The real problem, at least one, is poor education about nutrition. Mothers who rear their children correctly and care for their families know how to cook and serve healthy food. So the real question is where do you find these women? I am going to get hell for this but I am prepared.
And that a meal once in a while can be only semi healthy like on holidays. Thanksgiving thru New Years are the worst eating seasons. Put up some good recipes for traditional American meals for those days.
I make Turkey, gravy, mashed potatoes, green beans or frozen corn. And use my bread oven to make bread. Cranberry sauce. Turkey is cooked in one of those oven bags, so you don't have to baste, make my gravy out of the broth from the bird after the oil has been drained off.
Sweet Potato pie with pumpkin pie spice, no one knows the difference between it and pumpkin, and they get better vitamins and minerals. News Years day is a snack tray with good snacks with a french onion or ranch dip. Cheese, left over turkey, ham, 2 kinds of pickles, olives, and baked potato chips. I completely changed my set in his ways 70+ year old husband's diet and he never complained. I just had to relearn to cook healthy for his cholesterol control. Since I do the shopping I control what comes into the house. He still gets his meat and potatoes, and what veggies/fruit he will eat. And he never noticed his snacks became portioned controlled and low fat, low sodium, low sugar. All he needed was something that said CHOCOLATE. Worse chocoholic than a woman. Dropped his morning banana and dropped his TRIS by 100 pts. Put Blueberries in their place. Now I have him counting out the jelly beans he insist on to make them last for the week. I can't walk the grocery store, so if there is no electric cart, it's grab the skim milk and low sodium bread and get out. BTW if you must have bread make it whole wheat, Kroger brand is lower in sodium than name brands. I've read all the labels. Taste as good too.
There are plenty of us. We’re just old school and out of the mainstream.
