Why do dairy consumers die sooner and have more bone fractures?

Dairy is high in galactose, which is used by researchers to accelerate aging in lab rats, for one.

 

The accelerated D-(+)-galactose-induced aging model is widely accepted; it is based on metabolic theory, and presents many aspects similar to the natural aging process [9]. In the body, D-(+)-galactose is oxidized by galactose oxidase to form hydrogen peroxide (H₂O₂). In addition, this monosaccharide can react with amine groups in various proteins, forming advanced glycation products, and promoting oxidative stress [10]. Recent studies have demonstrated that chronic administration of D-(+)-galactose also leads to immune system dysregulation, sex hormone deficiencies, increasing inflammatory cytokine levels, cellular apoptosis, and diminished total antioxidant capacity [10, 11]. Taken together, these effects mimic aging and impel the subject toward development of age-related diseases [12].

 

 

 

Milk contains a lot of galactose indirectly, because lactose breaks down into glucose and galactose during digestion. In whole or reduced-fat cow’s milk, the measured free galactose is usually near zero to about 0.02 g per 100 g, while the total galactose equivalent is about 2.3 to 2.6 g per 100 g of milk.bmj+1

Practical amount

A typical glass of milk around 200 mL contains roughly 8.5 to 9.3 g of lactose, which corresponds to about 4.3 to 4.7 g of total galactose equivalents after digestion.stud.epsilon.slu

What about cigars by boxes and bourbon by shopping carts? Do they accelerate aging as well?
