Hi well I will say that if a person chooses to eat healthy now they may avoid a lot of needless suffering later if that helps. They will be less likely to have a heart attacks or problems with energy and shortness of breath or weird palpitations or pains in the chest. They would be less likely to have diabetes with blood sugar difficulties, yeast infections daily or 4 times a day finger sticks and ulcers in the legs. They would be less likely to suffer cancer and less likely to suffer with high blood pressure or strokes.
There are some nice recipe books that may be helpful with nice vegetarian food without meat, cheese or fattening things that may help and be quite tasty. Even some of the desserts can be made with fruit juice and less sugar but be quite nice. ( fruits should not be eaten with vegetables though and can be for a different meal) If a person is in a hurry they can use the crockpot and throw a couple vegetable stew packs in there from the frozen food section some tasty seasonings and they will be ready for the thermos in the morning so they can be had for lunch. Of course beans take a few minutes to sort but they are also healthy and can be be done overnight. Frozen fruit packages of various types can be cooked with a very small amount of water and eaten with whole wheat bread.
I hope this gives a nice healthy variation in the diet.
