The food additive monosodium glutamate (MSG) could lead to obesity. Recent research found that people who eat more MSG are more likely to be overweight or obese. What’s more, the link between high MSG intake and being overweight held even after accounting for the total number of calories people ate.

MSG is a widely used food additives. It is often present in processed foods although it is frequently not clearly labeled. MSG is frequently seen hiding behind such innocent-sounding names as hydrolyzed protein,
vegetable protein, soy protein isolate, soy protein concentrate, whey protein, and natural flavoring, spices, enzymes, autolyzed yeast extract, stock, broth and carrageenan. If MSG was as benign as the food industry says it is, why do they have to disguise the name.

Reuters reports:

“In the latest research, published in the American Journal of Clinical Nutrition, He and his colleagues followed more than 10,000 adults in China for about 5.5 years on average.

The researchers measured MSG intake directly by before-and-after weighing of products, such as bottles of soy sauce, to see how much people ate. They also asked people to estimate their intake over three 24-hour periods.

Men and women who ate the most MSG (a median of 5 grams a day) were about 30 percent more likely to become overweight by the end of the study than those who ate the least amount of the flavoring (less than a half-gram a day), the researchers found. After excluding people who were overweight at the start of the study, the risk rose to 33 percent.”

Measuring upper body strength is common in high school, college and professional level sports. Arguments have been made for and against this practice, but that’s for another day. The prime movers in the bench press are the pectoralis major, triceps brachii, anterior deltoid and medial deltoid. However the medial deltoid acts more like a stabilizer than a prime mover. Just for the record, the deltoid is one muscle; Anterior, medial and posterior simply describe areas, they aren’t separate heads.

Two of many ways one can perform a bench press is with a free weight barbell or a smith machine. The free weight bench forces the lifter to balance while exerting force to lift the weight. This higher level of instability is essential for a lifter who wants to engage the stabilizing muscles while training. A smith machine guides the bar in a fixed path and requires almost no balance by the lifter. The almost total lack of instability is thought by many to allow for increased force production of the prime movers. If this were true, bodybuilders or powerlifters who want to concentrate on the development of the prime movers, would be able to accomplish this with the smith machine. More-over, a lifter involved in rehab, novice lifters and elderly lifters may find the smith machine fits there needs because of the lack of instability.

A study published in the Journal of Strength and Conditioning Research compared the muscle activation between the free weight bench and the smith machine. The purpose of the study was to compare the muscle activation of the pectoralis major, anterior deltoid and medial deltoid during both exercises.

14 experienced and 12 inexperienced subjects were used in the study. Testing took place in two visits one week apart from each other, each consisting of either smith machine or free weight benching. Electromyography was used during the concentric phase of each lift at a lower intensity (2 reps at 70% of 1 rep max) and higher intensity (2 reps at 90% of 1 rep max) to compare muscle activation.

The study found no difference in the activation of the pectoralis major and the anterior deltoid between exercises regardless of load or experience. If the lack of instability of the smith machine allows the lifter to create more force production in the prime movers compared to the free weight bench press, it was not supported in this study. The authors surmise this may be due to the unnatural bar path of the smith machine in contrast to the free weight bench. Also, activation of the medial deltoid was significantly greater during the free weight bench regardless of load and experience. The instability of the free weight bench causes a greater activation of the medial deltoid as a force producer and stabilizer.

From a practical standpoint, according to the findings of this study, the free weight bench press may lead to a greater requirement of stabilization of the glenohumeral joint (shoulder). Increased shoulder stabilization is not only important for athletes but anyone involved in weight training, which requires strength and stability about the glenohumeral joint.

Do the findings of this study suggest dropping the smith machine from your training program and concentrating on free weight bench pressing? Absolutely not. The best thing one can do in regards to exercise choice, is mix things up. There are many exercises one can use in order to build their chest and shoulders. Don’t get caught in a rut using the same exercise over and over.

Chronic overeating and inactivity is definitely a path to an obese, unhealthy life. But, are we as a nation really eating that much more? According to surveys conducted in 1977-78 and 1994-96, reported daily caloric intake increased from 2239 Kcal (calories) to 2455 Kcal in men, and from 1534 Kcal to 1646 Kcal in women. Are these really enough calories to cause such massive decreases in the health of so many people? I don’t think so. There is one factor; however, that I believe is responsible for the greatest portion of the unhealthy state of our union. It’s not necessarily how much we’re eating, genetics or even a virus: It’s what we’re eating.

If a calorie is a calorie is a calorie, as most dieticians, nutritionists and doctors claim, why doesn’t the percent of increased caloric intake match the percentage of increase in overweight or obese individuals? The increase in calorie consumption in men and women has increased 7% and 9% respectively since the seventies. The increase in the percentage of individuals who are overweight or obese has increased almost 20% in each category. And remember, this increase literally occurred in less than 30 years, which is less than a generation. Why such a discrepancy between calories consumed and weight gained? Because there’s more to this epidemic than the amount of calories people are consuming.

The food processing industry has dropped the ball when it comes to supplying healthy food for our consumption. It is blatantly obvious by the ingredients listed in food labels coupled with the downward spiral of ill health in the U.S., the food industry is obsessed with increasing the bottom line with no regard for the negative effects of its products. It would be naive to assume that this billion dollar industry has the best intentions for our food’s safety and nutritive value.

Now don’t get me wrong, I am not trying to make excuses for people who don’t exercise and overeat. I know that the vast majority of overweight individuals eat excessive calories, however as stated above, the numbers just don’t add up.

On the-other-hand, the obesity epidemic and its related afflictions do have a linear relationship to the amount of denatured, devitalized, processed food people consume, especially simple sugars and vegetable oil.
