Grass-Fed Meats

In The Netherlands it isn't very common (yet) to refer to meats as either grain-fed or grass-fed, so if you are looking to buy grass-fed meats, this requires a bit of research.
The Dutch term is "grasgevoerd", but you won't find this term in the supermarkets.
Even of meats that are organic, cannot be safely assumed that the animal was grass-fed.
Organic with regards to the feed of the animal only guarantees that the food does not contains any hormones & antibiotics.

Why eat grass-fed meat?
Cows are meant to eat grass and grass only, period. Their digestive system is complex, and just as with humans, putting the right fuel in, will also result in a better outcome.
(we highly recommend watching Food Inc. by the way)

Grass-fed meat is higher in omega-3 (up to 6 times higher). Omega 3 is good for you. Grain-fed meats are higher in omega-6.

Grass-fed meats don't contain hormones or antbiotics.

Grass-fed cow = happier cow.

What about Irish beef?
It's not a guarantee that Irish beef is 100% grass-fed, since it is possible some grains will be added to their diet in winter.
Accoding to their website, Albert Heijn claims to sell Irish beef in the "Puur & Eerlijk" line, but that the animals do get fed grain on occasion.
Vomar sells Angus beef, but no info on their website is found whether it's 100% grass-fed or not.
