Hello Sir! It is not the vegetarians that have much difficulty getting adequate protein, but the vegans that need to be meticulate about their diet and be more concerned about certain nutrients and protein. A wide variety of foods can provide adequate protein on a vegetarian diet. For protein, the general recommendation is no lower than .8g/kg if not athletic and engaged in fitness activities. So convert pounds to kg. by pounds: by dividing pounds by 2.2 = kg. Protein supplements are not generally needed but if you make that choice try to choose an isolated whey based protein, lactose free, no added creatine Personnally, I use the Pure Encapsulation line of protein supplements, but they are available only by mail order. If you decide to implement a fitness program, please feel free to come to my specialist portal, ask for me and I will help you develop one. For right now, please check the following potential nutritional concerns for active vegetarians: 1.Low zinc common 2.Low iron common 3.Low iodine 4.Low copper 5.Low vitamin D,selenium,magnesium,calcium possibly Inadequate amounts of energy and carbohydrate increases protein needs. Protein needs increase with endurance athletes to 1.2-1.4 g/kg and fluid needs increase. Good vegetarian sources of protein include: cheese (8 gm. per ounce); milk 8gm per cup; protein powder 15-21 g per scoop; bread 2-3 g per serving; tempeh 31 g per cup; yogurt 8 gm per cup; quinoa 11 g per cup; tofu firm is 20 g per cup. So, many vegetarians get enough protein and don t realize it. Try doing the math and see if you really need a protein powder. If you need help picking one out you can see what is available in your area, send me the names and I will look them up if they are available to me on my database. It has been so nice chatting with you. I think you have made a good dietary choice!Respectfully yours, Kathryn Shattler, MS,RDN
