Nutritional Genomics

A science studying the relationship between the human genome, nutrition, and health. It can be divided into two disciplines 1) Nutrigenomics = Studies the effect of nutrients on health through altering genome, proteome, metabolome and the resulting changes in physiology. 2) Nutrigenetics = Studies the effect of genetic variations on the interaction between diet and health with implication to susceptible subgroups.

Lean Body Mass

Consists of muscle, bone, organs, connective tissue, and water. Calculated by subtracting body fat from total body weight : Total body weight is lean plus fat. (LBM = BW - BF)

Older American Act

(OAA) Enacted in 1965, supports a range of home and community-based services, such as meals-on-wheels and other nutrition programs, in-home services, transportation, legal services, elder abuse prevention and caregivers support.

CDC growth charts (How are they used and what values/units are on the axis)

They are used to determine the percentage of children, from ages 2 to 19, who are Obese. The Y-axis consists of the percentage, while the X-axis consists of the age, divided by selected years.

Food Sciences

Where agriculture meets the consumer. The different types are Food microbiology and safety (Microorganisms on food?), Food chemistry and composition (Compounds in foods?), Food processing(Preserve foods and prevent spoilage?), Government regulations(Laws and regulations that govern food industry), Food quality and quality control(Measure flavor, color, texture of foods?)

Taste panels

AKA sensory panel, may be described as a group of testers who have exceptional sensory faculties and can describe products on the basis of taste, smell or feel. Test using two varieties of the same food, generate random 3 number ID codes for each food.

Capital investment

Things like equipment and buildings. This is expensive for a company to take on, and makes getting a new product on the store shelves very difficult, even if it is a really good product. Also, if your getting something on the shelf, that means that something else if coming off.

Value added

the gross value of the product minus the costs of raw materials and energy.

gourmet convenience

A degree of innovation that makes a product more attractive to customers and consumers. Includes things such as (Less prep time, Less cooking at home, More convenient sizes, Comfort of a brand name)

Food borne illness

Diseases, usually either infectious or toxic in nature, causes by agents that enter the body through the ingestion of food. Every year, results in an estimated 48 million cases (about 1 out of 6 people), 3000 deaths, economic loss between 10-83 billion dollars, 325,000 people hospitalized.

Salmonella

(Bacteria) Can be found on pretty muh any food product that you are likely to consume. Source is from raw produce such as melons, tomatoes, alfalfa sprouts, and orange juice. Raw meats, poultry, milk, and other dairy products, shrimp, frog legs, yeast, coconut, pasta, and chocolate are most frequently involved. Individuals carrying this organism but exhibiting no symptoms of illness could contaminate produce due to poor hygiene practices.

Hemolytic Uremic Syndrome

An illness that is derived from the bacteria E.Coli.

Listeria monocytogenes

The cause of an outbreak of a food-borne illness was traced to unpasteurized milk; symptoms included fever, nausea, headache. The likely source is:

Clostridium botulinum

produces preformed, heat-labile toxin that inhibits ACh release at the NMJ, causing botulism (flaccid paralysis). In adults, dz is caused by ingestion of preformed toxin. In babies, ingestion of bacterial spores in honey causes dz (floppy baby syndrome). BOTulinum is from bad BOTtles of food and honey.

Food danger zone

40-140 degrees

FATTOM

How microorganisms survive and thrive in foods we eat: Food, Acidity, Time, Temperature, Oxygen, Moisture (conditions needed for bacterial growth)

Pathogen

Humans are possibly infected after consumption of infected cows or cow products that contain infected brain tissue. POPS- persistent organic pollutants. Accumulate in the environment and the human body

GRAS

Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements.

HACCP

Hazard Analysis and Critical Control Points or is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe, and designs measurements to reduce these risks to a safe level. Program that has established the foundation for others in managing food production to reduce the chances of food borne outbreak. Set forth the seven principles: 1. Conduct a hazard analysis to identify potential hazards that could occur in the food production process. 2. Identify the critical control points (CCPS), the points I the process where the potential hazards could occur and can be prevented hazards could occur and can be prevented and/or controlled 3. Establish critical limits for preventive measures associated with each CCP. A critical limit is as criterion that must be met for each CCP. (Where appropriate critical limits may reflect relevant current regulations) 4. Establish CCP monitoring requirements to ensure that each CCP stays within its limit. Monitoring may require materials or devices (such as thermometers) to measure or otherwise evaluate the process at CCPs. 5. Establish corrective actions if monitoring determines that a CCP is not within the established limits. 6. Establish effective record-keeping procedures that document that the system is working properly Guidelines to promote food safety at every step of food production: the farm, storage, retail stores, restaurants, and consumers.

