Princes is about to embark on a PR campaign to promote the potential male fertility benefits of corned beef. This is on the back of a study that suggests that vitamin B3 and zinc ­ which are both prominent in corned beef ­ can help boost fertility. Meat marketing manager Hazel Grennan said: "We are looking to compile a library of real life case studies which illustrate the beneficial effects of corned beef on the fertility of men so we are inviting men to write to us with their stories." In the meantime, Princes will run new ads later this month to promote corned beef to men. This is part of the consumer campaign under the Best Before' theme that Princes is currently running. Advertisements will appear in lifestyle magazines such as Loaded and FHM, and the campaign will also provide recipe ideas for men that contain corned beef. {{P&P }}
