Sprouted grain products are all the rage. But does sprouting a grain improve its nutritional value?
Scientists Chavan and Kadam analyzed a lot of nutritional data on sprouts in a review article that was published in that old page-turner, Critical Review of Food Science and Nutrition. While they acknowledged that sprouting did increase B-vitamins and certain amino acids and increased digestibility, they ultimately conclude that “the magnitude of the nutritional improvement…is not large enough to account for in feeding experiments with higher animals.”
In other words, although you can measure the difference in the seed, you can’t really measure a difference in an animal that eats the seed.
And in his stirring piece, entitled Cereal Sprouts: Composition, Nutritive Value, and Food Application, researcher K. Lorenz observes that “most of the increases in nutrients are not true increases…They simply reflect the loss of dry matter…during sprouting. Animal studies… have failed to show a superior nutritive value of sprouted grains over ungerminated grains. Studies with humans are not likely to produce more encouraging results.”
Wow, what a killjoy!
As far as the superior nutritional quality of sprouted grains goes, the super science-y guys clearly aren’t buying it. But the pro-sprouters seem to have a lot of impressive and scientific- sounding data as well. As a final step, I checked the nutrient database on NutritionData.com to see if I could see any nutritional differences between sprouted and unsprouted grains.
Just the Nutrition Facts, Ma’am!
Here’s what I found when I compared the nutrient values for unsprouted wheat kernels to those of sprouted wheat kernels. Calorie for calorie, the sprouted wheat was slightly higher in vitamin C, a couple of B-vitamins, iron, and calcium. The unsprouted wheat was quite a bit higher in fiber and protein, although the protein quality was slightly lower. And everything else was about the same. (I’ve included links in the show notes to the nutrient analyses, if you’d like to look at them.)
So, sprouted grains are higher in some nutrients, a bit lower in others. However, those minor differences may not add up to much—especially after they’ve been processed and baked into breads and other products. As I said before, sprouts are fun and nutritious! But what about that sprouted wheat bread that so many of you have asked me about? Looks like it may not be quite as miraculous as some would have you believe. But I still think it’s a nice way to get your whole grains. Enjoy it in good health!
