Rice Bran Protein Beneficial For Diabetes

Rice is a widely consumed grain around the world, especially in Asia and Africa.

It’s a rich source of energy and protein, and it’s among the top three food groups that are the main protein supplies in the human diet.

Rice bran is a byproduct of the milling process of rice and it’s produced from the outer layers of the rice grain.

Ricebran is very nutritious. It contains 13.4% proteins, 19.6% lipids, 20.5% dietary fiber, and other functional compounds.

Some of these compounds are believed to have antioxidative, aunty-diabetic, and lipid-lowering effects.

The lipid content in rice bran is usually used for rice bran oil production, whereas the protein content has been mostly used as a fertilizer and animal feedstuff, but not in the human diet.

A recent clinical trial published in the Journal of Functional Foods has investigated the effects of rice bran protein on diabetes and liver disease.

Let’s see what they found.

What’s Important

Diabetes is a very common serious disease worldwide, and strategies for its treatment and prevention are constantly being discussed.

Diabetes can cause many complications, like neuropathy, vision problems, and fatty liver disease.

Therefore, the prevention of these complications is crucial.

Scientists believe that dietary protein restriction is the most effective way to slow the progression of this disease.

In line with this, previous research reports that plant proteins can slow down diabetes. [1] [2] [3]

The Details

This was a mouse model study and it lasted for 8 weeks during which two groups of mice were fed either a dairy protein or rice bran protein.

Here are the results:

  • In comparison to the dairy protein group, the amount of accumulated fats in the liver in the rice bran protein group was significantly lower;
  • The overall liver function in the rice bran protein group was notably better;
  • Some markers for systemic inflammation were lower in the rice bran protein group;
  • In comparison to the dairy protein group, there was an improvement in insulin sensitivity and regulated blood glucose levels in the rice bran group;
  • Rice bran protein also demonstrated possible protective effects on the kidney.
  • Bottom Line

    Considering the richness of nutrients present in rice bran, the results from this study shouldn’t come as a surprise.

    It’s clear that rice bran protein has some very positive effects on diabetes and its complications, however, as with every novel study, more studies need to be conducted for these effects to be confirmed.
