Star Metro - Mike Tyson, healthy eating advocate for Trump administration

The former heavyweight champ has lent his face to an ad campaign with the slogan "Eat Real Food," as opposed to ultra-processed products that are popular in America. An ad generated by the campaign aired Sunday during the Super Bowl.

"This is the biggest fight of my life," Tyson said Wednesday at an event with US Health Secretary Robert F. Kennedy Jr.

Tyson is a poster child for public rehabilitation from disgrace, as his boxing prowess was marred by a rape conviction and prison stint, as well as a fight in which he bit off part of his opponent's ear.

In the new black and white commercial, Tyson, 59, recalls that his sister Denise suffered from obesity and died of a heart attack at age 25.

He recounts a tough childhood battling his own weight issues, eating junk food all the time and weighing as much as 345 pounds (156 kilograms).

"I had so much self-hate," Tyson says in the ad. "I just wanted to kill myself."

"Where I come from is Brownsville, Brooklyn. It's the most violent, poverty-struck neighborhood in the city of New York. And ultra-processed food was just the norm," Tyson said at the event with Kennedy, whose slogan is "Make America Healthy Again."

Americans consume a diet heavy in calories that come from ultra-processed foods and are among the world's worst offenders in this category, according to government figures.

Eating food rich in sugar, fat, salt and preservatives is associated with a higher risk of obesity, diabetes and cardiovascular problems.

Among a blizzard of changes to US health policy including de-emphasizing vaccines, Kennedy last month flipped the American food pyramid upside down to encourage people to eat meat and whole-milk dairy products.

Fiber-rich whole grains like oats are now at the bottom of the chart.

Critics have raised concerns that this change might be a result of lobbying from the agriculture sector.

Tyson became the undisputed heavyweight boxing champion in the 1980s, terrifying his opponents with his fury in the ring and a phenomenal punching power.

But he spent three years in jail beginning in 1992 after being found guilty of raping model Desiree Washington, who was 18 at the time.

In a notorious 1996 matchup, Tyson bit off a piece of his opponent Evander Holyfield's ear.
