3The Big Texan Steak RanchAmarillo, TX
- Almost 42,000 people from around the world have
traveled to Amarillo and attempted to eat the
specially cut 72-oz. top sirloin steak, a baked
potato, salad, dinner roll and shrimp cocktail.
About 8,000 have succeeded in completing the feat
and joining the ranks of Big Texan champions. - Last year higher market prices for cattle pushed
the price to 72.00 for the meal.
4Pointers PizzaSt Louis, MO
- For years now, Pointers has offered a 500 prize
to any two-member team who can demolish an entire
10-pound, two-meat-topping, 28-inch pizza in an
hour without leaving the customer area. Teams
must call at least a day in advance and cannot
compete during lunch or dinner rushes. A pair of
recent winners advise ordering lean toppings such
as turkey and chicken, lest nausea become a
disqualifying factor. The Pointersaurus Challenge
costs 42, but the pizza sells briskly for
parties and office lunches at 35 for a cheese
pizza and 5 for each topping

9Nutrition
- Is the study of food and how our bodies use food
as fuel for our body and our health. - There is a link between lifetime nutritional
habits and these diseases - Heart disease
- Cancer
- Stroke
- Diabetes
10Foods Are Composed Of
- Carbohydrates
- Proteins
- Fats
- Vitamins
- Minerals
- Water
- ESSENTIAL NUTRIENTS The nutrients that we must
include in our diet. Our body does NOT
manufacture them.
11Nutrition
- Foods are various combinations of these
nutrients. - Example- meat is a lot of protein, water, fat,
vitamins, minerals, but very little CHO. - Energy (the ability to do work) for the body is
supplied by every bite that you eat. - Nutrients are released into the body by the
process of digestion, which breaks down food into
compounds that can be used by the body.
12Nutrients
- Food provides two different and distinct groups
of nutrients - Macronutrients (macro big) CHO, protein,
fats, water - Micronutrients (micro small) vitamins and
minerals
13Best Choices
14Six Classes of Essential Nutrients
15Ideal Eating Plan
- Recommendations
- Protein 10-35
- CHO 45-65
- Fat 20-35
- Saturated Fat lt 7-10
- Monounsaturated Fat - Up to 20
- Polyunsaturated Fat Up to 10
16Six Classes of Essential Nutrients
17Nutrition
- Alcohol Although alcohol is not an essential
nutrient, it does provide energy. - 7 Calories/gram
- Calories are the potential energy for the body
to produce work. - One Kcal represents the amount of heat it
takes to raise the temperature of 1 kg of water 1
degree Celsius.
18Carbohydrates
- Are organic compounds composed of carbon,
hydrogen and oxygen. - Found mostly in plant sources. The only animal
source is milk. - CHO are our brain food and some cells in the
nervous system only use CHO as fuel. They do not
utilize fat. - CHO also used during high-intensity exercise.
- AT LEAST 55 of our total calories should come
from CHO, with no more than 10-15 of these from
simple CHO sources.
19Carbohydrates
- They are classified as simple or complex.
- Simple are sugars, complex are starches or fiber.
20Simple Carbohydrates
- Sugars and starches occur naturally in many
foodsincluding milk, fruits, some vegetables,
bread, cereals, and grains. - These foods, however, provide many important
nutrients. - On the other hand, so-called added sugars-supply
added calories, but few nutrients. - Foods rich in added sugars include things like
soft drinks and desserts.
21Leading Sources of Calories in the American Diet
- 1. Regular soft drinks (7.1 of total calories)
- 2. Cake, sweet rolls, doughnuts, pastries
(3.6) - 3. Hamburgers, cheeseburgers, meat loaf (3.1)
- 4. Pizza (3.1)
- 5. Potato chips, corn chips, popcorn (2.9)
- 6. Rice (2.7)
- 7. Rolls, buns, English muffins, bagels (2.7)
- 8. Cheese or cheese spread (2.6)
- 9. Beer (2.6)
- 10. French fries, fried potatoes (2.2)
- Source Block, G. 2004. Foods contributing to
energy intake in the U.S. Data from NHANES III
and NHANES 19992000. Journal of Food Composition
and Analysis 17 439447.
22Choose Sensibly
- How much sugar is added to this???
23Choose Sensibly
- A sugar by any other name
- Read the label to locate hidden sugars in the
foods you consume. - Sugars are listed by many different names,
including brown sugar, corn sweetener, corn
syrup, fructose, fruit juice concentrate, glucose
or dextrose, high-fructose corn syrup, honey,
lactose, maltose, molasses, raw sugar, table
sugar, or sucrose, and syrup. - If one of these appears near the top of the
ingredients list, the food is probably high in
added sugars.
