Roast potatoes may add to breakouts if you eat it often or in large amounts.
One serving brings a high glycemic load (fast sugar, which raises insulin) and a little saturated fat or omega-6. It also gives omega-3 and polyphenols, which the research links to calmer skin.
Why this score
- Glycemic: 32 g carbs at GI 85 = glycemic load 27.2 (high). Fast sugar raises insulin, and insulin can lift skin oil and clog pores.
- Dairy: none.
- Inflammation: 1.2 g saturated fat and 1.8 g omega-6, a small load.
- Skin Boost: 0.1 g omega-3 and medium polyphenols, which small trials link to fewer inflamed spots (+5.8).

Not medical advice. This score is for roast potatoes on its own. What you eat with it changes the result: protein and fat slow the sugar spike, and breakouts usually show up 3 to 7 days after a meal, which is why SpotBite tracks your meals over time rather than judging one food. Diet is one factor among many (hormones, genetics, skincare, stress, sleep).
