Nutritional Snapshot
Tuna facts
A typical 85gram (3ounce) can of waterpacked albacore tuna provides about 20g of protein, 2g of carbs, and roughly 100mg of sodium. The omega3 fatty acids it contains are a bonus for heart healtha frequent concern for people with diabetes.

| Brand | Calories (per tbsp) | Fat (g) | Sodium (mg) | Notes |
|---|---|---|---|---|
| Classic (regular) | 90 | 10 | 85 | Made with soybean oil |

| Oliveoil mayo | 80 | 9 | 60 | Higherquality fat, lower sodium |
Why Tuna Might Be a Good Choice
Omega3s and heart health
People with diabetes face a higher risk of cardiovascular disease. The omega3s in tuna (EPA and DHA) have been shown to lower triglycerides and support healthy blood vessels. The National Heart, Lung, and Blood Institute notes that two servings of fatty fish per week can be protective.
Protein for satiety
Protein slows gastric emptying, which helps blunt postmeal glucose spikes. One can of tuna can keep you feeling full for hours, making it easier to avoid highcarb snacks later in the day.
Realworld example
Maria, a 58yearold with Type2 diabetes, started adding a simple tunamayo mix to her lunch salad. After two weeks, she noticed her postlunch blood glucose stayed in the 120130mg/dL rangemore stable than the 150160mg/dL spikes shed seen with carbheavy sandwiches.
Potential Risks & Cautions
Calories and weight management
Even though tuna is lowcalorie, mayo can add up quickly. Overeating the combo may contribute to unwanted weight gain, which can worsen insulin resistance.
Sodium load
Canned tuna often contains added salt. Pair that with the sodium in regular mayo, and you could be approaching 300mg of sodium in a single snack. For those monitoring blood pressure, choose lowsodium tuna or rinse it briefly before mixing.
Unhealthy oils
Some cheaper mayo brands use partially hydrogenated oils or excessive soybean oil, which arent ideal for heart health. Look for mayo made with canola, olive, or avocado oil instead.
Expert tip
A registered dietitian recommends keeping mayo to no more than one tablespoon per serving for most diabetics. This keeps the extra fat and calories in check while preserving the creamy taste you love.
Portion Control & Frequency
How much tuna can a diabetic eat?
Most guidelines suggest 150200g of tuna per day (roughly two standard cans). Spread that across meals rather than consuming it all at once.
How many tablespoons of mayo?
One tablespoon (15g) of light or oliveoil mayo is usually enough to coat the tuna without overwhelming it. If youre watching calories, stick with the light version.

- Breakfast: Greek yogurt with berries.
- Midmorning snack: A small apple.
- Lunch: Tunamayo salad over mixed greens, drizzled with lemon juice.
- Afternoon snack: A handful of almonds.
- Dinner: Grilled chicken, roasted veggies, and a small portion of quinoa.
