6SIX TYPES OF NUTRIENTS Carbohydrates Proteins Vitamins Minerals Fats Water
7CARBOHYDRATES CARBOHYDRATES The starches and sugars that provide the body with most of its energy. Great source of fiber.2 types of CARBS.1. Simple2. Complex
8SIMPLE CARBOHYDRATES Simple Carbohydrates found in fruit, sugar and milk
9COMPLEX CARBOHYDRATES found in starchy foods, breads, cereals, dry beans, potatoes, peas, corn and beets
10PROTEINSPROTEINSNeeded to build, repair, and maintain body cells and tissues(particularly muscle).Secondary energy source – to carbohydratesEspecially important during growth periods (childhood, adolescence, …).Meat, fish, poultry, eggs, milk, cheese, nuts, and dry beans are sources of Protein.Made up of AMINO ACIDS
11AMINO ACIDS 22 Amino Acids Your body can make 13 of them. The other 9 are called ESSENTIAL AMINO ACIDS, and they must come from the food you eat.Complete Proteins come from animal sources and contain all 9 essential amino acids.Incomplete Proteins come from plant sources and lack at least 1 essential amino acid.Vegetarians can combine plant foods to make complete protein, like beans and rice.
12VITAMINSVITAMINSSubstances needed in small quantities that help regulate body functions.2 Groups of VitaminsWater – solubleVitamin C & BFat – solubleVitamin A D E & K
13VITAMINS Water – soluble Fat – soluble Can NOT be stored in the body Must be included in your dietFat – solubleCan be stored in the body until needed.Since Vitamins can not be made by the body, they must be provided by your diet.Fresh fruits and vegetables, whole-grain breads, cereal products, and milk are rich sources of Vitamins.
14MINERALSMINERALSElements needed in small quantities for sturdy bones and teeth, healthy blood, and regulation of daily elimination.Whole grains, fruit, peas, spinach, raisins, and milk are good sources of minerals.

16FATSFATSA third source of energy and are essential for vital body functions.Insulate bodyCushion organsCarry fat – soluble vitaminsPromote healthy skin and normal growth
17SATURATED FATS Fats found in meats and dairy products Eating to much Saturated fat can raise blood cholesterol levels, increasing the risk of heart disease.room temp.
18UNSATURATED FATSFound mainly in vegetable oils, such as olive, corn, or canola oil, nuts and avocadosFats that remain room temp.
19WATERMost common nutrientMakes up 60% of the body
20WATER Carries nutrients through body Helps digestion Removes waste from bodyLubricates jointsKeeps body from overheating
21HEALTHY DIET SUMMARY Balance of nutrients Too much fat may lead to heart diseaseToo little protein hinders growthYou need a variety of healthy foods to get all the nutrients!
22CaloriesThe number of calories people should eat each day depends on several factors, including theirAgeSizeHeightGenderLifestyleOverall general health.A physically active 6ft 2in male, aged 22 years, requires considerably more calories than a 5ft 2ins sedentary woman in her 70s.
23Recommended Daily Calories According to the National Health Service (NHS), UK, the average male adult needs approximately 2,500 calories per day to keep his weight constant, while the average adult female needs 2,000.US authorities recommend 2,700 calories per day for men and 2,200 for women.It is interesting that in the UK, where people on average are taller than Americans, the recommended daily intake of calories is lower. Rates of overweight and obesity among both adults and children in the USA are considerably higher than in the United KingdomDiscussion on this slide (No notes)#2 Is it permanent, what would make it change..#3 Have class summarize last point
24Portion sizesIn industrialized nations and a growing number of emerging economies, people are consuming many more calories than they used to. Portion sizes in restaurants, both fast food ones as well as elegant places, are far greater today.The average cheeseburger in the USA 20 years ago had 333 calories, compared to the ones today with over 600 calories
