Fructose Inhibits Brain Response.

Fructose and Glucose Elicit Opposite Responses in the Human Brain.

I’ve had an ongoing disagreement with the National Corn Growers Association for years as to whether high fructose corn syrup reacts differently in the human brain and body than glucose.  They’ve written letters to the editor of papers I write for and sent me e-mails trying to convince me, and readers of my columns, that my anecdotal information and scientific sources are incorrect.  

Recently, Oregon Health Services University (OHSU.edu) published a paper stating, “This study provides evidence in humans that fructose and glucose elicit opposite responses in the brain.  It supports the animal research that shows similar findings and links fructose with obesity.”” Jonathan Purnell, M.D.

The report went on to say that fructose inhibits brain activity and many experts agree the increase in fructose and high fructose sweeteners in the American diet “directly correlates to the nation’s growing obesity epidemic.” 

Using the latest functional MRI techniques allowed the researchers to watch different parts of the brain in real time and compare the brain’s reaction to foods.  Fructose, glucose and a saline solution were tested on nine normal weight humans.  When the MRI test groups were compared, “scientists observed significant differences.”  “What we found in this case is that the brain’s response to fructose is very different than the response to glucose, which means it (glucose) is less likely to promote weight gain.”

The report went on to say that responses in one area of the brain that’s involved in regulating food intake, the hypothalamus, showed no difference between fructose and glucose.  But, opposite responses were shown in the cortical area of the brain between fructose and glucose.  This is a significant finding since the areas affected are important in determining how we react to tastes, smells and even pictures of food.  The response to fructose could be termed “eat more.”  Other sweeteners, like those found in sugar free diet sodas, appear to work on the same areas of the brain and in the same negative way.

“For consumers, our findings support current recommendations that people be conscious of sweeteners added to their drinks and meals and not overindulge in high-fructose processed foods.”

Jonathan Purnell M.D. is an associate professor of medicine, endocrinology, diabetes and clinical nutrition in the OHSU School of Medicine.

I have to assume the National Corn Growers knew this to be true some time ago, but wouldn’t admit it.  Why else would they petition the FDA in hopes of being able to change the name from high fructose corn syrup to “corn sugar.”  Be aware, if they get the go ahead to change the name, it will still be the same old stuff.   

Larry Miller: I was born in Los Angeles in 1940. My father was a fighter pilot instructor during WWll and we moved from coast to coast, maybe that’s where I got the nomad in my blood. After graduating from high school in 1958 I joined the Marines. That lifestyle wasn’t for me and upon my discharge I went on with my life, and have never looked back. I worked briefly for a Caterpillar dealer in Riverside, CA before moving back to N. California where I was a welder and truck driver for a chemical company. Truck driving wasn’t my calling anymore than being in the Marines, and I went back to work for another Caterpillar dealer steam cleaning dirty tractor parts and welding. They sent me to schools, lots and lots of schools. I spent as much time going to trade schools as I did at work. I went from cleaning parts to apprentice field mechanic, to mechanic to the parts department to satellite store manager in less than two years. They wanted me to move to Sacramento and be a salesman: I moved to Oregon to learn to commune with nature. I went to work for another heavy equipment dealer and was later contacted by the World’s largest Lorraine Crane dealer and offered the position of purchasing agent and general parts manager. In 1967 I was offered a line of automotive parts and supplies and went into business for myself. My business revolved around eleven race cars that we maintained for others, driving race cars professionally and maintaining high end sports cars. I was a championship and regional champion driver. My business was the largest import parts and service, non dealer, in the state until I sold it in 1979. We went sailing in 79, first to Mexico and then Hawaii. I was an award winning Trans-Pacific sailor and sailor of the year, Hawaii, Island of Kauai. An opportunity presented itself in Hawaii during 1981 and I was back in business, importing Japanese auto body and hard parts. I also felt the pull to write and began freelancing for magazines and newspapers in 1982. My main focus in my articles is, and always has been, health, wellness and fitness. Most of us have heard the saying, “Time is all we have.” I disagree. Our health is all we have, because without our health, we have no time. I was a US Olympic team hopeful in racewalking and held all the records for the state of Hawaii. As a sponsored athlete in my forties, I finished first in nine marathons in a row in my division, qualified for the Ironman® and was the state USCF cycling champion five times in Hawaii and Oregon. Celinda and I were married in 1988 after a three year engagement. We sold our businesses and organic farm and sailed back to Oregon. After our sailboat boat was sold, we moved to Joseph, Oregon, two miles from the trailhead into the Eagle Cap Wilderness. We were caregivers for my mother the last ten years she was alive. We moved to New Mexico in 1995 because it was too cold for my mom in Oregon during the winters. Celinda designed, and I engineered and built our strawbale house. I began writing the weekly health column for a local newspaper in 1996, and still do. In 2000, I took the summer off to do a four month, 4000 mile, hike, bike and kayak odyssey. I’d been writing health, fitness and sports articles since 1982 and the journey produced a full-length, nonfiction, first person adventure book, Yol Bolsun, May There Be A Road, which can be bought from Amazon.com and others over the Internet. The summer of 2001 was spent hiking. kayaking, fishing and exploring the southwest. In 2002 Celinda and I spent the summer in Canada learning the hospitality business at a resort in preparation for doing promotion for the resort in the US. Most of 2003 was spent reestablishing the trees and landscape that had died during the stay in Canada. We had a house sitter and the house sitter had an ex-husband, and that’s a long story. In July of 2004 I did a solo kayak trip on the Snake River, taking pictures, writing articles and pencil sketching the journey. I hope to do another kayak adventure on the Snake River during the summer of 2008, on the section I missed in 2000 and 2004. In 2005, I returned to Canada to the resort where we’d spent 2002. I was supposed to be there for the month of June. I’d contacted people I’d met in 2002 and they came back to Canada to fish, hike and spend time at the resort, Echo Valley Ranch and Spa, while I was there. My one month became five and then it was off to Spain to do the El Camino de Santiago as a travel companion with one of the guests who’d returned to Canada in June. During the summer of 2006 a friend from Ireland, who I’d met in Spain the year before, came to visit in NM and we fished, hiked and explored the White Mountains of AZ. He’d never slept out in the wild in a tent before, and it was quite an experience, for both of us. My newspaper articles were put on the Internet beginning in 2002. I was asked to give public speaking engagements, photo and video presentations, on various subjects for the library in Deming, NM and continue to do so. In 2006 I videoed and produced a DVD for the Smithsonian Institute’s travel exhibit “Between Fences.” NMFILMS had a conference by invitation only, which I attended. While attending the conference, I realized that film making wasn’t what I wanted to do but I still wanted to use my sixteen years of experience and enjoyment of videoing and photography. During the winter of 2005, I discovered that no one on record had ever run from the Arizona border to the Texas border, a distance of 165 miles. During the spring and summer of 2006 I trained for the run and the run was completed in October, 2006. In late 2005, I began building and maintaining websites incorporating all the things I enjoyed about video, photography, travel and the out of doors. 2007 has been a summer of upgrading the home and property which resulted in a downgrading of my enthusiasm for being located in one place. If we don’t like what’s happening in our life, we need to change what we’re doing. Celinda and I are ready to pull up roots and move on. I guess I’ve come full circle. I’m ready to revert back to my childhood, and a nomadic lifestyle.
