3.4.1. Example 1: Milk Products

The group of dairy consisted of milk, yoghurt, curd cheese, cream, cheese and butter made from cow's milk. Lactose-free products and products made from sheep's or goat's milk were not included.

A total of 68.8% (*n =* 11) of respondents showed a change in ACS after taking dairy products. Among the foods tested, milk products are the ones that most often lead to an increase in ACS levels.

On average, the analysis shows a significant increase in ACS on days dE + 1, dE + 2 and dE + 3 with a sustained effect observed for three days.

Evaluating the milk products, we found two differently reacting groups as shown in Figure 4. Group 1 (*n =* 5) initially responded to the intake of milk products with a decrease in ACS followed by a significant increase in the ACS rating after 1 day. In contrast, group 2 (*n =* 6) showed a significant increase in the ACS rating on the day of consumption of dairy.

**Figure 4.** Individual reactions of participants to dairy products, measured by ACS. Group 1 (participants with a decrease of value in ACS at day of reintroduction) vs. Group 2 (participants with an increase of value in ACS at the day of reintroduction) *p* < 0.05 \*, *p* < 0.01 \*\*, *p* < 0.001 \*\*\* (one sided *t*-test). dE − 1: day before reintroduction, dE: day of reintroduction, dE + 1: day 1 after reintroduction etc.

Figure 4, Tables 3 and 4 show the daily courses of the mean values as well as the standard deviations of all children in the respective groups. In addition, the individual time courses of each child are displayed.

3.4.2. Example 2: Corn

Figure 5, Tables 5 and 6 show the behavioral reactions to corn.

In total, seven children (43.8%) responded to the intake of products containing corn, as shown in Figure 5.

Group 1 shows a decrease in the ACS value on the day of corn introduction, the largest increase (11 points) on day dE + 1 and a value of 0 on day dE + 3.

Group 2 shows an ACS value increase directly on the day the corn is taken. This is significant on day dE + 1 and dE + 2.

**Figure 5.** Individual reactions of participants to corn, measured by ACS. Group 1 (participants with a decrease of value in ACS on the day of reintroduction), vs. Group 2 (participants with an increase of value in ACS at the day of reintroduction) *p* < 0.05 \*, *p* < 0.001 \*\*\* (one-sided *t*-test). dE − 1: day before reintroduction, dE: day of reintroduction, dE + 1: day 1 after reintroduction etc.
