When it comes to milk you should go full-fat, especially with kids

(CNN)Milk has had a bad rap in recent years. A rise in veganism and concerns around intolerance to the creamy white drink has seen a surge in popularity of milk alternatives, and multiple myths still surround the drink, including beliefs that it worsens the symptoms of a cold.

But when it comes to kids, cow's milk is a must-have -- and always in its fattiest form, experts say.
Milk is a good source of calcium, iodine, vitamins A and B12, and fat -- and it's the fat that helps children meet their energy requirements, says Lucy Upton, a specialist pediatric dietician and spokesperson for the Association of UK Dieticians.
"Fat is very important in children," says Upton. "They have very high energy requirements."
The three key energy sources for kids are dairy, protein and carbohydrates, and kids need significantly more energy per pound (or kilo) than adults. "The average two-year-old needs 80 calories per kilogram of weight," she says, highlighting that adults need less than half that amount.
A recent study also found that kids who drank full-fat milk were less likely to be obese than those who drank the low-fat kind, although that insight was solely observational.
So why deprive them of the good stuff when they've got so much energy to consume?
Don't, experts advise, unless intolerance or allergy is a genuine issue -- something that occurs in 2% to 7% of children, Upton says.

You may not have heard of toddler milk, but today it's a widely available product targeting children aged 12 months to three years, marketed as a follow-up drink to baby formula.
Health and nutrition experts have long advised against toddler milks because of their added sugar and salt and lower protein than ordinary cow's milk, which was recently reiterated in a consensus statement released by key US health and nutrition organizations.
But a study published Tuesday found that between 2006 and 2015, toddler milk sales increased by 2.6 times, from 47 to 121 million ounces, aided in large part by increased advertising.
"We found that sales and adverts for toddler milk increased and decreased for formula," said Yoon-Young Choi, a stati
