Society, trends, culture, convenience, emotions and cost, to name a few.
|
What is DRI (Daily Recommended Intake)?
The acronym that takes into account other acronyms, including EAR, RDA, AI and UL, and helps determine the right amount of each nutrient we should consume.
|
What is mechanical digestion?
The type of digestion that includes the chewing, grinding and breaking food into smaller pieces.
|
What is glucose?
The sole energy source for brain cells and red blood cells, it is the primary sugar in carbohydrate-rich foods.
|
What is saccharin?
The oldest sugar substitute (or sweetener), is 200% - 700% sweeter than table sugar (sucrose).
|
What are heart disease, cancer, stroke and diabetes?
Four of the top ten leading causes of death that are influenced by nutrition and lifestyle.
|
What are the Dietary Guidelines for Americans?
Different than DRIs, these are based on the most current nutrition and physical acvitiy research, are updated every 5 years, and are designed to help individuals prevent chronic disease.
|
What is the small intestine?
It includes the duodenum, jejunum and ileum and accounts for most of the digestion of foods we consume.
|
What is lactose? And what are galactose and glucose?
Different from fructose (glucose + sucrose) and maltose (glucose + glucose), this sugar is needs lactase to be digested and is made of these two monosaccharides.
|
What are ketones (or ketone bodies)?
These compounds are produced by the body in the absence of sugar, when protein is broken down for energy.
|
What are macronutrients?
Unlike micronutrients, the body needs these nutrients in much larger quantities; they include fats, carbohydrates and proteins
|
What are discretionary calories?
These are the calories that can be consumed beyond those needed to fulfill nutrient needs but still be within the calorie allowancce necessary to maintain a healthy body weight.
|
What are villi and microvilli?
The thousands of finger-like projections covering the wall of the small intestine that increase the surface area for nutrient absorption.
|
What is insulin?
This hormone, secreted by the pancreas, acts to "open the doors" on muscle and fat cells to let glucose in.
|
What is type 1 diabetes?
This autoimmune disease is the result of destruction of insulin-producing beta cells of the pancreas.
|
What is calcium?
Americans generally fall short of the dietary recommendations of iron, vitamins D and E, potassium and this bone-building mineral.
|
What are 45% - 65%, 10% - 30%, and 20% - 35%?
Respectively, the macronutrient distribution ranges for carbohydrates, protein and fat.
|
What are digestive enzymes?
The substances that are produced mostly by the pancreas (including those responsible for a majority of fat digestions, and about half of protein and half of carbohyrate digestion).
|
What is glycogen? And what is glucagon?
This storage form of carbohydrates is broken down into glucose when this hormone is released by the pancreas.
|
What is 130 grams?
The minimum amount of carbohydrate needed daily.
|
What are nutrient-dense foods?
These foods, which are part of a healthy diet, contain many vitamins, minerals and other nutrients compared to the calories they contain.
|
What is a healthy claim?
Often found on food packaging, this claim must contain a food compound and a health condition related to that claim. Think Quaker.
|
What is celiac disease?
An autoimmune disorder resulting in damage to the small intestine as a result of gluten consumption.
|
What are soluble and insoluble fibers?
These two forms of carbohydrate help reduce the risk o some cancers, heart diseae, diabetes and obesity.
|
What is the mouth? And what is salivary amylase?
Mechanical and chemical digestion begin here. This enzyme is responsible for the first steps of carbohydrate breakdown.
