Sardines: A Nutritional Powerhouse
Sardines are a small, oily fish, but they pack a significant nutritional punch. They are rich in omega-3 fatty acids, high-quality protein, and essential vitamins and minerals like Vitamin B12, Vitamin D, calcium, and selenium. Their low position on the food chain means they also have lower mercury levels than larger fish like tuna. But the way they are canned—in water or olive oil—alters their final nutritional profile.
The Breakdown: Sardines in Water
Sardines packed in water are the leanest option. Since water contains no fat or calories, it doesn't add to the nutritional value of the fish itself. For a 3.75-ounce can (around 106 grams) of sardines in water, you can expect approximately 120 calories and 8 grams of total fat.
Benefits of Water-Packed Sardines
- Lower Calorie Count: For individuals watching their caloric intake for weight loss or maintenance, water-packed sardines are the clear winner.
- Original Flavor: Preserving sardines in water allows their natural, distinct fish flavor to shine through, without any influence from added oils.
- Dietary Versatility: A neutral base makes them highly versatile for recipes, allowing you to control added fats and flavors. They are great for salads or mixing into spreads.
- Pure Omega-3s: Since the liquid is often drained before consumption, water-packed sardines ensure you get the fish's omega-3s without extra fat from the oil.
The Breakdown: Sardines in Olive Oil
Sardines packed in olive oil, particularly extra virgin olive oil (EVOO), have a higher fat and calorie content. The oil itself adds a significant number of calories, but it's important to distinguish between different types of oil. A can of sardines in oil has about 191 calories and 10.5 grams of total fat.
Benefits of Olive Oil-Packed Sardines
- Healthy Fats and Antioxidants: Extra virgin olive oil is high in monounsaturated fats and antioxidants, which have heart-healthy benefits of their own. When you eat the oil, you get these additional nutrients.
- Improved Flavor and Texture: The olive oil infuses the fish, resulting in a moister texture and a richer, more complex flavor profile that many find more appealing.
- Potential for Increased Vitamin D: While some of the fish's fat-soluble Vitamin D leaches into the oil, studies suggest that some olive oil-packed versions may retain more vitamin D in the flesh compared to water-packed ones, though results vary.
- Enhanced Omega-3 Absorption: The fat from the olive oil can aid in the absorption of the fat-soluble vitamins and omega-3s from the fish.

Making the Best Choice for Your Diet
Your health goals are the main factor in deciding between sardines in olive oil and water. For someone aiming to reduce their overall calorie and fat intake, the water-packed option is the most straightforward choice. If you're looking for a richer flavor and don't mind the extra healthy fats, sardines in extra virgin olive oil offer a delicious and nutritious alternative. A key factor is what you do with the liquid; draining the oil removes most of the added calories.
The Verdict: Which is Healthier?
Both versions are excellent sources of essential nutrients. No single option is universally 'healthier' for every person. The best choice is the one that aligns with your individual dietary needs and taste preferences. Water-packed sardines provide a lower-calorie, leaner profile, while high-quality olive oil-packed sardines offer a more decadent flavor and additional healthy monounsaturated fats. Ultimately, incorporating sardines into your diet in any form is a positive step for your health.
Conclusion: Personal Preference Prevails
Ultimately, the choice comes down to your personal health and flavor preferences. If you are focused on weight management or controlling caloric intake, water-packed sardines are the ideal option, especially if the liquid is drained. If you want a more flavorful and richer profile with the added benefits of quality olive oil and don't mind the extra calories, the oil-packed variety is a fantastic choice. The most important takeaway is that both are far superior to highly processed protein sources, so including either version of this small but mighty fish in your regular diet is a win for your health.
