Are Tinned Vegetables and Frozen Food Really Bad for Health? And which of these two is the right one to consume?

Which is healthier between tinned and frozen vegetables?

As fresh vegetables and fruits are considered the best and healthy. But, as soon as they are plucked from the branch of the tree. By the way, the amount of these nutrients gradually starts decreasing. That is why, if they are cooked after some time after breaking, the nutritional content of them may be slightly reduced.

After being harvested, fruits and vegetables use their nutrients to try to keep their cells alive. However, some nutrients like vitamin C are affected by exposure to air and sunlight. However, when they are kept in the fridge, this process of breakdown of nutrients slows down.

Know what happens in freezing?

In 2007, researcher Davis associated with the University of California, taking into account many studies related to vegetables, fruits and herbs, stated that if vegetables like spinach are kept at room temperature, their vitamin C is completely lost in 7 days.. Whereas, keeping it in the fridge reduces it by 85 percent in 7 days. Whereas, carrots kept at room temperature have only 27% less vitamin C in the same period.

Actually, the process of oxidation stops during freezing. Due to which the color of things kept in the freezer starts changing.

However, in the commercial speed freezing process, it is frozen within a few hours after breaking the vegetables. During this, after cleaning the vegetables, they are dried very quickly at high temperature. In this process additional enzymes are inactivated. Due to which, the color and texture of the vegetables do not change. Nutrient levels are also reduced in this process. But, it cannot be considered much less nutritious than the vegetable that reaches your plate from the farm.

But, the most important thing is to consume fruits and vegetables, which are very important for your health.
