Contrary to popular belief, many canned foods are nutritious and can be part of a balanced diet. Scientific studies support their inclusion in monthly shopping, offering nutritional benefits and savings.
Canned Fish: Canned tuna, sardines, and salmon are excellent sources of protein and omega-3 fatty acids. A study published in the Journal of the Academy of Nutrition and Dietetics found that regular consumption of canned fish is associated with a higher intake of essential nutrients.
Legumes: Canned beans, chickpeas, and lentils are rich in fiber and plant-based proteins. According to the American Heart Association, legumes can help reduce cholesterol and the risk of heart disease.
Vegetables: Canned tomatoes contain more bioavailable lycopene than fresh ones, an antioxidant associated with reducing the risk of cancer and heart disease. Other vegetables like corn, peas, and carrots retain much of their nutrients.
Fruits: Canned fruits in their own juice are a good option. A study from Oregon State University showed that canned pears contain four times more antioxidants than fresh ones.
Economic Aspects
Canned foods are often more economical than fresh ones, especially out of season. Additionally, their long shelf life reduces food waste.
Considerations: Opt for low-sodium products without added sugars. Rinsing canned legumes and vegetables can reduce sodium content by up to 40%.
In conclusion, canned foods can be part of a healthy and economical diet when chosen properly. Their convenience, nutritional value, and cost-effectiveness make them a practical option for many consumers.
Details on mentioned scientific studies
The study published in the Journal of the Academy of Nutrition and Dietetics in 2016 analyzed data from over 17,000 U.S. adults. It found that canned fish consumers had significantly higher intakes of protein, vitamin A, vitamin B12, selenium, and omega-3, compared to non-consumers.
The American Heart Association has published multiple studies on legumes. A 2019 meta-analysis in Advances in Nutrition showed that regular legume consumption is associated with a 7% reduction in cardiovascular disease risk.The Oregon State University study on canned pears, published in the Journal of the Science of Food and Agriculture in 2013, used liquid chromatography techniques to measure antioxidant levels.
