In my years of medical practice, I have found that many patients are convinced of the idea that the fresher the food, the better. However, some things are not so simple. Today, I'd like to share with you a little story I came across at the clinic, as well as some scientific knowledge about food storage.
I remember one time, a young mother came to my clinic with her small child. The child was brought to the doctor with indigestion and diarrhoea. After asking the children about their eating habits in detail, I found out that the problem was on their dining table. The mother pays so much attention to the freshness of the food that she refuses to let her child eat even slightly ripe bananas, believing that it is a sign of "not being fresh". However, the fact that bananas are converted into sugar during the ripening process is not only easier to digest, but also adds a natural sweetness, making them a better choice for small children.

Scientific explanation of the maturation process:
First of all, we need to understand the ripening process of bananas. As bananas ripen and mature, the starch inside them is gradually converted into sugar. This transformation process is actually facilitated by the enzymes produced by the bananas themselves. In other words, as the color of the banana peel turns from green to yellow, and even small black dots begin to appear, its sweetness and aroma increase. That's why some people prefer to eat bananas that have a bit of a dark spot on the surface – because they're sweeter and more fragrant!
Health Benefits:
From a health perspective, ripe bananas are easier to digest than infully ripe bananas. Because by the time bananas are ripe, complex carbohydrates have been broken down into simple sugars that are easier for the body to absorb. In addition, the amount of antioxidants in ripe bananas will also increase. This means that they can help us fight free radicals and protect the body from oxidative stress.
Suitable storage time and judgment method:
An easy way to tell how ripe a banana is to look at its skin color and texture. The more yellow the skin and the more dark spots on it, it usually means that the banana is more ripe. As for storage, bananas should ripen naturally at room temperature, and if you want to slow down the ripening process, you can put them in the fresh bin of the fridge, but remember to only do so when they have reached your preferred ripeness, as low temperatures will stop the ripening process.

Storage changes: the wonderful process of starch sweetening
The rich starch in potatoes is one of its main components. Freshly dug potatoes are high in starch, but if they are stored under the right conditions, these starches are gradually converted into sugars. This transformation not only improves the taste of the potatoes, making them fluffier and sweeter when cooked, but also better develops that lovely golden hue during cooking.
Health Tips: How to Reduce the Health Risks of Potatoes
Although potatoes are a healthy food, improper storage can lead to an increase in solanine, a naturally occurring toxic substance that can increase especially when potatoes sprout or turn green. Fortunately, proper storage can reduce these harmful substances. By keeping potatoes in a cool, dry, and dark environment, the growth of solanine can be effectively controlled, making potatoes safer and tastier.
Ideal Storage Conditions: Best Practices
Ideal storage conditions are essential to maintain the quality of the potatoes. It is best to store potatoes in a well-ventilated place with a temperature of about 4°C to 6°C. Avoid keeping potatoes in the refrigerator, as too low a temperature will speed up the conversion of starch into sugar, affecting taste and health. In addition, making sure that the storage space is dark can prevent the potatoes from sprouting and prolong their useful life.
With these simple storage tips, you'll not only be able to keep your potatoes in the best taste and nutrients, but you'll also be able to enjoy delicious potato treats when you need them. The next time you buy potatoes that aren't so "fresh", maybe that's when they're at their tastiest.
red wine
The art of aging
As a doctor with many years of experience in outpatient clinics, I am not only concerned about human health, but also about foods that can promote health in my daily life, such as red wine. Many people think that the fresher the wine, the better, but red wine is different, its charm lies in the ageing. Aged wines develop more complex, deeper flavours than new wines.
Behind the science
The aging process of red wine is a complex process of chemical change. During storage, tannins, acidity and other natural compounds gradually interact, which not only softens the taste but also increases the diversity of aromas. For example, tannins combine with proteins to give the wine a rounder body and reduce that immediate astringency.
Health & Taste
Regarding health, the antioxidants of aged red wine, especially resveratrol, increase due to chemical reactions over a long period of time. These antioxidants are especially beneficial for heart health and can help reduce the risk of cardiovascular disease. On the palate, the flavors of the red wine become richer and more layered over time, releasing notes of ripe fruit, vanilla and even chocolate, making the tasting a pleasure.
Best time to drink
So, how long should red wine be stored? It depends a lot on the type of wine and the method of production. In general, higher-quality red wines can be aged for more than 5 years, while some special top wines can even be stored for decades. The best flavor of a red wine can be judged by its color and sediment, which usually gradually changes from a bright red to a deep brick red, and an increase in sediment is also an indication that the wine is ripe.
Enjoying a glass of aged wine is one of my favorite ways to relax after a busy medical schedule. It's not just a drink, it's a science, it's an art. Next time you choose a wine, maybe try to spend more time in the cellar and enjoy the unique twist.
