A lot of movement 12 week ultrasound??

Just wondering if it’s normal for the baby at this stage to be so active? I had an ultrasound today and the baby was turning flips and kicking sooo much. I didn’t know if it was a sign I’m not eating good foods? I’ve been craving sweets so I didn’t know if the food I was eating could maybe make the baby move more or if it’s normal for them to be so active at this stage
