We put all the leftovers in the fridge without really giving it a thought. But are all foods safe to eat even after refrigeration? There are certain foods like onions and potatoes that should not be refrigerated according to the European Food Information Council. They explain that there can be health consequences if you refrigerate garlic, onions and potatoes. While most people follow these guidelines, keeping potatoes in the dark and at room temperature. But what about cooked potatoes? They risk the chances of getting spoiled if not refrigerated in time. Not just that, but studies have shown that there are benefits to eating chilled potatoes, so what are we doing wrong? What Do The Studies Say? According to a study published in Nutrients 2019, there's a special kind of starch called 'resistant starch' that's good for your blood sugar and how your body uses insulin. Potatoes have this starch, and how you cook them changes how much of it they are able to retain. This study looked at 30 women who were overweight and had slightly high blood sugar. They ate two different kinds of potatoes on different days, regular boiled potatoes (which have less resistant starch) and baked potatoes that were cooled (which have more). The study found that the women who ate the cooled potatoes had much lower blood sugar and insulin spikes in the first 30 minutes after eating. Their bodies also released less of a certain gut hormone that affects insulin. Even though both types of potatoes had the same overall effect on blood sugar, the cooled potatoes led to lower insulin levels overall. The women also ended up eating a diet with more carbs and less fat in the two days after eating the cooled potatoes. Basically, this means that eating cooled potatoes, which have more resistant starch, can help women with slightly high blood sugar manage their blood sugar and insulin levels better. What Are Some Risks Of Refrigerating Cooked Potatoes? If cooked potatoes are not stored correctly in the fridge, they can get damp. WebMD tells us that the starches in the potatoes can turn into sugars, and this can make them spoil faster. So, if you don't eat them quickly enough, they might make you sick. It is very important to make sure that the containers that potatoes are stored in are airtight, to prevent excess moisture from entering. It is very important to remember that any time cooked food is stored, there is a risk of food borne illness. If cooked potatoes are not cooled to the proper temperature, and then stored at the proper temperature, bacteria can grow. This bacteria can cause people to become very sick. Because of this, it is very important to follow proper food safety procedures when storing any cooked food, and potatoes are no exception. How To Store Cooked Potatoes Properly WebMD explains that if you need to keep cooked potatoes for a long time, freezing them is a good idea. When you freeze them right, they can stay good for up to a year. This means you can cook a big batch of potatoes and have them ready whenever you want. This is a great way to reduce food waste. To freeze cooked potatoes well, let them cool down completely first. Then, put them in a container that seals tightly, or in a plastic bag. Make sure to get as much air out of the bag as possible before you seal it. This will help them stay fresh and tasty. Freezing them in proper portions will also make it easier to use them later.