Sustainability

A set of policies or practices by which societies can ensure that the people of the future have the same access to resources and thus the same economic and environmental opportunities as people living today. 3 major concepts: ecology, economy, and health.

French paradox

Effects of the nutritional status on fertility for men and women

Underweight and, to a larger degree, overweight and/or obesity, are related to the enhanced risk of infertility.

The main nutritional needs of pregnancy

-weight gain: -increased nutrient needs -supplements -hydration caloric needs increase by 250-300 calories per day protein increases by 25 grams per day carbs increase by 175 grams per day vitamins and minerals increases by 30% iron increases from 18-27 mg per day folate, zinc 300mL additional fluid intake

Benefits of breastfeeding for the mother and the baby

Protects babies against childhood illnesses (Diarrhea, respiratory infection, some childhood cancers, autoimmune disease, obesity), Less likely to experience allergies and intolerance, ear infections, vomiting, pneumonia, wheezing, meningitis, sudden infant death syndrome, rich in antibodies; mothers: Lose weight faster, less stress during postpartum period, stronger bonds with baby, decreased risk of breast and ovarian cancer, saves money.

Changes in caloric and protein needs through the life stages, total and per unit of body weight - kcal/kg of body weight and protein in grams per kilogram or pound of body weight. You do not need to remember the exact numbers but know THE TRENDS

increase in the amount of protein decrease in the total calories 2000-1800

Anorexia and bulimia among children (Note that children according to CDC are up to age 20 years

young girls are more susceptible because sensitive about weight/appearance during adolescence. -parents should look 4 signs, discourage meal skipping, discourage bad food habits like skipping breakfast or eating poor food - 2.7% of children

Food related behaviors of teenagers

Sound nutrition can play a role in the prevention of several chronic diseases, including obesity, coronary heart disease, certain types of cancer, stroke, and type 2 diabetes more than two-thirds of adolescents, especially boys, adolescents from rural environments, and overweight adolescents, have unsatisfactory knowledge about dietary recommendations, sources of nutrients, diet-disease relationships, and dietary habits

Weight status of children and teenagers in U.S. - trends

18% of children and teens are obese Amount has nearly tripled since 1970

Caffeine and alcohol in breast milk and complementary food recommendations

Breast milk can transfer caffeine from mother to baby, high caffeine intake in nursing can make babies irritable. Small amounts of caffeine and alcohol may be tolerated as baby grows, but daily intake is not recommended. It is recommended that if these are in the system, that they pump first to rid the milk of them, and then breast feed. Avoid milk, peanuts, eggs, and wheat.

In what way microorganisms, freezing, and heating, and salt affect food - flavors, texture, etc.

Heating (Pasteurization) is when food is heated to temperature below boiling point that is high enough to kill any bacteria that would spoil the food. Examples are things such as milk, wine, etc. It keeps the food safe while maintaining the same taste and texture. Salting (Adding of Nitrates and Nitrites) is used in the curing and smoking process that have been used for centuries to preserve meats. It is part of what gives foods such as ham, hot dogs, and lunch meats their pinkish color. When food is salted, it removes much of the moisture and deters bacterial growth. Microorganisms work to spoil and make food dangerous, the other methods are some of the processes used to enhance preservation in food manufacturing.

Agencies/organizations in U.S. and Florida (FL) responsible for safety and production of food.

United States Department of Agriculture (USDA) - Oversee the production of meat and dairy products Florida Department of Agriculture and Consumer Services (FDACS) - Oversee food products that don't cross the state line, Handle food that is produced and distributed locally, unlike state-line overseers.

