Is it dangerous for a vegan to introduce animal protein to diet too quickly?

My sister has, by her own choice, been vegetarian since 8yrs old. She is now 20. She went vegan I think 2 years ago. Now she has chosen to join the Naval reserve and starts boot camp Monday. On her own she is able to make life changes to assure a healthy vegan life style. Boot Camp does not make any room for life style choices. She may be able to consist on vegetables and animal products, thereby maintaining a vegetarian diet, but in order to consume enough energy, she will not be able to to consist on vegan diet. She has not even started to reintroduce animal products/proteins. Will it be dangerous for her to add them in so quickly?

remember, we are talking boot camp here!!! no she can't chose things like healthy fats and salad toppings.

Oh yes. When your body hasnt had something its "meant" to have in 12 years, introducing it back in fast will cause some problems. These meat products are foreign to her body so it's not gonna know how to react to them; it'll usually just come back out one end...not pleasently though. She should just introduce it slowly, in small portions. She may have to put in an extra effort in the beginning to overcome a little lack of energy but, its better than making runs to the bathroom every 5 minutes. Give it a couple weeks, and she should be fine.

Remind her that any drastic change may ultimately hurt her, so introduce the new foods slowly and in moderation and after a few days, she'll be ready for the protein.

Try to read this post about Salad?

Salads are certainly healthy meals, especially if you can add some dark leafy greens such as spinach or kale. According to Chinese medicine, leafy greens help clean the blood, and since the blood pulsates through our whole body, that is a very good thing. My personal favorite reason for eating greens is that they help lift my mood. The world always appears to be a lighter, happier place after I eat a large and satisfying meal of dark, leafy greens.

But for many of us, a salad simply does not offer enough calories to stabilize the blood sugar between lunch and an afternoon snack. If you are a salad eater who loses focus, gets sleepy, and craves sugar one or two hours after lunch, I鈥檓 talking to you. This is not the rule across the board, but many people need to have three components in their salads in order to feel satisfied and 鈥渇ull鈥? healthy protein, good fat and a whole-grain complex carbohydrate, bean or legume.

Here are some suggestions to make your next salad more satisfying:

1. Add good fats: olive oil, olives, avocados, nuts. Fats make food actually taste good and alert your body that you are eating. They also make you feel fuller, longer and keep your blood sugar levels stable, so you can think properly during that 4:00 meeting.

2. Add enough healthy protein: lean meats like chicken and turkey, eggs, beans, soybeans. If you are someone who gets incredibly hungry one hour after eating a salad then you may need to add two servings of protein. Play with your salads and see what your body likes best.

3. Add a whole-grain complex carbohydrate: This part is tricky. Often the only really healthy complex carbohydrates are beans and legumes. These are a great addition to a salad. But if you feel like you need more, then keep a stash of whole-grain crackers or pita breads at your desk to munch on with your salad. I like the AK-MAK sesame crackers best. Just make sure the first ingredient on the list says 100% whole-grain or whole wheat.
