diabetes and eating
Source: National Institute of Diabetes and Digestive and Kidney
Diseases
Healthful eating helps keep your blood glucose, also called blood sugar, in
your target range. Physical activity and, if needed, diabetes medicines also
help. The diabetes target range is the blood glucose level suggested by diabetes
experts for good health. You can help prevent health problems by keeping your
blood glucose levels on target.
Blood Glucose Levels
What should my blood glucose levels be?
| Target Blood Glucose Levels
for People with Diabetes |
| Before meals |
90 to 130 |
| 1 to 2 hours after the start of a meal |
less than
180 |
Talk with your health care provider about your blood glucose
target levels and write them here:
| My Target Blood Glucose
Levels |
| Before meals |
______ to
______ |
| 1 to 2 hours after the start of a meal |
less than ______
|
Ask your doctor how often you should check your blood glucose on
your own. Also ask your doctor for an A1C test at least twice a
year. Your A1C number gives your average blood glucose for the past
3 months. The results from your blood glucose checks and your A1C
test will tell you whether your diabetes care plan is working.
How can I keep my blood glucose levels on target?
You can keep your blood glucose levels on target by
- making wise food choices
- being physically active
- taking medicines if needed
For people taking certain diabetes medicines, following a
schedule for meals, snacks, and physical activity is best. However,
some diabetes medicines allow for more flexibility. You’ll work with
your health care team to create a diabetes plan that’s best for
you.

Talk with your doctor or diabetes teacher about how many meals
and snacks to eat each day. Fill in the times for your meals and
snacks on these clocks.

Your Diabetes Medicines
What you eat and when you eat affect how your diabetes medicines
work. Talk with your doctor or diabetes teacher about when to take
your diabetes medicines. Fill in the names of your diabetes
medicines, when to take them, and how much to take. Draw hands on
the clocks to show when to take your medicines.

Your Physical Activity Plan
What you eat and when also depend on how much you exercise.
Physical activity is an important part of staying healthy and
controlling your blood glucose. Keep these points in mind:
-
Talk with your doctor about what types of exercise are safe for
you.
-
Make sure your shoes fit well and your socks stay clean and
dry. Check your feet for redness or sores after exercising. Call
your doctor if you have sores that do not heal.
-
Warm up and stretch for 5 to 10 minutes before you exercise.
Then cool down for several minutes after you exercise. For
example, walk slowly at first, stretch, and then walk faster.
Finish up by walking slowly again.
-
Ask your doctor whether you should exercise if your blood
glucose level is high.
-
Ask your doctor whether you should have a snack before you
exercise.
-
Know the signs of low blood glucose, also called hypoglycemia.
Always carry food or glucose tablets to treat low blood
glucose.
-
Always wear your medical identification or other ID.
-
Find an exercise buddy. Many people find they are more likely
to do something active if a friend joins them.
Low Blood Glucose (Hypoglycemia)
Low blood glucose can make you feel shaky, weak, confused,
irritable, hungry, or tired. You may sweat a lot or get a headache.
If you have these symptoms, check your blood glucose. If it is below
70, have one of the following right away:
- 3 or 4 glucose tablets
- 1 serving of glucose gel—the amount equal to 15 grams of
carbohydrate
- 1/2 cup (4 ounces) of any fruit juice
- 1/2 cup (4 ounces) of a regular (not diet)
soft drink
- 1 cup (8 ounces) of milk
- 5 or 6 pieces of hard candy
- 1 tablespoon of sugar or honey
After 15 minutes, check your blood glucose again. If it’s still
too low, have another serving. Repeat these steps until your blood
glucose level is 70 or higher. If it will be an hour or more before
your next meal, have a snack as well.

The Food Pyramid

The food pyramid can help you make wise food choices. It divides
foods into groups, based on what they contain. Eat more from the
groups at the bottom of the pyramid, and less from the groups at the
top. Foods from the starches, fruits, vegetables, and milk groups
are highest in carbohydrate. They affect your blood glucose levels
the most.
How much should I eat each day?

are a
- small woman who exercises
- small or medium-sized woman who wants to lose weight
- medium-sized woman who does not exercise much

When You’re Sick
Take care of yourself when you’re sick. Being sick can make your
blood glucose go too high. Tips on what to do include the
following:
-
Check your blood glucose level every 4 hours. Write down the
results.
-
Keep taking your diabetes medicines. You need them even if you
can’t keep food down.
-
Drink at least one cup (8 ounces) of water or other
calorie-free, caffeine-free liquid every hour while you’re
awake.
-
If you can’t eat your usual food, try drinking juice or eating
crackers, popsicles, or soup.
-
If you can’t eat at all, drink clear liquids such as ginger
ale. Eat or drink something with sugar in it if you have trouble
keeping food down, because you still need calories. If you can’t
eat enough, you increase your risk of low blood glucose, also
called hypoglycemia.
-
In people with type 1 diabetes, when blood glucose is high, the
body produces ketones. Ketones can make you sick. Test your urine
or blood for ketones if
- your blood glucose is above 240
- you can’t keep food or liquids down
-
Call your health care provider right away if
- your blood glucose has been above 240 for longer than a day
- you have ketones
- you feel sleepier than usual
- you have trouble breathing
- you can’t think clearly
- you throw up more than once
- you’ve had diarrhea for more than 6 hours
