A meta-analysis (where a collection of related studies are combined to greatly increase the statistical power) of investigations looking at the effects of dairy products on human health has seemingly torpedoed the simple claim that consumption can be linked to heart attacks and strokes (https://www.theguardian.com/society/2017/may/08/consuming-dairy-does-not-raise-risk-of-heart-attack-or-stroke-study). This might be somewhat embarrassing to nutritionists and other health professionals who generally recommend people to switch, where possible, to 'low fat' alternatives for milk, yoghourt and cheese. It might not protect them from heart attacks but doing so would at least tend to reduce calorie intake (fats are high calorie) and counter tendencies to become obese. There is a substantial industry generating ranges of low fat food products. Personally, I like a bit of regular cheese along with my butter!
