No, vegans are not extraterrestrials from a planet orbiting Vega, although many might consider their dietary habits to be completely alien. Plant-only eaters represent a mere 2 percent of the population; another 5 percent describe themselves as vegetarian.
In contrast, Americans are noted for their penchant for overconsumption of such animal-based foods as meat, eggs and dairy along with high sugar intake. More than two-thirds of Americans are overweight or obese, with more than a third having diabetes or metabolic syndrome. A poor diet is a risk factor for type 2 diabetes, which carries with it a number of serious and life-threatening complications. Family history, low activity and excess body weight also increase a person‘s chance of getting the disease.
The “vegan” term can connote an animal-rights ethic and environmental activism, but the common denominator among all vegans is avoidance of all animal-based foodstuff.
What might sound crazy to some, a diet completely devoid of steaks, eggs, cheese and ice cream has an ally: science.
There are no guarantees, but evidence continues blooming that a daily diet based on whole plant foods can prevent or reverse many of the chronic health problems plaguing America -- hypertension, high cholesterol, heart disease and type 2 diabetes. There’s further evidence that a plant-based diet also can help prevent or fight cancer, autoimmune diseases and arthritis, among many other common conditions.
What are the differences between a vegetarian and vegan diet?
Nutrition science prefers discussing a whole-plant-food diet, rather than a vegan one, to eliminate connotations of animal-rights or environmental ideology. But there‘s little debate that diets limited to vegetables, fruits, nuts, beans, spices and herbs are healthful. They increase fiber intake that’s lacking in the large majority of American diets, while providing a wide range of antioxidants, minerals and other nutrients, which build the immune system, reduce inflammation and improve metabolism and gastrointestinal health. The diet also reduces or eliminates the intake of processed foods, empty calories and carcinogens.
Up to 50 vegans responded to a Post-Gazette Facebook request, with many advocating animal rights. But many also said they experienced notable health benefits as a welcome side effect, including dramatic weight loss. The diet also helped individuals to reverse osteoarthritis, autoimmune disorders, colitis or Crohn‘s disease, multiple sclerosis and cancer and bring sugar levels back to normal for those with type 2 diabetes. Others say their plant-based diets increase their energy levels, eliminate allergies and improve their skin, including eliminating acne.
“I will never not be a vegan,” said Ellie Gordon, 28, of Squirrel Hill, a vegetarian at age 11 and vegan for seven years. “There have been so many scientific studies and research connecting longevity and alleviation of a whole plethora of health problems with a plant-based diet. There is a whole lot of research to support it even if people don’t care about it.”
Concerns about sufficient protein and amino acids are common complaints against the vegan diet. Several plant foods, including soy and hemp seeds, are complete proteins, containing all the essential amino acids. Eating a variety of protein-based vegetables -- including leafy greens, nuts, seeds and beans -- throughout the day can, in combination, provide the needed amino acids. In a study published in 1999 in the medical journal Medical Hypotheses, researcher Mark F. McCarty explained how vegetable protein reduces the risk of cancer, cardiovascular disease and obesity. His work in the field is often cited in discussions of the benefits of vegetable protein. Mr. McCarty is also co-founder of a mail-order nutritional supplements company, NutriGuard Research.
Scott Jurek, one of America‘s most notable ultramarathoners, became vegan in 1999 because of poor nutrition affecting him and others he knew. German strongman Patrik Baboumian, who holds various world weight-lifting records, also is vegan. They say their success proves that the vegan diet is good for muscles and fitness.
“Don't listen to those self-proclaimed nutrition gurus and the supplement industry trying to tell you that you need meat, eggs and dairy to get enough protein,” Mr. Baboumian told greatveganathletes.com. “There are plenty of plant-based protein sources and your body is going to thank you for stopping feeding it with dead-food. Go vegan and feel the power.”
Kathryn Spitz Cohan of Forest Hills, who directs JFILM, The Pittsburgh Jewish Film Forum, had been vegetarian for three years when she was diagnosed with an aggressive form of breast cancer, which required her to undergo eight rounds of chemotherapy, rather than the traditional four, along with radiation therapy. She and her husband, Jeffrey Cohan, who directs Jewish Vegetarians of North America, became fully vegan during her treatment. He is a former Post-Gazette reporter.
