Convenient but selective source of nutrition
Canned food has long been labeled "bad for health", but in reality it is not entirely so. According to Julie Marks' article, these products can still provide many essential nutrients if chosen correctly.
Nutrition expert Suzanne Fisher - Cooper Clinic Medical Nutrition Center (Dallas, USA) - said: "Canned food still retains most of the vitamins, minerals, protein and fiber, contributing to a balanced diet.
Canned fish such as tuna, salmon or sardines are good sources of omega-3 fatty acids for the heart. Vegetables and fruits are often harvested when cooked and quickly canned, helping to preserve nutritional quality. Even the heating process increases the absorption of some antioxidants such as lycopene in tomatoes.
However, some heat-sensitive vitamins such as vitamin C or vitamin B can be lost during processing. However, canned food overall is still a suitable choice in many cases, especially when convenience is needed.
Potential risks when consuming too much
Besides the benefits, the frequent use of canned food can lead to some health risks if not well controlled.
One of the biggest problems is the high sodium content. Many products are added with salt to enhance flavor and extend storage time. Consuming too much sodium can increase blood pressure, thereby increasing the risk of cardiovascular disease.
In addition, some canned fruits contain a lot of added sugars in the form of syrup, easily leading to excess calories and weight gain. Similarly, cream soups or canned stews may contain a lot of saturated fat, increasing bad cholesterol and the risk of stroke.
In addition, some products may contain additives or preservatives, and their long-term effects are still not fully understood. Some metal cans are also at risk of containing BPA compounds - substances that can affect hormones if accumulated for a long time.
Despite the limitations, canned food still brings many benefits such as long shelf life, ease of use and cost savings. It is important that consumers make smart choices, prioritizing products with simple and balanced ingredients in their daily diet.
A healthy diet does not depend on whether you use canned food or not, but on how you use them.
