I have just completed the Omega-3 Centre’s quiz to check my omega-3 intake. In the past week I’ve had poached eggs with salmon (brunch with friends), grilled barramundi (birthday lunch) and prawns (see the picture above) so I passed with flying colours. But what if you don’t like fish? It can be pretty hard to eat enough omega-3 fats from non-fish foods alone. That’s because alpha-linolenic acid – the short chain plant form of omega-3 – does not convert very well to the effective long chain form of omega-3 – EPA and DHA.

A recent study published in the journal Lipids found that when mice were fed bifidus bacteria, which is added to some brands of yoghurt, along with alpha-linolenic acid, the levels of EPA were higher than if they ate the ALA alone. Because it’s an animal study we can’t assume that the same applies to humans. However it’s a distinct possibility.

There’s no denying that eating fish is good for you. One of the key reasons is that it’s a great source of polyunsaturated fat – in particular the omega-3 fats called EPA and DHA. These fats are help reduce inflammation, clotting, high triglycerides (a type of fat in the blood) and help keep the blood vessels flexible. They are a critical part of brain growth and visual and nervous system development. Some parents and teachers swear by fish oil as a solution to lack of concentration and unruly behaviour in kids although the scientific evidence is not so certain about this.

The Nutrient Reference Values for Australia and New Zealand have a ‘suggested dietary target’ of 610mg per day for men and 430mg per day for women of long-chain omega-3’s.

The short answer is yes – you can eat mussels if you have high cholesterol. Mussels are low in kilojoules, cholesterol and fat. The little fat they do have is mostly healthy unsaturated fat with plenty of omega-3’s to help stabilise the heart muscle, reduce triglycerides (a type of fat in the blood), make arteries more elastic (which helps reduce blood pressure) and reduce blood clotting and inflammation.

Douse your mussels with butter, cream or other saturated fat and they will be more of a heart hazard than anything else. But if you eat them as we did at the Boat Shed Cafe in Nelson (northern tip of New Zealand’s South Island) – steamed with garlic, wine and parsley and served with a local pinot gris – your heart and your taste-buds will be very happy.

Eighty percent of our adult brain is formed by the age of three. So just at the time when our toddlers have learnt that saying “NO” causes the big people around them to act in all sorts of funny ways, we need to make sure they somehow get enough brain nutrients into them, particularly iron, zinc and omega-3 fats.

Iron carries oxygen around the body. If a muscle is deprived of oxygen, it dies. If a toddler doesn’t get enough iron the brain doesn’t get enough oxygen. It can’t develop so well – and the damage is irreversible.