One benefit of her diet and exercise regimen that included power yoga, was maintenance of energy levels during chemo. The couple climbed the steepest side of Acadia National Park’s highest mountain in Maine during her treatments, she said. The diet and exercise regimen seemed to work. In followup tests, her radiologist told her there were no signs of cancer, not even a shadow of the former tumor. It was the most complete response to treatment her doctor had seen, Ms. Spitz Cohan said.
The vegan diet ”was absolutely essential“ to her good outcome with breast cancer, she said.
”It’s been four years,“ she said. ”I can‘t say I’m out of the woods or that it will not come back. But I know I‘m doing everything in my power to lead a healthy lifestyle, and it feels good. I don’t feel I‘m denying myself anything or restricting my life. I love the food. The food is delicious.“
Many Americans believe the more protein the better. But a study published in March in Cell Metabolism found that “a low protein diet during middle age likely is beneficial to prevention of cancer, overall mortality and possibly even diabetes,” and “a diet in which plant-based nutrients represent the majority of food intake is likely to maximize health benefits in all age groups.”
The study authors had found an association between high-protein diets -- “a significant portion” associated with animal-based protein -- and deaths from cancer and other causes. So although the study also found that those 65 and older should get moderate- to high-protein intake, it says their focus should be “preferably mostly plant-based consumption to allow the maintenance of a healthy weight and protection from frailty.“
The most noncontroversial statement in food science is that people should eat more fruits and vegetables.
“No diet won‘t agree with that,” said Michael Greger, physician and director of public health and animal agriculture at the Humane Society of the United States. Also founder of NutritionFacts.org, he reviews 12,000 health studies a year to keep track of nutrition science. “It not only can prevent but it also can reverse heart disease, type 2 diabetes and hypertension. Overwhelmingly it is the diet most associated with chronic-disease prevention and reversal of most of the diseases plaguing the Western World.”
On average, he said, vegans are 36 pounds lighter than omnivores and feature the lowest rates of cataracts, hypertension, diabetes and obesity. The Adventist Health Studies from 1958 to the present and involving 96,000 people (including 4,000 vegans and 20,000 vegetarians) are often cited as providing the clearest evidence of health advantages from plant-based foods.
The study, Dr. Greger said, has shown that vegans have the best health outcomes, followed by vegetarians. Health benefits progressively recede with increased percentages of animal-based foods. Publicity about plant-based health advantages is working. Meat consumption has dropped 12 percent in the past five years.
But while all vegan diets eliminate meat and dairy, not all vegan diets are healthy. “Potato chips, Oreos and Twinkies are all vegan,” Dr. Greger said, explaining why nutrition scientists emphasize a whole-plant-food diet rather than a vegan one.
The Academy for Nutrition and Dietetics (formerly American Dietetic Association) says appropriately planned vegetarian or vegan diets are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. It also said such diets can meet current recommendations for all nutrients, including protein, B-12 and various minerals that previously raised concern about vegetable-based diets. But the association advises people to assess the adequacy of plant-based diets and seek help from nutrition professionals about specific nutrients, food purchasing and preparation, to make dietary modifications that meet individual needs.
In a March article, The Atlantic magazine recruited David Katz of the Yale University prevention research center to analyze many diets, including the vegan, Mediterranean and Paleolithic diets, to determine the healthiest. None was declared the winner. The Mediterranean diet features high consumption of vegetables and olive oil with moderate protein consumption. The Paleolithic or caveman diet tries to emulate what our ancestors ate -- meats, non-starch vegetables but no grains or processed foods from modern agriculture.
But a whole-plant-food diet won by default. Dr. Katz concludes that ”among the salient points of proven health benefits the researchers note, nutritionally-replete plant-based diets are supported by a wide array of favorable health outcomes, including fewer cancers and less heart disease. These diets ideally included not just fruits and vegetables, but whole grains, nuts, and seeds.“
In 1990, Robert Conti was diagnosed with multiple sclerosis, which eventually caused him numbness in his shoulders and the near-shutdown of his bowels and urinary tract. During a hospital stay, he recovered bowel and urinary function by adopting a steamed-vegetable diet.
