In Part 1 of this article about nutrient deficiencies in the gluten-free population, I posed four critiques and questions that I promised to answer in today’s part 2. Without further ado, here we go…
Critique #1 questioned the small sample size of the research. I can’t do anything about that, and there’s not much to be said about it, so let’s move on.
Next, I think it’s easiest to address critique #3: How did nutrient deficiencies in the gluten-free population compare to Americans as a whole? To answer that question, I pulled data regarding nationwide averages from the USDA’s Community Nutrition Mapping Project. If I amend yesterday’s table that showed the percent of the gluten-free population who are deficient in given nutrients, and add to it a column for the national averages, this is what you find:
| Nutrient | GF Deficiency | Nationwide Deficiency |
| fiber | 74% | 92% |
| calcium | 82% | 69% |
| thiamin | 59% | 19% |
| riboflavin | 25% | 11% |
| B6 | 35% | 26% |
| folate | 85% | 40% |
| B12 | 29% | 20% |
| iron | 41% | 11% |
These numbers change the perspective a bit, I think. It’s not simply that the gluten-free population is nutrient deficient. When you compare us to the national averages, it gets slightly more complex. In some cases, such as folate, riboflavin, thiamin, and iron, we’re two or more times as deficient (as a group) than the nation. However, in other cases, such as B12, B6, and calcium, we still have greater rates Read More »

Often times, it seems that people who are on strict gluten free diets get viewed as high maintenance, or picky. The constant need to check and double check ingredients tends to bother some people. The reports of contamination and reactions go unbelieved, and people give that knowing look when “gluten free” is mentioned.
Potassium is a mineral that is easily absorbed by the digestive tract. This micronutrient is essential for life because of the vital functions it performs in our bodies. Normal nerve conduction, muscle contraction, fluid balance, acid-alkali balance, blood pressure regulation, digestion, protein production, and metabolism require the action of potassium. For example, in metabolism potassium is required for the movement of sugars, amino acids, and other molecules into cells.