24Sugar
- Study in Annual Review of Nutrition found that
women ages 20-39 increased their daily caloric
intake from 1,652 to 2,028 (376 more calories). - Also during this time they the calories from
protein and fat. Primarily sugar intake
increased. - We now consume an additional 25 lbs./year of
sugar that previous years.
25High Fructose Corn Syrup
- Created in 1967, a combination of fructose and
glucose - Cheaper and 1.16 times sweeter than cane-derived
sugar - 1970 HFCS was in 1 of products
- 2000 HFCS in 42 of products
- According to 2008 USDA report 57 of all sugar
on the market is purchased by food and beverage
industry.
26Sugar
- Average American intake of added sugars males-22
tsps., females, 16 tsps. - This does not include naturally occurring sugars
found in foods such as milk and fruits. - The USDA recommendation
- 1600 calories/day no more than 6 tsp/day
- 2200 calories/day no more than 12 tsp/day
- 2800 calories/day no more than 18 tsp/day
27Chocolate Shake
28Complex Carbohydrates
- Complex carbohydrates consist of chains of many
sugar molecules - Found in plants, especially grains, legumes, and
tubers - Include starches and most types of dietary fiber
29Whole Grains
- Before they are processed, all grains are whole
grains consisting of an inner layer of germ, a
middle layer called the endosperm, and an outer
layer of bran - During processing, the germ and bran are often
removed, leaving just the starchy endosperm - Refined carbohydrates usually retain all the
calories of a whole grain but lose many of the
nutrients
30Whole Grains
- Whole grains are higher than refined
carbohydrates in fiber, vitamins, minerals, and
other beneficial compounds - Whole grains take longer to digest
- Make people feel full sooner
- Cause a slower rise in glucose levels
- Choose 3 or more servings of whole grains per day
31Complex Carbohydrates
- Complex CHO are broken down through digestive
processes to glucose for use by the body.
Glucose remains in the blood and some is
converted to glycogen and is stored in the liver,
muscles, and kidneys. - The body can pack about 400 gr. of glycogen.
Together with glucose stored, there are about of
1,800 calories of energy. - Diets low in CHO promote lean tissue and water
loss. Each gram of glycogen is stored with 2-3
grams of water. Thus low CHO intake leads to
water loss.
32CHO and Energy
- Glucose is then carried into your cells with the
help of insulin, a hormone secreted by your
pancreas. - Remember. . .with oxygen, glucose is converted to
ATP in the mitochondria of the cell. - Without oxygen, red blood cells change glucose to
energy (ATP), but lactic acid is a byproduct.
33CHO Uses
- CHO also protect muscles. When you need energy
the body looks for CHO first. - If none are available, because you are on a low
CHO diet or you have a condition the inhibits the
body from using CHO, the body will use its own
protein tissues (muscles). - CHO also
- Regulate the amount of sugar circulating in the
blood, so that your cells get the energy they
need. - Provide nutrients for the friendly bacteria in
the intestinal tract that help digest food. - They help the body absorb calcium.
- They help to lower cholesterol levels and
regulate blood pressure, especially fiber.
34Where do we get CHO?
- Most important sources of CHO are plant foods
fruits, vegetables, and grains. - Milk and milk products do contain CHO.
- Meat, fish and poultry do not have CHO.
- You need
- 6-11 servings /day of grain foods (bread,
cereals, pasta, rice) - 2-4 servings of fruit
- 3-5 servings of vegetables
35Glycemic Index
- Glycemic Index Is the measure of how strong of
an effect a CHO food has on blood glucose levels. -
- A high glycemic index CHO tends to cause a quick
and dramatic rise in glucose and insulin levels.
High glycemic foods can increase appetite, and
are linked to increased diabetes and heart
disease.

38FiberA Closer Look
- Dietary fiber non-digestible carbohydrates and
lignin that are present naturally in plants - Functional fiber non-digestible carbohydrates
isolated from natural sources or synthesized in a
lab and added to a food or supplement - Total fiber dietary fiber functional fiber
39Types of Fiber
- Soluble (viscous) fiber fiber that dissolves in
water or is broken down by bacteria in the large
intestine - Slows the bodys absorption of glucose
- Binds cholesterol-containing compounds
- Sources pears, apples, prunes, oat, oranges,
zucchini
40Types of Fiber
- Insoluble fiber fiber that doesnt dissolve in
water - Makes feces bulkier and softer
- Helps prevent constipation, hemorrhoids, and
diverticulitis - Sources bran (outer layer of wheat/corn), the
skins of fruit and root vegetables, and leafy
greens - Fiber adds no calories to your diet. There is no
fiber in meat, fish, poultry, milk, milk products
and eggs.
