Reportedly, the 100 year old woman - Helen Diekman, who passed away last week, had talked humorously that consuming hot dogs from Portillo's was her secret to long life. The Daily Herald reported that Diekman, the hospital volunteer from Illinois who was considered a regular customer at Portillo's ordered the same meal three times a week - a hot dog with everything on it except hot peppers, a Diet Coke and fries.

But the hospital volunteer was not the only person who celebrated her 100th birthday who admitted her unconventional way of eating. The world's verified oldest living person - Jeralean Talley, who passed away on July 2015 at the age of 116, confessed her fondness for chicken nuggets from the world's largest chain of hamburger fast food restaurants - McDonald's and chili from the American international fast food restaurant - Wendy's.

Jeralean Talley also consumed honey buns, potato salad and likes to stay up until midnight.

Then there's the 110-year-old Agnes Fenton from New Jersey, who according to The Record found  pleasure with having a shot of scotch and three beers every day for almost 70 years - as stated by some media outlets.

There's also, the world's oldest living person - Susannah Mushatt Jones, who as Page Six reports consumes meat regularly, as well as "bacon all day long."

However, Nieca Goldberg, MD, Clinical Associate Professor for the Department of Medicine and medical director at NYU's Langone's Joan H. Tisch Center for Women's Health stated this to Yahoo Health, "Well, it's not just about what a person eats, it's also about their genes." Goldberg added, "These women have already showcased that they have some kind of longevity gene."

Dr. Nieca Goldberg stated that aside from genetics and diet, there are a few other vital factors that may contribute of hitting up an age up to a triple digit. Dr. Nieca Goldberg claimed that, "Living a happy life, being a positive thinker as disagreeing with a negative thinker and being physically active, which has been documented by medical research."
