| When
I discovered that Type 2 Diabetes is essentially
a nutritional disease, it seemed very important to determine what
I should eat. I quickly discovered that there is quite a bit of disagreement
about which diet
is best for diabetics. This disagreement centers around the consumption
of the dietary macronutrients carbohydrates,
protein, and fat.
A general principle of life seems to be balance in all things; I decided
to apply this principle to choosing a diet. After some research, I
found Barry Sear's arguments in The
Age-Free Zone the most
persuasive and the diet he advocates the most balanced.
In January 2001, I started
myself on a diet based loosely on the Barry Sears Zone
Diet and the Fresh
Start Metabolism Program by Cathi Graham. My main food targets
are 1800 calories/day with each main meal spaced 4-5 hours
apart and made up using 15g fat/ 30g protein/ 45g carbohydrates
(note the 1/2/3 ratio and that this
equates to 30/30/40% calorie
contribution ratios; using 1g fat=9 calories
and 1g protein or carbohydrate=4 calories).
I eat a variety of foods and try to eat carbohydrates with a low
glycemic index. I also started
myself on a vitamin/herb supplement
regime based largely on the recommendations made by Kathi
Mead, ND, in Natural
Treatments for Diabetes. I started recording everything I eat
and my blood glucose levels before and after every meal; for example,
see a typical breakfast
and an excerpt
from my Food Diary. In January 2002, I started recording,
but didn't keep it up, what I eat using Diabetes
Diary and producing weekly
nutrition reports. Once my diet has become a normal routine,
I intend to start an exercise
program (I've been saying this for two years now, I guess I'd better
get going soon!)
I would say that over 80% of
bringing your diabetes under control is directly related to what
you eat. The other 20% is due to exercise,
medications, and supplements.
There are no magic cures, no magic pills, natural or synthetic,
just a simple remedy; control what you
eat before you experience the complications
associated with diabetes!
Diet
Guidelines...
The following guidelines assume
that you don't have special physical needs which may be unrelated
to Diabetes. For example, if you have kidney problems, you may have
to limit the amount of protein in your diet. In any case, always
seek the advice of your doctor, registered nutritionist or dietician
before initiating any major change in your eating habits.
- Start a Food
Diary. Record when and what you eat and drink throughout the
day. I use a small spiral-bound notepad to record what I eat and
then input the information into my Sony
SJ-20 using RMRdiet
and then transfer my results to my PC for analysis and report
creation using Microsoft Excel. Eat small meals at least
every 4 to 5 hours (and preferably more frequently). Record how
you feel during the day. Record you blood glucose level immediately
before and two hours after each meal. Set premeal and postmeal
blood glucose target levels (see Using
your meter).
- Estimate
your daily protein requirement based
on your weight, percentage body fat, and physical activity level.
Record your height, weight, waist, hip, and wrist measurements
and then use the
Zone Body Fat Calculator.
- Reset your metabolism using
the method suggested in the Protein
Diet. Eat your protein requirement plus 50g/day
of low-glycemic carboydrates,
spread throughout the day (the Protein Diet recommends
30g/day but this is insufficient
to prevent ketoacidosis);
continue this until you have reached your desired weight and fat
percentages, and your blood glucose levels have been normalized
and stable for at least 4 weeks.
- Increase your carbohydrate
intake in 10g increments/week until every meal and snack
calories are balanced in the ratio 30% fat/
30% protein/ 40% carbohydrate (1g/2g/3g ratio).
If you are taking insulin, you may find it easier to control and
predict blood glucose swings due to carbohydrates, so you might
want to consider increasing your carbohydrate percentage.
- Consider using vitamin and
food supplements
(probably needed to minimize future diabetic complications);
as a minimum add B6, B12, folic acid to lower your homocysteine
level and your risk of heart disease (see ref#36
to ref#52); a multivitamin
(see ref#54); at least 30g/day
of Whey Protein Isolate to improve
your immune system (see ref#55
to ref#68); and 1
tbsp/day of EFA (see ref#69).
- Limit carbohydrates
to foods with a low glycemic index
(see ref#70 to ref#78).
