  1. Fog

    Sergio_150601_1542The fog comes

    on little cat feet.

    It sits looking

    over harbor and city

    on silent haunches

    and then moves on.

    Carl Sandburg (1878 – 1967)

     

    The fog of San Francisco is a distinctive characteristic of that beautiful city. It can make the sun, the Golden Gate Bridge and tall buildings and trees disappear before your eyes! This famous fog also carries colonies of a local bacterium called Lactobacillus San Francisco. It is the secret ingredient of another well-known feature of San Francisco: its sourdough bread.

    The basic ingredients of any bread are flour, water and yeast. The yeast, when hydrated, Sergio_150603_1635feed on the starch in the flour, increasing them in size and number (budding). As this process continues, the flour mixture ferments, producing what we call a “dough.” We shape it, bake it and then eat it. Most of us love the taste of this final product, bread.

    But when bacteria enter the usual mix, magic happens. They produce lactic acid during fermentation and give the resulting dough a tangy or “sour” taste when baked. This is what the Boudin family discovered quite by accident when they left Paris and set up a bakery to serve both locals and gold-rush prospectors in San Francisco in 1849. They thought they were preparing their Parisian recipe for baguettes. The San Francisco fog, however, heavy with wild Lactobacilli San Francisco, unwittingly changed their recipe forever. Their new and unique sourdough bread became an instant hit.

    Today sourdough bread is enjoyed throughout America and beyond. Its high acidity (pH 4.0 – 4.5) makes it a good low glycemic carbohydrate choice (GI 48 – 57). It moves slowly out of the stomach and into the small intestine gradually releasing glucose into the bloodstream. This is good news for blood glucose control, satiety, weight management and energy endurance.

    You can use sourdough bread as you would any other type of bread. I like grilling thin slices of it rubbed with raw garlic and then drizzled with extra virgin olive oil

  2. Sourdough Bread: Delicious, Versatile and Low GI

    photo35_SnapseedI recently visited the Culinary Institute of America in Hyde Park, New York to attend an artisan bread-making class (spoiler: there was a lot of white flour in that teaching kitchen!). My main goal for this experience was to learn bread-making techniques and the food science behind them from the professionals, in this case, Chef Juergen Temme, CMB. To my delight, I reached my goal – and then some. Chef described the ingredients and procedures for five different types of dough, including sourdough, the one low GI white bread out there. I was “all ears.”

    The GI experts explain that acidic foods empty more slowly from the stomach, resulting in a slower release of glucose into the bloodstream. I asked Chef what were the pH values (degree of acidity; the lower the number, the more acidic) of the breads we were baking that day. All of them were made from white flour and all had a pH between 5.0 and 6.5, except for the sourdough bread: its pH was 3.6!

    This is why sourdough bread is a good bread choice for anyone attempting to control blood sugar, weight, and energy. The fuel it turns into lasts longer, preventing blood sugar spikes and helping to ward off hunger. And did I mention how delicious it tastes straight out of the oven?


Gushers vs Tricklers


"Gushers" are quickly-digested carbohydrates that cause a rapid rise in blood glucose and fuel appetite.

"Tricklers" are slowly-digested carbohydrates that are gradually released into the bloodstream and sustain satiety. These are the good carbs.
