With so much attention to excess sugar and fat in children’s diets, Warren Shaw of Shaw Farm in Dracut knew it was time to make some changes. The 100-year-old dairy farm he runs, with a herd of cows raised without growth hormones, now sells Lighten Up! Chocolate Milk ($1.65 to $2 for a pint; $ 4.19 to $5.50 for a half gallon). It is made with 1 percent low-fat milk and about one-third less sugar than regular chocolate milk. One cup has 150 calories (slightly less than other low-fat chocolate milks), and it’s farm fresh from a small dairy. You can feel good about buying local. Available at Shaw Farm’s store, 204 New Boston Road, Dracut, 978- 957-0031; Wilson Farm, 10 Pleasant St., Lexington, 781-862-3900; Verrill Farm, 11 Wheeler Road, Concord, 978-369-4494; and Kickass Cupcakes, 378 Highland Ave., Somerville, 617-628-2877.
