preparation, ripeness, and other foods eaten at the same time lower, higher up gastroparesis
-Glycemic Index Can Change That number is a starting point on paper. It could be different on your plate, depending on several things. Such as ____ Preparation. Fat, fiber, and acid (such as lemon juice or vinegar) _____ the glycemic index. The longer you cook starches like pasta, the ____ their glycemic index will be. Ripeness. The glycemic index of fruits like bananas goes ____ as they ripen. Other foods eaten at the same time. Bring down the overall glycemic index of a meal by combining a high-glycemic index food with foods that have lower ones. Your age, how active you are, and how fast you digest food also affect how your body reacts to carbs. If you have a diabetes complication called ___, which delays your stomach from emptying, your body will absorb food much more slowly. TO SIMPLIFY For a diet with a lower glycemic load, eat: More whole grains, nuts, legumes, fruits, vegetables without starch, and other foods with a low glycemic index Fewer foods with a high glycemic index, like potatoes, white rice, and white bread Less of sugary foods, including candy, cookies, cakes, and sweet drinks You can still eat foods with a high glycemic index. Just enjoy them in smaller portions, and offset them with nutritious, low-glycemic index foods when you do.
insulin, blood sugar smaller 55 56-69 70 or higher
-The higher the GI- the more demand for ____ and less control of blood sugar- thus diabetics will do better with low GI foods. The ____ the number, the less impact the food has on your blood sugar. ____ or less = Low (good) 56- 69 = Medium ____ or higher = High (bad) Look for the glycemic index on the labels of packaged foods. You can also find glycemic index lists for common foods on the Internet.
milk allergy
A ____ occurs when the immune system doesn't recognize one or more of the proteins in milk as being harmless, and reacts against them. The two main proteins in milk that are known to cause reactions are casein and whey. Casein and whey are also found in many processed foods. Infants are at a higher risk of suffering from a milk allergy, with around 2-3% of the world's population being affected. Although symptoms can be serious, the good news is that most children outgrow a milk allergy by age two or three.
immune digestive, lactase
A milk allergy is often confused with lactose intolerance because some symptoms are similar. But the two conditions are very different. A milk allergy is a reaction by the ___ system, but lactose intolerance affects the digestive system when there's an inadequate supply of the ____ enzyme to break down lactose.

Although they're actually made from hundreds—or even thousands—of simple sugars linked together, they react quite differently inside your body. After you ingest a complex carbohydrate (or starch), several enzymes break it down into its simplest form, called ____. Glucose is the simple sugar that your body recognizes and absorbs. All types of carbohydrate (simple and complex) must be broken down and converted into glucose before your body can absorb and use it for ____

In general, fiber supplements may reduce or ___ your body's absorption of certain medications. Try to take medications at least 1 hour before or 2 to 4 hours after taking a fiber supplement. You should always drink an 8 oz. glass of water with fiber supplements. It is also important to drink at least 6 to 8 full glasses of water throughout the day to avoid ___. -They come in many forms, from capsules to powders to chewable tablets. They contain what's called "functional fiber," which may be extracted from natural sources or made in a lab. Extracted natural fibers include ____ (a compound found in plant cells), ____ (a sugar found in plant cells), ____ (a sugar found in fruits and berries), ____ (a sugar found in seeds), and ____ ( from the husk of Plantago plants, its the only supplemental fiber shown to help lower LDL "bad" cholesterol). Common manufactured fibers include polydextrose and polyols, and maltodextrins. Diabetes medications: Fiber supplements may help regulate blood sugar levels. But they can also reduce the absorption of some medications, such as ____ (Diabetes) and ____ (Glucophage). Talk to your doctor before taking fiber supplements if you have diabetes. DO NOT take fiber supplements at the same time as your medications. Wait a few hours in between. Cholesterol-lowering medications: Combining _____ or other soluble fibers with cholesterol-lowering medications (known as bile acid sequestrants) may help lower cholesterol levels. If you take these medications, talk to your doctor to see whether psyllium is safe and right for you. These drugs include: Cholestyramine (Questran) Colestipol (Colestid) One study found that when people taking simvastatin (Zocor) added psyllium supplements to their regimen, they lowered cholesterol levels as much as if they had been taking a double dose of simvastatin. Digoxin: Fiber supplements may reduce the body's ability to absorb digoxin (Lanoxin), a medication used to _____. DO NOT take fiber supplements at the same time as digoxin. Lithium: Clinical reports suggest that ___ or other soluble fibers may lower lithium levels in the blood, making lithium less effective. Lithium levels should be monitored very closely by a doctor, especially if there is a big change in fiber intake. Natural sources of fiber usually will not cause the type of distress that Dawson is experiencing here by the creek. It looks like he had too much fiber and not enough water. If you eat a variety of the whole foods (fiber sources) you will also be getting some water within those foods.

What's up with fruit?- -fruits and fruit juices contain ____ (a natural simple sugar) and provide several vitamins and minerals. -Eating fresh fruit or drinking 100 percent fruit juice is far from pumping "empty calories" into your system. When you can, choose whole fruit over fruit juice: you get the same nutrients, as well as more ___ ___ and ___.
Lactose intolerance
___ ___ is the inability to digest a sugar called lactose that's found mainly in milk and dairy products. Normally, the small intestine produces an enzyme called lactase, which breaks down lactose into two simple sugars, glucose and galactose, which can be absorbed into the bloodstream. People whose bodies don't make enough lactase can't fully digest lactose, causing mild to uncomfortable side effects. WHAT options do these people have? Lactaid (enzyme)- take prior to consuming dairy Lactaid milk, ice cream ,etc.. It is REAL cow's milk but they have added in the enzyme and broken down the lactose ahead of time Almond milk, rice milk, soy milk, etc.. Pros and cons with each of these

soluble
____ fiber pulls in water to form a gel in the digestive tract. This slows digestion, so your stomach and intestine do not absorb as much of some nutrients, like starch and sugar. As a result, cholesterol levels go down over time, which may help prevent heart disease and stroke. Consuming soluble fiber may also improve glucose tolerance in people with diabetes.
