Formula One racing champion Lewis Hamilton has joined the growing number of hard-driving athletes who use plant power to fuel peak performance. He’s been on a plant-based diet a month now, and in a new Instagram post he says he feels the best he ever has!

Hamilton quoteHe joins the ranks of tennis stars Serena and Venus Williams and Novak Djokovic; the NBA’s Damian Lillard, Wilson Chandler, and Jahlil Okafor; the NFL’s David Johnson and  Cardale Jones; and dozens of other elite athletes whose plant-based diets put them on the inside track to success.

Across the spectrum of sports, athletes have attributed a plant-based diet to improved endurance, strength, recovery, and concentration.

Williams says a vegan diet actually helped her get back in the game after autoimmune disease halted her career in 2011. Djokovic says a vegan diet made him more aware of his body on the court and more alert.

The science backs them up. A plant-based diet, which emphasizes whole grains, fruits, vegetables, and legumes, provides healthy complex carbohydrate for energy, balanced with the protein and fat the body needs for training sessions and competition, but without the blood-sludging saturated fat that predominates in cheese and meat. A vegan athlete will get all the vitamins and minerals he or she needs to best perform, recover, and perform again.

Off the race course, a vegan diet will also help Hamilton’s race to fight climate change and his family history of heart disease and cancer.


Cycling Across China with Vegan Message

Cycling across china with a vegan message
Cyclists led by the Physicians Committee’s Jia Xu, Ph.D., are inspiring people across China to learn about the health benefits of a vegan diet. Dr. Xu, who frequently lectures about plant-based diets in China and manages the Physicians Committee’s Mandarin-language 21-Day Kickstart, is leading a team of cyclists from Shanghai to Lhasa—about 2,500 miles.

While in Shanghai, Dr. Xu also filmed videos that Food for Life instructor Kimberly Ashton will use in her recently launched diabetes and cancer classes. She says that students are impressed and surprised with the health power of plant-based foods and that more and more people want to learn how to prepare healthful plant-based meals.

Here are photos from Dr. Xu’s journey and Ashton’s Food for Life class:

Pretty in Pink: As Seen on WJLA-TV (ABC)’s Good Morning Washington

Guest post by Lee Crosby, R.D.

In 2010, my doctor found some suspicious spots in my left breast. A biopsy showed they weren’t cancer, but that I had a higher risk for cancer down the road. My doctor also found a “thickened” area in my right breast she wanted to keep an eye on.

I was only 30 years old, so that got my attention! I was determined to do everything I could to reduce my future risk. While no eating pattern gives 100 percent protection against cancer, I was impressed by research showing that plant-based diets cut cancer risk. I also took up exercise. And all was well for many months.

Then I fell off the wagon. It’s a long story, but I stopped exercising and went back to eating meat. And that "thickened" area they’d been following—which had been stable when I was plant-based. It doubled in size in just four months of eating meat.

Within a week, I was under the knife having a lumpectomy. The results came back “atypical,” or one step before cancer.

Needless to say, I got right back to eating a plant-based diet! I even went back to school to become a registered dietitian, having personally experienced the power of nutrition. It’s been four years since my last surgery, and so far all reports are clear.

While having breast issues was stressful, I’m grateful for the knowledge I’ve gained about reducing breast cancer risk, and I try to pass it along as useful tips for my family, friends, and patients. While research is still developing in the field of diet and disease prevention, this much I know for sure: Wearing a pink ribbon to raise awareness of breast cancer is good, but doing what we can to reduce our risk of getting the disease or having a recurrence is even better.

In fact, The World Health organization finds a healthful diet and lifestyle can help reduce overall cancer risk by 30 percent. Of course, most forms of cancer still result from random mutations—no one is ever to blame for cancer! But thankfully, there are plenty of steps we can take to fight back.

