Keeping blood sugar levels in check can be much easier if you eat the right foods. The trouble is that many people are accustomed to eating foods that can send blood glucose levels soaring. So the biggest glucose-control challenge may be simply remembering which foods help control glucose and which ones don't. Keep in mind that the benefits of learning about glucose-controlling foods and remembering them may save your life. High glucose levels increase risk of cancer,1 cardiovascular disease,2 Alzheimer's disease,3 and death.4
What's really fun is discovering delicious new foods and recipes that keep glucose low. As people move away from foods flavored with sugar, salt, and fat, they enjoy what they eat more than ever: They taste the foods' natural flavors. They love the increased energy they have, too. They are more productive and have more fun—rather than feeling tired and not wanting to do much.
Foods to Choose and Foods to Lose
You'll want to become familiar with the Glycemic Index (GI), which ranks carbohydrate-rich foods for their effect on blood glucose. While not infallible, it is an excellent guide for beginners to find the likely effect of their favorite foods on blood glucose.
Foods to avoid include those rich in easily digested starches or sugars, such as:
- Dates
- White bread and whole grain bread
- Watermelon
- White potatoes
- Most grains-including rice, millet, and oats
- Sugar in any form-for example: brown sugar, agave, and molasses
- Standard pastas, made of flour-no matter what they are flavored with
- Corn
- Chips
- Pancakes and waffles
- Rice cakes
- Most fruit juices-except lemon, lime, or grapefruit juice
- Pizza
Foods to Choose
Hundreds of delicious low GI foods await you: Most berries, beans, non-starchy vegetables (kale, collards, bok choy, broccoli, squash, tomatoes, etc.) and nuts work well. If you want to eat meat or fish-choose low fat, high-quality meat and fish that are from non-polluted waters and are high in omega-3s.
Understanding Labels is a Key
When selecting a food to include in your healthful low GI diet, don't be fooled by labels. Some marketers will try to make you think a food is good for glucose control when it isn't at all. Food with "LOW CALORIE" or "NO SUGAR" on the label may still be loaded with high GI starch that will send glucose skyrocketing. Remember: Starch often has as much effect on blood glucose as sugar itself, so always look at the amount of total carbohydrates rather than only total sugars.
If a food has more than 16 grams of total carbohydrate per serving, be cautious - especially if it is a juice, which is extremely easily digested.
And while it's true that some of them-like fructose and high fructose corn syrup-won't raise your blood glucose as much as sucrose (table sugar), they may have even worse effects.5,6
Tricky Labels
Here is an example of how phrases on labels can trick you.
"GOOD-FOR-YOU CEREAL"

JUST TWO GRAMS OF FAT!
LOW SUGAR!
ALL-NATURAL!
Overall tip: Beware when ingredients are provided in such small print that only Superman could read it. That can mean they are trying to hide something.
Knowing Your Glucose Levels
Knowing the effect of your food on your blood glucose levels is very important. To learn this, test your glucose level before and after a meal. That requires a glucometer, also known as a blood glucose meter. Don't hesitate to check your blood glucose whenever you need to. Making sure that the food you eat keeps blood glucose low offers huge rewards. Well controlled glucose may activate your adult stem cells - helping to rejuvenate every organ in your body!7
Aim for fasting glucose levels in the 80s or below and postprandial levels, measured two hours after eating, of not more than 120 mg/dL. If you have type 2 diabetes mellitus, you can aim for a fasting glucose goal of 100 mg/dL or below and a postprandial limit of 130 mg /dL.8
If you are unsure about how a food will affect your blood glucose, use your glucometer to test the glucose-level effect of the food. Make sure to be scientific about it:
- Test to determine your glucose level before eating.
- Eat your test food.
- Test again 30 minutes after you finish eating the food. If your glucose has risen more than 20 mg/dL (40 if you have diabetes), this food will hinder your glucose control efforts.9
Making Glucose Testing Affordable
The most expensive aspect of glucose testing is the cost of test strips - the way glucose-testing-supply companies make money. When you visit your doctor, try to get a prescription for glucose testing. This is likely to reduce the cost of purchase. You can take the prescription to your local pharmacy and in many cases redeem it for a free blood glucose meter so you can get started at no cost. You can also ask if your doctor will give you some of the samples that pharmaceutical reps provide.
Another way to get started for free is to check to see which of the big diabetes companies offer free getting-started kits. They will to give you the glucometer, hoping you will buy their test strips. Keep in mind that the cheapest isn't always best. Ask your doctor for a glucose-testing-system recommendation.
Glucose Control Program
The importance of glucose control drove the development of THE CR WAY TO GREAT GLUCOSE CONTROL Program. It includes a 5-part CD and live teleconferences, where the practical application of glucose control is presented by glucose control experts - Paul McGlothin and Meredith Averill. Plenty of time for your questions to be answered is integrated into each conference.
This hands-on CR Way program provides two sets of glucose control meal plans:
The Optimal Health Plan
For those without diabetes, who want to control glucose for optimal health: Increased cognition, disease prevention, and - ultimately - more energetic, healthier living are emphasized.
The Reversing Type 2 Diabetes Plan
Scientific evidence shows that type 2 diabetes may be both preventable and reversible with a CR Way-based diet.10,11 This plan offers foods and recipes that can help lower blood glucose for those who have special glucose control issues.
Lower Glucose: Better Life
When you decide to follow a low GI, CR Way lifestyle, get ready for increased mental and physical capabilities. And watch out for the likely side effects of extra BDNF, a brain-improving molecule that will make you happy - possibly even giddy - and improve your learning speed and memory.12 Other beneficial molecules will probably kick in too with another host of benefits, such as lower blood pressure and loss of extra fat. 13 Your new, energetic lifestyle will make it easier to do the things you want to do, and research indicates14 you will likely live longer.
