Nutrient Density |
The nutrient content for the amount of calories consumed - For example, an apple will have higher nutrient content than an apple pie, and a baked potato will have higher than fries |
|
|
Factors Affecting Food Choice |
1) Taste, smell, appearance, texture 2) Emotional attachment to certain foods 3) Cultural and societal norms 4) Geographic availability 5) Environment 6) Health Consciousness 7) Psychological states 8) Price, convenience accessibility 9) Social influences |
|
|
6 Essential Nutrients |
Water, carbohydrates, lipids, proteins are MACROnutrients <- energy yielding Vitamins and Minerals are MICROnutrients 1) Water 2) Carbohydrate (sugars, starches, fibers) 3) Lipids (cholesterol, saturated fats, unsaturated fats) 4) Proteins (made of amino acids) 5) Vitamins (fat and water soluble) 6) Minerals (chemical elements) |
|
|
Neutraceutical/Designer Food |
Foods that are fortified with nutrients or enhanced with phytochemicals - Have added health benefits beyond basic nutrition Ex. Vitamin Water, Omega-3 eggs |
|
|
Energy |
What is used for body processes and physical activity - Necessary for cellular respiration - Measured in kilocalories (kcal) = 1000 calories = 1 Calorie 1) Fat (9kcal/g) 2) Carbohydrate (4kcal/g) 3) Protein (4kcal/g) 4) Alcohol (7kcal/g) <- not a nutrient |
|
|
Nutrient |
1) Provides energy 2) Body structure regulation (fats, carbs, proteins, minerals, water, NOT vitamins) 3) Body process regulation (all nutrients) |
|
|
Phytochemicals |
Any of various biologically active compounds found in plants - May have benefits beyond basic nutrition > Could be functional foods |
|
|
Undernutrition |
When intake doesn't meet needs - More common in developing countries Ex, inadequate water leads to dehydration |
|
|
Overnutrition |
When intake exceeds body needs - More common in developed countries Ex, excess calories promotes obesity |
|
|
Nutrient Epigenetics |
A field that focuses on how nutritional factors, mostly prenatal and early life can affect how DNA is expressed - Doesn't change the genes but can affect whether certain genes are turned on/off - Can potentially increase risk for disease |
|
|
Healthy Diet |
1) Eat a variety of foods - eat foods from different groups 2) Practice moderation - not too much or too little 3) Balance your choices - balance healthy and unhealthy, nutrients, energy in and out |
|
|
Scientific Method |
Begins typically with a hypothesis and specific methods are used to test this hypothesis - Hypothesis is tested by observing - Results are gathered, analyzed, and conclusions are drawn based on findings |
|
|
Blind Study |
Research subjects do not know if they are in the experimental group or control group |
|
|
Double Blind Study |
Both researchers and subjects do not know whether test subjects are in control or experimental group |
|
|
Peer-Review |
Process that scientists undergo to submit studies for publication helps ensure that studies have been properly conducted and that results have been properly analyzed |