41Recommended Intake of Fiber
- Women 25 grams per day
- Men 38 grams per day
- Americans currently consume about half this amount
42Why Do We Need Fiber?
- Fiber helps to speed the passage
- of waste through the intestinal
- tract which lowers the risk of
- cancer because any potential
- carcinogens are moved out quickly.
- Water-soluble fiber binds with cholesterol in the
intestinal tract and blocks the absorption and
helps the body release it. Thus, a lower total
cholesterol level!! - Less cholesterol means less risk of heart disease!
43Refined vs. Unrefined Fiber
- The processing of package foods can remove fiber.
- REFINED CHO Retain all the calories, but are
lower in fiber, vitamins, and minerals. - UNREFINED CHO (Whole Grains) Take longer to chew
and digest and enter the blood more slowly.
Thus, you feel fuller longer, more anti-oxidant
vitamins and phytochemicals and decrease risk of
diabetes. - Example Long grain rice vs Minute Rice
44Carbohydrates
- Recommended to consume 45-65 (275-300 grams) of
total calories as CHO, with not more than 10
from simple CHO. Athletes may need more,
especially endurance athletes! Marathoners CHO
load right before the event because they exercise
for longer than 90 minutes. - Choose fresh fruits, vegetables, and whole grains
to fuel the body!

46FATS (Lipids)
- The most concentrated source of energy. We store
50 times more energy in the form of fat, than in
CHO. -
- 3500 calories 1 pound of fat.
- The body burns fat as an energy source for
periods of rest and low to moderate physical
activity. About 70 of the energy we need comes
from fat, 30 from glucose, except for high
intensity work. - Function of fats
- Insulation
- Cushion body organs
- Provide energy
- Vitamin storage (fat soluble A, D, E, K)
- Add flavor and texture to foods.
- Some fat is invisible, as it is tucked in and
around our organs. It is a part of every cell
membrane. Brain tissue is also rich in fat.
47Fats in Food
- Food contains 3 kinds of fats triglycerides,
phospholipids and sterols. - Triglycerides are the fats you use to make
adipose tissue and what you burn for energy. - Phospholipids help to carry hormones and vitamins
through the blood and across cell membranes. - Sterols are fat and alcohol compounds with no
calories. - Vitamin D, testosterone and cholesterol are
sterols.
48Right Amount of Fat
- Balance must occur to get the right amount of fat
in your healthy eating plan. - Too much risk of obesity, diabetes, heart
disease, cancers - Too little infants and children do not grow,
not able to absorb A, D, E, K that help with
vision, smooth skin, immune system and
reproductive organs - Fat should make up lt30 of calories, with no more
than 10 from saturated fat sources. - For 2000 cal./day that would be 600 calories or
fewer from fat and 200 calories or fewer of that
from saturated fat.
49Foods and Fats
- Fruits and vegetables have only traces of fat,
primarily unsaturated fatty acids. - Grains have very small amounts of fat.
- Dairy products vary. Cream is high-fat. Whole
milk and cheeses are moderately high in fat.
Skim milk and skim milk products are low fat
foods. Most fat in dairy is saturated. - Meat is moderately high in fat mainly
saturated. - Chicken and turkey are lower in fat.
- Fish may be high or low, but is primarily
unsaturated fatty acids. - Vegetable oils, butter and lard are high fat.
Most oils are unsaturated. Lard and butter are
saturated.
50FATS
- Triglycerides are the most abundant type of fat
98 of the fat eaten and stored in the body. -
- Triglycerides are composed of a glycerine
molecule (an alcohol) plus three fatty acid
chains. Fatty acids are the building blocks of
fats. - Fatty acids are made up of a chain of carbon
atoms with oxygen attached at the end and
hydrogen atoms attached along the length of the
chain.
