Junk Food Diet Speeds Development Of Pancreatic Cancer

Junk Food Diet Speeds Development Of Pancreatic Cancer

A study has shown that a diet high in fat and calories can hasten the development of pancreatic cancer in humans.

In a presentation to the American Association for Cancer Research's Pancreatic Cancer: Progress and Challenges conference, researchers said their results showed a clear link between diet and pancreatic activity.

"Our results showed that in mice, a diet high in fat and calories led to obesity and metabolic disturbances such as insulin resistance that are seen in obese humans," said Guido Eibl from the David Geffen School of Medicine at the University of California, according to a statement.

diet

"It also greatly enhanced pancreatic inflammation and pancreatic cancer development."

Human epidemiological studies have linked high fat intake and obesity to an increased risk of pancreatic cancer, but the mechanism driving this association has not been understood.

To understand the link, Eibl and his colleagues first tested the hypothesis that diet is linked to cancer. They fed a corn oil-based diet that had a high content of fat and calories to mice with a genetic mutation that caused them to develop pancreatic precancer. The same gene, KRAS, is mutated in the majority of human pancreatic cancers.

The results showed that 90% of the mice fed the special diet became obese, and all of these mice developed insulin resistance and inflammation in the pancreas. Both of these conditions can stimulate the growth of precancerous cells and cancer. These mice also developed significantly more advanced precancerous lesions than did mice fed a normal diet.

"This suggests that the high-fat, high-calorie diet accelerated pancreatic cancer development," said Eibl.

"A KRAS mutation in the pancreas might not be sufficient to cause an individual to develop pancreatic cancer. It likely needs something in addition a secondary hit. Our study showed that a high-fat, high-calorie diet could provide an environmental secondary hit and trigger cancer development."

The researchers are now defining the role that inflammation produced by obesity plays in development of the cancer, and if agents such as antidiabetic drugs or fish oil can halt this disease process.

Anna Leahy: 5 Myths That Stop Us From Achieving Our Goals

Anna Leahy: 5 Myths That Stop Us From Achieving Our Goals

1. You can't control inspiration or insight; it just happens.

If you're still clinging to the notion that good ideas pop randomly into a person's head, then you're not reading the books on the New York Times bestseller list. From Malcolm Gladwell to Jonah Lehrer, popular authors have spent the last 10 years interpreting the scientific studies to change the way we understand problem solving and creativity.

In her book The Midnight Disease: The Drive to Write, Writer's Block, and the Creative Brain, which is part memoir and part science, neurologist Alice Flaherty argues, "[W]riting regularly, inspiration or no, is not a bad way to eventually get into an inspired mood; the plane has to bump along the runway a while before it finally takes off."

Hard work, along with an openness to ideas, can generate inspiration because the creative process occurs in stages: defining the problem, learning as much about it as possible, reaching an impasse, gaining insight, and testing that insight. Inspiration may feel like magic, but it's part of a progression. Don't sit around waiting for your great idea.

It turns out that being in a good mood cultivates insight, too. Flaherty (and recently Lehrer in his book Imagine: How Creativity Works) suggests, "Joy can even give a sense of being inspired when no real inspiration exists."

2. If you want something done right, do it (by) yourself.

2012-06-14-DeskClutter.jpg Individualism is American. We're do-it-yourselfers. We resist working collaboratively for fear that we will lose track of what's mine or not get appropriate credit.

When it comes to ideas that change the course of things to come, though, "a group is not just a collection of individual talents." In Imagine, Lehrer goes on to assert, "Instead, it is a chance for those talents to exceed themselves, to produce something greater than anyone [or any one individual] thought possible." After all, "If we're not here to make one another better, then why are we here?" In other words, stop being selfish -- or rather, collaboration is the new selfish.

Even those of us working in isolation to a great extent benefit from being part of something larger. In The Creating Brain, psychiatrist and Renaissance literature scholar Nancy Andreasen recognizes "cradles of creativity" that "produce a cultural environment that nurtures creativity." One of the characteristics of such an environment is "a critical mass of creative people." It turns out that "creative people are likely to be more productive and more original if surrounded by other creative people."

