USDA EATING
PATTERNS
PATTERNS
This eating pattern translates dietary guidelines into recommended amounts from the major food groups.
What is the USDA Eating Pattern?
This enzyme in saliva begins the digestion of starch in the mouth.
What is salivary amylase?
These are the three energy-yielding macronutrients.
What are carbohydrate, fat, and protein?
These small blood vessels in the intestinal villi receive most water-soluble nutrients after absorption.
What are blood capillaries?
This process breaks food into smaller substances the body can use.
What is digestion?
At the 2,000-calorie level, the Healthy U.S.-Style Eating Pattern recommends this amount of fruit each day.
What is 2 cups per day?
This substance secreted by the stomach creates an acidic environment, denatures proteins, and activates pepsin.
What is hydrochloric acid or HCl?
Carbohydrate and protein each provide this many kilocalories per gram.
What is 4 kilocalories per gram?
These lymphatic vessels inside the intestinal villi receive most absorbed dietary fats.
What are lacteals?
This nutrient is primarily digested in the stomach.
What is protein?
At the 2,000-calorie level, the pattern recommends this amount of vegetables each day.
What is 2 and one-half cups per day?
This pancreatic enzyme digests most dietary fat in the small intestine.
What is pancreatic lipase?
This macronutrient provides 9 kilocalories per gram and is the most energy dense.
What is fat?
This blood vessel carries absorbed water-soluble nutrients from the digestive tract to the liver.
What is the hepatic portal vein?
These wave-like muscular contractions move food through the digestive tract.
What is peristalsis?
At the 2,000-calorie level, the pattern recommends this amount of dairy products each day.
What is 3 cups per day?
This pancreatic enzyme continues starch digestion in the small intestine.
What is pancreatic amylase?
Although protein can supply energy, this is its major role in the body.
What is building and repairing body tissues?
After transporting absorbed fats, the lymphatic system eventually empties its contents into this system.
What is the circulatory system or bloodstream?
These fingerlike projections and their microscopic extensions greatly increase the small intestine's absorptive surface.
What are villi and microvilli?
At the 2,000-calorie level, the pattern recommends this amount of protein foods each day.
What is 5 and one-half ounce-equivalents per day?
This enzyme breaks down the milk sugar lactose
What is lactase?
A food contains 10 grams each of carbohydrate, protein, and fat. It provides this many total kilocalories
What is 170 kilocalories?
This system transports absorbed nutrients to body cells and carries wastes away from them.
What is the circulatory system?
Digested nutrients enter the blood or lymph through this process.
What is absorption?
