If you have to cook for me at any point, or if you're simply curious, here is a list of what I can, cannot, and should not eat.

CANNOT:
Bell Peppers: red, green, yellow, orange, etc. (wicked painful but not deadly allergy)
Celery (mild allergy)
Wheat (intolerance/addiction)

SHOULD NOT:
Sugar of any type: white, brown, icing/powdered, molasses, honey, maple syrup, brown rice syrup, (evaporated) cane juice, agave nectar, sugar substitutes, sugar alcohols, corn syrup, fructose, glucose, sucrose, dextrose, maltodextrin, xylitol, sorbitol, maltitol, aspartame, asulfame-K, saccharin, any combination of the above, etc. (intolerance/addiction)

Please leave it up to me to decide whether I want to cheat. If I do cheat, it will likely be with sugar, though rarely with wheat. Never with the celery or the bell peppers.

NUTS & SEEDS
The middle column indicates Protein/Carbohydrates/Fibre per ½ cup serving, unless otherwise specified. Number at right is Protein/Carb Ratio; the higher the number, the better it is for me. Figures ganked from Nutrition Facts.

LEGUMES:
In Moderation:
I like all beans; however, they MUST be well-cooked -- no dried beans, please. Also, canned baked beans are a no-no -- they always have sugar. Read the labels, please!

GRAINS:
In Moderation:
Non-wheat grain (in any form): white rice, brown rice, corn, oats, millet, barley, buckwheat, amaranth, quinoa, teff, spelt, kamut, rye

EGGS & DAIRY:
I am not lactose intolerant, so dairy is fine in that respect; however, I do not like to rely on eggs and dairy as a staple source of protein. Also, due to a slight yolk-sensitivity, I prefer eggs scrambled or in omelette form, and only once per day/every other day.

MEAT & FISH:
Best:
Salmon (not canned)
Tuna (not canned)
Mackerel (not canned)
Venison

Good:
Poultry
Beef (Not Veal)
Goat
Lamb
Canned Tuna & Salmon
Other Fish
Other Game

In Moderation:
Bacon
Crab (NOT FAKE!)
Lobster (NOT FAKE!)

NB: I don't like and won't eat sardines or other canned whole fishes. Smoked whitefish is excellent, and I can eat it any time. Smoked salmon, however, is usually cured with sugar and must be eaten in moderation. Please check labels. Also, shrimp and shellfish are yucky.

"In Moderation "
Moderation for me means no two "in moderation" items in any one meal, and then, only in small amounts: ½ a cup is about right for solids

VITAL TIDBITS:

Soy sauce
Store-bought soy sauce typically has wheat. You can buy wheat-free soy sauce at most large grocery stores and at health food stores.

Vinegar
Please use sparingly, no matter the type. If you're considering a salad dressing, I would prefer it to be based on or consisting only of lemon or lime juice.

Fruit juice
I avoid apple, grape, and pear juices, as these juices are sweeter than my palate can stand, even diluted. All other fruit juice must be unsweetened, and (when I'm being good or am not in need of the fruit sugars) I prefer a 40% juice to 60% water dilution. When in doubt, ask or allow me to serve myself.

Soy
I can drink soymilk, provided it's unsweetened. I enjoy Soy Nice original and unsweetened. I can also eat tofu. I love the stuff, actually. And edamame, soy beans in the pod, are delicious!

Processed Foods
Foods like fake meat, cheese slices, rice mixes, pre-packaged taco seasonings, etc., are all verboten as there are invariably ingredients contained within that I cannot eat. Processed cheese slices typically have sugar; fake meats have wheat or red bell peppers; taco seasonings usually have wheat and/or sugar; hot dogs (er, should this be under fake meat?) have sugar and other bad-for-everyone stuff. It's just best to hand me a carrot and some peanuts. I'll be fine. Really. I will.

Condiments
Mayonnaise, mustard, steak sauce, barbecue sauce, salad dressings, salsa, pasta sauce, prepared horseradish, etc. almost always have hidden sugars. Some don't, so read the labels!

Cake baking
Yes, I can still eat cake! Provided, of course, that there's no wheat in and the sugar content has been sufficiently diminished. When baking for me, nut flours are best. If you're looking for a suitable sweetener, brown rice syrup is superior; however, please use sparingly, as always. Applesauce makes a fine substitution for oil in cake recipes, plus it adds more sweetness.

Bread
I can still eat bread, too! Wonder of wonders! I have a strong preference for Shasha Bread Company's Spelt sourdough. Sourdough needs no sugar and does not contain the same type of yeast that regular bread contains, so it's healthier for me. However, because of the carbohydrate content, I can only eat 1 or 2 slices in any given day. Still, it's yummy, yummy stuff.

Alcohol
Usually avoided. Clear spirits are not too horrible with respect to the hypoglycemia. Flavoured liqueurs are right out, since they're mostly liquid sugar. I avoid alcohol not just because of blood sugar issues, though: I'm not entirely sure why, but it inflames my sinuses, making it difficult to breathe and, as a result, I get a li'l sleepy, which is no fun.

HANDY TIPS

To Thicken Sauces
Instead of using regular wheat flour, try corn starch, rice flour, arrowroot flour, or tapioca flour. Large amounts of flour, regardless of the type, is not good for my hypoglycemia, so please take this into consideration when planning meals.

Sweeteners that I can use:
Food-Grade Vegetable Glycerin (in rather small amounts: about ½ teaspoon per serving)
Cinnamon (LOTS of it -- 1tsp+)
Apples (chopped in oatmeal, sauce also in oatmeal or in cakes)
Bananas (chopped in oatmeal, used also in tofu pudding)
Strawberries (anywhere I see fit)

Whipping Cream
To sweeten, use glycerin-based vanilla (expensive, but sooo yummy!) or regular, food-grade glycerin.
1 tsp - ½ tbs per whipped pint of whipping cream

Plain Yogurt
This stuff is good with just about anything. I use it on fruit, on white potatoes, on sweet potatoes, in place of sour cream in borscht, on tacos, in Indian food, etc. Guess it's good I like sour things, though I do prefer the high-fat versions. :)
