Healthy Meat Analysis


Shetland lamb and beef: key nutrients analysis and comparison with data from conventional and organically reared sources.

Lamb
Samples of lamb were taken from animals born and reared on the Uradale farm in Shetland. These were compared to existing data referred to in a recent report from the Food Standards Agency that compared organic and conventional foodstuffs. (http://www.food.gov.uk/multimedia/pdfs/organicreviewappendices.pdf).

It was found that for the samples analysed, Shetland lamb had a higher level of the so called, “healthy fatty acids” - omega 3 and omega 6.

This corresponded to higher levels of total fat (and total fatty acids) in each sample. Uradale lamb had 23.2 % fat while the FSA referenced lamb had an average fat content of about 14%.

However, even taking this difference in fat content into consideration the samples from Shetland lamb showed higher levels of omega 3 and omega 6 fatty acids than samples from both organic and conventionally reared lamb from an FSA referenced study.

Beef
Compared to published data on organic and conventionally reared beef the Uradale beef samples analysed had higher levels of a number of key nutrients including iron, zinc and the so called “healthy fatty acids” omega 3 and omega 6.

Significance of the data
This study was not conducted under scientific conditions and proper controls and standards were not included in the process. Moreover, only a small number of samples were taken for the lamb analysis and the beef analysis was from a single animal only. Therefore the data cannot be regarded as robust or statistically significant and all that can be said at this stage is that the results may warrant further investigation.