Types of "growth" for a company

Categories and characteristics of new food products

Line Extension (A variant of an established product, often a new flavor in a line of products) Re-positioned products (The re-purposing of a product, for example the many uses of baking soda. usually requires R&D, new packaging, new marketing strategies, possibly legal review) New for of existing product (Consumers must perceive an added value of the new form, for example Rice Roni to Rice Roni express), Reformulation (Often labeled "new and improved", may be in response to ingredient cost issues, consumer complaints, regulatory issues, problems with getting an ingredient, sometimes there is marketing change but most of the time goal is for consumer to not notice a change) New packaging (Range of R&D effort depends on packaging novelty, Distribution remains same, however will probably require packaging line equipment changes, Recent trend in past 10 years has been towards single-serve portions also transition from glass to plastic) Innovative products (Innovation implies a clever improvement of something already in existence, There is a fairly high degree of risk/expense involved, especially to those who are the trailblazers in a category, May or may not require a lot of R&D; will probably require a lot of marketing and sales support.Example: Baby cut carrots) Creative products (Create implies bringing something completely new into existence, Usually require huge investments in R&D, legal/patents, manufacturing lines, high risk high reward, truly creative products are rare, Often creative foods are ingredients that are then used in other foods, Might even be GMOs, example is a refined sugar for "light" drinks) -Convenience, Shopping, Specialty

Customer and consumer and marketplace

Customer - The purchaser, the one who buys in the marketplace. The gatekeeper Consumer - Uses what is purchased by the customer (the of course can be the same person), consumers can influence the customer (children telling parents what they want to eat) Markets - A market is conceptual (not a place), represents a need that marketers hope to turn into a want, that is an opportunity to sell, example: the market for organic foods) Marketplace - physical retail outlet where products are sold. for example: super and farmer's markets, vending machine, On-line provisioners)

Characteristics and processes leading to development of successful new food products

Looking at 80-90% failure rate. Companies have their own systems. Most successful companies employ a disciplined plan. Stage 1: Concept development (Brainstorming summary and project title and concept description, Market justification, Product description including potential ingredients and manufacturing, Proposed product development plan) Stage 2: Technical Development (Product formula/manufacturing steps, Detailed costs and potential ingredient suppliers, Prototype of product, Nutrition label, More detailed process flow diagram like for making the product commercially in pilot or large scale quantities, Regulatory aspects of proposed product, including food safety considerations that will be addressed in phase 3) Stage 3: Commercialization (Final formula(s) and manufacturing flow diagrams, and quality and safety program description, Packaging materials, pricing and equipment, Sensory and/or marketing test, Conclusions and justification for launch/no launch

Virus and bacteria and the difference between the two

Virus: Even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus Bacteria: Single-celled microorganisms that thrive in many different types of environments. Some varieties live in extremes of cold or heat. Others make their home in people's intestines, where they help digest food. Most bacteria cause no harm to people, but there are exceptions

Fish toxins in food

Bacteria act on compounds in the fish, releasing histamine Ciguatera fish poisoning: causes nausea, vomiting, diarrhea, muscle weakness, joint aches, headache, dizziness, and low blood pressure. A characteristic symptom is "hot-cold reversal"; hot items feel cold and cold items feel hot. Symptoms may begin within 15 minutes to 24 hours after eating affected fish

Description of alcohol in relation to nutrients

a. It does not support growth and development. Its metabolites are toxic and need to be removed from the body, the primary site for this is the liver. b. It may not provide nutrients, but it does provide energy, at 7 kilocalories of energy in each gram. . Alcoholics often eat poorly, limiting their supply of essential nutrients and affecting both energy supply and structure maintenance. Furthermore, alcohol interferes with the nutritional process by affecting digestion, storage, utilization, and excretion of nutrients

Digestion, absorption and metabolism of alcohol

a. small amount of alcohol is not metabolized and is excreted through sweat, saliva, urine, and the breath. In the liver an enzyme known as alcohol dehydrogenase (ADH) converts alcohol to acetaldehyde. ... It must be remembered that alcohol is a lipid that is water soluble, so it can be digested soon after absorption After alcohol is swallowed, it is absorbed primarily from the small intestine into the veins that collect blood from the stomach and bowels and from the portal vein, which leads to the liver. From there it is carried to the liver, where it is exposed to enzymes and metabolized.

