I've read about the alkaline/acid balance but I don't really take that into consideration when determining my dietary needs. I just eat whole, healthy foods and try to balance my nutritional needs.
So, all of this is probably a bit out there to many people but I'll share it just in case it might be helpful in some way...
I follow a gluten free/dairy free diet. I am sensitive to dairy so getting my calcium needs filled are a little more challenging. For breakfast I eat cooked collards along with a protein, etc, which gives me over 300 mg to start my day. Some other high calcium foods I include are canned salmon with the bones (they are very soft and can be mixed right in), sardines with bones, tofu (must be coagulated with calcium sulfate) and a tblsp of blackstrap molasses (1 Tblsp has 10%) mixed into my cocoa drink with collagen. I might also take a spoonful of black sesame butter/tahini. It has about 35% of your daily calcium in 2 tblsp so I take what I need like a spoonful of medicine. It is high in calories and fat (good fats) but I'd rather take food than a pill. I drink some herbal teas that are high in mineral content like nettles, peppermint, red clover, horsetail. I also enter my daily food intake on cronometer.com so that I can track my nutrition and make sure I've met my needs all around. I've done it for so long that I generally don't need to do it daily anymore. When I fall short of meeting my calcium intake, I take a supplement as needed. So overall, that's the diet I follow. I'm sure these choices are not for everyone but I I really enjoy eating healthfully and knowing I'm doing all I can naturally in conjunction with whatever I need to do medically.
