each &/or see following slides
• a. High blood pressure

3. Lactose intolerance
A. 2.Diet related diseases
• a. High blood pressure

broken down into glucose
by the enzyme lactase.
Sports Nutrition
athletes should eat complex-t-carbohydrates 3-4
hours before competing
drink lots of water to avoid dehydration
-Increase calorie intake
-Eat plenty of iron-rich foods
-Meet calcium needs to avoid bone fractures
-Supplements such as energy bars, sports
drinks and protein shakes should not replace
healthy food
Anabolic steroids are drugs that may cause
teens to stop growing, does cause high blood
pressure, heart & liver damage
C. Diet and Stages of Life
• Read SFL p 306-312 and write 2 facts for each &/or
see following slides

Nutrition before birth
Nutrition in infancy
Nutrition for children
Nutrition for teens
Nutrition for adults
Nutrition for older adults
C. Diet and Stages of Life
• Nutrition before birth
• Pg women need folic acid
– An unborn child only gets nutrients through the mother’s
diet.
– Pregnant women should consume 2-3 daily
servings from the milk group and 2
added servings from the grains group
for calories.
– An extra serving from both the fruit
and vegetable groups will provide
needed vitamins, minerals and fiber
C. Diet and Stages of Life
• Nutrition in infancy
– Breast milk or formula is a baby’s first food.
Breast milk is designed to meet most of the
baby’s nutrient needs. Formula also provides
needed nutrients.
– Babies need vitamin C early in life
– Babies should not be given
solid foods before 4 months.
C. Diet and Stages of Life
• Nutrition for children
– Preschoolers need larger portions of nutrients
to support their rapid growth. Vitamins A & C
are vital during this period. Raw fruits &
vegetables can be given as snacks to meet
the vitamin needs
– School age children need the energy and
nutrients provided by milk,
breads, meats, fruits and
vegetables
C. Diet and Stages of Life
• Nutrition for teens
– Rapid growth during the teen years creates
great nutritional needs. Busy schedules often
cause teens to skip meals.
– Many teens select snack foods
high in fats and sugars and low
in other nutrients. Therefore,
nutrient needs do not always
get met.
C. Diet and Stages of Life
• Nutrition for adults
– Gradually metabolism begins to slow, causing
adults to need fewer calories
– The need for nutrients does not
diminish. Adults need healthy
foods that will supply the
Nutrients and calories.
Ex. Fruit Juice over Cola
C. Diet and Stages of Life
• Nutrition for older adults
– Many older adults are less active than younger
adults, which causes them to need fewer calories.
– Older adults still need the same amount of most
nutrients as they did when they were younger.
– The need for calcium actually increases for adults
over 50
