Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Sardines are often recommended for supporting dental and bone health due to their rich nutritional profile. Scientifically, sardines are an excellent source of calcium, particularly when the edible bones are consumed, as well as vitamin D and phosphorus. Calcium is a primary mineral in the formation and maintenance of strong teeth, and vitamin D enhances calcium absorption and utilization, which is critical for tooth mineralization and integrity. Phosphorus also plays a vital role in the structure of teeth and bones. Multiple studies have shown that adequate intake of these nutrients is associated with improved dental health and reduced risk of tooth loss, especially in older adults. A 2016 review in the journal Calcium and Bone Metabolism emphasized the importance of dietary sources of both calcium and vitamin D for dental and bone health. Furthermore, sardines are a source of omega-3 fatty acids, which may reduce gum inflammation and support periodontal health, though more direct research is needed in this specific area. In summary, the use of sardines for supporting the teeth is well-supported by their nutrient content and scientific understanding of dental nutrition, making them a scientifically validated food for this body system.
