Vitamin A deficiency and blindness are a major problem in 3rd world countries. A program called Golden Rice is helping to prevent this by adding vitamin A to white rice.
How do you feel about genetically modified foods?
Is this an effective and safe way to eliminate malnutrition in the developing world?
Does the cost of genetically modified foods outweigh the benefits? ( need short answer. 30 to 60 words)
The CDC states "The estimated annual medical cost of obesity in the U.S. was $147 billion in 2008; the medical costs for people who are obese were $1,429 higher than those of normal weight."
Question: What would be a good policy that would help align American life away from obesity?
Vegetarian diets are associated with a lower risk of obesity and diabetes as well as other chronic conditions (Marsh, Zeuschner, & Saunders, 2012). Clearly a vegetarian diet can be a healthy one, but can a vegetarian diet lack nutrients? If so, which nutrients may be lacking? How could these nutrients be measured in the body to determine if someone is deficient in them? Are there vegetarian foods that provide these nutrients or would supplementation be necessary? Are there any interactions to be aware of with the supplements that a vegetarian may take?

- Why is it so difficult to tell what makes us healthy or unhealthy? As new research is presented, sometimes earlier recommendations for what foods and activities are considered healthy need to be modified. Should recommendations be followed, knowing that they may change in the future, or should you just ‘go with your gut’ (haha, that was an eating pun)? As more data accumulates and studies are conducted with larger groups people over longer periods of time, are we getting closer to determining what constitutes a healthy lifestyle? Or are individual people variable enough in physiology (inability to metabolize lactose, gluten sensitivity, etc.) and genetics that universal recommendations are unrealistic?arrow_forwardExplain the following phenomena: A. In a survey conducted on the population of men aged 60-75 in Japan, who are fed a traditional, rich Japanese dietIn fish, the percentage of men with cardiovascular disease was found to be small compared to Europe. B. Poor population in Egypt, fed on a low-calorie vegetarian diet, does not suffer from protein deficiencyOr vitamins. C. A person whose gallbladder has been removed from their body is told to refrain from eating high-fat foods. D. A defect in the breakdown of proteins is found in a person in whose stomach the level of acidity was measured 1.6 = pH (the normal value is 3.7) E.

- Why do we gain weight when we eat too many calories?arrow_forwardHere's the question: "Do we know all the essential nutrients (for humans) including the amounts required by humans for healthy nutrition?" What do you think? What is the evidence? What is the difference between "essential nutrients" and "RDI amounts of essential nutrients"? If you were a research scientist how would you prove your hypothesis? We are not asking about "foods" but rather "essential nutrients" - there's a difference!. We are not talking about "therapeutic nutrition" but rather "normal nutrition" "Science doesn't know everything" is not a good answer. "New foods will be discovered" is not a good answer. Your answer should not include herbal medications or drugs or answers like "who knows what we may discover in the future?" or anything about possible discoveries in the Amazonian rain forest!
