Det kan virke som om dyr oppforet på kraftfor gir dårligere kjøtt og egg.

Sitat:

ANY diet, whether it be high fat - low fat (or anything in-between), if it promotes imbalances in fatty acid profiles, will in the long run have negative health consequences. In the mid '50s, the biochemist, anthropologist, and explorer Hugh Sinclair suggested an alternative explanation for the relationship between dietary fat and cardiovascular disease.
Sinclair noted that several people groups existed that consumed relatively high amounts of fat and yet were free of heart disease.

Sinclair detailed the dietary habits of the Eskimos (previously discussed); the Masai people of Kenya who ate large quantities of ruminant milk and meat; and Jamaicans who ate large amounts of saturated fat in the form of coconut oil. All three groups, all consuming high fat diets, were relatively free from heart disease.

Sinclair suggested that the polyunsaturated profiles of these diets were protective, and concluded that the rise in cardiovascular disease was more related to their exclusion from the diet rather than the inclusion of saturated fats or cholesterol. Since Sinclair's day, our biochemical understanding of fat has increased exponentially. We now realize it is not just the polyunsaturated content of the diet, but the ratio of N-6 to N-3 polyunsaturates that may ultimately determine health.

Both dietary extremes discussed fail to introduce balance in this ratio. High carbohydrate diet due to their high grain and plant content will ultimately be low in N-3 fats (especially long chain N-3 fats - i.e. EPA/DHA), thus unbalancing the N-6/N-3 ratio. Low carbohydrate diets, in their popular form, rely heavily on commercially raised grain-fed meats and poultry (the fatty acid profile of the meat from wild game, free range beef and poultry have a significantly higher N-3 to N-6 ratio), eggs (free range hens also make better eggs) and cheeses.

Jeg foretrekker produkter der dyra får gå fritt, både pga dette og fordi jeg er for et bedre liv for produksjonsdyra. Høns er ofte to eller tre i et lite bur. Der blir som regel en av de plaget og stukket hull på av de andre sine nebb.
