Peanut butter and walnuts (1 spoon)

Confirm the pattern with repeated measurements: check glucose before eating and again at 30, 60, 90, and 120 minutes, since sensor lag or compression can sometimes look like a sudden drop.

Reduce the portion size of peanut butter and walnuts, especially if the drop follows a larger, high-fat serving; try one food at a time to identify whether either is the trigger.

Choose peanut butter containing only peanuts and salt, without added sugar, syrups, or highly refined oils, and avoid sweetened nut spreads.

Eat the nuts or peanut butter as part of a balanced meal rather than alone; pair a modest portion with plain Greek yogurt, eggs, tofu, or non-starchy vegetables such as cucumber or leafy greens.

Avoid combining them with alcohol, prolonged fasting, or intense exercise, as these can make a glucose decline more likely in some people.

If you have symptoms of low glucose, recurrent readings below your personal target, use glucose-lowering medication, or have diabetes, discuss the pattern promptly with your clinician; seek urgent care for severe confusion, fainting, or inability to safely swallow.
