About Flaxseeds

One tablespoon of whole flaxseeds provides approximately 53 calories, 1.8 grams of protein, 2.9 grams of carbohydrate, 4.2 grams of fat, and 2.7 grams of fiber. Because nearly all of the carbohydrate is fiber, the serving contains only about 0.2 grams of net carbohydrate.

Flaxseed nutrition is notable for alpha-linolenic acid (ALA), lignans, thiamin, magnesium, manganese, copper, and phosphorus. Grinding the seeds improves access to their oils and other nutrients.

Mix ground flax into oatmeal, yogurt, smoothies, batters, or bread dough. Drink adequate fluid and increase the amount gradually because a sudden rise in fiber can cause gastrointestinal discomfort.
