Neither is "SO" much healthier than the other. The entire framing of the question and the popular micro-debates in standard American society are foolish and miss the greater picture of nutrition. We gotta have healthier diets all around. The whole boat. Not just--well, I'm stuffing myself with Big Ruth steaks and packaged grocery enjoyments and pastries, because that's the American way, and
OH BY THE WAY, should I swap this one component for the other?
Cause the little stuff won't make a difference if the boat is full of garbage.
Peanuts are whole. You should eat whole food. Not Planters brand salted toasted peanuts. Not potato chips made from Monsanto Lays McDonalds potatoes that have been ground processed then fried baked salted and artificial flavor enhancements and with TBHQ and preservatives added, in a bag, sitting on a darn shelf.
Fresh plant food,
whole and up from the ground. Roots, fruits, stems, leaves.
Put that body in balance, give it the tools so the highway workers of your body can heal itself. Brain synapses, recovering muscle, clogged arteries, poop in the bowels, spring cleaning. Get that mood up. Get in tune. Get your genitals perky and healthy. The whole shebang.
Yes, peanuts are fatty, so use them as a component. Balanced eating. Need a salad dressing? Need a little fat and flavor in a meal full of fresh veggies? Get those peanuts in. Same with potatoes. Yeah, they are starchy, but in natural form, pair them with a mixed natural meal. We need green leafs, but you feel like you can't survive on only twigs and acorns? So get a complete balance.
No need to defer to packaged artificial forms. Get some potatoes--preferably organic because big farming is a disgrace--boil them, microwave them. No need to put butter or salt. They taste so good as they are. Use that steaming potato starch with fresh green beans, chopped green lettuces. So good.
