The only way to have uneaten live plants in an aquarium is to not have any animals in there with them. Or have all carnivorous animals, in which case, they may eat one another. Carnivores will need to be fed the appropriate foods, such as brine shrimp, blood worms and other prey foods. But if you want a nice community tank with unmolested plants, I would go with good quality artificial "silk" plants. Some of the plastic ones look tacky, but many of the better silk plants (which are really polyester and not silk) look perfectly natural and lifelike. The quality is amazing with some of the more expensive ones. You literally cannot tell them apart from the live specimens just by looking at them.
If you want a variety of fish and live plants, you'll have to accept that some of those plants will serve as snacks for your fish. This is actually good for your fish, as it increases the variety and balance of their diets. They aren't all just getting one kind of food that way.
I would also suggest some floating plants that lay on the water's surface. These are attractive as they cascade down into the water, and they provide additional shelter and security for your fish, who can hide in them. They will also help soak up nitrates along with the substrate plants. Fish can nibble on floating hornwort, elodea or anacharis and if you have a large enough clump of it, it will still last a long time, as it grows back fairly rapidly.
Also, try java moss. That can float, too, but beware: Java moss grows and spreads prolifically, and may become a pest after awhile. It will give your fish plenty to nibble on and they might be less inclined to go for your substrate plants.
Life is a trade-off system. You may have to decide what is more important to you -- a lushly planted tank with few or no fish, or a nice balanced variety of aquatic life.
There's one more benefit to having plants that fish eat: When you go on vacation and you aren't sure if the commercial vacation foods are going to be adequate, the plants will help tide the fish over until you return.
Think about all the pros and cons, and go from there.
