Through the Looking Glass A Look at Fluid Needs & Beverage Choices Developed by: Huntington Beach Union High School District Network for a Healthy California
Background Info Water is essential for life Maintaining hydration is important for physical and mental performance The human body is largely made of water (about 60% for adults) Although we can live for up to 50 days without food, without water we will survive only a few days, even in a cool climate.
Why is water important? Water is used to Maintain blood pressure Help digest and absorb food Transport nutrients Remove waste materials Keep joints lubricated Regulate body temperature
Fluid Regulation Total water in = Total water lost Water is lost by: –Evaporation Perspiration (sweat) From our respiratory tract –Urine –Feces Sources of Water: –About 20% from food –About 80 % from drinking water and other beverages
When we lose water When we do not replace fluids, it affects our performance We have a shorter time before we become exhausted We decrease our chances of winning a game or we perform poorly We increase our risk for dehydration
How much should we drink? The vast majority of healthy people can meet their hydration needs by letting their thirst be their guide General Recommendations –Drink more water throughout the day –Make smart beverage choices such as non fat milk and 100% juice –Limit sweetened beverages
What are the signs are dehydration? % DehydratedSymptoms 0 – 1%Thirsty 2-5%Headache, fatigue, impaired performance, nausea, dry mouth, chills, clammy skin 6%Increased body temperature 8%Increased body temperature, dizziness, weakness Over 8%Heat stroke – sweating stops, high temperature, disorientation, death
Fluids Needs for Endurance Athletes Fluid needs are greater with increased physical activity and rises in temperature (due to an increased rate of fluid loss) –Sweat losses of 1.5 L/hour commonly occur in endurance sports –Under hot conditions, sweat rates can exceed 2.5 L/hour –Marathon runners can lose 6% to 8% of body weight during the 26.2-mile event Dehydration occurs when fluid loss exceeds intake
How Much Should We Drink for Physical Activity We should drink: 16 oz about two hours before physical activity 5 – 10 oz every 15 minutes during an activity Drink as much as possible within the last 15 minutes of an activity Continue to drink to replace fluids lost during sweating
A Look at the Beverages Well Discuss Today Milk Fruit Juice Soft Drinks Sports Drinks Energy Drinks Water
Milk Excellent source of Calcium, Potassium, & Vitamin D My pyramid recommends people above the age of 8 consume 3 servings of dairy/day Varieties –Lactose-Free –Non-fat, low-fat (1%), reduced-fat (2%), and whole-milk –Flavored milk
Fruit Juice 1 cup 100% juice = 1 cup of fruit My pyramid recommends 1 ½ - 2 cups of fruit/day for most people 100% juice contains many vitamins & minerals but very little fiber For the benefits of fiber, try to eat whole or cut-up fruit
Soft Drinks High Fructose Corn Syrup is the main sweetener in soft drinks The average American consumes 132 calories/day from High Fructose Corn Syrup The intake of High Fructose Corn Syrup rose 1000% from 1970 to 1990
Soft Drinks Consumption of soft drinks leads to increased energy consumption People do not compensate for the added energy they consume in soft drinks with their intake of other foods Soft drinks can displace other nutrients –An increase in soft drink consumption is related to a decrease in milk and calcium consumption
Sports Drinks Contain carbohydrates and electrolytes Are not helpful unless your exercise lasts beyond 60-90 minutes –Ex: long-distance cycling, endurance running, or competing in a tournament with more than one game/day A typical sports drink contains about 60 calories/8-oz. serving
Energy Drinks 31% of kids 12-17 years old (7.6 million teens) say they consume energy drinks Ingredients vary from drink to drink but most brands contain caffeine May also contain other ingredients such as B Vitamins, Taurine, Guarana & Ginseng These stimulating properties can boost heart rate & blood pressure (sometimes causing palpitations), and prevent sleep

Energy Drinks Some people are more sensitive to caffeine than others Drinking multiple Energy Drinks in one day can be dangerous since it could lead to high dosages of caffeine Think of Energy Drinks as highly- caffeinated beverages rather than natural alternatives –Claims such as improved performance and concentration can be misleading
Water Water consumption is necessary for metabolism and for normal physiologic functions May provide essential minerals such as calcium, magnesium, and fluoride. Calorie-Free Low-cost
Tips to Drink More Water Always carry a water bottle with you Drink a glass of water with each meal and in between meals Replace your afternoon soft drink with water Keep water cold, it tastes better! Add lemons or limes to your water
