Study Notes
Dietary Fiber
- Adequate Intake (AI) for dietary fiber is 38 grams for men and 25 grams for women.
Lactose Intolerance
- Yogurt is better tolerated than milk because the bacteria in yogurt breaks down lactose.
Hormones and Blood Glucose
- Glucagon raises blood glucose levels when they decrease between meals.
- Insulin works to lower blood glucose levels.
Health Risks
- Overweight individuals, like a 54-year-old woman with a 39-inch waist and sedentary lifestyle, are at high risk for type 2 diabetes.
Energy Sources
- When food hasn't been consumed for about 5 hours, the body uses glucose from liver glycogen to meet energy needs.
Carbohydrates and Sources
- Sugar alcohol includes xylitol.
- Carbohydrates include fructose, starch, and high fructose corn syrup.
- Foods can contain multiple types of carbohydrates.
- Rolled oats are likely the most significant source of fiber in a cereal bar.
Sugar Misconceptions
- The most common source of added sugars in the American diet is sweetened soft drinks.
- Sugar does not cause hyperactivity in children.
Fiber Characteristics
- Dietary fiber cannot be digested in the human digestive tract.
- Soluble fibers dissolve in water and form a gel, while insoluble fibers increase bulk and draw water into the large intestine.
Digestive Health
- Acute diverticulitis may require a low-fiber diet for healing.
- Disaccharides like sucrose must be broken down before absorption.
- The body absorbs carbohydrates in the form of monosaccharides.
Absorption Facts
- Glucose is absorbed primarily through the lining of the small intestine.
- It takes less than 8 hours for ingested carbohydrates to be fully processed in the body.
Food Labels and Sweeteners
- Non-nutritive, alternative sweeteners include sucralose and monk fruit, alongside regular sugar.
Additional Fiber Sources
- Nuts and seeds are good sources of dietary fiber along with whole grains.
Monosaccharides
- Fructose is a common monosaccharide.
Dietary Advantages
- A high-fiber diet can help normalize blood sugar levels.
Carbohydrate Metabolism
- After digestion, polysaccharides are converted into glucose in the liver.
Energy Intake Guidelines
- Recommended intake of carbohydrates should constitute 45-65% of total daily energy consumption.
Type 2 Diabetes
- Characterized by inadequate glucose levels in the bloodstream.
Saturated Fatty Acids
- Saturated fatty acids contribute to the solidity of fats like lard.
