Can I Eat Flour Products, Like in Bread?
Although cereal grains at the farm gate are very nutritious, the processing and refining steps that follow usually turn them into packaged products that are now stripped of their nutrients (fiber, vitamins, and minerals) and loaded with salt, oils, sugars, dairy- derivitives, and chemicals. Whereas, whole grains reduce the risk of heart disease, diabetes, cancer and obesity, that box of sugar puffs in your pantry may be doing just the opposite. In general, the more original and unadulterated the grain, the better for you.
I am often asked if there is any harm in using a home-bread-machine to make bread—after all, nothing is added or removed in the processing. For most people whole grain breads are an excellent choice, but it is not the same as eating whole grains. Beating the whole grain more than 1000 times with the whirling steel blade of the bread machine converts the kernel into a powder, known as flour. The intact cell wall of the kernel has been destroyed and now the digestive enzymes (amylase) easily digest the inner nutrients. In addition, the flour has a much larger surface area to volume ratio than did the whole grain, making digestion and absorption much more rapid. For you this physical change may translate into easier weight gain, and higher blood levels of glucose, triglycerides, and cholesterol. The amount of insulin released by the pancreas into the blood is also increased as grains are processed from whole grains to cracked grains to coarse flour to fine flour.23 More insulin can mean more weight gain, and maybe, more risk of diabetes and heart disease. However, compared to animal-foods, free-oils, and plant-parts processed beyond recognition, whole wheat bread is definitely health food.
There have been a few (not many) changes to the program over the years, as with recommended supplements for heart disease, probiotics, etc. Yes, you can refer back to the newsletter on supplements but it does not represent our current position. Several things have changed since the original MWL book has come out and since the MWL newsletter which updated the book.
If you have questions about what we are doing at the program right now (and/or about what I have said or not), the best thing to do is to ask me. I am right here.
We do allow pasta, but like tortilla's, it is one of those very rare "gray' areas on the MWL.
The original MWL guidelines said "No flour products," however, from the beginning, corn tortilla's (made from corn flour) have been allowed in spite of the fact that they have a calorie density of around 1000 cal/lb. Ironically, I have never recommended them as part of my weight loss guidelines because of the calorie density. The same for puffed cereals.
On the other hand, whole grain pasta, also a flour product, was not part of the original MWL program in spite of the calorie density of only around 550-600, almost half of corn tortilla's. However, for 30 years of my career, (including 10 years at overseeing the food and nutrition at Pritikin), I have always allowed WG pasta and people successfully lost weight. In the same study that showed the potato to be the highest in satiety per calorie, whole grain pasta was right behind it (and oatmeal) and above brown rice.
Some say they overeat on it and if you find that to be true for you, then just leave it out, but then again, some say they overeat on brown rice, so, if so, just leave it out.
