It's been claimed that it can help reduce the memory loss associated with Alzheimer's, improve skin and even boost weight loss and help lower cholesterol. But caution should be exercised in how much you use coconut oil in your diet.

Coconut oil is oil taken from the dried fruit produced by the coconut palm tree. When buying coconut oil you'll see terms like 'virgin' and 'cold pressed'. The term 'cold pressed' meant that the oil has been extracting using machinery rather than heat methods. The term 'virgin' usually refers to it being unprocessed – that is has not been bleached, refined or deodorised. Although there is no industry standard for the term, unlike olive oil.
The basis for the claims are that coconut oil contains high levels of a saturated fatty acid called lauric acid, which is what is known as a medium-chain fatty acid (or MCFA). Compared to long-chain fatty acids (LCFAs) found in other oils, these are considered to be a healthier type of fat. This is because they are more easily absorbed and burned by the body for energy, compared with long-chain fatty acids. These medium-chain fatty acids also appear to be stored differently to long-chain fatty acids, which are stored in the adipose tissue.
Over the last few decades there have been a number of studies on the benefits of coconut oil and medium-chain fatty acids.
Despite these small studies showing slight benefits to waist size, there is a lack of evidence to suggest long-term weight loss or any significant improvements to Body Mass Index (BMI). According to the Mayo Clinic, while some short-term studies have suggested MCFA's don't raise low-density lipoproteins (LDL) or what is known as 'bad cholesterol', there are limited long-term studies into the impact coconut oil can have on your heart health.
They also highlight how coconut oil is highly calorific, which can signal to your body that it should store more fat. They highlight that even if the stored fat doesn't come from the coconut oil directly, high consumption of it could indirectly encourage fat storage and have the opposite effect of what you're trying to achieve.
Heart UK released a statement in response to media coverage on the benefits of coconut oil, urging caution in its overuse or its aid as a dietary supplement. They highlighted how coconut oil contains approximately 85% saturated fats, which has the potential to raise your overall cholesterol and your low-density-lipoprotein levels. This is extremely high, considering that butter contains 63% saturated fat, and olive oil contains 14% saturated fat. It means that by consuming just two tablespoons of coconut oil in a day, you would be consuming 24g of saturated fatty acids, more than your entire recommended daily allowance for a female, which is 20g per day.
While consuming coconut oil in moderation as part of a healthy balanced diet is fine, there is no long-term research to suggest any extraordinary benefits from switching to coconut oil in terms of weight loss. Studies on small scales have shown some benefits to waist size, but not to overall BMI. Heart UK still recommend that to reduce your weight or your cholesterol levels, you should avoid cooking with coconut oil and you should not use it as a dietary supplement.
For long-term weight loss a healthy balanced diet combined with regular exercise is still the most beneficial approach. This should include:
