What did studies of Dairy product intake find?

Studies of Dairy product intake measured 3 outcomes; the most studied are body composition (1 study), physical function (1) and muscle strength (1).

Body composition

1 study

Dairy product intake showed no clear effect on body composition in humans (Added to home-based resistance training versus home-based resistance training alone).

What is Dairy product intake linked with?

Studies link Dairy product intake with 1 measure, most often sarcopenia (1 study).

Sarcopenia

downin humans1OR 0.42

1 study

Dairy product intake is linked with a lower risk of sarcopenia in humans (adjusted model) (OR = 0.42, p = 0.049).
“dairy product intake (OR = 0.42, p = 0.049), body mass index (BMI) (OR = 0.77, p = 0.019), and marital status with widowed (OR = 0.31, p = 0.005) were significantly associated with sarcopenia.”

Dairy added no overall exercise benefit in older adults

In a 12-week randomized trial, adding dairy protein to home exercise offered no overall advantage among 54 Japanese adults aged 65 or older.In a 12-week randomized trial, adding dairy protein to home exercise offered no overall advantage among 54 Japanese adults aged 65 or older.