Here are a few ways to start:

  1. Eat Pink. (And orange and red and green and purple!) By eating most colors of the nutrition rainbow each day, you’ll consume a variety of phytochemicals, like sulforaphane, allyl sulfides, and anthocyanins, which team up to produce healthy genetic material, reduce cell division, and destroy free radicals. While multivitamins and supplements provide a safeguard for nutrients we can easily fall short on, like vitamin D, they don’t provide our bodies with the full spectrum of anti-cancer compounds we can easily get from colorful plant foods.

Rx: Aim to eat seven colors of the nutrition rainbow each day. To get started, try incorporating a few different colors of plant-based foods—like leafy greens, carrots, onions, berries, and beans—into your daily meals. Then experiment with a new vegetable, like purple cauliflower, butternut squash, or Daikon radish, each week.

  1. Fill Up with Fiber. Fiber—also known as plant roughage—helps support a healthy gut and removes carcinogens, or cancer-forming compounds, from the body. As a bonus, fiber also helps keep us "regular."

    Most Americans get about 16 grams of daily fiber, but we should aim for 35 to 40 grams.

    Beans, peas, and lentils are fiber superstars! However, fruits, vegetables, and whole grains are also great sources of fiber.

Rx: Consume at least 35 to 40 grams of fiber a day. Try experimenting with apples, lentils, and soybeans (edamame), which double as quick snacks and add-ons to salads and DIY-meals.

  1. Pack In Produce. Try to eat two pounds of fresh or frozen produce a day. In fact, some days I aim to eat two pounds of vegetables a day, with fruit on top of that. By shooting for two pounds of vegetables, I know my body is getting plenty of protective phytonutrients without a lot of calories. And I’m never hungry!

    In fact, the meal we showcase on WJLA’s Good Morning Washington has three or four pounds of produce but less than 1,600 calories. It also has 55 grams of protein, 72 grams of fiber, four times the recommended daily intake (RDI) of vitamins A, C, and K, and twice the RDI of folate, magnesium, and selenium. Studies find women with the highest intake of carotenoids—think orange and green vegetables—are less likely to develop breast cancer.

Rx: Aim to eat two pounds of produce a day, which is the equivalent to six to eight cups of fruits and vegetables. One easy way to start is by adding leafy greens and vegetables to every meal—even breakfast!

So in addition to donning a pink ribbon this month, try these take-home tips:

  • Aim to eat seven colors of the nutrition rainbow each day.
  • Fill up with 40 grams of daily fiber.
  • Eat two pounds of produce most days of the week.

Tom Petty's Cardiac Arrest a Reminder to Check Heart Health

Tom Petty's Cardiac Arrest a reminder to check heart health

The rock star Tom Petty—whose more than 40-year career with his band The Heartbreakers included hits like The Waiting and Into the Great Wide Open—died from cardiac arrest yesterday at the age of 66. I hope that his cardiac arrest will serve as a reminder of the need for action against heart disease—the No. 1 killer in America—and that his millions of Heartbreakers fans will indeed take the message to heart.

Research shows that the most effective steps for fighting heart disease include managing blood pressure, controlling cholesterol, eating better, and losing weight. These steps can all be achieved through a healthy plant-based diet. Meat, dairy products, eggs, and fatty snack foods harbor the saturated fats and trans fats that push cholesterol into the blood stream. Avoiding animal products and other fatty foods allows arteries to clean themselves out.

How Egg-Industry-Funded Studies Harm Public Health

How egg industry funded studies harm public health

How did a recent research review dupe Americans into believing that cholesterol isn’t a health concern? Ten of the 12 included studies were funded by the egg industry. Take a look:


The systematic review was limited to studies published after 2003, when nearly all cholesterol studies were funded by the egg industry, in contrast to earlier years when governmental bodies played a bigger role in cholesterol research. Of 12 included studies, 10 were funded by the egg industry seeking to make cholesterol look innocuous.

Want to learn more about how faulty nutrition studies harm public health? Read the Misuse of Meta-analysis in Nutrition Research, my new JAMA commentary with Walter C. Willett, M.D., Dr.P.H., and Eric L. Ding, Sc.D., from the Harvard T.H. Chan School of Public Health.
