Frozen food a cool choice for healthy eating

Foodies may scoff and many people presume it's far from nutritious but frozen food is perfect for healthy and tasty meals on a budget, writes Louise Atkinson

AS the cost of food escalates it may seem more difficult to eat healthily, but in the freezer section of the supermarket is a range of staples that can be used to create wholesome, inexpensive meals - as these recipes show.

Frozen food is often considerably cheaper because it has a much longer shelf life, which means supermarkets can bulk buy without fear of unsold food being wasted.

And it can be better for you: "Frozen food can often be more nutritious than 'fresh'," says dietitian Dr Sarah Schenker.

"Most fresh fruit and vegetables are picked before they are ripe, and stored, then treated, so they can ripen during transportation but, as a result, this gives them less time to develop a full range of vitamins, minerals and antioxidants.

"However, fruit and veg that's destined to be frozen is picked at peak ripeness - when it is most nutritious - and immediately frozen, so it retains its nutrients."

Frozen vegetables are blanched (dipped in boiling water) then frozen within hours of being harvested.

"Although the blanching can cause a small loss of water-soluble vitamins such as vitamin C and B, once frozen nutrients are locked in," says Schenker.

"Vitamin C levels in fresh foods can deteriorate over time, so studies have often found similar levels when comparing fresh with frozen."

Frozen vegetables such as broccoli, cauliflower and green beans are often considerably cheaper than fresh.

Dr Schenker recommends looking out for frozen berries ("a great way to add natural sweetness") and stocking up on frozen peas and sweetcorn ("quick and easy extra veg that can be added to an omelette, pasta or rice").

Dr Schenker says the key to creating a balanced, nutritious meal is to include a good source of protein (meat, fish, eggs, pulses), with healthy carboyhdrates (such as brown rice) and lots of vegetables.

TURKEY MINCE

£3.75 per 500g

THIS meat is rich in protein and an excellent source of nutrients including vitamins B3 and B12 (for healthy blood), B6 (for the nervous and immune systems) as well as selenium and zinc.

Selenium is an important nutrient, protecting cells against oxidative stress (damage caused by harmful, free-radical molecules produced as a result of environmental factors including UV rays and pollution). It's also needed for good thyroid health.

But food production methods and modern diets mean we often lack it. Zinc is needed for immunity, blood sugar control and eye, skin and heart health.

Turkey is also a good source of the amino acid tryptophan, which the body uses to make the hormones serotonin and melatonin (for mood, and sleep respectively). Turkey breast mince (at 2 per cent fat) is usually lower in fat than beef mince (which can be labelled as 5, 10 or 20 per cent fat). Turkey leg mince might be five or seven per cent fat.

COOKING TIP: You can substitute plant-based mince such as Quorn mince (£2.95 for 500g) in most mince recipes, and although slightly lower in protein, it has more fibre. Defrost your mince overnight in the fridge, if you prefer, although you can cook it from frozen in some recipes.

CHILLI

Turkey mince makes a lower-fat chilli than beef mince but is just as high in protein. Kidney beans add protein and fibre (one portion provides nearly all of a woman's daily protein - 45g, men need 55g, according to the NHS - and over half your daily fibre needs of 25g) and the hidden vegetables add up to an impressive four of your five-a-day in one portion.

Per portion: 518 calories, 37g protein, 29g fat, 66g carbohydrates, 13g fibre

Cost per person: £1.50

Serves 4

1tbsp oil

1 onion, finely diced

Chilli flakes

1tsp cumin seeds

1tsp cinnamon powder

1 diced red pepper

200g mushrooms, frozen, no need to defrost

400g frozen turkey mince, no need to defrost

1 tin chopped tomatoes

1 tin kidney beans

300g long-grain rice

Fry onion and spices in the oil for five minutes, until softened. Add pepper and mushrooms. Cook for a further five minutes. Add mince and cook until it breaks up, then add tomatoes and kidney beans. Season.

Bring to the boil, then simmer for 30 minutes. Serve with rice, cooked as per packet instructions.

FISH

Around £2.50 for 500g

Any white fish such as bass, hake, cod or haddock is low in fat, calories and extremely high in protein - plus it's an important source of iodine which is needed for thyroid and brain health.

Look for frozen salmon, which may be a little more expensive but adds extra omega-3s, which are good for heart health and have an anti-inflammatory action, which can help ease joint pain (freezing it doesn't affect its omega-3 levels).

Fish also provides minerals such as zinc (for blood health and immunity), and is a good source of vitamin B6, which helps reduce inflammation.

COOKING TIP: Choose plain fish without a breadcrumb coating, which is healthier and can often be cooked from frozen without the need to defrost.

FISH STEW

This is a high-protein, high-fibre dish. The fibre from the butter beans can help reduce cholesterol levels and encourages the growth of healthy gut bacteria that strengthen immunity. One portion of stew also counts as three of your five-a-day.

Per portion: 485 calories, 41g protein, 21g fat, 47g carbohydrates, 10g fibre

Cost per person: £1.39

Serves 4

1tbsp oil

1 onion, finely diced

3 sticks celery, finely chopped

2tsp paprika

1 tin chopped tomatoes

400ml vegetable stock

500g frozen fish, defrosted, skin removed and cut into small pieces.

