Beware the Mango and peaches. Tropical fruit especially canned in syrup are a no-no for most of us. Frozen berries such as summer fruits are possibly a better bet and keep well in the freezer. Yogurt may be an idea instead of milk, but avoid those ones with cartoon characters in their advertising.
Oats as has been discussed are problematic for most T2D. The LC diet section has recipes for low-carb porridges based on seeds rather than grains. If you must have oats go for the old-fashioned milled oats rather than the modern 4 minute processed pap. Cuppa porridge might be more convenient but has very little nutrition in the way of fibre and vitamins. PS as a follow on thought, smoothies are not very good for us either due to the overprocessing involved.
Testing at 2hr and 4 hr should be adequate to catch the protein/ pizza effect for most meals. The spike at 1 hr is not really of interest unless it is still there at 2hrs.