Liver diseases induced by excessive alcohol consumption

Many heavy drinkers will progress from fatty liver disease to alcoholic hepatitis to alcoholic cirrhosis over time. Others may have alcoholic hepatitis but never have symptoms. Additionally, alcohol consumption may worsen liver injury caused by non-alcoholic liver diseases such as chronic hepatitis C

Alcohol and coffee - effects on a human health and body and in relation to one another

As a stimulant, caffeine jazzes up your whole body, increasing blood pressure, heart rate and, in some cases, causing heart palpitations and an irregular heartbeat. Caffeine also leads to headaches, jitteriness, agitation, stomach problems and abnormal breathing. It's the equivalent of an adrenaline rush, Lipshultz said. mixing is bad raise and lower heart rate at the same time

What is a diuretic and its effect on a body?

For high blood pressure, diuretics, commonly known as "water pills," help your body get rid of unneeded water and salt through the urine. Getting rid of excess salt and fluid helps lower blood pressure and can make it easier for your heart to pump

(Bacteria) Can be found on pretty muh any food product that you are likely to consume. Source is from raw produce such as melons, tomatoes, alfalfa sprouts, and orange juice. Raw meats, poultry, milk, and other dairy products, shrimp, frog legs, yeast, coconut, pasta, and chocolate are most frequently involved. Individuals carrying this organism but exhibiting no symptoms of illness could contaminate produce due to poor hygiene practices.

Hemolytic Uremic Syndrome

An illness that is derived from the bacteria E.Coli.

Listeria monocytogenes

The cause of an outbreak of a food-borne illness was traced to unpasteurized milk; symptoms included fever, nausea, headache. The likely source is:

Clostridium botulinum

produces preformed, heat-labile toxin that inhibits ACh release at the NMJ, causing botulism (flaccid paralysis). In adults, dz is caused by ingestion of preformed toxin. In babies, ingestion of bacterial spores in honey causes dz (floppy baby syndrome). BOTulinum is from bad BOTtles of food and honey.

Accumulate in the environment and the human body

GRAS

Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements.

HACCP

Hazard Analysis and Critical Control Points or is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe, and designs measurements to reduce these risks to a safe level. Program that has established the foundation for others in managing food production to reduce the chances of food borne outbreak. Set forth the seven principles: 1. Conduct a hazard analysis to identify potential hazards that could occur in the food production process. 2. Identify the critical control points (CCPS), the points I the process where the potential hazards could occur and can be prevented hazards could occur and can be prevented and/or controlled 3. Establish critical limits for preventive measures associated with each CCP. A critical limit is as criterion that must be met for each CCP. (Where appropriate critical limits may reflect relevant current regulations) 4. Establish CCP monitoring requirements to ensure that each CCP stays within its limit. Monitoring may require materials or devices (such as thermometers) to measure or otherwise evaluate the process at CCPs. 5. Establish corrective actions if monitoring determines that a CCP is not within the established limits. 6. Establish effective record-keeping procedures that document that the system is working properly Guidelines to promote food safety at every step of food production: the farm, storage, retail stores, restaurants, and consumers.

Sustainability

A set of policies or practices by which societies can ensure that the people of the future have the same access to resources and thus the same economic and environmental opportunities as people living today. 3 major concepts: ecology, economy, and health.

Caffeine and alcohol in breast milk and complementary food recommendations

Breast milk can transfer caffeine from mother to baby, high caffeine intake in nursing can make babies irritable. Small amounts of caffeine and alcohol may be tolerated as baby grows, but daily intake is not recommended. It is recommended that if these are in the system, that they pump first to rid the milk of them, and then breast feed. Avoid milk, peanuts, eggs, and wheat.

In what way microorganisms, freezing, and heating, and salt affect food – flavors, texture, etc.

Heating (Pasteurization) is when food is heated to temperature below boiling point that is high enough to kill any bacteria that would spoil the food. Examples are things such as milk, wine, etc. It keeps the food safe while maintaining the same taste and texture. Salting (Adding of Nitrates and Nitrites) is used in the curing and smoking process that have been used for centuries to preserve meats. It is part of what gives foods such as ham, hot dogs, and lunch meats their pinkish color. When food is salted, it removes much of the moisture and deters bacterial growth. Microorganisms work to spoil and make food dangerous, the other methods are some of the processes used to enhance preservation in food manufacturing.

