Milk is a good thing and we should drink more of it. This has been a
prominent health message ever since the 1946 Education Act ensured that school children were given free milk. But in recent years, the debate has shifted to which type of milk is best. This week, it took an unexpected turn when researchers
claimed that it might pay to note what the weather was doing when the
milk was produced. A study, published in this month's Journal of Dairy
Science and led by researchers at Newcastle University,
showed that "wetter, cooler summers can have a detrimental effect on
the milk we drink". A poor summer meant that milk had a "significantly
higher saturated fat content and far less beneficial fatty acids"
compared to that produced in a regular year.
