NEW YORK, March 11 (Reuters) - Bel Group, the French company famous for cheese snacks like Babybel and Laughing Cow, broke ground on Wednesday on a $200 million project to double capacity at its Brookings, South Dakota, Babybel plant, moving to meet healthy snack demand from weight-loss-drug users and other health-conscious Americans.

The investment, which will create 150 new jobs, will help Bel to meet rising demand for healthy, protein-rich snacks from customers in the U.S., which accounts for about one-third of Bel's sales, said Peter McGuinness, CEO of the company's North American arm. "If we did not act now, we would be squandering growth and running up against capacity constraints," McGuinness said in an interview.

The investment comes as consumers grow more conscious of the nutritional value of snacks, a trend bolstered by the rise of GLP-1 drugs from pharma giants like Novo Nordisk and Eli Lilly. 

In January, President Donald Trump's administration issued new guidelines recommending Americans eat more protein and less sugar, part of Health Secretary Robert F. Kennedy Jr.'s "Make America Healthy Again" movement.

Bel has expanded the line of wheel-shaped, portion-sized cheese snacks known as Mini Babybel to include gouda and mozzarella versions, and created a new version with more protein and probiotics that McGuinness said is well-suited for GLP-1 users. "The product delivers on GLP-1 (needs)," he said. "We're getting a definite impact from that."

The Brookings plant, which now churns out around 1.6 million Babybels a day, will soon produce more than 3 million, he said. 

McGuinness said the company for now is focused on growing internally, but may eye acquisitions in the future if demand continues to rise.

While the White House has claimed credit for Bel's and other companies' U.S. investment in the wake of Trump's tariffs, McGuinness said the Brookings expansion was long-planned, and has "nothing to do" with tariffs.

McGuinness told Reuters the company works primarily with three dairy producers near the Brookings plant. Though farmers have faced higher costs for agricultural materials like fertilizer, McGuinness said Bel's high volume of orders keeps prices manageable.

Bel, which has four plants in the U.S., has undertaken other expansions of late, including a roughly $140 million expansion of a plant in Nampa, Idaho, that makes GoGo squeeZ snacks.
