• As previously stated, young adults tend to have bad dietary habits, fact confirmed by our study.(1)

• Medical students tend to have bad eating and fitness habits (2)

• FFQ are time consuming and subjected to memory biases, but are a good nutritional assessment tool. (3)

• Sweets and fat consumption lead to increased incidence of overweight and obesity.

Discussions

• Medical students tend to consume higher

amounts of all food groups and do not engage

in regular physical activity.

• First year students tend to have better eating

habits.

• Future perspective - A nutritional evaluation at

the start of each school year with individualised

diet recommendations.
