The Science
This food is high in sugar (+12% DV) and refined carbohydrates (+20% DV), which can cause blood sugar spikes and disrupt sleep quality by interfering with melatonin production. It also contains significant sodium (+18% DV), which may increase nighttime urination and disturb sleep. While it provides some magnesium (+7% DV) that supports relaxation, the overall high glycemic load and sugar content outweigh this benefit for sleep.
Recommendation
Avoid cinnamon-raisin bagels close to bedtime; if consumed, choose a smaller portion earlier in the day and pair with protein or healthy fat to blunt blood sugar spikes.
