- Canned tuna fish has also been linked to alleviating symptoms of arthritis. A study published in the journal Arthritis Research & Therapy found that consuming omega-3 fatty acids, such as those found in canned tuna fish, reduced joint pain and inflammation in individuals with rheumatoid arthritis.
- Additionally, canned tuna fish has been shown to alleviate symptoms of depression. A study published in the Journal of Clinical Psychopharmacology found that consuming 100 grams of tuna fish three times a day for three weeks reduced depressive symptoms in individuals with major depressive disorder.
Comparison of Omega-3 Fatty Acid Content of Canned Tuna Fish with Other Food Sources
Understanding the omega-3 fatty acid content of canned tuna fish and other food sources can help you make informed dietary choices to reap its potential health benefits.
| Foood Source | EPA (g/100g) | DHA (g/100g) |
|---|---|---|
| Canned Tuna Fish (Light) | 0.7 | 1.2 |
| Canned Salmon | 1.1 | 2.1 |
| Chia Seeds | 0.2 | 0.3 |
| Walnuts | 0.5 | 0.5 |
The Omega-3 Index is a measure of the combined levels of EPA and DHA in the blood, which has been linked to cardiovascular health. Consuming 100 grams of tuna fish three times a day for three weeks increased the omega-3 index by 20% in a study published in the Journal of Nutrition.
Role of Vitamin D in Maintaining Strong Bones and Immune Systems
