why do we drink milk from cows
a year, but 40% of that is poured on to cereal. The definition of what an average person is seems to include 60% who are children. But what was once touted as the one-stop supplier of most nutrients is going out of fashion Б
and in the UK dairy. Milk is increasingly getting a bad press. What gluten intolerance did for bread, lactose intolerance is doing to milk. : БMaybe people are drinking less milk because it is poisonous to many of us. Б The solution Lactose is the sugar found in milk and dairy products and it needs the enzyme lactase to break it down. Without enough lactase, the lactose is broken down by bacteria in the small bowel, causing bloating, flatulence, stomach cramps, diarrhoea and nausea. Globally, around 70% of us donБt continue producing lactase after we have finished breast or formula feeding. Genetically, babies need milk Б adults not so much. But northern Europeans, who thousands of years ago got into cattle farming, have adapted to cowБs milk and have a genetic mutation so that only between 2 and 15% have a degree of lactase deficiency.
This rises to 23% in central Europeans and 95% in Asian populations. So is lactase deficiency the normal state? Not really Б it made sense to drink milk at one time, so we adapted to do so. And cowБs milk is nutritious Б it contains calcium, vitamins A and D and riboflavin, as well as protein and isnБt heavy on calories. Dr Miranda Lomer, senior consultant dietitian in gastroenterology at GuyБs and St ThomasБ NHS Foundation Trust, says our bodies may find the calcium in cowБs milk easier to extract than from the supplements in almond and coconut milks (which are generally less nutritious). Lomer also points out that lactase deficiency does not equal intolerance and even people with can still usually drink milk in tea (around 50ml) or on cereal Б between 250 to 375ml a day. You can see your GP for a lactose breath test, but Lomer suggests drinking a large glass of milk. If you get bloating, gurgling and diarrhoea within the next 24 hours, you should consider yourself intolerant. But you may still be able to have milk in cereal and tea.
People may have ethical issues about exploiting cows for their milk, but it isnБt true to say we arenБt meant to drink it Б because in northern Europe, we are genetically modified to do so. Each week, we ask you to share your questions about farming, food or Sacrewell with us on Facebook. The person who writes the best question wins a free tractor ride for a child and accompanying adult, as well as having their question answered on our website. This question came fromб Elowen, Emily DoidgeБs daughter. ItБs difficult to milk a pig! Cows, sheep and goats have udders, and can be milked by hand into a bucket. In comparison, pigs have up to 14 small teats, where they eject the milk for only fifteen seconds at a time (the ejection time of a cow is well over ten minutes). Getting even such a small amount of milk requires enormous dexterity, skill and speed. БWhen sows are lactating, they get very aggressive. They re not docile like cows. They re smart, skittish, suspicious, and paranoid.
Б Edward Lee, the chef and owner of 610 Magnolia, has been experimenting with making cheese from pig milk. He managed to get a few jars of pig milk by creeping up on the sows whilst they were sleeping, frantically pinched at their tiny nipples, then ran away when they woke up. There isnБt a pig milking machine because the demand to make one isnБt there, and because milking a sow by hand is incredibly difficult itБs not very popular. Pig milk:б itБs expensive Sows produce on average only 6 litres of milk a day, whereas a dairy cow can produce anything from 20 45 litres a day depending on the breed. Given the amount of milk that would be needed to make money on some pig cheese compared to the amount of care and cost associated with raising and maintaining a sow for milk (which does not produce a great deal of milk anyway), it isn t very economical. A family-run farm in the Netherlands has produced the world s first and it sold for бе1500 a kilo, although due to the huge numbers of man-hours required they said that it was probably a one-time thing.
What does pig milk and cheese taste like? Pig milk, at eight and a half percent butterfat, is exceptionally rich and the proportions of components like water and lactose are like those of cow milk. Lee managed to make some ricotta from the pigБs milk which he said was БdeliciousБ, and in Italy thereБs a pigБs cheese called. The farm in the Netherlands described the pig cheese as Бchalky and a little bit salty and compared to other cheeses saltier and creamier, yet grainier. For now, it doesnБt look like pigБs milk or pigs cheese is on the table in the UK. In other cultures, dairy products come from a range of animals including camels, water buffalo, horses and yaks. In the West, goats, sheep and cows have been domesticated between 10,000 B. C. and 8000 B. C. and all three have since been bred to improve temperament and output. We really likedб which explains why these three animals in particular were so popular in the dairy industry, and goes into much more detail about dairy animals from other cultures. References