You shouldn't hang out only with folks just like you, but brushing up against others who have big goals is good for everybody involved. And according to Andreasen, some healthy competition with other ambitious people helps too.

3. Mistakes are bad.

We tend to think mistakes get in the way of progress or, worse, mean failure. With small tasks, that's likely. When you leave a Kleenex in the laundry, you're going to waste time and energy. A typo in an application letter can cost you a job.

But when it comes to thinking big and achieving something over time, error is an important part of the process. As Steven Johnson notes in his book Where Good Ideas Come From, "Error often creates a path that leads you out of comfortable assumptions. [...] Being right keeps you in place. Being wrong forces you to explore." As writer Samuel Beckett said, "Fail better." Or as today's engineers say, Fail faster. Author Neil Gaiman came up with the character name (and book and film title) Coraline when he mistyped his friend Caroline's name in a letter. Some mistakes are opportunities in disguise.

Johnson (and Lehrer, too) points to studies by psychologist Charlan Nemeth that indicate dissent, like error, "can dramatically expand creative potential." If you never risk making a mistake or having anyone contradict you, you're probably stuck.

4. The more you have to do, the more plans you need.

2012-06-14-KnoxCollegeArtStudio.jpg To achieve something big or long-term, you need a step-by-step plan to which you hold yourself accountable. That works.

But that works for one big goal, not for six. Most of us are multi-taskers, juggling multiple projects and ideas at once. A recent article by Art Markman in Psychology Today reveals:

"[W]hen there was only one goal, people were more committed to that goal and thought it would be less difficult to achieve the goal when they formed an implementation intention than when they did not. When there were six goals, though, the implementation intention made people feel that satisfying the goals would be difficult to achieve, and so the plans actually decreased people's commitment to the goals."

In other words, a step-by-step game plan works great because it keeps you on track. But when you have multiple plans for different tasks (or too many disparate tasks in a plan), each one tells you when you're falling behind.

The answer Markman (whose blogs also appear on The Huffington Post) suggests is to "try to scale back your expectations." Another way to solve the multitasking problem is to prioritize. That's not to say you should focus on one thing to the exclusion of all else, for you might then miss an insight in your peripheral view. Still, make one or two big things priorities, and stop worrying about dust bunnies.

5. You have to be the best at what you're doing.

In order to succeed, you have to better than everybody else. Wrong.

In reality, to succeed, you must stick with your big goals, outlasting others. Psychologist Angela Duckworth calls this grit and claims that it's one of the qualities necessary to unlock talent. In an article in The Boston Globe, Lehrer suggests that smart people may be less likely to work hard and, therefore, may not take advantage of their talent. And in his book Outliers, Malcolm Gladwell popularizes studies by psychologist K. Anders Ericsson and others that show 10,000 hours of practice is necessary to achieve expertise in something. That's sticking with something for about 20 hours every week for almost 10 years.

Neil Gaiman put this idea another way in his commencement speech at the University of the Arts:

"People will tolerate how unpleasant you are if your work is good and you deliver it on time. People will forgive the lateness of your work if it's good and they like you. And you don't have to be as good as everyone else if you're on time and it's always a pleasure to hear from you."

Even if you're the best, achieving goals depends on other qualities, too.

Happy Father's Day! A Celebration Of Your Fit Dads

Happy Father's Day! A Celebration Of Your Fit Dads
  • Rene Arguello

    Physical fitness has always been of great importance to my dad and has influenced me in so many ways. While in the Navy, my dad was on the U.S Navy fast pitch softball team, and even after he married my mom he still continued to play fast pitch softball in different city leagues. <br><br> As a boy I was amazed watching him at the plate batting and scoring runs. My dad is in his late 70s and he still continues to amaze and influence me. He had a triple bypass about eight months ago and after a couple of months of recovery he still leads a active lifestyle. He and my mom attend the gym at least three or four times a week. I figure if he can do that so can I. I am in my late 40s and I also find myself at the gym at least three or four times a week now. Sometimes I find myself on the treadmill right next to him. What a great influence I have!

  • Molly Antos

    My dad always makes me work out with him on family vacations. I like to run, but he is a huge stair-stepper fanatic. My dad also helped me stay on track so I was fit for my wedding.

