1. Olive or avocado oil for roasties

Roast potatoes are the stars of Christmas dinner for many people. Without sacrificing their crispy exterior, you can make your spuds healthier by roasting them in olive oil or avocado oil instead of unhealthy saturated fats like butter, goose fat or lard.

Dr Kevin Huffman, bariatric physician and CEO of Ambari Nutrition, says: "These oils are monounsaturated fats, which means they contain far more nutrients, and can improve your cholesterol levels."

As for taste, avocado and extra virgin olive oil both have high smoke points which make them perfect for roasting to get a crispy finish. Avocado oil has a neutral flavour, while olive oil from different areas has different aromas. From France it's buttery and nutty, from Italy it's herbal and peppery, and from Greece it's fruity and fragrant.

If you love traditional turkey for your protein, no swaps here are necessary.

According to Keri Glassman, dietitian and founder of Nutritious Life, loading up your plate with turkey - instead of fattier meats like ham and beef - is actually one of the best things you can do.

She says: "Turkey is a lean quality protein and is very satisfying. Don't be afraid of the dark meat. Yes, it is higher in fat and calories, but it will also be more filling - and could help you eat less sweets. What you should skimp on is the skin."

Dr Menka Gupta, Nutra Nourish, also recommends salmon.

"Fatty fish is another lean protein source that also provides essential amino acids and omega-3 fatty acids," she explains. "These compounds support muscle health and reduce inflammation - which increases cell damage and likelihood of disease."

Stuffing is another festive treat that need not be bad for you. In fact, according to Gupta, you can pack in the nutrients while adding more flavour.

She says: “Swap white bread-based stuffing with sausage for whole grain or multigrain bread stuffing, with a mix of colourful vegetables, nuts, and dried fruits. Whole grains provide fibre which supports your gut health, and the variety of vegetables offers a range of phytonutrients, which promote a healthy balance of gut bacteria."

This has long-term benefits, as well as helping healthy digestion - something that most of us need after the over-indulgence of Christmas day.

"If you wish to add animal protein, consider using lean turkey or chicken sausage instead of pork," Gupta adds.

Gravy is essentially flour, fat and spices. You can make it healthier by choosing healthier flour, a broth base, and by limiting or swapping salt for mouth-wateringly aromatic herbs, such as rosemary, thyme or sage.

Glassman advises: "Use a heart-healthy flour instead of white flour, such as whole wheat flour. If you're not in control of your gravy, stick with portion control of whatever your host is serving. Use 1-2 tablespoons and call it a day."

Gupta adds that a lower intake of salt can lead to lower blood pressure regulation.

Not everyone agrees that mashed potato belongs on your Christmas plate. But for those who love it, Huffman suggests swapping potatoes for cauliflower.

"Transforming mashed potatoes into cauliflower mash offers a creative, nutritious swap for side dishes," he says. "Cauliflower mash is lower in calories and higher in fibre, providing all the taste, with just a fraction of the traditional potatoes calorie and carbohydrate content."

If you can't say no to mashed potato on Christmas day, simply swap poor quality butter and cream for a moderate amount of high-quality grass-fed butter and a splash of skimmed or semi-skimmed milk.

How you treat your veggies can make all the difference. Instead of frying them in lots of butter or oil, steam them or roast them with a little avocado or olive oil to help reduce unnecessary fat.

Roasting also tends to bring out the sweetness in carrots and parsnips. These two festive veggies are rich in fibre, potassium, antioxidants and vitamins - including immunity-boosting فيتامين C. Carrots also deliver beta carotenes, compounds, which promote healthy skin.

Finally, make sure green is a feature on your Christmas dinner plate - whether this be broccoli, green beans, peas, or sprouts. Green vegetables like these are packed with antioxidants, iron, vitamins and important minerals.

If you have time to make your own bread sauce instead of buying pre-made, this can significantly reduce the calories, sugar and salt content of your festive feast.

For homemade bread sauce, swap white bread and cream for heart-healthy wholemeal bread and skimmed milk. Adding onion, cloves, black pepper and nutmeg are all healthy ways to pack in flavour.

Cranberry sauce will always contain sugar, but if you make it at home, you can use healthier, natural sugars instead of the highly refined sugar found in most shop-bought options.

Gupta suggests replacing tinned cranberry sauce with a healthier homemade cranberry sauce made with natural sweeteners like honey or maple syrup.

"This swap reduces added refined sugars which supports better blood sugar control and insulin sensitivity, reducing related health issues," she says.
