Yes, loads of people/diets believe that legumes are a healthy source of protein, which they are, but only a moderate amount. You can get more protein, however, from a cup of cottage cheese. They are a good source of potassium and magnesium which is a good thing. Most of us are low on magnesium so that is a good thing.

However they are PACKED with carbs and most people get too many carbs as it is, so if it is the protein that you are after, why not go for a couple of ounces of meat instead?

It sounds like you do take the appropriate care in preparing them (soaking them, etc), but consider why they need to be soaked:

They are loaded with lectins--a low grade toxin.

Have a read of this:

There are worse things to eat for sure (grains) but they aren't really the superfood that conventional wisdom has people believing.

Hello Stamatia
I had posted you a long reply but when I checked just now I saw it had not got uploaded. I do apologise.
You are right, many Greeks are overweight, even obese, but I think it is because they are not following the traditional Mediterranean diet any more. City dwellers in particular eat meat daily, cook with dairy cream and trans-fat laden shortenings (Fytini, Vitam), use seed oils for frying (and there's a lot of frying) because they are cheaper than olive oil. Frozen meals and packaged "convenience foods" have overtaken the supermarket shelves, fast food outlets abound and if you walk the streets in the centre every third person is munching while walking, whereas in the evenings you run the risk of being run over by an army of motorbikes delivering souvlakis and pizzas. Very few people still observe the abstinence from meat and dairy on every Wednesday and Friday of the year, the 40 days of Lent before Christmas as well as Easter, before 15th August and the numerous other Orthodox days of abstinence--even my mother-in-law who is of the old school only fasts during Holy Week. Probably only a few villagers on Crete still climb the mountains to gather horta and snails and get some exercise along the way. You are right, Greeks have the highest per capita consumption of cheese in Europe. But it's not all bad, they also have the highest consumption of dried beans in Europe and, of course, they top the world in olive oil per capita. This may offset the highest level of smokers in Europe (for women, I think the men come second). I am a great believer in olive oil. I use it for all my cooking, even much of my baking. A little goes a long way. When I cook beans, for example, I don't use oil during the cooking, but we each add a little to our plates so it's raw and retains its vitamins and full flavour. I've invented my own Bisquick clone recipe with olive oil. If I fry it's in olive oil. I also use real butter in baking for special occasions, e.g. kourabiedhes--but they are just once a year for Christmas. I don't have any margarines, shortenings or seed oils in the house.
I love all kinds of greens too, though I don't eat them as often as I would like to--I have a bad back and have stopped going to the weekly farmers' market, so I have to rely on Husband to bring our food from the supermarket.
Bravo for doing so well on the Fuhrman diet. I tried it a couple of years ago but I wasn't able to last the distance. You've inspired me to give it another go--I have the book.
Best wishes
Sunny
