were collected by the investigators.

Lipoproteins were separated out using an ultracentrifuge. The finding was that very low-density lipoproteins (VLDL) contained significantly more triglycerides following the refined-grain test breakfast than after the whole-grain test breakfast. Additionally, after the refined-grain test meal their VLDLs had significantly higher levels of a worrisome protein called "apolipoprotein CIII" (apoCIII).

"In medical studies, apoCIII has been associated with high levels of triglycerides and increased risk of heart disease. It's also been shown to interfere with the work o