I'm using a Palm-based Glycemic List
SmartList database to help determine which carbs to eat. For
example: chana
dal (GI 8), available in Canada
from Loblaws
and the Real Canadian Superstore (owned by Loblaws); pearled
barley (GI 25); beans (GI
34); lentils (GI 30); cheese;
milk (GI 32); low fat, artificial
or unsweetened, yogurt (GI 14); rice:
long-grain parboiled (GI 48) or brown
(GI 55); potatoes: boiled,
steamed or roasted, low-starch new potatoes (GI
60); apples (GI 38); blueberries;
grapes (GI 46); pears (GI
37); bread: whole-grain pumpernickel (GI
51), whole-wheat pita (GI 57),
sourdough (GI 52), whole-grain breads
(in Canada, I find Loblaws
President's
Choice Bran Loaf [2 slices: 103cal, 1.5g fat, 5.5g
protein, 17g carb-4g fibre] and Multigrain Loaf [2 slices:
110cal, 1.7g fat, 4.6g protein, 19g carb-3g fibre] very good);
if you can find them in your area, try the Natural
Ovens and Healthy
Choice breads; soups: tomatoe (GI
38), lentil (GI 44), split
pea (GI 60); cereals: Kellogg's
All-Bran Buds (GI 45), Raisin Bran
(GI 61), Special K (GI
66), and Frosted Flakes (GI 55,
this surprised me; but I tried it and my blood glucose level didn't
rise any more than it did with oatmeal); Quaker
Oat Bran (GI 50); McCanns
Irish Oatmeal (GI 49). Combining
high and low glycemic foods gives you a glycemic index somewhere
in the middle; for example, combine 1 cup of brown rice with 1/4
cup of pearled barley and boil in 2 cups of water for about 45
minutes (makes 3 servings), to get an excellent side dish that
affects my postmeal blood glucose levels significantly less than
rice alone; in addition, you don't get sticky rice!
- Limit your food intake to
between 1500 to 2000 calories per day,
if you aren't expending large amounts of energy!
- Minimize your intake of
processed grains and refined foods. Eat organically grown whole
foods and as much raw food as you can (I mean fruit and vegetables;
not raw meat!)
- Minimize your intake of
all sugar and high-sugar foods; this means candy, cookies, cakes,
pastries, ice cream, frozen yogurt, fruit juices, and soda. Minimize
your use of artificial sweeteners (Aspartame:
NutraSweet, Equal, Canderel, Neotame;
Sucralose:
Splenda; Acesulfame-K:
Sunette, Sweet & Safe, Sweet One; Saccharin; Cyclamates). Avoid
Stevia
because of possible DNA mutation evidence reported by the European
Commission on Food Safety (also see the CSPI
report on Stevia).
Also see the CSPI report Foods
Additives to Avoid. The safest artificial sweetener seems
to be Spenda/Sucralose (see European
opinion). If you must use a sweetener, try a natural product
that has undergone minimal processing. The best natural sugar
appears to be Sucanet
(but it may be unsuitable for bread
making); also try using a small amount of honey (GI=58),
I use one teaspoon in a pot of peppermint tea.
- Avoid alcohol, tobacco,
and caffeine.
- Maximize your intake of
fish, chicken and turkey (without skin); mimimize your intake
of low-fat red meats.
- Always eat your minimum
daily protein requirement (about 0.4g/lb
of body weight, to a maximum of 100g/day).
If you have kidney disease you may be asked to limit your protein
intake, based on weight (0.25g/lb),
to about 20-60g/day; this recommendation
only seems to make sense, if you are already on dialysis, to reduce
the frequency of dialysis treatments. There are indications that
if you keep your blood glucose levels between 4-7mmol/L
(72-126mg/dL) that you needn't be
too concerned about how protein affects your kidneys. However,
there are also indications that you should keep your protein intake
below 100g/day because of its possible
effect on calcium loss. Determine your daily protein requirement
with the help of your doctor, nutritionist, or dietician (also
see item 2). Because of its effect on improving
your immune system, by boosting glutathione
production, try to incorporate at least 30g/day
of Whey Protein Isolate into your
daily diet.
- Use fats
rich in Omega 3-6-9 EFA (Essential
Fatty Acids) found in nuts, meats, fish, and dairy products. Use
cold-pressed unrefined vegetable oils; try Grapeseed and Flaxseed
oils. Use a balanced EFA supplement (at least 5g/day, about 1
teaspoon/day; I use 1 tablespoon/day of Udo's
Choice Ultimate Oil Blend).
- Choose a high-fiber
diet (whole-grain cereals, brown rice, bran, nuts, seeds,
beans, lentils, fresh fruit, and vegetables). You need to consume
about 25 to 35g of fiber/day (5-15g
soluble). You can get about 50% of your daily fiber at
breakfast time by eating 1/3-cup of Kellogg's All-Bran Buds.
- For snacks, consider selecting
foods from Rick Mendosa's Free
Food List.
- Eat as many fresh raw vegetables
as you want.
- Drink water all day. Sip
at least 8 glasses (64oz/2 litres)
every day.
What
to do next...
Review your proposed diet with
your doctor, nutritionist, and dietician; but remember, you are
the one in charge and you have to live with the consequences of
your choices and control your diet and blood glucose levels on a
daily basis.
