Deadline Detroit | Dr. Joel Kahn: The benefits of a vegan diet, even for just a week or a month, are real and dramatic


Twice a month, health columns are written by a practicing cardiologist, clinical professor at Wayne State University School of Medicine and founder of the Kahn Center for Cardiac Longevity at Bingham Farms. He is an author and has appeared on national television, including “Dr. Oz” and “The Doctors Show.”

More and more people are opting for plant-based meals. Steakhouses have vegan options. Airports offer kale salads. Grocers are devoting more shelf space to new meatless products.

I have seen dramatic health improvements when patients adopt a vegan diet. Some people jump into the pool and others dip their toes in for quite a while before getting in.

What if everyone skipped all animal products and ate only plant-based flours for just one day? While it can be difficult to gauge the health impact of just one day of eating plant-based foods, just one week of a vegan diet can lead to big changes in your appearance and well-being.

Additionally, the environmental impact would include reduced water, fuel and land use, fewer crops for livestock, fewer antibiotics needed for animals, reduced soil erosion, animal excrement and ammonia emissions.

Another method of evaluating entry into a vegan diet is to use a vegan calculator that measures the impact of adopting a vegan diet for one month. After one month, one individual has reduced his projected environmental impact by averting the death of 33 animals, the use of 33,000 gallons of water for the production of animal feed, the destruction of 900 square feet of forest, the creation an additional 600 pounds of carbon dioxide and feeding 1,200 pounds of grain to animals that could have helped starving people around the world.

Of course, the daily impact of a vegan diet could be estimated by dividing these staggering numbers by 30.

Movements like Meatless Monday that promote one day a week to avoid animal products have grown rapidly. Founded in 2003, in association with the Johns Hopkins School of Public Health, the organization has grown to 44 countries and is expanding. Your decision to go a day without eggs, dairy products and meat of all kinds is a positive step forward for your health, an awareness of the suffering of farm animals and a relief for our world suffering from the burden of feeding more than 7 billion people.

The impact of just one day on a healthy vegan diet can inspire you to fully embrace the diet I followed for 45 years and taught heart patients for over 30 years. You will never regret it, even if you only do it for one day.
