Some nutritionists are claiming that the secret to long life is to be slightly underweight as an adult. If a person’s weight is related partly to diet, partly to activity level, and partly to genetics, what underlying factors could be at work to generate statistics that support this claim?
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?
Nutrition plays an essential role in supporting fitness and exercise. If you increase your level of physical activity, your need for nutrients and calories will also increase. In addition, the foods you eat before and after you exercise will have an impact on your performance during physical activity and on your recovery afterward.
Perform some library research, and in a 2–3-page paper written in APA format using proper spelling/grammar, address the following:
Describe the importance of pre- and post-exercise nutrition choices. Provide examples of foods that are appropriate selections for each category. be specific: I do not want to see protein and fruit, instead, you could write protein shake with 1 g sugar and one medium banana. Carry this thought thru out your paper.
Explain how foods and nutrients (including fluids and electrolytes) help improve a person's performance during physical activity and their recovery afterward. be specific: I do not want to see protein and fruit,…