Agencies/organizations in U.S. and Florida (FL) responsible for safety and production of food.

United States Department of Agriculture (USDA) – Oversee the production of meat and dairy products Florida Department of Agriculture and Consumer Services (FDACS) – Oversee food products that don’t cross the state line, Handle food that is produced and distributed locally, unlike state-line overseers.

Categories and characteristics of new food products

Line Extension (A variant of an established product, often a new flavor in a line of products) Re-positioned products (The re-purposing of a product, for example the many uses of baking soda. usually requires R&D, new packaging, new marketing strategies, possibly legal review) New for of existing product (Consumers must perceive an added value of the new form, for example Rice Roni to Rice Roni express), Reformulation (Often labeled "new and improved", may be in response to ingredient cost issues, consumer complaints, regulatory issues, problems with getting an ingredient, sometimes there is marketing change but most of the time goal is for consumer to not notice a change) New packaging (Range of R&D effort depends on packaging novelty, Distribution remains same, however will probably require packaging line equipment changes, Recent trend in past 10 years has been towards single-serve portions also transition from glass to plastic) Innovative products (Innovation implies a clever improvement of something already in existence, There is a fairly high degree of risk/expense involved, especially to those who are the trailblazers in a category, May or may not require a lot of R&D; will probably require a lot of marketing and sales support.Example: Baby cut carrots) Creative products (Create implies bringing something completely new into existence, Usually require huge investments in R&D, legal/patents, manufacturing lines, high risk high reward, truly creative products are rare, Often creative foods are ingredients that are then used in other foods, Might even be GMOs, example is a refined sugar for "light" drinks) -Convenience, Shopping, Specialty

Customer and consumer and marketplace

Customer – The purchaser, the one who buys in the marketplace. The gatekeeper Consumer – Uses what is purchased by the customer (the of course can be the same person), consumers can influence the customer (children telling parents what they want to eat) Markets – A market is conceptual (not a place), represents a need that marketers hope to turn into a want, that is an opportunity to sell, example: the market for organic foods) Marketplace – physical retail outlet where products are sold. for example: super and farmer’s markets, vending machine, On-line provisioners)

Virus and bacteria and the difference between the two

Virus: Even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can’t survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus Bacteria: Single-celled microorganisms that thrive in many different types of environments.

Description of alcohol in relation to nutrients

a. It does not support growth and development. Its metabolites are toxic and need to be removed from the body, the primary site for this is the liver. b. It may not provide nutrients, but it does provide energy, at 7 kilocalories of energy in each gram. . Alcoholics often eat poorly, limiting their supply of essential nutrients and affecting both energy supply and structure maintenance. Furthermore, alcohol interferes with the nutritional process by affecting digestion, storage, utilization, and excretion of nutrients

Digestion, absorption and metabolism of alcohol

a. small amount of alcohol is not metabolized and is excreted through sweat, saliva, urine, and the breath. In the liver an enzyme known as alcohol dehydrogenase (ADH) converts alcohol to acetaldehyde. … It must be remembered that alcohol is a lipid that is water soluble, so it can be digested soon after absorption After alcohol is swallowed, it is absorbed primarily from the small intestine into the veins that collect blood from the stomach and bowels and from the portal vein, which leads to the liver. From there it is carried to the liver, where it is exposed to enzymes and metabolized.

Liver diseases induced by excessive alcohol consumption

Many heavy drinkers will progress from fatty liver disease to alcoholic hepatitis to alcoholic cirrhosis over time. Others may have alcoholic hepatitis but never have symptoms. Additionally, alcohol consumption may worsen liver injury caused by non-alcoholic liver diseases such as chronic hepatitis C

Alcohol and coffee – effects on a human health and body and in relation to one another

As a stimulant, caffeine jazzes up your whole body, increasing blood pressure, heart rate and, in some cases, causing heart palpitations and an irregular heartbeat. Caffeine also leads to headaches, jitteriness, agitation, stomach problems and abnormal breathing. It’s the equivalent of an adrenaline rush, Lipshultz said. mixing is bad raise and lower heart rate at the same time

What is a diuretic and its effect on a body?
