The 198 riders who start each Tour de France are some of the fittest athletes on the planet, and they have to consume an impressive number of calories each day to fuel their bodies in the three-week race.
They have to chow so much that eating actually becomes work, and by the third week chefs have to get creative when preparing healthy but delicious meals.
Still, there are just some foods and drinks that Tour chefs will almost never serve riders.
Given modern cycling's obsession with sports science and nutrition and marginal gains, many cyclists won't see certain items at the team's breakfast or dinner table.
Olga Belenka and Sean Fowler, chefs for the American Cannondale-Drapac team, shared with Business Insider the foods and drinks they avoid serving their riders. The cyclists may consume some of these items on their own, but never at Belenka and Fowler's table, where the athletes eat all their meals. Like all chefs, they have strong opinions!
"Since the beginning, we've been gluten-free, lactose-free, and white-sugar-free," Fowler says. "I continue that diet, but the riders do still sometimes have that — just not from me."
Here are the six things Cannondale-Drapac riders are almost never served during the Tour.

Pork
"Pork is too heavy and hard to digest," Belenka tells Business Insider.
"We just never cook pork. In the morning, we have omelettes with chicken or roasted turkey breast."
Occasionally, they will make an exception and add some ham to the omelettes.
Many pork products are high in fat, which means they take time to digest, like beef.
Milk
Fowler gets passionate when he talks about milk. "There doesn't exist in today's market, anywhere — unless you have a cow in your house — milk that's nutritious," Fowler tells us. "Milk is dead white water that's been fortified. There is no beneficial bacteria."
"And most dietitians implement a lot of dairy into the diet exclusively for the protein — and they don't consider all the bad things. There's all sorts of bad things in milk."
While Fowler is anti-milk, in general research shows that milk is a good source of protein and an effective hydration source. Some small studies show that it can improve athletic performance and is an effective recovery beverage. But in some people, especially those with lactose intolerance, dairy products can cause digestive issues.
White sugar
Like many health-conscious people these days, Fowler and Belenka say they avoid using white sugar altogether.
"Maybe we'll use brown sugar from time to time, but it's always less than what most people would use," Fowler says. "Agave syrup is a substitute once in a while. When we make something sweet for the riders, we try to do 50% fructose and 50% glucose."
Belenka adds: "Generally we try not to do too many sweets. Even making cakes, I try to use bananas, dates, and other options for sweetness."
As Business Insider's Erin Brodwin has reported: "When we eat large amounts of sugar and don't balance these calories with those from protein and fat, which the body breaks down more slowly, it can lead to dramatic rises and drops in blood sugar. These 'crashes' can cause 'hanger,' or what's known as being angry and hungry at the same time."
