Nutritionist: Eating Healthy from Convenience Stores is Simple

Busy lifestyles often lead people to rely on convenience store meals, but concerns about nutrition and health risks associated with microwaved food are common. Nutritionist Yang Ssu-han clarifies that the heating method is less important than the food's content. Microwaving uses microwave energy to vibrate water molecules, generating heat. When used normally, it does not make food radioactive or carcinogenic. In fact, it can preserve certain nutrients better than prolonged cooking methods.

What needs attention is not the 'microwave' heating method, but what kind of food we have been choosing long-term.

The real health concerns arise from the food choices themselves. Consistently eating single microwave main dishes without pairing them with other foods can lead to issues like excessive sodium, often found in sauces and flavorings of dishes like curries, pasta, and soups. Combining these with other high-sodium items like oden or instant noodles can easily exceed daily intake limits, straining the cardiovascular system and kidneys.

Microwave heating time is usually shorter, and the amount of water used is less, so some nutrients that are easily affected by high temperature and water, such as vitamin C and some B vitamins, may not be lost more.

Furthermore, many convenience store meals lack sufficient vegetables and dietary fiber. While some may appear to have greens, the quantity is often minimal. This deficiency can cause digestive issues and affect blood sugar control, especially when paired with high-refined carbohydrate meals like fried rice or white bread options. These meals also tend to be high in fats, saturated fats, and calories due to ingredients like fried meats, sausages, and creamy sauces, increasing risks of weight gain and related health problems.

If one meal has already eaten a high-sodium bento, and is paired with oden soup, tea eggs, instant noodles, processed meat, or heavy-flavored snacks, the daily sodium intake can easily exceed the standard.

Processed meats like ham, bacon, and sausages are also frequently consumed, contributing to high sodium and fat intake while displacing healthier protein sources like chicken, fish, eggs, and tofu. Over time, a diet dominated by similar convenience meals can lack diversity, missing out on essential vitamins, minerals, and phytonutrients found in a variety of fruits, vegetables, whole grains, and nuts. Yang emphasizes that convenience store meals are not inherently bad; their advantage lies in fixed portions and readily available nutrition labels, which can be useful for weight or blood sugar management. The key is to read labels, prioritize protein and vegetables, and supplement with other food groups to ensure a balanced diet.

When buying a bento, you can also pair it with a box of salad, boiled vegetables, or vegetable soup, but the salad dressing and soup still need to pay attention to sodium content.
