HL-04 Balanced Activity and Nutrition Instructor Janne Maier, M.S. 03-08-2016 Let’s Move • I think we have confirmed that moving increases our heart rates • We’ll circle the building What is Nutrition? • Conventional concept – “The process of nourishing or being nourished, especially the process by which a living organism assimilates food and uses it for growth and for replacement of tissues” • WHO definition – “Nutrition is the intake of food, considered in relation to the body’s dietary needs.” Defining “Dietary Needs” • No two people are the same • Aspects that effect nutritional needs include – Age and gender, potential medications – Digestive system and genetics – How active you are • Both activity level and type influence “need” – Affects both calorie need and specific requirements – Bodybuilder vs marathon runner Basic Nutrition • Macro nutrients and micro nutrients – Sources and balance – Changing needs with age • How to get at nutrients – Digestive system Good Nutrition • Good nutrition can help prevent disease and promote health. There are six categories of nutrients that the body needs to acquire from food: – – – – – – Protein, Carbohydrates Fibers Fat Vitamins, minerals Water Essential Nutrients • Nutrients required for the body to function that we can’t produce ourselves, or that we can not synthesize in adequate amounts – All groups on previous slide have essential as well as non essential • Non-essential we can make as long as supply of essentials is met – Water is “essential” because we need lots, but can’t produce it ourselves Macro Nutrients • Carbohydrates – Recommended intake: 45-65% daily calorie intake – 4 calories per gram • Fats – Recommended intake: 10-35% daily calorie intake – 9 calories per gram • Protein – Recommended intake: 10-35% daily calorie intake – 4 calories per gram Carbohydrates • Types of carbs and their function – Sugar: simple = 2 or complex = 3 or more • Fiber- indigestible so not technically a nutrient – Soluble fiber; dissolves in water, becomes gelatinous – Insoluble fiber; does not dissolve • Oats vs celery ! • Most fibers ferment in the lower GI tract – Changes the way other nutrients are absorbed – Retains water in the stool and produces gas Carb Sources • Fruit and vegetables – To cook, lightly steam, bake, or sauté – Eat raw to retain enzymes and full nutrient profile • Grain products – Whole grain provides more fiber • Seeds, legumes, nuts, etc., lots of fiber – Most contain both carbs fat and protein • Dairy, no fiber here ! – Milk, yogurt, cheese – Pick products naturally low in fat Range of Motion Pick Your Poison And some leg stretches Fats • Types of fat • Saturated, solid at room temperature – Less than 10% of daily calories from here • Mono and poly unsaturated, liquid at room temp – Two kinds of poly: omega 3 and 6 • Trans or hydrogenated fat- can it be avoided Fat Sources • Saturated fat – Meat, dairy, tropical oils e.g.. coconut and palm oil • Unsaturated fat – Mono: avocado, nuts, some vegetable oils e.g. olive – Poly: sunflower or sesame oil, seafood – Omega 3 from plants and seafood, 6 from plants • Trans fat – Processed market foods with long shelf lives Protein • Building blocks of tissue – Source of amino acids – 9 are essential, others we can synthesize (more or less) – Can be a source of energy Protein Sources • Complete protein from meat dairy and fish – Provides all amino acids, essential and non essential • Other sources are nuts, seeds, grain – Contain a variety of amino acids – A well researched vegan diet can provide all essential amino acids • Interesting trivia about protein sources per person: – World wide protein source 60% from plants – US protein source 70% from animals Macro Nutrient Balance • Most protein intake constant even trough dietary changes • Fat and carbohydrates tend to titer – High carb intake associated with high fiber – High fat intake associated with high calorie intake • BEWARE ! – Fat, whether from nuts (full of nutrition) or from trans-fat (no nutrition), contains the greatest amount of calories per gram of any food Micro Nutrients • Essential micro nutrients, can’t make them yourself – Vitamins and minerals, most are essential – Info on most labels and at https://en.wikipedia.org/wiki/List_of_micronutrie nts • Non-essential does not mean “not needed” – Some amino acids – Vitamin D – Cholesterol, you do need this and you can make most of what you need Changing Needs with Age • Less calories are needed – Less physically active and less muscle mass – Body fat increases with age even when active • Some essential nutrient needs increase – Vitamin B-12 because absorption is less efficient with age – Vitamin D, because synthesis by sun on skin is less efficient with age, and calcium to avoid bone loss – Water. Body fat increases with age, so water % declines Exploiting the Nutrients • From your plate to your tissues – The journey through the digestive system More Range of Motion/Upper Body Stretches go with both to increase range of motion Hips and Midriff and More Digestive System Mouth • Chewing breaks food into smaller bits • The more time the food is in your mouth the better it is mixed with saliva and enzymes from your glands that aid digestion – Chew food as long as you can – Put down silverware or finger food between bites to help slow down Stomach • It’s a very sour place – Ph about 1.5-3, mucus protects stomach wall – Hydrochloric acid breaks down food and activates enzymes and kills germs • Stomach muscles “churn” to mix and break down food Upper Gastro Intestinal Tract • Liver produces bile stored in gallbladder – Enters small intestine and helps break down fat • Pancreas produces hormones that help regulate glucose uptake by cells – Also makes bicarbonates to help neutralize stomach acid as it enters the small intestine Lower Gastro Intestinal Tract • Most of the small intestine- point of action – Completes digestive processes and lets nutrients enter your system • Large intestine- point of reabsorption of water – Colon, the antechamber for exit Supplements • Do you need them? – Some supplementation may be needed • Especially with age – Most vitamins are water soluble and are naturally flushed if in excess • Not water soluble are vitamin A, D, E, and K • Fat soluble and toxicity from excess is possible • Not all supplements are the same, check with your doctor and balance with your diet Homework • Bring packaged food so we can look at ingredient labels References • • • • • • • • • • http://www.yourdictionary.com/nutrition http://www.who.int/topics/nutrition/en/ medical-dictionary.thefreedictionary.com/nutrition https://en.wikipedia.org/wiki/Essential_nutrient Eldergym.com http://www.livestrong.com/article/388545macronutrient-ratios-in-a-diet/ https://en.wikipedia.org/wiki/Dietary_fiber http://www.webmd.com/diet/guide/types-of-fatstopic-overview https://en.wikipedia.org/wiki/Protein_%28nutrient%29 Google images
