Producing and eating meat
6 important questions on Producing and eating meat
Iron in meat (high bioavailability)
- Main reservoir as component of heat protein myoglobin
- Iron deficiency (anaemia) most common nutritional deficiency in world
- Team iron much more easily absorbed from gut than non-heat iron
- team iron improves absorption of non-heat iron
Concerns about eating meat are [nutritional value of meat]
- Carbohydrates
- fibre
- Vit C
- Vit K
- Meat purchased by consumers usually has relatively high fat content
- Fat = excellent energy source
- Early -> hunter-gathers this was favourable (high fat > high energy)
- Today -> less so for health-conscious consumers
- Trend -> reduce amount of carcass fat in animals
Animal products can be a potential source of serious food-borne bacterial infections, namely
- Salmonella
- Campylobacter
- E. Coli
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
BSE (Bovine spongiform encephalopathy) =
- Neuropathological disease
- Spread by feeding protein supplement derived from waste material produced as by-product of the slaughtering industry
- Variant Creatzfeldt-Jakob disease (vCJD) - rare brain disorder
- SA & china classified as 'high risk' - because not testing for BSE
How can we balance the negative concerns about meat production & consumption by positive considerations?
- Certain areas & soils are unsuitable for growing crops useful to humans
- animals can be used to exploit these areas indirectly
- Meat production is associated with larger range of other valuable by-products
- skin, leather, wool, feathers
- Large part of beef eaten in EU comes directly / indirectly from dairy herd - main objective to provide milk
- Generally, as wealth of group increases so does meat consumption
- Reason most people eating meat = enjoy eating meat
Why is meat healthy & unhealthy at the same time?
- Major benefits form including in diet
- contrast: major health concerns with eating too much fat (saturated fat)
- Animal products like meat = major source of saturated fat - also dairy
- Dairy industry has addressed problem by developing low-fat alternatives
- Initiatives such as the EU Green Deal - for making EU the first climate neutral continent in the world
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
