Short Answer: Canned tuna is good for diabetes because it has protein and omega-3s, which can help you control your blood sugar and protect your heart.
Diabetes is a condition that affects your blood sugar levels and how your body uses insulin.
In diabetes, your body either does not produce enough insulin or cannot use it properly.
Insulin is a hormone that helps glucose (sugar) enter your cells to be used for energy.
Without enough insulin, glucose builds up in your blood, causing high blood sugar.
This can lead to various health problems, such as nerve damage, kidney disease, eye problems, heart disease, and stroke.
One of the key factors in managing diabetes is diet.
What you consume can affect your blood sugar levels, which can impact your diabetes symptoms and overall health.
To effectively manage diabetes, you should consume fiber-rich foods like whole grains, fruits, vegetables, and legumes, and avoid refined carbohydrates like white bread, pasta, and sweets.
Fiber helps slow down the digestion and absorption of carbohydrates, which can prevent spikes in blood sugar.
You should also limit saturated fats and trans fats, which can raise your cholesterol and increase your risk of heart disease, and choose healthy fats like olive oil, nuts, seeds, and fatty fish.
Now, canned tuna is a type of fish that is preserved in a can, either in water or oil.
People usually eat canned tuna as a sandwich filling, a salad ingredient, or a snack.
Canned tuna is good for diabetes because it contains protein and omega-3 fatty acids.
Protein can help you feel full and maintain your muscle mass, which can improve your metabolism and blood sugar control.
Omega-3 fatty acids can lower inflammation, improve blood vessel function, and reduce the risk of heart disease, which are common complications of diabetes.
One ounce (28 grams) of canned tuna can give you about 6–8 grams of protein and 25–56 mg of omega-3s, depending on whether it is packed in water or oil.
This is about 12–16% and 2–5% of your daily needs, respectively.
Protein can positively affect diabetes by helping you regulate your appetite and blood sugar levels.
Omega-3s can positively affect diabetes by protecting your cardiovascular health and reducing inflammation.
Furthermore, canned tuna is a low-carbohydrate food and carbohydrates are the main factor that affects blood sugar levels.
Because canned tuna has little or no carbs, it is good for diabetes.
However, you should be careful about what you eat with canned tuna, such as bread, crackers, or mayonnaise, as they can add carbs and calories to your meal.
You can eat up to two servings of canned tuna per week safely.
More than that can cause mercury poisoning, which can damage your nervous system and kidneys.
Mercury is a toxic metal that accumulates in fish, especially large and long-lived ones like tuna.
Also, you shouldn’t eat canned tuna if you have kidney disease, which is a common complication of diabetes, to prevent worsening your condition.
Because canned tuna is high in sodium, which can increase your blood pressure and fluid retention, and phosphorus, which can interfere with your calcium balance and bone health.
You can buy canned tuna in your local market or online.
Always choose canned tuna that is packed in water rather than oil, as it is lower in calories and fat.
Because oil can add unnecessary calories and fat to your diet, which can worsen your blood sugar control and weight management.
You can store canned tuna in a cool and dry place for up to 2–5 years, depending on the brand and expiration date.
