Jo Travers tells co-presenter Matt Tebbutt: "Lard has actually quite a lot of the monounsaturated fats, and that is the heart-healthy fat.
"Those kind of fats we actually need in our diets and it has much more in fact than butter does."
She adds: "When you get down to it, there's nothing actually wrong with including lard in your diet."
However Jo also reveals that not all lard is created equal and hydrogenated lard can contain unhealthy trans fats.
She says: "Commercially produced lard that you often get in a supermarket, the fat profiles are quite different."
Matt warns that if lard has "hydrogenated" on the label, it is best avoided.
He advises sourcing high-quality lard from a farm rearing free-range pigs.
Lard has fallen out of favour with the British public, ever since research in the 1950s linked its high saturated fat content to heart disease.
It is also intensely calorific and contains 20 per cent more calories than butter on average.
However lard is in fact one of the richest sources of vitamin D and has 50 per cent more of the vitamin than butter, particularly if it is sourced from free-range pigs.
