Hey, why don't you just ask your doctor how many grams you need to eat?  You might already be getting enough, or at least close enough that another glass of something will do the trick.

My additional question would be: how can I get the added protein if I can't use soy products? cozysnana

this thread is awesome.  im a vegan athlete (marathoner/triathlete) so im pretty avid about my nutrition. 

oftentimes vegetarians are concerned they are not getting enough protein.  While it IS good to be concerned about your diet and eat as well as possible, WHO estimates claim 5% of your calories should come from protein, and in the developing world as long as you eat a reasonably balanced diet (i.e. you're not eating grape jelly with a spoon all day) you cant help but reach that number.

cozysnana, i dont know if you're allergic to soy or not, so im going to throw a bunch of suggestions out here, some of which have soy, some don't

first and foremost is seitan and its ilk.  made from wheat its low fat and super high in protein. more over, ist delicious

dont forget that whole grains contain protein as well.  if youre NOT vegan (i am so i cant eat it) barilla plus pasta has 10g protein per 200 kcal serving.

also, just a plain ol' bowl of oatmeal has 5g protein.
i slice of whole grain toast usually has around 3 g. and even veggies like kale have protein content (2g per 80 kcal)

also, the various processed fake lunch meats-yves canadian bacon, the smartlife sliced fake meats etc.  these DO contain soy protein isolate but have more wheat gluten than soy (by volume). per 80 kcal serving they have between 12-18g protein.

for those that CAN eat soy, I'd reccomend adding TVP to dishes.  22g serving (about 70 kcal) has 11g protein and it tastes liek whatever else you're eating.  i like it on top of pasta, in soups, even in my oatmeal!

I don't think I caught you in time for your appointment, but hopefully so!  If not, maybe this'll help next time, if it's still an issue. 

I would ask him targeted questions:

How many grams of protein should I be getting daily?
What other nutrients should I be getting, and in what quantities?
What are good vegan sources for those nutrients? 

Be firm about your commitment to your dietary choices, and take a notebook.  Take notes!  Be ready to be frank and accurate about what you have been eating: if you have been keeping track and can tell him what nutrients you are getting, he should be more able to give on-target suggestions.  Also, he will be pleased to see you planning for your health, and if he cannot suggest vegan alternatives, do ask him for a recommendation for somebody who can help with that part of planning your diet. 

I just noticed that you are 16 years old (don't know how I missed that right there in the first post :) ), growing adolescents may have different protein needs than an adult who is not growing.  This is what my nutrition life-cycle textbook says for your age group (it includes a recommendation based on height as well as weight):

Females 15-18 years old, recommended kcal/day: 2200, recommended grams protein/day: 44

Recommended grams of protein by height: .27g/cm (you are 5'5=165cm) which works out to 44.5g per day for you.

Still well below 120g.

Obviously, soy products are high in protein. Soy-based hot dogs, lunch meat, etc are all great choices. But a diversity of protein sources is best, so keep these things in mind, too:

-Nuts -- full of protein and lots of other nutritious stuff as well, and they can go into all sorts of things: trail mix, baked goods, etc. When I had a nutritionist, she told me to eat walnuts. Peanut butter sandwiches and peanut sauces over stirfry are also good sources of nut protein.

-Whole grains -- whole grains almost always have more protein than their non-whole equivalents. Use brown rice instead of white. Eat whole grain bread and if you bake, try to use half whole wheat flour. Rye flour, teff flour (available in natural foods stores or Ethiopian groceries) and soy flour are also good sources of protein.

-Legumes -- split peas, lentils, pinto beans, and black eyed peas are good, as are several others.

As for calcium, I find supplementation the easiest way to make sure I get enough. 8 out of 10 women aren't getting enough calcium!  Aside from that, there's fortified orange juice or soymilk, molasses (try molasses or gingerbread cookies, a bit of molasses in oatmeal, or if you're ambitious perhaps oatmeal molasses bread), some legumes (soy, white, great northern), kale, and broccoli.

And yes, the amount of protein your doctor is telling you to consume is shocking! I would definitely ask the nutritionist about it. Excessive protein intake is linked to poor calcium absorbtion, so eating too much protein could make it harder for you to get enough calcium.

Beans have been mentioned above, but chickpeas and hummus are both good and tasty protein sources too. I find it helpful to incorporate protein into almost every meal if I can in order to make sure I eat enough during the day (eg. quinoa w/ my oatmeal at breakfast, lentil soup at lunch, tofu at dinner, etc). I often grind up pumpkin or hemp seeds and add them to recipes (mostly smoothies). You could also try yogurt (soy varieties available), texturized vegetable protein, and goji berries, which are packed with all of your amino acids. I also eat protein wraps instead of the regular carb wraps.

In case iron is a problem for you (it is for me, I am petite, female, and athletic), I have started using maca powder. It is a root vegetable and a great source of iron. I heard about it from a vegan at a farmer's market (she also got me into goji berries).

Congrats by the way on getting your health back!
