Potato
★★★★★
I suppose I shouldn't be surprised. A baked potato is often a first food that I offer to a child who has been sick. It goes down easily and provides some calories and nutrients without being too heavy.
My favorite way to prepare potatoes, if I want something a little more fancy than a baked potato, is to cube the potatoes and toss with olive oil and salt and pepper and bake at 400 till they are beginning to crisp on the outside but are still soft on the inside. When I make these, no matter how many I make, they all get eaten. (And make amazing leftovers for breakfast with some eggs. :)) I am going to make some for my daughter in law tomorrow evening.
Molybdenum
★★★★★
So to apply this to morning sickness, eat more legumes/liver/cream/barley/oats/nuts and avoid sulfites (all over the place in processed foods) and nitrites. If you want to try taking molybdenum as a supplement, talk to your OB/GYN first because pregnancy is no time to experiment with large, chronic doses of anything.
