Causes hypertension
Nutrient density
Choose foods high in nutrient density and low in energy density. Avoid foods low in nutrient density and high in energy density. Goal: Get the most nutrients for the fewest calories.
Additional nutrients in vegetables
Complex CHO = less impact on blood sugar levels than fruit. -Starchy vegetables have higher total carbohydrates -Non-starchy vegetables have lower total carbohydrates -fruits have simple sugars while CHO have complex CHO Vitamin K = promotes blood clotting and a component of healthy bone. Vitamin E = immune function & fat soluble antioxidant Magnesium = important for nerve function and helps with bone strength
What are the main macronutrients that are provided by the grain group?
Complex CHO = less impact on blood sugar levels than sugar containing foods. Insoluble Fiber = helps with regular fecal movement which is associated with lower colon cancer risk.
Moderation
Consuming "enough" but not too much or too little of a food. Allows for "unhealthy" food choices in small amounts. Also includes moderation of alcohol.
Kcal Control
Consuming a calorie intake in proportion to calorie expenditure. Use EER to evaluate energy balance.
What are the daily values and how are they used?
Daily Values (DV) are given for many of the nutrients on the food label based on a 2000 kcal diet. DV reference standard is based on 1968 RDAs The DV on the food label is shown as a percentage of recommended intake (% Daily Value): -% DV = Nutrient Amount / DV Recommendation * 100 -% DV = 300 mg Calcium / 1000 mg Calcium * 100 -% DV = 30% Purpose of DV is to determine whether the person has: -Enough of the essential nutrients = > 100 % DV -No excesses (> 100% DV) for potentially unhealthful nutrients

What are phytochemicals and where are they found?
Naturally occurring plant chemicals such as pigments that enhance health. Work together in whole foods in a unique way to provide health benefits. Found in soy, garlic, onions, teas, coffee. Scientific study of phytochemicals is new. May reduce risks for chronic diseases (cancer and cardiovascular disease).
What the three different claims manufactures can put on their labels
Nutrient Content Claims Health Claims Structure Function Claims
Too much grain leads to
Obesity and diabetes
Whole grain vs processed grains vs enriched
Processes grains lose the nutrients from the whole grains. Enriched grains try to resupplement processed grains but does not reach original amount.
Which macronutrients can be found in milk and milk products
Protein, fat and CHO.
Adequacy
Providing "enough" of the essential nutrients to maintain health. Use EAR, RDA, & AI to determine adequacy. If not adequate, then a state of under-nutrition or deficiency.
Balance
Providing food groups/nutrients in proportion to one another and in proportion to the body's needs. Use AMDR to evaluate macronutrient balance.
What is the basic difference between a whole grain and a refined grain
Refined grain loses much of the nutrients found in whole grain. Whole grain has a gritty taste while refined grain gets rid of the gritty tste
Why is juicing fruits bad?
Removing the fiber If I take a whole fruit that has fiber, if I put the piece of fruit in a blender then it gets rid of the structure If I take an ogange and blend it, the fiber is broken apart then I have concentrated sugar water
What is the nutrient content claim
Statements that characterize the quantity of a nutrient in a food. Fat-free and cholesterol free Good source of fiber High in calcium Often relate to vitamins, minerals, fat, cholesterol, sodium, fiber, and sugar. Specific guidelines set by FDA must be met in order to use on food label.
Structure function claims
Statements that characterize the relationship between a nutrient or other substance in food and a disease or health-related condition. FDA holds manufacturers to a higher standard of scientific evidence prior to allowing health claims on labels. Some argue the newer FDA system used to categorize health claims is more liberal & manufacturer friendly than in the past.
