Evening
@Step hen and welcome to the forum.
It's crucially important to eat the right kinds of healthy fats. Anybody prescribed a low fat diet for 12 months, will tell you their skin and nails suffered and very often their hair falls out. These are the external effects that patients notice. Goodness knows what damage occurs on the inside!
You won't go far wrong if you maintain a healthy weight and have plenty of protein foods, non starchy vegetables and healthy fats. What ever you do, avoid ultra processed products and trans fats. Trans fats (otherwise known as partially-hydrogenated oils) are considered the worst fats to eat, whatever your medical history.
Instead, choose oily fish like salmon, tuna, mackerel, herrings, sardines including pilchards, trout or anchovies at least twice a week and stick to cold pressed oils like extra virgin olive oil and avocado oil. All kinds of nuts are helpful too.
Avoid industrial seed oils like sunflower oil. There's nothing wrong with sunflower hearts
per se, but industrial manufacturers use high temperatures, mechanical pressure, chemical deodorizers and petroleum-based solvents to extract oils from seeds. This effectively strips the oil of nutrients and antioxidants while creating harmful trans fats. Butter is OK, but avoid margarine which is also high in trans fats.
