Pistachio Nuts (100 G) and Coffee (1 Mug (8 Fl Oz))

Choose plain black coffee or coffee with unsweetened milk; avoid sugar, syrups, sweetened creamers, and flavored add-ins.

Have coffee after or alongside a balanced meal rather than on an empty stomach, especially if caffeine tends to raise your readings.

Keep pistachio portions modest, such as a small handful, and choose plain, unsweetened pistachios rather than honey-roasted or sweetened varieties.

Pair pistachios with protein or fiber-rich foods such as eggs, plain Greek yogurt, chia seeds, or avocado to slow digestion.

Try decaf or half-caf coffee for several days to see whether caffeine is contributing to the rise.

Take a short easy walk after eating and track portions and timing to identify the combination that gives you the steadiest response.
