Fish in Your Diet: Recommended Frequency and Its Benefits

Regularly including fish in your diet is an important component of healthy eating. Rich in omega-3 fatty acids, vitamins, and minerals, this food can support overall health. However, it’s essential to consider the optimal frequency of fish consumption to balance the benefits and potential risks associated with excessive intake of certain substances that can accumulate in fish.

What the Evidence Says

According to UK guidelines, adults are recommended to consume at least two portions of fish per week, with at least one portion being fatty fish, such as salmon or sardines. This fish consumption supports cardiovascular health due to its high omega-3 fatty acid content.

The WHO emphasizes the importance of limiting saturated fatty acids in the diet to 10% of total energy intake, making fish a better option compared to some other sources of animal proteins that may contain higher saturated fats. Additionally, the WHO recommends reducing trans fats to 1% of daily energy intake.

US guidelines also emphasize that total fat intake should account for 20–35% of daily energy. Fish, rich in beneficial fats, fits well within these guidelines when adhering to the recommended limits for saturated and trans fatty acids.

How This Looks in Practice

Incorporating fish into your diet can be simple. It can be added to salads, grilled or baked, or even used in soups and stews. Here are a few examples:

• Eat fish at least twice a week
• Include fatty fish at least once a week for optimal benefits
• Choose fresh or frozen fish over canned varieties to avoid excess salt
• Use low-fat cooking methods, such as baking or grilling