100g chorizo (available in frozen pieces, no need to defrost)

1 tin butter beans

Handful fresh parsley, finely chopped

1 baguette

Heat the oil and add onion, celery and paprika and cook for five minutes to soften. Add tomatoes and stock, season with salt and pepper and bring to boil. Simmer for 15-20 minutes to thicken sauce. Stir in frozen fish, chopped chorizo and butter beans. Cook for a further 20 minutes. Sprinkle with parsley. Serve with chunks of warm bread.

COCONUT FISH CURRY

Coconut milk is highly nutritious, providing minerals including manganese, copper, iron and selenium. It contains a fat (called medium-chain triglycerides) more likely to be used for energy rather than stored in the body.

Frozen peas boost protein, add vitamin C and provide one of your five-a-day.

Per portion: 619 calories, 31g protein, 14g fat, 83g carbohydrates, 5g fibre

Cost per person: £1.33

Serves 4

1tbsp oil

1 onion, finely chopped

Thumb-sized piece of ginger, peeled and grated

2 cloves of garlic, crushed

Pinch of chilli flakes

1tbsp curry powder

1 tin coconut milk

Juice of 1 lime or 2tbsp lime juice

500g frozen fish, defrosted, skin removed and cut into pieces

200g frozen peas

300g long-grain rice

Heat oil and add onion, ginger, garlic and chilli flakes. Cook for five minutes, or until softened. Add curry powder and cook for a further minute. Pour in coconut milk, lime juice and 2tbsp of water and bring to a simmer.

Add fish and peas and simmer for 20 minutes. Serve with rice (cooked according to packet instructions).

SOYA BEANS

£2.20 for 500g

THESE are one of the few plant sources of high-quality protein. Like meat, soya beans (also called edamame beans) contain all the essential amino acids the body needs for growth and are a good source of vitamins and minerals including iron, magnesium, phosphorus, potassium and copper.

The protein, antioxidants and fibre in soya beans can help lower cholesterol levels. They contain plant compounds (isoflavones) which may ease menopausal symptoms, improve bone health in older women and reduce the risk of hormonal cancers.

COOKING TIP: Swap peas for soya beans in any meal to boost protein and nutritional profile.

SOYA BEAN DIP WITH FLATBREADS

A soya bean dip makes a nutritious alternative to hummus. The addition of artichoke hearts provides vitamin C, folate (vitamin B9), potassium (which helps regulate blood pressure) and luteolin (an antioxidant that can help lower blood cholesterol) and, along with the radishes, contain prebiotic fibre that good gut bacteria feed on.

Serves 4

200g plain flour

2tbsp oil plus extra for cooking

300g frozen soya beans, defrosted

100g tinned artichoke hearts

150g plain yoghurt

1 clove garlic

Juice of 1 lime

Handful of mint leaves

2 carrots, grated

4 radishes, thinly sliced

Sift flour and add half a teaspoon of salt, 1tbsp of oil and 150ml warm water. Mix into a smooth dough. Turn on to a floured surface. Knead for five minutes. Place in an oiled bowl, cover and leave for 30 minutes.

Blitz soya beans, the remaining oil, artichoke hearts, yoghurt, garlic, lime juice and mint leaves in a food processor to a rough paste. When dough is ready, divide into eight equal-sized balls. Use a rolling pin to make thin circles. Brush a pan with a little extra oil and cook one flatbread over high heat for two minutes on each side.

Repeat with the rest of the dough. Divide the dip between each flatbread and spread over evenly. Add grated carrot and radish slices and roll up.

SPINACH

£1.60 for 900g

Spinach is 90 per cent water (so is low in calories) but it's a good source of beta-carotene (converted in the body into vitamins A, C and K which helps blood clot), iron and calcium.

It also contains plant compounds such as lutein, kaempferol, quercetin and zeaxanthin with powerful antioxidant and anti-inflammatory properties.

Research has linked eating spinach to reducing oxidative stress to cells, eye health, lower blood pressure and reducing the risk of cancer.

COOKING TIP: The flavour disappears when you add it to sauces, which means you can add frozen spinach to meals to increase the nutrient content and even fussy eaters shouldn't notice.

SPINACH PANCAKES WITH POACHED EGGS

These delicious savoury pancakes make a well-balanced breakfast or brunch: they're a clever way to incorporate spinach into the diets of picky eaters. Eggs are a good source of protein to keep you feeling full - 5g per egg. One portion will provide a third of woman's daily protein and nutrients for healthy brain cells and brain function.

Per portion: 298 calories, 14g protein, 27g fat, 16g carbohydrates, 2g fibre

Cost per person: 60p

Serves 4

125g self-raising flour

1tsp baking powder

6 eggs

2tbsp butter

100ml milk

100g frozen spinach, defrosted

Serve with sliced fresh tomatoes

Place flour, baking powder, two eggs, 1tbsp of melted butter, milk and spinach in a bowl. Add a pinch of salt and whizz with a stick blender to make a smooth batter. Heat remaining butter in a non-stick frying pan and add small dollops of batter, making two pancakes at a time. Cook for two minutes on each side. Keep the pancakes warm.

Meanwhile, poach remaining eggs. Serve each pancake with an egg on top and a tomato salad on the side.
