Grape Nuts are actually pretty low on the nutrition scale (don't read the ingredients/nutrition box if you don't want to be depressed). Upgrade to Ezekiel 4:9 which is similar in concept but 100x more healthful.
The banana is adding so much sugar that isn’t really that healthy. Fruit on cereal is sorta like loading up a salad with dressing, croutons and bacon bits.
Bananas in particular are pretty high in sugar, and other than potassium their nutrient density is nothing special.
Jesus, please stop spreading this kind of nonsense. It’s totally fine for people to eat a banana 7 days a week, 365 days a year as part of their breakfast.
Also, their nutrient density is perfectly fine. It’s high in fiber, potassium, vitamin C, and vitamin B6.
that sugar comes with fiber though so it's okay. the problem is the sheer amount of just sugar, which eg frosted flakes has an overabundance of. A banana is fine.
