NDS 370 EXAM #2 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
How added sugars can contribute to health problems - Answers The dietary guidelines caution that
added sugars may increase the risk of certain diseases, even in the absences of overweight or obese.
Identify the health benefits and recommendations of starches and fibers - Answers Help lower
cholesterol
Prevents diabetes by lowering blood glucose
Prevents cardiovascular diseases
Help maintain lower weight
Summarize the key scientific evidence behind some of the current controversies surrounding
carbohydrates and their kcalories. - Answers Overeating is the cause not the proportion of the energy
nutrients in the diet. Any diet can produce weight loss at least temporarily if energy intake is
restricted.
Monosaccharides, Disaccharides, and Polysaccharides common nutrition by their chemical structures
and major food sources - Answers Monosaccharides: Single sugars
Disaccharides: Sugars composed of pairs of monosaccharides
Polysaccharides: Large molecules composed of chains of monosaccharides.
Carbohydrate digestion & absorption - Answers carbohydrates digestion decreases in the stomach,
the small intestine does most of the work for digestion.
recognize the chemistry of fatty acids and triglycerides and the differences between saturated and
unsaturated - Answers Provides cells with energy (virtually unlimited ability to store fat energy). Must
be supplied by Liolenic & Linolenic acids.
Triglycerides - Answers are composed when one glycerol chain and 3 fatty acids chains covalently
bond through dehydration by removing the water molecules .
linoleic acid - Answers linoleic acid is a polyunsaturated essential fatty acidthat is found mostly in
plant oils. It's known as the parent fatty acid of the omega-6 series, and it is essential for human
nutrition because it cannot be synthesized by the human body.
Chemistry, food sources, and roles of phospholipids - Answers Phospholipids: A compound similar to
triglycerides but having phosphate group. Used in natural foods, the richest foods are liver, eggs, and
soybeans. ROLES: Constituents of cell membrane. They help fat-soluble substances, including
vitamins, hormones to pass in and out of cell.
Chemistry of Sterols - Answers Compounds containing 4-ring carbon structures with any variety of
side chains attached, the most well known sterol is cholesterol. Used in plants and animals. Only from
animals contain significant amounts of cholesterol-meats, eggs, seafood, poultry, and dairy products.
ROLES: Vitally important body compounds are sterols. Among them are Bile acids, the sex hormone,
the adrenal hormones.
linolec acid - Answers linoleic acid contains two double bonds with cis configuration
Fat digestion, absorption and transport - Answers In the stomach fat is separated from other food
substances. In the small intestine, bile emulsifies fats while enzyme digest them. The intestinal cells
absorb the fats. Long-chin fatty acids from large lipoprotein called Chylomicron that transports fats
through the lymph system.
Outline the major roles of fats in the body, including a discussion of essential fatty acids and the
omega fatty acids. - Answers the bodies triglycerides provide energy, insulate against body
temperature extremes, protect against shock, provide structural material for cell membranes and
participate in cell signaling pathways .
Relationships between saturated, trans, and cholesterol and chronic diseases - Answers High blood
cholesterol, heart diseases, cancer & obesity. Recommendations: None RDA or upper level has been
set/. DRI suggest that 20-35% of daily energy intake from fat, less than 10% of daily intake from
saturated fats, and little of trans and cholesterol.
Relationships between monounsaturated and polyunsaturated fats and health - Answers healthy
types of fats, Monounsaturated fats have only one unsaturated carbon bond. Polyunsaturated fats
are also known as omega-3-omega 6 with more than one double bond in the fatty acid.
