Cholesterol is non-essential because our body makes it and we don’t need to get it *All of the above are needed to: 1.Convert carbs, fat, and proteins into usable energy and 2.for building and maintaining muscles, blood components, bones, etc. Categories Defined Energy Provided  Provide 0 calories Phytochemicals: plants with Ex: Beta- Nutrient color. carotene considered to be  Flavor  Makes non-essential.  Protects carrots Most commonly plants from orange. known as the insects and  Red bell pigmentation of disease. peppers food. have more vitamin C than an orange.  Green foods contain chlorophyll so it overpowers other colors. 2 Anti-oxidants: Chemical 0 calories Some can be substances that essential like prevent or repair vitamins or damage caused minerals but to cells caused we do not need by: some of them  Ozone layer to survive so  Oxygen: some are non- Oxidation essential. (damage that is caused by the tissues or cells in the body)  Pollution  Smoke *Both above protect the plant and human cells from damage that can make them susceptible to disease.  Ex: Sulfur containing phytochemicals  Helps prevent certain cancers o Brussel Sprouts: strongest sulfur containing phytochemical. Prevents cancers and protects genetic materials. Eating Brussel sprouts 3-4 times a week can reduce the risk of cancer by 40%. Some related terms to know: 3  Free Radicals: Free lone molecules hanging out and don’t like being alone so they latch onto everything they see. o Ex: cells, tissues  Reduce Oxidation: anti-oxidants (provides free radicals something to stick onto) Essential VS. Non-Essential  Essential o The body requires this nutrient but is unable to manufacture them. o Acquired through diet o 9 essential amino acids, the rest are considered non-essential.  Non-essential o The body does not require these nutrients from the diet (although they may still be found in foods) o Either produces them or the body makes them o Does not require them in order to survive Essential Nutrients  Vitamins o Biotin o Folate o Niacin o Pantothenic acid o Riboflavin o Thiamine o B6 o B12 4 o Vitamin C, A, D, E, K (Vitamin K found in leafy greens and vegetables. 50% of Vitamin K is made in our gut.)  Minerals o Calcium o Chloride o Chromium o Copper o Fluoride o Iodine o Iron o Magnesium o Manganese o Molybdenum o Phosphorus o Potassium o Selenium o Sodium o Zinc *Don’t have to memorize above for the exam. Just be familiar with some of them. Other Essential Nutrients  Omega 3  Omega 6  Certain amino acids (9) Non-Essential Nutrients  Cholesterol  Certain amino acids  Phytochemicals 5 Requirements  Varies from person to person and day by day  Based on: o Age: as we age we require less amount of calories but more vitamins and minerals. o Gender: Females contain more body fat because of excess fat cells in their hip region for the purpose of childbirth. Men have more muscle tissues/cells. o Growth status: Growing children require more calories and more vitamins and minerals. o Body size: can depend on genetics; bone density. o Genetic traits: born with different amounts of fat cells.  In addition to certain conditions o Pregnancy: When pregnant they are creating more tissues/cells. Need 100 more calories than already eating. o Breastfeeding: Need 500-700 calories more than already eating to replenish the body. o Illness: best thing to do is increase calories, vitamins, and minerals. o Drug use: illegal drugs: increase calories… legal (prescription) drugs: decrease or prevent calories o Exposure to environmental contaminate: smoke: eat more anti-oxidants *Above requirements will be on the exam, especially the highlighted region. 6 RDA VS. DRI  RDA defined (recommended dietary allowances): o The minimal amount required for survival  DRI defined (dietary reference intake): o Requirements to help you achieve optimal health Introduction  Growth and health takes place within the cell and the fluid surrounding them.  Body consists over one hundred trillion cells.  Functions are maintained by the nutrients it receives.  Problems arise when a cell’s need for nutrients differs from the available supply. Cells  Building blocks of: o Tissues  Muscles  Bones o Organs  Kidney  Heart  Liver o Systems  Reproductive  Respiratory  Circulatory  Nervous System o Cells need to live in a “utopia” 7  If deficient or toxic levels:  Organ failure  Cells produce proteins in abnormal forms Nutrition Concepts #4  Poor nutrition can result from both inadequate and excessive levels of nutrient intake. Introduction  For every nutrient there is a range of optimal intake for optimal cell functioning.  Either side of the range is associated with: o Behavioral/ cognitive disabilities o Physical  Example: Vitamin C: wounds/healing o Low intake of Vitamin C results in bleeding gums (scurvy)  Scurvy -> bleeding gums, pain upon being touched, impaired bone growth. o Marginal/ Mild Deficiency  Delayed wound healing o Excessive/ High intake of Vitamin C results in diarrhea.  Diarrhea Deficiencies Everything Starts in the Cells (Know all Steps)  Step 1: o Inadequate dietary intake  Ex: prolonged deficient vitamin A intake  Step 2: 8 o Depletion of tissue reserves of the nutrient  Ex: reduced liver stores of vitamin A  Step 3: o Decreased blood levels of the nutrient  Ex: reduced blood levels of vitamin A  Step 4: o Decreased nutrient available to cells  Ex: decreased vitamin A available to cells within eye  Step 5: o Impaired cellular functions  Ex: impaired ability to see in dim light (night time).  (irreversible, but if caught early can prevent further damage)  Step 6: o Physical signs and symptoms of deficiency  Ex: outer covering of the eyes dries out, thickens, and becomes susceptible to infection  Step 7: o Long-term impairment of health  Ex: outer covering of the eyes dries out and thickens; vision is lost 9
