Poor olive harvests last year may mean a shortage of olive oil . Dietitian Dr Sarah Schenker offers some alternatives : . Poor olive harvests last year may mean a shortage of olive oil - so here are some alternatives . Best to roast veg : Rapeseed . Rapeseed oil has 6 per cent saturated fat compared with olive oil 's 14.3 per cent . It also has ten times the amount of omega-3 fatty acids and 50 per cent more vitamin E. EXPERT VERDICT : One of the healthiest oils , with a subtle , grassy taste . One concern with heating oil is how soon it starts to smoke . This is when the fatty acids in it oxidise , creating harmful free radicals . Rapeseed oil has a high smoke point , so use for frying or roasting . Best in risotto : Rice bran . Taken from the bran ( the vitamin-rich layer below the fibrous hull of rice ) and germ ( the oily , nutrient-rich part of a rice grain ) . High in protective antioxidants such as vitamin E. EXPERT VERDICT : As well as heart healthy vitamin E , this contains ferulic acid , which has powerful anti-oxidant and anti- inflammatory effects , helping to protect the immune system and prevent disease . Coconut oil makes great stir-fries . Best in stir-fries : Coconut . Extracted from the white flesh of coconuts , this is almost 50 per cent lauric acid , a 'healthier ' saturated fatty acid . Solid at room temperature , so ca n't be used for salad dressings , but its high smoke point makes it ideal for cooking . EXPERT VERDICT : Though it 's 86.5 per cent saturated fat , research suggests the saturated fat in coconut may be used up more quickly by the body and is less likely to be stored as body fat . However , use in moderation . Best on salad : Walnut . With useful amounts of fatty acids , walnut oil may help lower heart disease risk . A distinct walnut flavour and low smoke point , so best for dressings . EXPERT VERDICT : Delicious , but not particularly versatile . Buy small bottles and keep in a cool , dark place as it goes rancid easily . Best for baking : Hemp seed . Richer in the essential fatty acids omega-3 , 6 and 9 than other culinary oils , and has half the saturated fat of olive oil . One tablespoon provides 94 per cent of your daily recommended intake of omega-3s . EXPERT VERDICT : Versatile - can be used for stir-frying , dipping and salad dressing . One of the healthiest alternatives to olive oil , though the flavour may not be to everyone 's taste . Disguise with dried fruit and spices . Rapeseed oil ( l ) , walnut oil ( c ) and hemp seed oil ( r ) are all good for different dishes .
