Flaxseed crackers are a high-fiber healthy snack.

A. Nicola McKeown, PhD, a scientist at the HNRCA, answers: “Like other seeds, flaxseeds provide both soluble and insoluble fiber, and they are also a rich source of alpha-linolenic acid, an omega-3 fatty acid which may have anti-inflammatory properties.”

“It is the soluble fiber inside the seed that helps lower cholesterol. Processing the seeds by grinding or soaking in water makes the fiber easier to digest and helps release nutrients for absorption. The insoluble fiber in the tough outer coating of the seed helps create stool mass and plays an important role in bowel health. Foods made with whole flaxseeds, therefore, are more likely to help with constipation than to reduce high cholesterol.”

“The increasing number of flaxseed products appearing in the marketplace offer an alternative to whole-wheat products (which is particularly important for those with gluten intolerances) and, given the high fiber content of these products, I would say they are an excellent snack alternative to refined-grain products. Make sure you look at the labels to ensure products don’t contain a lot of sugar and that flaxseed is not just a minor ingredient.”
