Question

Liam is a 17-year-old male who is being seen by his family physician for his annual physical examination. Liam’s sexual maturation rating is estimated to be 3. He weighs 114 lbs and stands 5’6” tall.

When he was 16 y.o., his height was 5’5” and weight was 106 lbs.  

At 15 y.o., Liam was 5’3” tall and weighed 98lbs.  

During the visit, Liam reports that he has been experimenting with a vegan diet since his visit last year. He explains that he thinks it is a healthier way to eat and states that he avoids milk, beef, and pork eats poultry or fish once every two weeks and eats cheese 3-4x/wk. Breakfast is usually cold cereal with almond milk because he heard that was a healthy milk alternative. He likes pasta, pizza, and salad, which he eats almost every day.  

For exercise, he runs 3 miles 2x/wk, plays basketball with friends after school 3x/wk for an hour, and lifts weights in his garage for 45 min 5x/wk.  

He says he would like to gain muscle and grow taller.  

3. What clarifying questions would you like to ask Liam about his current behaviors? List 3.

4. If there is protein a concern in Liam’s diet, why? Estimate his RDA and use evidence to support your position.

5. Given Liam’s diet and exercise patterns, which dietary components may he be deficient in? For each dietary component, list possible food sources that are appropriate for his current eating pattern.

6. There are both health benefits and costs of eating mostly plants. How might his current way of eating affect Liam’s growth and maturation?

7. Is it necessary to assess Liam for the presence of an eating disorder? Provide support for your answer.

Answer 1

3)1. If he is started vegan diet due to his health concerns then why he is not avoiding junk foods like pizza?

2.about his changes in behaviour, voice tones?

3. If he is too much smaller than his friends?

4. What is the reason for starting a vegan diet ?

4)yes. A vegan diet contains only plants (such as vegetables, grains, nuts and fruits) and foods made from plants.Vegetarians have higher protein requirements because plant proteins are not as well digested and processed by the body as animal proteins, and are not as 'complete' as protein from meat.

The Recommended Dietary Allowance (RDA) for protein is a modest 0.8 grams of protein per kilogram of body weight. The RDA is the amount of a nutrient you need to meet your basic nutritional requirements.

RDA of proteins for loam is around 40grams per day according to his weight.

5.Nutritional concerns regard- ing vegetarian and vegan diets include the intake of protein, omega-3 fatty acids, vitamins B12 and D, calcium, iron, zinc, and iodine. These should be included in his diet.

1.Protein::Legumes,
soyfoods, whole grains, nuts, seeds, and some vegetables are
good sources of protein. Soyfoods are unique because they con-
tain good percentages of all of the essential amino acids, with a
similar profile to animal proteins.

2.omega3fatyacide:: flaxseeds, walnuts, canola
oil, and soy are rich with ALA. And marine algae supplements are good for getting these .

6)1.Too little protein can lead to stunted growth while too much fibre – another concern in vegan diets – can cause children to feel full too quickly, stopping them getting enough of other nutrients in their food.

7.)it is not needed

)

2.Legume protein sources can increase risk of leaky gut.

3.Soy protein sources can cause hormone disruptions, including estrogen and thyroid hormone

4.Risk of anemia due to a lack of heme iron.