Once released from the hospital, he enrolled in the John McDougall course at what‘s now known as the McDougall Wellness Center in Santa Rosa, Calif., which advocates a dietary foundation of starch-based foods -- potatoes, corn and rice -- with whole vegetables and no oils. The diet is 100-percent vegan.
In following months, Mr. Conti, now 56, of Scott, regained movement and sensation, with added help from exercise. Today he said he has no signs of multiple sclerosis -- his doctor could no longer detect plaque on his spinal cord. That and his lack of symptoms convinced his doctor to change his diagnoses to atypical multiple sclerosis, Mr. Conti said.
Without the diet, he said, ”I think I would be using a wheelchair for mobility and eventually require communication aids.“
Many adopt a vegan lifestyle to advance animal rights. That was the motivation for Ashley Frohnert, 24, of Friendship, who was selected this spring as People for the Ethical Treatment of Animals’ ”sexiest vegan.“ ”This is definitely permanent for me, especially with meat,“ she said. ”I’m completely disgusted by it. I don‘t want to be around it. I see it and I hate it.
”Having the community is helpful,“ she said. Pittsburgh has an active vegan community, with a series of events this month revealing its zeal in promoting the lifestyle.
On Wednesday, Vegetarian Summerfest gets underway in Johnstown with a long lineup of the nation’s most notable vegans and vegetarians, including Dr. Greger and Mr. Cohan of Jewish Vegetarians.
Later this month, on July 19, Pittsburgh Vegan Festival will be held at the Allegheny Unitarian Universalist Church, 416 W. North Ave., North Side.
Vegan Pittsburgh, with a website, VeganPittsburgh.org, and Facebook page, has a campaign underway to encourage restaurants to offer clearly labeled vegan options and earn the organization‘s encircled-V decal for the front window or door. The group features different vegan-friendly restaurants, with members posting photos of their meals on the Facebook page. The photos prove that the vegan diet is not just salads and carrot sticks.
Niki Penberg of Vegan Pittsburgh is a 36-year-old Lawrenceville resident who competes in distance and endurance races. She said 46 Pittsburgh-area restaurants have earned the Vegan Pittsburgh logo, with the group meeting with restaurant owners and managers to increase that number. It also encourages vegans to patronize the restaurants with vegan fare, often including Indian, Chinese, Thai, Middle Eastern and Mexican restaurants. Lawrenceville and the South Side are vegan strongholds, she said.
Whether animal rights, the environment or health concerns served as inspiration, all vegans or wannabes are welcome.
“We’re all in the same room but we entered through different doors,” Ms. Penberg said, “Pittsburgh now is a great place to be a vegan. We want to spread the vegan joy.”
Inspired by the healing powers of a plant-based diet, Rebecca Gilbert, 42, of Shadyside, began her popular website, YummyPlants.com, which now serves as ”a portal into the vegan lifestyle.“ She also has a large Facebook and Twitter following.
On July 12, Vegan Pittsburgh will sponsor a free event from 4 to 7 p.m. at the Stephen Foster Community Center in Lawrenceville to launch her book, ”It‘s Easy to Start Eating Vegan.” Local restaurants will provide vegan food.
Ms. Gilbert’s own health success with the lifestyle explains her advocacy.
At age 15, the native of Chippewa, Beaver County, became so interested in competitive ice skating that she moved to Lake Placid, N.Y., to train at the Olympic Training Center. The excellent jumper, capable of doing triple jumps, never quite reached Olympic caliber but continued skating throughout high school and during her years at the University of Pennsylvania. After graduation, she received an invitation to participate in Disney‘s “Beauty and the Beast” European tour.
But pain in her knee forced her to skip the tour. She underwent cortisone treatments, electrical stimulation and surgery to release pressure against her kneecap. No longer able to skate, she returned to school, earned an MBA degree and went to work. But in time she came across a Scandinavian study that concluded that a vegan diet had succeeded in eliminating knee pain.
“The very next day I went vegan,” Ms. Gilbert said. “Five weeks later, I was back on the ice. It’s a real testament of how veganism helped to heal me.”
