Jan. 13, 2012 -- The health conscious residents of Loma Linda, a small California city with a large Seventh-day Adventist population, have banded together to fight against the opening of the town's first McDonald's.

Nestled in a beautiful stretch of land east of Los Angeles, the 23,000 people who live in Loma Linda enjoy one of the longest life spans in the world -- on average, residents live well into their 80s. Its people are borderline obsessed with fitness and clean living, and they have a healthy population of centenarians to prove it.

So when McDonald's decided to move in, the people of Loma Linda went into red alert. When the issue to approve its opening came up before the city council, the meeting room was packed with outraged residents and health professionals, as if a nuclear waste dump, and not a fast food chain, was coming to town.

But the city isn't just full of fit families, it is also heavily Seventh-day Adventist, a religion that strongly encourages congregants to follow a vegetarian or vegan diet, as well as an alcohol, tobacco and caffeine-free lifestyle.

Pastor Randy Roberts of the Loma Linda University Church says healthy living is dictated straight from the scripture.

"In Corinthians, Paul speaking of the human body says specifically, 'you are the temple of the Holy spirit,'" explains Roberts. "Therefore, he says, whatever you do in your body, you do it to the honor, the glory and the praise of God."

He says the church has not taken an official position on the McDonald's controversy, but stands for living "a balanced, healthy, and whole lifestyle."

Dr. Wayne Dysinger, a physician of preventative medicine and a Loma Linda resident, is a leading member of the community coalition that opposes McDonald's. He says it is not just about the burgers and fries on McDonald's' menu, but also about what the fast food chain represents to Loma Linda's residents who cherish the community's health-conscious history.

"Loma Linda is sort of a symbolic city for healthiness, and McDonald's is sort of a symbolism of unhealthiness," said Dysinger, a Seventh-Day Adventist and father of two. "That's a significant issue. My kids know about McDonald's. McDonald's is the one that sells the toys."

In response to the community opposition, McDonald's said in a statement to ABC News:

"We have been working hard over the past several years to ensure we have options on our menu to meet a variety of dietary needs. For example, our line of Premium Salads can be ordered without meat. We also have other offerings including Apple Slices, Oatmeal and Fruit and Yogurt Parfaits as well as a variety of portion sizes... McDonald's and our franchisee look forward to working with the Loma Linda City Council and residents to hopefully address any questions or concerns. We believe the new restaurant will support the Loma Linda community with a contemporary dining experience and help fuel economic growth."

McDonald's won't exactly be the first fast food chain in town. Though several health food stores are popular with residents, in recent years a handful of chains have arrived, including a KFC, Del Taco, Weinerschnitzel, Baker's Burger, and most notably a Carl's Jr., which also came under intense fire when it first moved in.

Caught in the middle between the health food advocates and the burger eating population, as well as the land developers and those who welcome business growth, is Loma Linda Mayor Rhodes Rigsby.

A Seventh-Day Adventist and a physician himself, Rigsby says he has the desire to promote health, but doesn't feel limiting food choices is an appropriate mandate.

"I don't think it's the government's responsibility, personally, to legislate vegetarianism; I think if everyone became a vegetarian they would probably have a healthier life, but it has to be their choice," he said.

"I would hate to go to a town where vegetables are outlawed because the majority are meat and potato carnivores," he continued, "to me that doesn't make sense either way; I think people should have options."

Dysinger admitted, "I agree that we don't want to legislate health, but on the other hand, we can create healthy environments or we can be oblivious to healthy environments. I believe we have to do everything we can to create a healthy environment."

Mayor Rigsby said that if the citizens of Loma Linda want to ban further fast food development, a ballot initiative enabling residents to vote on the issue might be an acceptable approach going forward.

The small city is a particularly unusual battleground, considering the first McDonald's opened in 1940, just five miles away in the town of San Bernardino. Now the country's most iconic fast food chain has over 33,000 locations worldwide in 199 countries around the globe.

Even though Loma Linda's city council approved the McDonald's development, the residents who are fighting it say it's not a done deal yet. Dysinger said there is enough community opposition that he believes the council will want to reconsider their decision.

"We're continuing to work on this with the developer directly," he said. "We have other restaurants that we feel would be much healthier than McDonald's that we'd like to bring in…we'll do what we can to not have McDonald's in Loma Linda."
