Roasting is been listed on the list of unhealthy cooking methods. But is roasting healthy or unhealthy food preparation method? To be specific, is roasting beef healthy? is roasting nuts unhealthy? Let us see what reports say.

One study, was carried out to find how roasting affected the composition of hazelnuts, almonds, macadamia nuts and walnut. The nuts were examined before and after roasting at different time and different temperatures. They found that fatty acid compositions were not affected by roasting and tocopherol isomers were reduced after roasting in hazelnuts.

The same study also proved that increasing roasting temperatures causes the formation of significant amounts of acrylamide only in almonds. Surprisingly, this report concludes that the saturated fatty acids (SFA) in almonds is high affected by roasting and frying.

Tips how to roast healthily

Take some extreme caution when roasting vegetables

Point 1) Choose cooking oil, which is high in calories, fat and has higher smoke point. For example, refined, olive and coconut oils have high smoke point and would not burn easily.

Point 2) Practice low temperature roasting. Keep the temperature well below the oil’s smoke point, (when the oil starts to burn). That’s about 410 degrees for extra virgin or unrefined olive oil. At 350F, roasting can take up to 30-40 minutes to give desirable roasting flavor.

Point 3) Avoid Overheating the oil as it breaks down the nutritional composition of the oil, changes the flavor and releases harmful free radicals. Besides, burned oil produces crispy charred vegetables with little nutritional benefits.

Point 4) Salt the vegetables after roasting them. This helps to lower the smoke point of oil.

Point 5) Don’t cover your vegetables when roasting them in the oven. This avoids steaming them instead of browning.
