Milk and dairy products:
Dietary partner for life?• High nutrient density
• Reduced consumption in early life is worrying
• Method of production can influence content of some
nutrients
• We don’t know everything………for e.g.
• …..what are the differential effects of butter, cheese,
yogurt, milk etc.?
• …..is fat-reduced milk ‘healthier’ than full fat?
• …. is saturated fat-reduced milk/dairy better than
normal?
• There are lingering issues around prostate (and breast)
cancer
• For most people milk yes, though milk much is understood…..14