  • Jenna Autuori, Fitness Editor, Mind Body + Spirit

    My dad was such a <em>huge</em> influence on my athleticism growing up! I always wanted to do whatever my older brother was doing. When he took up martial arts and I anxiously watched his every practice, my dad encouraged me to sign up too. I was the only girl in this martial arts studio for almost 10 years and I competed with the guys and won trophies at regional competitions. Without my dad telling me I'm "tough" and I can do anything I put my mind to, I wouldn't have thought this sport would be for me -- but it was all I ate, slept and dreamt about as a kid. My dad tried to get me to see the upside of going to a college like West Point where I could be a leader and be on sporting teams, and hopefully take my "fighting" skills to boxing. However, I never did do this. <br><br> As I got older and entered junior high and high school, I also played lacrosse and ran cross country as well, and my dad never missed a game. I practiced, played games and competed in everything I did for me, but I also always knew that this was the bond that my dad and I shared, and that seeing me out there probably made him so proud. I looked forward to showing him how much I'd improved every week at practice and when I scored goals in a lacrosse game, he was the first person I high-fived. My entire athletic "career" and healthy living is owed to my dad. <br><br> Besides playing sports, my dad was an avid exerciser and when he got home from work and hit our home mini-gym every day, I would tag along too and he would teach me how to use dumbbells and do whatever else he was doing. I was like the fly that never went away when my dad hit the gym. <br><br> When I entered college (Fordham University) I guess you could say my athleticism sort of slowed down, as it does for most college students. I didn't want to play on a university team and preferred for once to not live by a strict training schedule. After a whirlwind of four years (I still hit the gym weekly) and upon moving into the city on my own, I randomly signed up for an Olympic distance triathlon because I missed training for something and that "team" aspect I hadn't had since high school. My dad was the first person I called and told the news. Even though his response was, "Jenna you hate open water and you're petrified of the thought of sharks," we laughed together when I told him I'd wing it and just push that thought out of my mind on race day. <br><br> He was my biggest supporter as I took on this new -- and some thought crazy -- goal. This was about four years ago when triathlon training wasn't as "common" as it is now for the everyday gym rat, so there weren't so many girls like me jumping into such a crazy sport. But my dad was my biggest fan -- he bought me my first racing bike and on race day, hugging him before I hit the Hudson water for my swim was all the encouragement I needed. I've since done three triathlons and I'm doing my fourth next month in the Hudson again. <br><br> My dad has been there for every race, competition and sport I tried and I really think I owe my entire love for being active to him. I still think about his crazy dream of sending me to West Point to get into boxing now that boxing for females takes the spotlight for the first time during this Summer Olympics. I remember when I was traveling a lot for karate as a kid and he said if I kept this up, as the only girl in the sport and usually the only girl in the regional competitions, that I could maybe one day box/fight in the Olympics. I said, "Dad, you're crazy." But now that I see Marlen Esparza off to the Olympics, I think that maybe that could have been me. My dad thought so at least! <br><br> As a fitness editor I research, try and write about all the new workouts and give readers advice and tips for staying fit, but my dad has been my biggest inspiration and helped shape me to be who I am today. Maybe for him -- and myself -- I'll get back into karate too. I owe everything to my dad and I am so proud he taught me and encouraged me to be a strong athlete.

  • Desiree Stojino

    My Dad didn't allow us to eat candies or drink sodas when we were kids. Because of that my siblings and I all have great sets of teeth.

