Can I eat whole wheat bread?

I get this question often. People read or hear the words ‘whole-grain’ or ‘whole wheat’ and think its “healthy”. You know me, I’m a proponent of a low carb food plan for healthy living. Most people think corn is a vegetable so I don’t expect clients to understand grains. My suggestion is to avoid grain foods. There are no low-glycemic whole-grain foods.

Most of my clients have heard about the glycemic index. This index categorizes foods that contain carbohydrates. It lets us know which foods raise blood sugar levels the most to those that raise blood sugar levels the least. The top four categories are:

1. Cereals
2. Breads
3. Other grain products
4. Pastas
5. Desserts
6. Fruits

In other words, cereals, breads and pasta generally produce a bigger rise in blood sugar than desserts or fruits. “Wholesome” whole-wheat bread has a glycemic score of 80. That is twice the score of ice cream, apples, or peaches!

The bottom line: Whole-grain bread spikes your blood sugar the same as white bread does. High-glycemic foods cause inflammatory reactions, contribute to extra fat, and accelerate aging.


Long-Term Metformin Treatment Linked to Vitamin B12 Deficiency

May 2010 — In type 2 diabetes, long-term metformin treatment is linked to vitamin B12 deficiency, according to the results of a multicenter, randomized, placebo-controlled trial reported Online First May 20 in the BMJ.

”Metformin is considered a cornerstone in the treatment of diabetes and is the most frequently prescribed first line therapy for individuals with type 2 diabetes,” write Jolien de Jager, from the Academic Medical Center in Amsterdam, the Netherlands, and colleagues. “Metformin does, however, induce vitamin B-12 malabsorption, which may increase the risk of developing vitamin B-12 deficiency — a clinically important and treatable condition.”

“Long term treatment with metformin increases the risk of vitamin B-12 deficiency, which results in raised homocysteine concentrations,” the study authors write. “Vitamin B-12 deficiency is preventable; therefore, our findings suggest that regular measurement of vitamin B-12 concentrations during long term metformin treatment should be strongly considered.”

Dr. Tucker’s comments: Dietary counseling should be considered with every person on Metformin. I know eating a low-sugar diet can be difficult. A new formula called Glucorest contains touchi extract which has been shown to blunt the glycemic response and supports healthy glucose and triglyceride metabolism – without reported adverse effects. Order Glucorest from the Metagenics link.
