As thousands of children revise for exams experts have said poor food choices could have a negative impact on brain functions.
Nutritionist Diana Wright told Premier about why giving sweet snacks all the time to children is a bad idea.
"We do use up a lot of glucose to be thinking but actually we also need protein and protein stops the lows that come with the highs," she explained.
A new poll found one in four parents admits to feeding their kids things like ice cream to help reduce their stress - 24 per cent said they gave chocolate and 15 per cent said they offered fizzy drinks.
The poll commissioned by online ethical grocer, Farmdrop of 1,500 British adults and 500 students also found 11 per cent give their children a take-away at least once a week during exam season, while just 3 per cent offer healthy fruit and vegetables as a revision session snack.
Wright told Premier healthier snacks and trusting God can make all the difference.
"Knowing he's there right beside you and helping you along the way," she said.
"Just rest in his presence, rest in prayer and peace as well as good protein and slow-release carbohydrates throughout the day."
