Late-Night Snacks Undermine Sleep Quality

Health experts warn that eating certain foods close to bedtime can disrupt sleep. Acidic foods such as tomato‑based pizza sauce may trigger indigestion and acid reflux, while salty snacks like crisps and salted nuts can dehydrate the body and disturb rest. Ultra‑processed convenience foods, exemplified by instant noodles, are linked to poorer sleep quality and longer time to fall asleep. High‑protein items such as chicken and salami may also delay sleep because the body requires more energy to digest them.

Conversely, low‑calorie options that provide magnesium, potassium, or melatonin can support better sleep. Suggested snacks include a banana with almond butter, protein smoothies (whey, casein, or vegan alternatives), oatmeal (especially overnight oats with dried fruit and seeds), and citrus fruits. These foods help maintain metabolism, promote muscle synthesis, and encourage the production of sleep‑related hormones.
