What are the effects of having a poor diet in my school years (Details inside)?

For instance… I would have frosted flakes or honeycombs sugar serial, pop tarts or instant oatmeal for breakfast with little water, but lots of milk and pop, ( 1 can of cola for breakfast).

School lunch : Thrown in garbage and I buy a one liter container of milk and a hoagie or video games if I felt like going to class.

Supper my dad and I would go to a buffet or order pizza…

Thursdays Sports bar chicken wings 100 per person and a pitcher of cola each.

Summers when living with my grandfather we ate healthy, home made stew, cantaloupe and grapefruit, .. no pop, take out. One dinner at a buffet house for my birthday. One glass of milk a day.

Nighttime snack can of oysters or sardines in soya oil with bread.
