Personal chef to Oprah Winfrey, recipient of the James Beard award and best selling author of Back To The Table, Art Smith notes “throughout history humans have sat down together to break bread.” Some designate “manna” as a universal term for bread, the staff of life, translating into distinct cultural terminology including rye, pumpernickel, challah, matzoh, crumpet, brioche, foccacia, biscuit, cornbread and pita. Query the average person and you’ll quickly discover bread is an integral menu staple in most meals—as a breakfast accompaniment (eggs and toast), an “oreo” exterior for luncheon filling (hamburger/bun) and as an appetizer for dinner (biscuits/bread loaf). Since antiquity some form of bread has found its way into human cuisine.

While many “healthier” whole grain breads are infiltrating the marketplace in response to consumer demand, a unique bread “alternative” worth considering for its health and culinary virtues is naturally leavened hearth bread baked in a steamy brick oven. From its inception “desem” bread has been prepared according to centuries old Flemish traditions1 using natural leaven instead of baker’s yeast. Initiated by the Egyptians in 2300 B.C.2 and practiced in Europe for centuries, this time-honored baking practice is worthy of distinction.

From a health perspective, natural food authority Ron Kotzsch suggests that despite our “consummate care,” we have not succeeded in baking traditional bread, citing a myriad of ailments (anemia, rickets, digestive disturbances) linked by modern researchers to our “untraditional” bread making methods.3 And what is the source of our error? Kotzsch points to using the wrong leavening agent— baker’s yeast—as the culprit distinguishing this industrialized “insipid bread”4 from its counterpart, naturally leavened artisan bread. Time for revival of an ancient “skill that will nourish the body and delight the senses.”54

Emergence of Naturally Leavened Bread:
Desem (pronounced “day’-zum”), a Flemish term for “starter,” was first developed in Belgium following WW II in response to public demand for a healthier menu to include bread comparable to European brown bread.6 The distinguishing feature of this sourdough bread is its ferment. A desem culture or starter dough is a living ecosystem unto itself. Through a process of gradual fermentation this product grows into a highly digestible, nutrient dense bread. In contrast to baker’s yeast (a lab grown and controlled singular yeast strain), desem relies on its multispecied ambient microorganisms (including enzymes, lactic acid and bacteria) that naturally occur on the grain.7 For those with health concerns (allergies, digestive disturbances), who consider bread prohibitive in their diet, it is worth considering if it is the bread itself or the ingredients and preparation that influence tolerance, allergenicity and digestibility. Now let us turn to the bread baking site, the kitchen, to review the preparation of this artisan bread.

Naturally Leavened Bread Baking:
Preparing desem bread is more labor and time intensive than conventional bread preparation —it’s an art that doesn’t take shortcuts. The quality of the finished product, however, justifies the initial time investment and reflects the love of the baker’s craft. Desem bread baking requires following simple yet critical guidelines: pure water, quality salt, fresh ground organic flour, leaven (desem) and strict avoidance of contaminants.8 The emphasis here is on freshness and purity of product coupled with nurturing the process (from start to finish) that determine the final product’s integrity—the life force of the bread. Organic grain must be ground fresh to preserve nutrients. Pure water is imperative to avoid chemical contamination (affecting quality and taste).

Few people realize the hefty differences between naturally leavened and yeast risen bread nor the effects of the raw materials on overall health and vitality. These differences are even more significant when comparing commercial white to naturally leavened bread—one is a starch filler (whose germ and bran are removed to extend its shelf life at the expense of its nutrients) while the other is a nutrient dense staff of life meal.

Commercial flour is bleached and processed. It can contribute to various mineral deficiencies and health ailments. Within hours of grinding flour, nutrients (vitamins, minerals and enzymes) fall prey to oxidative damage, including fatty acids that readily become rancid. Additives (sugars, caramel coloring) may add uniformity in color to bread loaves but hardly contribute to its nutritional integrity. 9,10

Advantages of unleavened bread over yeasted breads:
Yeasted breads rise quickly, driven by a refined single yeast strain developed under controlled lab conditions. In contrast, naturally leavened breads rise and expand over time by the action of the desem or fermented starter that is continuously reinoculated during the leavening cycle. A symbiotic relationship develops between the “family” of friendly bacteria as it feeds on the nutrient dense whole grain and the mineral-rich salt, while the leavening of the bread develops a wholesome, fine-grained moist texture.11 Additionally, the need for fats (oils), dairy and sugars is unnecessary. They are replaced by the inherent germ oil from the freshly ground organic whole grain and the sweet taste imparted by the natural sugar complex in the grain.12

During the sourdough process the bread is proofed (allowed to rise), bran flour breaks down and nutrients are released into the dough. Specifically, the phytic acid in the seed grain is 90 percent neutralized, a requirement for minerals residing in the bran to be released and absorbed.13 This is in stark contrast to conventional yeasted breads where 90 percent of the phytin remains—to digest or not to digest, that is the question.