51Types and Sources of Fats
- Saturated fat a fat with no carbon-carbon
double bonds usually solid at room temperature - Found primarily in animal foods and palm and
coconut oils, dairy products, baked goods,
Crisco, butter. - Monounsaturated fat a fat with one
carbon-carbon double bond usually liquid at room
temperature - Sources Avocados, canola oil, cashew nuts,
olives, olive oil, peanuts, peanut oil, peanut
butter, almonds, pecans - Polyunsaturated fat a fat with two or more
carbon-carbon double bonds usually liquid at
room temperature - Found in certain vegetables, fatty fish, corn
oil, cottonseed oil, filbert nuts, safflower
oil, sunflower oil, soybean oil, walnuts.

53Choose Sensibly
54Types and Sources of Fats
- Two key forms of polyunsaturated fats
- Omega-3 fatty acids are produced when the endmost
double bond of a polyunsaturated fat occurs three
carbons from the end of the fatty acid chain - Found primarily in fish
- Omega-6 fatty acids are produced when the endmost
double bond of a polyunsaturated fat occurs six
carbons from the end of the fatty acid chain - Found primarily in certain vegetable oils,
especially corn, soybean, and cottonseed oils
55Omega-3 Fatty Acids
- Promotes heart health. May prevent blood clots,
aids heart to beat in a steady rhythm, reduces BP
and risk of heart attack and stroke. - Recommended to have two or more servings of
fish/week. Examples salmon, tuna, trout,
mackerel, sardines and anchovies. - Plant sources include dark green leafy
vegetables, walnuts, canola oil and flax seeds.
56HYDROGENATION
- The process of adding hydrogen to an oil to
improve the texture of foods and increase the
shelf life. (Trans Fatty Acids) - Turns a liquid into a solid. Example vegetable
oil converted to margarine. - Trans fats are found in cookies, crackers, fried
chicken, peanut butter, pies, cakes, French fries
and many more. - Studies have shown that gram for gram, trans
fats are more harmful than saturated fats. - Trans fat connected to development of heart
disease. (Raises LDL, lowers HDL). Heart disease
risk could be cut in half by reducing trans fats
by 4 grams/day. - Read the nutritional labels look for
partially-hydrogenated vegetable oils, which
tells you it has trans fat in it! - Choose liquid oils over margarine or shortening
for cooking. Look for trans-free soft margarine
over stick margarine.

60FATS
- Two Essential FA Linoleic fatty acid (plant
foods omega-6 family) and alpha-linolenic fatty
acid (fish omega-3 family) Deficiencies are
rare in U.S. - Recommended that lt30 of total calories come from
fat sources, with no more than 7-10 from
saturated fat, up to 10 from polyunsaturated
fats, and up to 20 from monounsaturated sources. - Average American consumes 33 (or 75 grams) of
calories from fat.
61Cholesterol
- Is a type of fat (sterol) found in animal
products only. - Also manufactured in the body in the liver.
- Cholesterol does help enable nerve to send
messages back and forth protects the integrity
of cell membranes helps to absorb Vit. A,D,E,K,
is a base to build hormones such as estrogen and
testosterone. - But. . . high levels of cholesterol are linked to
coronary artery disease. - RDA for dietary cholesterol is less than 300
mg./day.
62Protein
- Protein comes from the Greek word, protos,
meaning of prime importance. - Proteins are a major component of all plant and
animal tissues, second only to water. - Our bodies constantly assemble, break down and
use proteins. - When we eat more protein than we need, the excess
is either used to make energy or stored as fat.
63Protein
- Protein mainly associated with animal foods
beef, chicken, fish, or milk. - But, plant foods also have protein. Dried beans
and peas, grains, nuts, seeds and vegetables.
64Protein
- Human body is full of proteins.
- There are proteins in the outer and inner
membranes of every living cell. - Hair, nails, and outer layers of skin are made of
the protein, keratin. - Muscle tissue contains proteins.
- Bone has lots of protein in the inner structure.
- RBC have hemoglobin (carries oxygen in blood) and
globin is protein.
65PROTEIN
- Are complex chemical structures containing
carbon, hydrogen, oxygen and nitrogen combined
into chains called amino acids. - Amino Acids are the building blocks of protein,
or links to create protein.
66Uses of Protein
- Proteins from foods are broken down into amino
acids by digestive enzymes. - Body has 20 different amino acids in foods to
choose from when building sequences of AA. - 9 of the amino acids are essential because they
cannot be manufactured in the body, only obtained
through foods. - Body can manufacture the other nonessential 11.
- When AA link together to form a protein, their
characteristics work together to determine their
specific function.
