Why I’m Eating Like My Life Depends on It (Because It Might)

In 2020, my mother passed away from kidney disease. She refused to go on a dialysis machine. I found out a few days ago that her sister, now 80, has stage-4 kidney disease. My aunt doesn’t drink or smoke, but her doctor told her that age can do its job on the kidneys and will give her medication and a diet to slow down the disease’s progression. 

I assume I may have a genetic predisposition for tired kidneys, so at 63, I’m looking to make some preventative dietary changes. I’m going to watch my potassium, phosphates, and sodium. I’m going to cut down on dairy, nuts, nut butters, sweets, diet sodas, canned fish, meat and such. I’m going to keep my creatine at 3 grams a day. Being overweight, having high sugar levels, high cholesterol, and high blood pressure are all bad for the kidneys, so my diet has to keep those areas under control. I remember Doctor Peter Attia writing in his book Outlive: The Science and Art of Longevity that having advanced kidney disease presents a shorter lifespan diagnosis than stage-4 cancer, so I feel motivated to be diligent. My diet now looks like this:

Breakfast: I’ll rotate 5 breakfast grains in which I will measure exactly one-fourth cup of one of the following: 1. steel-cut oatmeal, 2. quinoa, 3. buckwheat groats, 4. bulgur, and 5. hulled or foxtail millet (11-12 grams of protein) with half a cup of Greek plain yogurt, chia seeds, walnuts, plain soy milk, phosphate-free protein powder, berries, and coffee.

Lunch: Salad with 20 grams of protein tempeh, rinsed from a can or cooked beans or salmon with balsamic vinegar, herbs and spices, half cup of soy milk, berries or small tangerine. 

Post-nap Afternoon Snack: One cup of plain Greek yogurt with phosphate-free protein powder, or no powder at all, and berries. 

Dinner: Vegetables, protein of some kind, including braised tofu, and a small apple. If I want a vegan dinner, I can make a mixture of rice or quinoa with black beans, tofu or tempeh, and a cup of coconut milk. 

Between meals: No more diet soda of any kind, only water, herbal tea, and soda water.
