Type 1 Diabetes Fiber

Type 1 diabetes places you at increased risk for heart disease and stroke. A diet that is higher in can lower cholesterol levels, lessening your risk for heart disease. If you also have high blood pressure, fiber may be even more practical. Some studies have shown that people with hypertension who increase fiber in the diet for at least 8 weeks can significantly lower their blood pressure. You must keep up with the high fiber diet or the positive effect on blood pressure will go away.

Dietary fiber (particularly soluble fiber) can slow the body's absorption of sugars and help people with diabetes manage their blood sugar levels.

High Fiber Diet
Dietary fiber is a plant material that humans cannot digest. Fiber increases the amount of stool in your intestine. The most well known fiber is bran.

Fiber comes in two forms, based on whether it will dissolve in water: soluble and insoluble fiber. Most experts believe that about 3/4 of fiber intake should be insoluble.

Common fiber supplements include Citrucel and Metamucil. Regular use of these high-fiber products is safe. They are also more effective when used regularly. Drink plenty of water when taking extra fiber.

Water Soluble Fiber

ExamplesDietary Sources
Pectins, gums, & mucilagesfruits, vegetables, oats, bran, barley, legumes

Insoluble Fiber
ExamplesDietary Sources
Cellulose, hemicellulosevegetables, wheat bran, & whole grains

Fiber tends to bind water, which leads to softer stools and a more rapid passage of material through the intestines. This rapid transit may reduce the exposure of the bowel to toxic substances and improve overall bowel health. Fiber can also bind fats and cholesterol. As an added benefit, high fiber foods usually contain important vitamins and minerals.

Use of a High Fiber Diet
Most people in developed countries do not eat enough fiber. A healthy diet should include more than 25 grams of fiber each day, or 10-13 grams per 1,000 calories. Some experts believe that every extra gram of fiber eaten each day can lower the risk of heart disease by as much as five percent.

This diet is often recommended for preventing or treating the following:

General Guidelines
In general, fruits, vegetables and whole grains are high in fiber. Check food labels of prepared products to see if there are at least 3 grams of dietary fiber per serving. Look for the term 'whole grain' as a major part of the food.

Raw foods tend to have more fiber than cooked, canned or pureed items. Even chopping and peeling skins removes some fiber. Dried fruits are especially high in fiber. Beans, black-eyed peas, brans and oatmeal are very high in fiber.

Unprocessed wheat bran can be added to many home meals and most baked foods. Bran is the outer layer of the wheat grain, and is present in 'whole grain' foods. Adding 2-3 teaspoons of bran per serving is a great way to increase the fiber content of casseroles, meat loaf, and baked goods. Whole grain flour has 6 times the fiber of standard, bleached flour. Oat bran can be used in place of about 1/3 of regular flour when baking.

Try adding nuts or bran to dairy foods such as yogurt or cottage cheese, which normally have very little fiber. Avoid white bread and flour pasta.

Change your diet slowly and drink plenty of fluids to allow the fiber to do its work. Rapid changes in the diet can cause bloating, gas and diarrhea. A varied, high-fiber diet is much better than taking fiber supplements.

Example High-Fiber Diet
Breads and Grains
Eat at least 3, and as many as 10 servings each day of various whole grain foods. Any grain food should say 'whole grain' and contain at least 3 grams of fiber per serving.

Examples include:
  • Barley
  • Brown rice
  • Oatmeal or oat bran
  • Rye bread
  • Wheat germ
  • Whole grain bagels
  • Whole grain breads
  • Whole grain muffins
  • Whole grain or bran cereals
  • Whole grain pita bread
  • Whole wheat crackers
  • Whole wheat pasta

Fruit:
Eat at least 3-4 servings each day. All fruits are good, and dried fruits are especially high in fiber.

Examples include:
  • Apple
  • Banana
  • Berries
  • Grapefruit
  • Nectarine
  • Orange
  • Peach
  • Pear

Vegetables:
Eat at least 3-5 servings per day, preferably raw and unpeeled

Examples include:
  • Asparagus
  • Broccoli
  • Cabbage
  • Carrots
  • Green beans
  • Green pepper
  • Onions
  • Peas
  • Potatoes with skin
  • Snow peas
  • Spinach
  • Squash
  • Sweet potatoes
  • Tomatoes
  • Zucchini

Meat substitutes:
Meat has no fiber and contains various amounts of cholesterol and saturated fats. There are many high-fiber foods that can partially or completely replace meat in the diet. Using several servings of meat substitutes each day will greatly increase total fiber intake.

Examples include:
  • Almonds
  • Brazil nuts
  • Cashews
  • Garbanzo beans
  • Kidney beans
  • Lentils
  • Lima beans
  • Peanut butter
  • Peanuts
  • Pinto beans
  • Sesame seeds
  • Soybeans, but not tofu
  • Split peas
  • Sunflower seeds
  • Veggie burgers
  • Walnuts

Snacks:
  • Bean dip
  • Cookies made with oatmeal, whole wheat flour, fruit and nuts
  • Popcorn
  • Tortilla corn chips (baked)
  • Trail mix
  • Whole wheat pretzels