67PROTEIN
- COMPLETE PROTEIN High quality protein that
provides all nine essential amino acids. - Examples Meat, poultry, fish, eggs, milk,
cheese, soybeans - Plant sources are usually low in 1 or 2 amino
acids. - INCOMPLETE PROTEIN Low quality protein that
supply only some of the 9 essential proteins. - Examples Beans, peas, nuts
- Come from plant sources.
- Foods can be mixed and matched to produce
complete proteins. Example Peanut butter
sandwich on whole wheat rice and beans cheese
sandwich on whole wheat yogurt with nuts.
68Protein Sources
- 3 ounces lean meat, poultry, or fish
- 1/2 cup tofu
- 2025 grams of protein
- 1 cup legumes
- 1520 grams of protein
- 1 cup milk or yogurt or 1-1/2 ounces cheese
- 812 grams of protein
- Cereals, grains, nuts, vegetables
- 24 grams of protein per serving
69Protein Requirements
- Need around 15 of total calories from protein or
0.8-1.0 grams/kg of body weight. (0.4
grams/pound) - On a 2000 calorie/day plan that would be about
300 calories (4 cal./gram) - About 2/3 of protein intake in the American diet
is from animal sources, also high in saturated
fat/cholesterol. - 175 lb. man needs about 63 grams/day. This would
be two or three 3-ounce servings of lean meat,
fish, poultry. (21 grams/3-ounce serving)
70WHO NEEDS EXTRA PROTEIN?
- Anyone who is building new tissue quickly needs
more than 0.8 grams. - Infants many need as much as 2.0 grams/kg
- Adolescents need as much as 1.2 grams/kg
- Pregnant women need an extra 10 grams/day. Those
who are nursing need an extra 15 grams/day in the
first 6 months. - Injuries may increase your protein needs,
especially if there has been a lot of blood loss,
as the protein is needed to make new hemoglobin. - Athletes?? Research suggests that athletes
easily meet their requirements about an
additional 0.5-0.8 gr./kg per day in their normal
diet. - You cannot force your body to build muscle by
pumping in more protein than you need, any more
than you can make your car run faster by adding
more gas to a full tank. Extra protein does not
build muscles only regular workouts fueled by a
mix of nutrients can do that!!
71Athletes
- For resistive training athletes 1.7 to 1.8
gr./kg - For endurance athletes 1.2 to 1.4 gr./kg.
- Average American consumes almost twice as much
protein as they need, so most athletes already
get enough. - Consuming larger than normal amounts of protein
does not enhance physical performance, as that is
not the function of protein. - Protein supplements???? If excess protein means
excess calories, then fat weight, not muscle
weight is gained. - Purified protein supplements can contribute to
calcium losses and therefore harm bone health. - Excess protein means excess nitrogen that must be
excreted, a risk for dehydration. - Supplements of some single amino acids can
interfere with absorption of other amino acids. - THUS A HEALTHY DIET WILL FUEL YOUR EXERCISE!

73VITAMINS
- Vitamins are organic (containing carbon)
compounds required in small amounts to regulate
cellular functions. - Vitamins do not provide energy, but help to
release stored energy in CHO, fats, protein.
Vitamins also critical in production of red blood
cells and maintenance of nervous, skeletal and
immune systems. Vitamins prevent nutritional
deficiency diseases and promote healing and good
health. - Most are obtained through the diet, except for
Vitamin D (obtained through sunlight) and Vitamin
K which the body can produce from bacteria in the
intestines.
74Vitamins
- Humans need 13 vitamins. They are classified as
fat-soluble or water-soluble. - Fat-soluble (dissolve in fat) are A, D, E, K and
are stored for long periods in fat tissue and
liver. Over-consumption can lead to toxic
effects. - Water-soluble are 8 B-complex vitamins and C.
They are absorbed directly into the blood, used
or excreted. Need to be replaced frequently. - B-complex include biotin, folate, niacin,
pantothenic acid, riboflavin, thiamine B6, and
B12 - Vitamin Sources are abundant in fruits,
vegetables and processed foods such as cereals
which have been enriched with vitamins. - Limit cooking to preserve nutrients and eat fresh
fruits/veges when possible.
75A, D, E, K
- Vitamin A moisturizing nutrient for skin and
membranes. Vision vitamin. Promotes growth of
healthy bones and teeth. Helps immune system
fight off infections. Sources whole milk,
eggs, butter yellow, red, dark green
fruits/vegetables. - Vitamin D Is essential to help body absorb
calcium for bones and teeth. Sources sunlight,
fish oils, egg yolks - Vitamin E Helps to maintain a healthy
reproductive system, nerves, muscles. Helps
maintain a healthy heart. Sources vegetable
oils, nuts, whole grains, green leafy vegetables. - Vitamin K Blood clotting. Helps to make bone
and kidney tissues. Sources dark green leafy
vegetables, cheese, liver cereals, milk.
