Courton, have you tried any of the recipes from Qouirky Jo, Teresa Cutter, Sarah Wilson, Cyndi O'Meara or My New Roots? Google any of them - plenty of healthy blog sites.
There is much debate about what constitutes healthy eating. I personally eat good fats, including coconut, minimal or no added sugars, gluten free, full cream milks and as low additives, preservatives as possible. Also minimal white foods. Add nuts to everything., and my new favourite is raw cocoa powder. I do have a packet of stevia - have used once.
I substitute pears, apples , bananas (not always made into a sauce) for sugars, or I may add some dates or a small amount of honey.
I may grind dried chick peas, brown rice or oats (or a combination) instead of flour. Also I sometimes add a can of drained legumes instead of flour. Sometimes add chia gel (1 tabs chia with 3 tabs water, soaked until gel consistency) to the mix to bind together or use instead of eggs.
As I freeze any leftovers immediately, I have no problems with cakes or biscuits becoming stale.
Goo luck with the cooking and have fun
