@carbcounter American breakfast cereals in particular (but Canadian ones too) do tend to be unhealthy from a metabolic perspective, e.g. avoiding type-2 diabetes, which is a major risk on prostate-cancer treatment.

Even without added sugar, they're often processed so much that they still have a Glycemic Index (GI). I've actually heard people in the States talk about eating Cheerios as if they were virtuously consuming a health food, instead of eating something just barely better than the sugary cereals.

Shredded Wheat is OK-ish — the only ingredient whole wheat (good), but it's still heavily processed (less good), and still medium/high GI. If you're worried about blood sugar and diabetes, something like muesli or oatmeal made with whole oats (not "quick oats") will do you just fine as a breakfast cereal (low/medium GI). But be careful of portion size, because muesli is dense, so even though the GI is lower, the Glycemic Load (GL) might not be if you eat a large bowl.

Sweetened yoghurt is simply disgusting. I have no idea why people eat that. The sourness is what makes yoghurt or kefir tasty (but that's a different discussion 🤷).

@carbcounterPlain Low fat Greek yoghurt is beneficial with previously frozen Berries-Blue berries, Strawberries etc is what i typically have.
Eggs without the yolk is beneficial for your Kidneys
:Pomegranates, Pumpkin seeds great for the prostate
I have 2 dates in the morning first thing

@carbcounter FWIW: Costco sells a greek yogurt "Kirkland Signature Organic Greek Yogurt" that is non-fat and unsweetened. Two ingredients, non-fat milk and cultures. I've made the switch from what I used to eat.