Once “proofed” over several hours, the unleavened dough expands, yielding its characteristic slightly sweet, moist, chewable texture. One can bite into such a bread and feel satisfied from eating a nourishing product that appeases both one’s appetite and senses.

Another highlight to naturally fermented bread is its digestibility. Sourdough bread maker and author Meredith McCarty notes that with sourdough bread proteins are broken down into their simpler amino acid form and complex carbohydrates are digested into simpler sugars.

Enzymes that develop during the proofing process remain intact throughout the baking time since the bread loaf center bakes at a cooler temperature than the crust.14 A caveat: Although we refer to this bread as “sourdough,” in Europe it is called “leavened” instead of yeasted bread. When prepared properly however, the flavor is not sour.15

If yeast-related allergies make bread consumption prohibitive, this side note may help. It is the beneficial bacteria in naturally leavened bread (Lactobacillus, for example) that enhances its digestibility. This improves digestion, absorption, and assimilation in addition to monitoring Candida (the opposite effect of baker’s yeast, which favors the Candida organism).16,17

Allergic to Bread?
Complete avoidance of bread products due to sensitivities is a common complaint whether due to wheat or yeasted breads. If you consume processed grains such as white flour bread, you may be reacting to the flour, chemicals in the grain18 and preservatives used to increase shelf life instead of the bread itself, in addition to experiencing blood sugar fluctuations from white flour’s high glycemic index. Or you may be reacting to the leavening agent—baker’s yeast. Try switching to organic naturally leavened hearth bread and test the results to determine allergenicity. If you have a medically determined known allergy or health malady (celiac sprue) to WORB grains (wheat, oat, rye and barley), consider naturally leavened wheat bread alternatives including spelt and kamut. Many find increased tolerance to these heirloom grains as opposed to hybridized grain berries. Or, if you are baking your own bread via this method, try a combination of grains including amaranth, buckwheat and brown rice, in addition to kamut and/or spelt.

Closing Thoughts:
Desem bread is a work of art from start to finish, drawing “its excellence from the marriage between the baker’s skill and the natural goodness of the bread.”19 Once the initial leaven is prepared (from a mixture of flour and water that is fed over several weeks), it can last for a lifetime if it is maintained through weekly “feedings” and provided with conditions that favor its growth. From then on, each baking session consists of grinding fresh organic grain (preferably milled in a stone-burr grist mill), mixed with pure water and sea salt, transitioned through proofing phases, ultimately baked in a wood fired brick oven to yield a full bodied crusty, chewy, crumb savory bread.20 A portion of leaven is reserved from each batch to reinoculate the next bread baking dough.

While many “healthier” whole grain breads are infiltrating the marketplace in response to consumer demand, a unique bread “alternative” worth considering for its health and culinary virtues is naturally leavened hearth bread baked in a steamy brick oven.
For home bakers unable to access a brick masonry oven21 or grist mill who wish to prepare this artisan bread, one can simulate this method using a conventional oven and a ceramic cloche baker available from Sassafras Enterprises, Inc. Hand or electric grain mills are available commercially as well.

A number of yeast-free bakeries have popped up nationwide, exclusively devoted to baking naturally leavened hearth breads including spelt and kamut varieties. Preventive medical doctor Hy Lerner of Baldwin Hill Bakery in Massachusetts opened the first commercial natural leavened bakery in the 70s and in so doing found his ultimate life’s niche— trading in his white lab coat for a white baker’s apron and cap. Check with your local health food store for brand names or companies that provide mail order service.

There are “distinct positive changes and healing that occur when bakers unite in the kitchen to bake.”22 It is no wonder the totalhealth editor has recognized the cathartic experience and stress-reducing benefits of this hands-on nurturing craft. A theme resonating among bakers of naturally leavened bread baking is their intrinsic sense of connectedness to their craft, their deep sense of satisfaction derived from producing a homespun product subject to their individual discretion, molded at the hands of its potter from culture to crust. While in the driver’s seat, the baker is a powerful instrument directing with a gentle hand the entire performance combining the ingredients of care, patience and nurturing. It is our positive traits concentrated into this fine art that reflect back when we bring our best manna to the table.23

Desem bread is a story of rebirth experiencing a new heightened popularity as artisan bread baking steeped in tradition reaches its long-awaited crescendo into mainstream bread baking. While there is a science to fermentation, in the end, “methods and rules are not as useful as understanding the process of naturally leavened hearth bread baking,” notes Daniel Wing, M.D. “A baker who understands the process is liberated—free to create new recipes and to manipulate the determinants of bread quality in pursuit of his or her perfect loaf.”24 Test the process for yourself to determine whether the proof is in the pudding.

To your good health and happy baking— naturally.
