It’s better to consume fresh greens and legumes. Firstly, fresh products are richer in nutrients. Moreover, canned foods maybe contain dangerous toxic chemicals and high amounts of salt.
Are canned products dangerous?
According to a report by the Center for Environmental Health, there are canned foods that still contain dangerous toxic chemicals. According to the report, about 40% of the tested canned foods contain a dangerous chemical, called BPA.
Exposure to the BPA has linked to many types of cancer, diabetes, obesity and heart disease!
Additionally, according to another study, canned foods may contain carcinogens. They seem to be developed during the processing method.
Is the extra salt in canned products bad for you?
Most canned foods are packed with salt. Salt is the cheapest way to preserve the food. Also, it’s used as a cheap seasoning. But, excessive salt intake has linked to many diseases, such as cardiovascular disease, obesity and high blood pressure!
According to the American Heart Association, we shouldn’t consume more than 2,300 mg of sodium a day. Furthermore, consuming only 1,500 mg of sodium a day is even better!
But, canned foods are pretty high in salt. Canned foods and highly processed products are the main reasons of the extreme sodium intake of the standard Western Diet. Just a teaspoon of salt contains 2,300 mg of sodium! Much more than you need.
Canned foods may contain about 300-600 mg of sodium per serving. You should avoid consuming extra salt. It’s better to prefer fresh foods to protect your heart and good health!
