If you've stored your oats in an airtight container in the fridge, they can last for up to 5 days. But, if you've added some fresh fruits or nuts, they might not last as long, because let's face it, fresh ingredients can go bad quickly. It's like leaving a banana on the counter, it's not going to last forever, right?
Another thing to consider is the type of milk you used, because some milks can spoil faster than others. For example, if you used almond milk or soy milk, your oats might last a bit longer than if you used cow's milk. It's like the difference between a durable sneaker and a delicate flower, one can withstand the test of time, while the other needs a little more care.
Now, you might be wondering, what happens if I leave my oats out at room temperature? Well, let's just say it's not a good idea, because bacteria can grow quickly in oatmeal, especially if it's been sitting out for too long. It's like leaving a pet alone for too long, it needs attention and care to stay happy and healthy.
