Understanding the WW Points System
To understand why some tuna varieties are ZeroPoint foods while others are not, it's essential to know how the WW Points system works. The system assigns a value to foods based on their nutritional quality, taking into account calories, protein, saturated fat, and sugar. Foods higher in protein and fiber receive lower point values, while those with more saturated fat and added sugar are assigned higher values. ZeroPoint foods are nutrient-dense items that members are encouraged to eat without tracking, serving as a flexible foundation for meals.
The Verdict: When Tuna is a ZeroPoint Food
The primary factor determining if your tuna is a ZeroPoint food is what it's packed in. Plain tuna packed in water or brine is typically a ZeroPoint food for members whose personalized plan includes fish and shellfish. This is because it is a lean, protein-rich source with minimal fat and no added sugar. However, this zero-point status changes when other ingredients are added.
The Customization of PersonalPoints
With the WW PersonalPoints program, the ZeroPoint foods list is uniquely tailored to each individual based on a personal assessment. This means one member's list may include certain foods that another member's does not, though lean proteins like tuna often feature heavily. For this reason, it's always best for members to consult their WW app to confirm their personalized ZeroPoint food list. It’s also worth noting that the zero-point rule usually applies to the tuna itself, not necessarily the portion size. While you don’t have to track it, WW still encourages mindful eating even with zero-point items.
Water-Packed vs. Oil-Packed Tuna
The most significant difference in point values for canned tuna comes from the liquid it's packed in. The table below highlights the key differences.
| Feature | Water-Packed Tuna | Oil-Packed Tuna |
|---|---|---|
| Points Value | Typically 0 Points (for tuna only) | Points added due to the oil |
| Calories | Lower | Significantly higher |
| Fat Content | Very low | Higher, includes healthy omega-3s |
| Flavor | Mild, less 'fishy' | Richer, more intense flavor |
| Best For | Salads, light lunches, weight management | Meals where fat and flavor are desired |
Navigating Mercury Concerns
Tuna is a healthy, protein-packed choice, but larger species can contain higher levels of mercury. The FDA and EPA offer guidelines for consumption, especially for sensitive groups like pregnant women. When choosing canned tuna, it's helpful to know the different species:
- Light Tuna: Often skipjack, this is a smaller tuna species with lower mercury levels, making it the "best choice" for frequent consumption. It has a softer texture and richer flavor.
- White Tuna: This is albacore tuna, a larger species with a higher mercury content. It has a firmer texture and milder flavor. It's recommended to limit consumption of albacore tuna to one serving per week.
For those looking for the safest and most sustainable choice, pole-and-line caught light skipjack tuna is often recommended.
Creative Ways to Enjoy ZeroPoint Tuna
With tuna as a ZeroPoint foundation, you can build a wide variety of delicious, diet-friendly meals by adding other ZeroPoint vegetables, eggs, or non-fat dairy products.

Conclusion
So, is tuna zero points on Weight Watchers? The answer is that plain, water-packed tuna is often a ZeroPoint food for members on WW programs that include fish and shellfish in their ZeroPoint list, especially under the personalized PersonalPoints plan. However, the point value can increase with portion size or with added ingredients like oil or mayonnaise. To make the most of this versatile, high-protein food, always prioritize water-packed over oil-packed options, and use other ZeroPoint foods like non-fat yogurt and fresh vegetables to build satisfying, low-point meals. Checking your personal WW app is the most reliable way to confirm the points for specific brands and preparations.
