A 49p snack packs more calcium than milk and offers benefits for the heart, brain, and bones. While milk is a well-known source of calcium, sardines—available in tins for as little as 49p—provide a surprisingly nutrient-rich alternative.
Calcium Content in Sardines
A cup of milk contains about 300mg of calcium, but a 100g tin of drained sardines with bones provides nearly 400mg. This amount covers roughly half of the daily calcium requirement for most adults, which is 700mg according to the NHS. However, consuming more than 1,500mg of calcium daily may lead to stomach pain and diarrhoea.
For those who are lactose intolerant, sardines offer an excellent dairy-free calcium source. Aldi currently stocks a pack for just 49p. A 60g serving of canned sardines in oil provides 240mg of calcium, while a 50g serving in brine contains 340mg.
Why Calcium is Essential
Calcium is vital for building and maintaining strong bones and teeth. It also supports heart function, blood pressure regulation, and blood clotting. Adequate calcium intake helps prevent osteoporosis, a condition that weakens bones and increases fracture risk. Additionally, calcium supports brain health by regulating neurotransmitters and aiding memory formation. Low calcium levels may contribute to neurological issues such as confusion, memory loss, and depression, and have been linked to disorders like Alzheimer's, Parkinson's, and Huntington's disease.
Vitamin D and Omega-3s in Sardines
Vitamin D is essential for calcium absorption, and sardines are rich in this nutrient, making them a valuable food during winter. Sardines also provide omega-3 fatty acids, which reduce the risk of heart disease by lowering triglycerides, blood pressure, and blood clot formation. Some studies suggest omega-3s may help reduce the risk of dementia and Alzheimer's disease.
Delicious Ways to Eat Sardines
- Eat them straight from the tin.
- Add to pasta dishes, tacos, or sushi.
- Mash with lemon juice and black pepper, then spread on wholegrain toast.
- Toss into a fresh green salad for a wholesome lunch.
- For a Mediterranean twist, stir into pasta sauce.
- Blend with cream cheese, garlic, and herbs for a rich spread.
Sardines are a nutritious and budget-friendly fish that can be enjoyed in many ways, making them an excellent addition to a healthy diet.
