This Is What Happens to Your Body If You Eat Canned Tuna Every Day
Canned tuna is a popular food due to its convenience and nutritional profile, but consuming it daily can have several effects on your body, both positive and negative. It’s important to consider not only the benefits but also the potential health problems associated with eating canned foods.
Below, we discuss the changes you may experience by incorporating canned tuna into your daily diet.
High-Quality Protein Supply
Canned tuna is an excellent source of high-quality protein, essential for repairing and building tissues, including muscles and organs.
A 100-gram serving of canned tuna provides approximately 25 grams of protein, which contributes significantly to your daily needs. Consuming enough protein is crucial for maintaining muscle mass, especially if you lead an active lifestyle.
Benefits of Omega-3 Fatty Acids
Tuna is rich in omega-3 fatty acids, known for their benefits for heart and brain health. Omega-3s help reduce inflammation, lower triglyceride levels, and improve brain function.
Including canned tuna in your daily diet can help maintain a healthy heart and support cognitive well-being.
Vitamin and Mineral Supply
Canned tuna is a good source of several essential vitamins and minerals, including vitamin D, vitamin B12, and selenium. Vitamin D is important for bone health and the immune system, while vitamin B12 is essential for red blood cell production and nerve function. Selenium acts as an antioxidant, protecting cells from oxidative damage.
Mercury Concerns
The Food and Drug Administration (FDA) recommends limiting tuna consumption to no more than 2-3 servings per week to minimize the risk of mercury toxicity.
Risk of Excessive Sodium Consumption
Canned tuna may contain high levels of sodium, especially varieties in brine or with additives. Excessive sodium consumption can contribute to high blood pressure and increase the risk of cardiovascular disease. To reduce your sodium intake, choose tuna canned in water and look for low-sodium options.
Considerations Regarding Bisphenol A (BPA)
Some tuna cans may be coated with bisphenol A (BPA), a chemical that has been linked to health problems, including hormonal disruption and an increased risk of certain cancers. Choose brands that clearly state their cans are BPA-free to minimize this risk.
Health Problems Related to Canned Foods
Presence of Preservatives and Additives: Canned tuna may contain preservatives and additives to extend its shelf life. Some of these additives can have negative health effects if consumed in excess. Read labels and choose products that contain as few additives as possible.
Fish Quality: The canning process can affect the quality of the fish. In some cases, the tuna used in cans may not be as fresh as fresh fish available in the market. This can impact the nutritional content and safety of the product.
Nutrient Loss: Although canned tuna is nutritious, the canning process can cause the loss of some heat-sensitive nutrients, such as certain B vitamins. Be sure to supplement your diet with other sources of essential nutrients.
Recommendations for Healthy Consumption
To enjoy the benefits of canned tuna without incurring the associated risks, follow these recommendations:
Vary your protein source: Alternate tuna with other protein sources such as chicken, eggs, legumes, and tofu to reduce mercury exposure.
Choose tuna in water and low in sodium: Opt for versions canned in water and check labels to select products with low sodium content.
Consume in moderation: Limit consumption of canned tuna to 2-3 times per week to minimize exposure to mercury and other potential contaminants.
Look for packaging alternatives: Choose canned products in BPA-free containers to reduce exposure to this chemical.
