Are Canned Foods Nutritious for My Family

 

Canned foods can play an important role in an overall healthy diet. People who consume more canned foods tend to have a higher intake of fruits and vegetables and a higher intake of nutrients compared to people who consume fewer canned fruits and vegetables.

How Canned Foods are Made

Canned fruits and vegetables usually are canned within hours after picking. Some procedures may vary depending on the food item, but once the fruit or vegetable has been picked and transported to the canning facility, it goes through three major steps.

Processing: Fruits and vegetables are washed and often peeled, cut, chopped or pitted before canning. Certain varieties of fruits and vegetables may be blanched beforehand. Dried beans are hydrated and blanched. Once the food is prepared, the cans are filled with either water or juice and seasoned accordingly.
Sealing: After processing, the food is put into cans and the lid is sealed.
Heating: Once the can is sealed, it is quickly heated to a precise temperature for a specified amount of time to kill harmful bacteria and prevent spoilage. After it is heated, it is quickly cooled.

Benefits of Canned

Fruits and vegetables used for canning are picked at peak freshness, ensuring the best flavor and nutrient quality. Canned foods can be just as nutritious as fresh and frozen foods because canning preserves many nutrients. The amount of minerals, fat-soluble vitamins, protein, fat and carbohydrate remain relatively unchanged by the process of canning. But, because the canning process requires high heat, canned goods may have less water-soluble vitamins such as vitamin C and B vitamins. However, the heating process that may harm some vitamins can actually increase the antioxidant content. For instance, canning increases the amount of lycopene in tomatoes.

Canned foods are a convenient and affordable way to incorporate more fruits and vegetables into your diet. The process of canning ensures a long shelf life of at least one to five years. This may be beneficial for individuals who often throw away fresh produce due to spoilage.

Making Wise Choices

While canned foods can be easy and convenient, there are factors to consider when choosing nutritious options. When purchasing canned fruit, pick varieties that are canned in water, 100 percent juice or in its own juices. Many varieties of fruit come packed in light or heavy syrup, which equates to added sugars. Choose canned vegetables without added salts, labeled “no salt added” or “low sodium.” Be mindful that cans marked “reduced sodium” are not necessarily sodium-free. Draining and rinsing canned beans and vegetables can reduce the sodium content as well.

Avoid cans with dents, bulges, cracks or leaks. This may be a sign of the bacteria that causes botulism. Damage to the can may allow air to enter, creating the ideal environment for Clostridium botulinum to grow. Botulism is more common in home-made canned goods that are improperly handled and is extremely rare in commercially packaged canned goods.

How Vitamin C Supports a Healthy Immune System
 

Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Because your body cannot make vitamin C, it must come from the foods you eat every day. 

Research shows vitamin C is essential for the growth and repair of tissue all over the body. Vitamin C helps heal wounds and repair and maintain healthy bones, teeth, skin and cartilage — a type of firm tissue that covers the bones. As an antioxidant, vitamin C fights free radicals in the body which may help prevent or delay certain cancers and heart disease, and promote healthy aging. Vitamin C from foods also seems to reduce the risk of cartilage loss in those with osteoarthritis. Though it may not keep you from catching a cold, there is some evidence that high doses of vitamin C may decrease the length of cold symptoms by as much as one to one-and-a-half days for some people. However, other studies did not result in the same findings, and the risk of side effects is greater with high doses of vitamin C supplements, so check with your doctor or dietitian before taking.

Sources of vitamin C are abundant and extend well beyond the ever-popular orange or orange juice. Many fruits and vegetables supply this vital vitamin. Sources of vitamin C include citrus fruits, tomatoes, potatoes, strawberries, green and red bell peppers, broccoli, Brussels sprouts and kiwifruit, among others. You can enjoy these foods raw or cooked, but it's important to note that fruits and vegetables lose vitamin C when heated or stored for long periods of time. To get the most nutrients, eat them as soon as possible after shopping and consider steaming or microwaving vegetables for short periods of time to limit nutrient loss.

Vegetarians may be especially interested to know that vitamin C helps the body to better absorb non-heme iron — the kind from plant foods such as beans, spinach and quinoa. To get this benefit, combine vitamin C-rich foods with iron-rich plant foods in the same meal. For example, combine black beans and salsa or create a flavorful spinach salad with strawberries and mandarin oranges.
