Bacon sales in the UK are declining as consumers become more aware of the potential health risks associated with nitrites, a controversial additive used in traditional bacon curing. Nitrite-free bacon sales are on the rise, indicating a shift in consumer behavior towards healthier alternatives. The use of synthetic nitrites in bacon production has been linked to cancer and other health issues, prompting calls for stricter regulations and warnings on processed meat products.

In addition to health concerns, the production of bacon also raises issues regarding animal welfare and environmental impact. Factory farming practices for pigs involve inhumane treatment, while the industry contributes to climate change, deforestation, and pollution. As consumers become more aware of these issues, there is a growing trend towards plant-based alternative proteins as a healthier and more sustainable choice.
