Dairy and its potential link to acne continues to be debated and
now a recent US study has found it’s the type of milk teens drink that may
affect their acne.
The study found no relationship between the consumption of full fat
milk and acne in the 14-19 year olds.
However teenagers who drank low fat or skim milk regularly were
more likely to have moderate acne than other teenagers.
Interviews with the teenagers found no other significant differences
between their diets such as total dairy intake, saturated or trans fat intake,
total energy intake or glycemic load. Similarly, there were no differences in body
mass index between the two groups of teenagers.
The study supports other evidence that skim milk may be more
problematic than regular milk for teens with concerns about their skin.
However it is not clear whether processing regular milk removes
protective factors along with the milk fat or simply concentrates constituents
in milk that can promote acne.

consumption results in a significant increase in insulin and a growth factor
known as IGF-1, which can stimulate oil production in the skin.
not surprising that components in cow’s milk or our metabolism of them can
interfere with the delicate balance of hormones in some teenagers,” she said.
“However milk is
an important source of calcium and protein in a teenager’s diet so we would
certainly not recommend removing it without good cause or discussing it with
your doctor first.”
For people with
acne, All About Acne currently recommends a low glycaemic index (GI) diet
protein-rich foods such as meat, nuts and legumes
· a wide range of fruits and vegetables
· complex carbohydrates such as wholegrain breads and cereals.
