One line of reasoning used to argue oats aren't healthy is that eating them can lead to spikes in blood sugar (glucose). This seems to be linked to the rising use of glucose monitors by people who don't have diabetes.
Both Weet-Bix and rolled oats are healthy whole-grain options, but rolled oats are generally considered slightly healthier as they are less processed and naturally lower in sugar and sodium, while Weet-Bix offers added vitamins and iron but has more fortified ingredients.

Pastries, such as croissants, muffins, and donuts, are some of the unhealthiest breakfast choices. They're typically made with refined flour, added sugar, and unhealthy fats, creating a calorie-dense, sweet food with little nutritional value.
Cereals made from ingredients like oatmeal or grain-free alternatives like almond and buckwheat generally have fewer heavy metals than rice-based cereals, making them a healthier choice.
