yeah, TOO MUCH protein can be very bad for you. I too believe that its bad for your kidneys (believe I saw it on the telly). Afterall, to much of a good thing is a bad thing, and to much calcium is bad for you, and calcium makes you stronger. best in moderation

You can have soyabeans which is the highest nutritive food out which is foung in recent research works.
Consume it daily you would really be very health all throught out your life.

There are not [proteins] really good when you are working out in the gymnasium, for instance.
At first stage, they give you muscles , so your body looks good. But, when you become older, and you are not working out anymore. Your muscles will kind of destroyed, it will seem like they are filled with water, so they will become soft and fat which will come down.

This is what I heard about still today.

Do not use chemicals, they will reveal themselves in the far future.!!!

I would have to say that if you are eating 3 egg sandwiches/day and that's it, you should try to switch it up and add more variety. Not only of the other food groups, but of different kinds of protein as well. Not all proteins are built the same, and you may be missing out on some very important Amino Acids in your diet. Not only that, but eggs are probably the worst form of protein you could eat, considering the fact that they have so much cholesterol... maybe if you wanted to keep eating eggs, you could alternate with egg beaters too, since they have less bad stuff. But you should also try to eat meats and beans for protein. Don't forget too that you should be consuming plenty of dairy, and you could use things like yogurt and cheese to boost your protein intake as well... If you are trying to keep a high protein diet, a good rule of thumb is that you should eat about 1 - 1.5 grams of protein/lb of body weight. This is recommended for people who are trying to bulk up thru weight training or strenuous exercise, so if you aren't doing that you should probably stop.

As far as I know from biology class, two eggs per day for an adult is enough to absorb protein. For more, one will be exposed to a high risk of cholesterol-caused chain diseases like coronary heart disease, arteriosclerosis.

As the basic foundations of protein, amino acid counts. Among all the eighteen kinds of indispensable amino acid which can not be produced inner our body, there might be some kinds of amino acid that you cannot obtain merely from eggs. Thus a lot of other various kinds of food is necessary for you, taking your future health condition into consideration, including those can aid to produce decompose into indispensable amino acid through the inner metabolism.

For more detailed information about the amino acids, you can refer to some professional books or your doctor. There you can get a more nutritious diet suggestion than now. For the long run, you'd better pay more attention to your variety and nutrition of your absorption.

The amount of protein you need in your diet depends on your weight, age and health. As a rough guide, the recommended dietary intake (RDI) for protein (measured in grams per kilogram of bodyweight) is:
0.75g/kg for adult women
0.84g/kg for adult men
Around 1g/kg for pregnant and breastfeeding women, and for men and women over 70 years.
So, for example, a 75kg adult male would need 63g of protein per day.

The needs of children and adolescents also vary according to their age and weight. A full list of recommendations for dietary protein is available from the Australian Nutrient Reference Values (NRVs) website.

Most Australians eat far more protein than they actually need, so deficiencies are rare.

Sources of protein
Some sources of dietary protein include:
Meat, poultry and fish
Eggs
Dairy products
Seeds and nuts
Beans and lentils
Soy products
Grains, especially wheat and less so rice, barley and corn.
To analyse the association between macronutrient intake and body mass index (BMI). DESIGN: A series of hospital-based case-control studies. SETTINGS: Selected teaching and general hospitals in several Italian regions. SUBJECTS: A total of 6619 subjects from the comparison groups of the case-control studies were included in the analysis. METHODS: We obtained data from a validated 78-item food-frequency questionnaire submitted between 1991 and 2002. For various macronutrients, the partial regression coefficient (variation of BMI (kg m(-2)) per 100 kcal increment of energy intake) was derived from multiple linear regression models, after allowance for age, study centre, education, smoking habits, number of eating episodes and mutual adjustment for macronutrients. RESULTS: BMI was directly associated with protein intake among women only (beta = 0.68) and with unsaturated fats in both genders (for monounsaturated fats beta = 0.27 for men and 0.26 for women; for polyunsaturated fats beta = 0.27 for men and 0.54 for women), and inversely related to carbohydrates (beta = -0.05 for men and -0.21 for women) and number of eating episodes in both genders (beta = -0.42 for men and -0.61 for women) and to saturated fats among women only (beta = -0.57). CONCLUSIONS: These results confirm and provide convincing evidence that, after allowance for selected covariates including total energy intake, a protein-rich diet is not inversely related to BMI, and a carbohydrate-rich diet is not directly related to BMI.

Only eatting egg sandwiches is definitely not healthy for you. You may feel fine now but you are missing tons of other nutrients other foods contain like antioxidants, fiber, calcium, etc. that are contained in other foods. Look at the food pyramid and you will see all the groups you are missing. These will affect your health in the long term so you may or may not notice it yet in your life. Also, eggs have lots of cholestorol and that is why lots of people do not / can not eat them in that quanity since they have to worry about having high cholestrol. I would recommend you eat different products and types of food and maybe limit yourself to no more than 1 egg sandwich a day and probably less than that.

Everything in excess is bad, I think its ok as long as you dont eat them every day. Take some breaks from eating eggs, I mean, you can have hotcakes or cereal for breakfast or maybe a ham sandwich.
