Fish is healthy because fish is filled with omega-3 fatty acids and vitamins such as D and B2. Hake fish in particular is rich in calcium and phosphorus and a great source of minerals.
Fish – as part of a balanced – can lower blood pressure and help reduce the risk of heart attack or stroke.
Of course, this recipe can be done without the fish and just the gratin and the vegetables would be just as tasty.
The gratin is healthy because it is made from vegetables like celery, leeks, carrots and paprika which are all very good sources of dietary fiber, a type of carbohydrate that helps pass food through your digestive system.
Although it is true that the potatoes are the least healthy ingredient in this recipe, we reduce their starch content in step 2 in order to make them healthier. It is recommended to eat from 2 to 3 cups of vegetables per day to maintain a healthy diet.
