  2. *Indicates significant difference (P < 0.05), compared to fasting values
  3. **Indicates significant difference (P < 0.01), compared to fasting values
  4. ***Indicates significant difference (P < 0.001), compared to fasting values
  5. Values are mean ± SD. Last column shows percent change for the different values, fasting versus 30 min after food intake