  • Jennifer Strober

    As a child I remember how important health was to my father, Robert (Butch) Scully. He returned from the Vietnam War, serving two years, carrying two Purple Hearts and several scars. Not just physical but emotional. <br><br> I was born a few years later and became his hiking, fishing, swimming, football, biking, camping, boating and you name it sports buddy. I was not only his "princess," I was his little athlete. For my entire life -- 40 years -- he has continued a healthy living lifestyle. A vegetarian, gym-going active man, he is now 63. Dad has not only taught me that health and exercise are good for your body, but he also instilled a "Nobody is Perfect" attitude and the understanding that "We can't change the past. We can only remain strong and move forward." I carry these thoughts with me every day as I raise my two young boys and train my clients. <br><br> I am currently a fitness instructor/wellness coach seeking a certification to teach yoga. I definitely feel his influence helped move me in this direction and I'm very grateful and proud he is my father. <br><br> On a side note, a few years ago, my father was bit by something while gardening in his backyard in NJ. The doctors are still not sure what caused it, but he ended up going into toxic shock. It was touch and go, for what seemed the longest week of my life, as I watched one kidney failing and his heart needing to be shocked. The doctors all told us that if he hadn't been in the health he was at the time he got sick, he probably wouldn't have been able to fight off the infection. <br><br> After that experience, I began reading more on nutrition and holistic health. I now coach and advise in those fields, as well as practice them in my home with my children. Fortunately, he made a full recovery and continues to live a happy and healthy life closing in on retirement.

  • Sabrina Greenwood-Briggs

    In grammar school, my dad got up at 5:00 a.m. every day with me to help me train for my cross country races.

  • Yvonne Barajas

    The breeze of the summer days never felt as wonderful as they did at the park during the good old days of my youth. It feels as though it happened decades ago, yet I can vividly sense it all as though I were right there, right now. It was just Daddy and me, at the park walking around, listening to his stories as I searched for the rabbits and squirrels. <br><br> Everything amazed me at that age. I was around 10 years old or so, and I thought my dad was the handsomest man alive. I did not ask for much, just to spend some time with him, and to hear his stories and the answers to my many questions. <br><br> He would randomly chase me and I would try to sprint as fast as I could to try to beat him. We would walk by the bike route and let the sun be our clock -- when the sunset became vivid, it was our cue to head home. As the years went by, my dad found a second job to make ends meet and the time we spend together became limited. But my dad is a truly wonderful man who works in the rain, even when he has a migraine. <br><br> The time he has free though, he uses to spend time with us -- my mom, my sister and me. I still remember looking for him out the window, asking my mom when he would be back from work, tears rolling down my face. I still run to him when he gets home from work and I do not sleep until he arrives safe and sound. I would give anything to have my childhood years back because he made those the most wonderful years of my life.

  • Jacqueline Howard, Associate Science Editor, Huffington Post

    When I ran track in high school he would train with me sometimes, even after my team practiced, because he always encouraged me "to go beyond what's expected of you!"

  • Brooke Hugron, @brookiehugs

    I've run three half marathons with my dad and even crossed the finish line together hand-in-hand on one.

  • Maria Mooney, @happyhealing44

    My dad was a marathon runner and still runs daily at 60 years old. No surprise I love the sport!

  • Henrique Autran, Herbalife International

    My father started running when he was 30. He quit smoking and began to invest himself in a healthy lifestyle. I was two years old when he started. When I was 10, I began to run with him and practice karate. <br><br> He has always invested in our (my sister and brother and me) so we can have a healthy lifestyle. Today, he is 72 (and still running, although not as much as before) and I am 37. I'm practicing running and lifting weights. It is a great honor to be my father's son and share with you our love for a healthy lifestyle!

  • Heather, @followheatherj

    My Dad raised me since I was 2 1/2 and started off our relationship with a promise. During the wedding to my Mom he presented her with a ring but he also presented me with my own ring. He gave me a small gold band which I'm told was his promise to me that he would be there for me and be the best Dad he could be to me. (Who does that?!) Little did I know that this man would be my biggest supporter in life. <br><br> I could not have been blessed with a better person to call Dad. Throughout my life he has always been there for my mom, sister and I. He would give us sound advice, surprise us with flowers every now and then, write us long letters of wisdom/love on our birthdays and would always live by example and teach us how a man should act. He also took me to my first concert when all of my friends weren't able to go. His character goes well beyond my family though ... everyone who knows him loves him. He is the kind of person you always want around. He's funny, witty, honest, trustworthy and charismatic. He even brings his dry cleaning lady little loving gifts just to show her she is appreciated. <br><br> While he has not had an easy road in the healthy living department due to heart issues (he's a meat eating midwest boy after all), he is doing well and my family is always finding funny ways of sneaking spinach into his meals. I trust my Dad to always lead me in the right direction and I always strive to make him proud. He and my Mom have the best relationship I've ever seen and I hope to marry a man like him.
