Study Notes
Carbohydrates Overview
- Carbohydrates encompass starches, cellulose, and sugars, composed of carbon, hydrogen, and oxygen.
- Found in fruits, vegetables, legumes, grains, and dairy products, they can be categorized into simple and complex carbohydrates.
Carbohydrate Metabolism
- Enzymatic action in the mouth and small intestine converts carbohydrates into cellular energy.
- Main end products are glucose, galactose, and fructose, with glucose being the primary energy source for the brain and nervous system.
Disaccharides
- Formed by linking monosaccharides; examples include:
- Sucrose: composed of glucose and fructose
- Lactose: composed of glucose and galactose
- Maltose: composed of two glucose molecules
- Rapid disaccharide breakdown leads to blood glucose spikes within 10–15 minutes, posing risks for diabetics.
Complex Carbohydrates and Fiber
- Complex carbohydrates (polysaccharides) consist of long glucose chains, forming starch and fiber.
- Starch is digestible, while fiber, primarily plant cellulose, aids gastrointestinal health and protects against several diseases (e.g., colorectal cancer, diabetes).
Fiber Intake
- Recommended fiber intake varies, yet over 95% of Americans fall short.
- Increasing fiber intake should be gradual to avoid gastrointestinal discomfort, along with adequate hydration.
Ultraprocessed Foods (UPFs)
- Defined as foods not in their natural state, often containing high levels of sodium and fat, contributing to 50–60% of energy consumption in high-income countries.
- UPFs are lower in fiber and higher in sugar and salt due to refining processes, increasing disease risk (e.g., type 2 diabetes).
Carbohydrates and Disease Prevention
- Carbohydrate intake should constitute 50–65% of total caloric intake, focusing on whole grains, fruits, and vegetables rather than sugars and processed snacks.
- Plant-forward diets promote lower glycemic responses and are linked to reduced rates of chronic diseases.
Diets for Health
- Mediterranean and DASH diets are highlighted for their high fiber and complex carbohydrate content and associated health benefits, including lower risks of hypertension and cardiovascular diseases.
Carbohydrates for Athletes
- Athletes require carbohydrates for energy, using circulating glucose and stored glycogen during exercise.
- Carbohydrate loading maximizes energy reserves before competitions.
Lactose and Dairy
- Lactose, found in dairy, is a disaccharide requiring lactase for digestion, with a significant portion of the population experiencing lactose intolerance.
- Symptoms include bloating and gas, and lactose-intolerant individuals can often tolerate small amounts.
Blood Glucose Management
- Monitoring carbohydrate intake is crucial for blood glucose control; sugars cause rapid spikes, while starch and fiber have a milder effect.
- The glycemic index ranks foods based on their glucose impact, while glycemic load offers a more comprehensive assessment by accounting for serving size.
Nutritional Strategies
- Recommended strategies include focusing on self-management in diabetes care and choosing low-glycemic index foods for stable blood sugar levels.