76MINERALS
- They are inorganic (non-carbon containing)
substances that exist freely in nature. They aid
in growth and maintenance of body tissues, normal
heart rhythm, body water supplies, acid-base
balance of the blood and nerve impulse conduction.
77Minerals
- There are at least 17 essential minerals.
- Major Minerals (required in amounts exceeding 100
mg) Calcium, phosphorous, potassium, sulfur,
sodium, chloride, and magnesium. - Trace minerals (required in smaller amounts)
include fluoride, iron, selenium, zinc, arsenic,
boron, chromium, cobalt, copper, iodine,
manganese, molybdenum, nickel, silicon, and
vanadium. - Minerals most commonly lacking in the diet are
iron and calcium. - Sodium, potassium and chloride are the primary
minerals lost through perspiration. Potassium is
essential for maintenance of the heart beat
found in citrus fruits/juices, bananas, dates,
nuts, fresh vegetables, meat, and fish. - Iron deficiency leads to anemia. Iron is an
essential part of hemoglobin. - Calcium deficiency leads to osteoporosis.
78ANTIOXIDANTS
- Substances that help prevent harmful effects
caused by oxidation within the body. - Free radicals or oxygen free radicals are
unstable elements formed when the body uses
oxygen or breaks down certain fats or protein as
a normal part of metabolism. - Cigarette smoke, radiation (x-rays), alcohol,
heat and certain pollutants also produce free
radicals. - This unstable molecule is missing an electron and
will react with any molecule it encounters to
take an electron. This damages cell membranes
and mutates genes. This can lead to aging,
cancer, CVD, and degenerative diseases such as
arthritis.
79Antioxidants
- Antioxidants react with free radicals and donate
lost electrons. They help by blocking the
formation and action of free radicals and repair
the damage they cause. - Fruits and vegetables are rich in antioxidants!
Examples Vit. C, A (beta-carotene), E and
selenium. It is best to get the antioxidants
from foods, not supplements.
80PHYTOCHEMICALS
- Phytochemicals means plant chemicals and are
found only in plant food. They are not vitamins
or minerals, but are a compound found to help
prevent chronic diseases, especially cancers. - There are hundreds, maybe thousands of
phytochemicals in fruits and vegetables. Some
examples - Allyl Sulfides garlic, onions
Isoflavones soybeans Polyphenols green tea,
grapes Saponins beans and legumes. - Antioxidants are a particular type of
phytochemical.
81VEGETARIANISM
- Many choose to follow a vegetarian diet.
- Four types of vegetarian diets.
- Vegans Considered true vegetarians. Diets are
void of meat, chicken, fish, eggs or milk
products. Vegans primary sources of protein are
vegetables, fruits, and grains. Vegans may have
to supplement diet with B12, normally found only
in meat products. - Lactovegetarians Eat dairy products, fruits,
and vegetables but do not consume other animal
products (meat, poultry, fish or eggs) - Ovolactovegetarians They eat eggs as well as
dairy products, fruits, and vegetables but do not
consume meat, poultry, and fish. - Semivegetarians Eat fruits, vegetables, dairy,
eggs, and a small selection of poultry, fish and
other seafood. They do not consume any beef or
pork.
82Choose and prepare foods and beverages with
little salt (sodium)
- The human body requires 500 mg Na/day.
- Average American consumes about 4,000-6,000
mg/day. - High Na intake associated with HTN.
- USDA recommendation no more than 2,300 mg/day or
about 1 tsp. NaCl/day.
83Play it safe with food.
- Know how to prepare, handle, and store food
safely to keep you and your family safe - Clean hands, food-contact surfaces, fruits, and
vegetables. To avoid spreading bacteria to other
foods, meat and poultry should not be washed or
rinsed. - Separate raw, cooked, and ready-to-eat foods
while shopping, preparing, or storing. - Cook meat, poultry, and fish to safe internal
temperatures to kill microorganisms. - Chill perishable foods promptly and thaw foods
properly. - Keep food safe to eat.
- Food-borne illness is caused by eating foods that
contain harmful bacteria, toxins, parasites,
viruses, or chemical contaminants. - S/S of having eaten unsafe food may appear within
half an hour, or may not develop for up to 3
weeks.
