(JUST RELEASED!!!!!)
What is Carcinogenesis? - CORRECT ANSWER-The process of
developing cancer from a normal cell
How long does it take to develop aggressive cancer? - CORRECT
ANSWER-Decades
What is mutagenesis? - CORRECT ANSWER-Mutagenisis= genetic
mutations (aka "initiation")
What is mitogensis? - CORRECT ANSWER-Mitogensis= process of cell
division (aks "promotion" that increases the chance of cells
becoming mutated)
How can we prevent cancer? - CORRECT ANSWER-We want to slow
down the genetic damage and/or slow down cell division
What is the multi-hit model? - CORRECT ANSWER-It is when cancer
exhibits many mutations in genes related to controlling
proliferation (the rapid reproduction of a cell)
,How does one cell accumulate many mutations? - CORRECT
ANSWER-A cell does this by growth advantage and clonal
expansion of cells with initial mutations. The daughter cells
then become targets of a new mutation.
Why has their been a reduction of cancer in history? - CORRECT
ANSWER-because of dietary factors and government regulations
What has a come as a result of reducing gastric, cervical, and
lung cancer - CORRECT ANSWER-it has led to the reduction of many
other cancers thanks to nutrition and research
What are some recommendations from govt - CORRECT ANSWER-
Eating more fruits and vegetables, limits on nitrites and
enforcing farms to have electricity and refrigerators to keep
produce fresh
What helps prevent cervical cancer? - CORRECT ANSWER-A pap
smear
What are lessons from cancer successes for nutrition? - CORRECT
ANSWER-Early prevention is MOST effective.
Identify and remove more carcinogenesis like e-cigs.
Monitor progression.
What are some Carcinogenic Mechanisms of Nutrients - CORRECT
ANSWER-Some foods creating free radicals that causes genetic
damage and increases cell division by driving growth stimulus.
,What are examples of Dietary Carcinogens (Mutagens) - CORRECT
ANSWER-Heterocyclic amines (found in cooking meat, poultry,
and fish)
Nitrosamines (found in cured meats and high temp cooking)
Aflatoxin (produced by two types of mold)
How are mutagens formed? - CORRECT ANSWER-Mutagens are
formed during high temp. Cooking that results in chemical
molecules that damage DNA
What can be a tumor promoter? - CORRECT ANSWER-Anything that
increases the proliferation rate of epithelial cells .
Like estrogen or insulin
What does insulin stimulate ? - CORRECT ANSWER-Insulin
stimulates the proliferation and growth of many cell types
What are some Dietary Chemopreventives? - CORRECT ANSWER-
Vegetables (broccoli, cabbage, brussel sprouts, cauliflower)
Soy products (flax seeds, legumes, red clover, fruits, veggies)
Tea
What are some mechanisms in which a nutrient leads to
carcinogenesis? - CORRECT ANSWER-Increasing cell proliferation,
binding DNA and forming a DNA-adduct, and generating free
radicals
, Parathyroid hormone is released when: - CORRECT ANSWER-Blood
calcium level decreases
Common problems found in the elderly include: - CORRECT
ANSWER-Insufficient calorie intake, dehydration
What is bone made up of? - CORRECT ANSWER-Bone is composed of
collagen matrix and calcium + phosphate
What is calcium impacted by? - CORRECT ANSWER-Nutrition
impacts calcium in the body
What body part excretes calcium? - CORRECT ANSWER-Kidney
What can a Vit D deficiency lead to - CORRECT ANSWER-soft
bones/rickets
due to inadequate calcification of bone
What is osteoperosis? - CORRECT ANSWER-Osteoporosis is the most
common bone disease. It reflects the reduction of bone mass
What are the risk factors for osteoperosis? - CORRECT ANSWER-Age
and gender. Women are more likley to get it because they
typically weigh less.
What function does calcium play in our body - CORRECT ANSWER--
Plays a role in protein structure and action
-Involved in interactions in muscle
