Protein Intake The key for long term weight loss

Tuesday, April 1, 2014

Protein Intake: The key for long term weight loss ? - Long lasting weight loss is a subject which gets a ton of media attention day atfer day, with coverage on the television, magazines and newspapers.

Well, that weight lifter guzzling down a protein shake at your local fitness centre is onto something -- the latest cutting edge analysis reveals that doubling your personal protein consumption, coupled with working out, could be the key to losing fat pounds without losing lean muscle.

We all know a sufficient amount of protein (especially after a workout) is key to building and repairing muscular tissues, yet a recent analysis, circulated in the September issue of The FASEB Journal, suggests that we might not be having enough. The studys investigators placed 39 subjects on a weight-loss routine over 31 calendar days; to begin with, all of the participants were on the same exact diet plan to maintain their current body mass. After ten days, they were separated into 3 groups following calorie-restricted weight loss plans: those people that consumed the US-recommended daily allowance (RDA) of protein, individuals that ingested twice the RDA of required protein, and people who ate 3 times the RDA of necessary protein. The participants exercised accordingly in order to lose an average of a couple of lbs each week. The medical experts established that people that ingested double were likely to drop pounds without decreasing muscle tissue even while training on the weight loss diet. The individuals who ingested triple the quantity of required protein didnt experience any further weight loss than the double group.

If ever youre wanting to burn fat, decreasing lean muscle is precisely what you shouldnt be working at, as muscle burns up extra calories and boosts metabolism. Whilst the group was small, this well-controlled study demonstrates that if youre healthy and active, upping your own protein intake while limiting over-all calories could be the best option for short-term fat loss, the researchers state, even though they note you should still adhere to a well-balanced diet in the long term.

The RDA of necessary protein differs subject to how much you weigh and how active you are, but as an example, the RDA for a 130-pound active individual is 77 grams, meaning in accordance with this investigation you need to strive for 144 grams of protein every day if you are wanting to get in shape.

Heme Iron Intake Linked to Diabetes

Wednesday, March 26, 2014


Irons link to diabetes has been in the news over the last few years.

In February, 2004, a study that appeared in the Journal of the American Medical Association found that high levels of iron in the body almost tripled womens risk for developing diabetes. Researchers had examined iron stores in over 32,000 women who took part in the Nurses Health Study and followed them for 10 years.

Recently, a study which appears in this months issue of Diabetes Care found that women with high intakes of heme iron - the kind found primarily in meat - had a 28% greater risk of developing diabetes than women whose meat intake was lower. Researchers examined dietary intake of over 85,000 women who took part in the Nurses Health Study and followed them for 20 years.

One item to note - This recent study found no association between diabetes and iron intake from supplements, iron intake from non-heme sources (such as spinach and other greens, beans, and fortified cereals), or total iron intake from all sources. It could only document a link between diabetes and the intake of heme iron. (Heme iron is a constituent of hemoglobin and myoglobin molecules in animals. Only about 40% of the total iron supplied by meat is in the heme form.)

Although this study investigated irons association with the risk for developing diabetes, it did not reveal a mechanism, nor did it discuss what effect intake of heme iron would have in those already dealing with the disease. However, in an interview with Reuters Health, one of its authors theorized:
"In excess, these molecules create a state of "oxidative stress" that damages body cells over time. Oxidative stress could theoretically set the stage for diabetes by reducing body cells sensitivity to the hormone insulin, Rajpathak explained."
- More evidence ties iron intake to diabetes risk

College education and moderate alcohol intake linked to lower COPD risk

Tuesday, March 11, 2014



College education and alcohol consumption may be linked to risk for chronic obstructive pulmonary disease (COPD). Researchers from Kaiser Permanente Medical Group in Oakland, California, followed 126,019 people who supplied baseline data from 1978 – 1985 through 2008 with analyses of hospitalizations attributed to COPD (emphysema, chronic bronchitis, or chronic airway obstruction).

Although cigarette smoking, increasing age, and history of respiratory disease/symptoms were powerful predictors of COPD, results also showed that Asian Americans (vs whites) and college graduates (vs no college) were at a moderately lower risk for COPD, as were persons reporting 1 to 2 drinks per day (vs lifelong abstainers).

Prevent Cancer Lose Weight by Cutting Fat Intake

Sunday, February 23, 2014

(Article first published as Cut Fat, Lose Weight and Prevent Cancer on Technorati.)
There’s now yet another compelling reason to lose weight and cut consumption of unhealthy Omega-6 fats from vegetable sources. Research released from the Institute of Food Technologists indicates that as many as 1 in 3 cancer deaths could be prevented by reducing consumption of corn and vegetable oils and cutting calories.

It’s important to understand that fat itself is not the enemy, as it’s an essential nutrient required for normal cellular function. The problem arises when the balance of Omega-6 and Omega-3 fats are disproportional in our diet.

Humans have evolved with a 1:1 ratio of the two fat sources, yet our modern diet is closer to 20:1 in favor of Omega-6 fats. This causes a hormonal imbalance in the body which leads to inflammation, weight gain and increased risk of heart attack and many cancers. Monitoring Omega fat intake is an important first step which will assist with weight loss efforts and lead to reduced risk from many diseases.

Evolution Controls Our Diet
More than 750,000 people die from cancer annually, and the results from this study indicate that a quarter million lives could be spared with a concerted effort to control calories and Omega-6 fat consumption. Our genes are the product of thousands of years of evolution during times when Omega-3 fat sources such as fish and many nuts and seeds were plentiful. Every cell in our body relies on the critical Omega-3 components, EPA and DHA for replication and cell wall construction.

It’s only been during the past half century that Omega-6 fats from corn and vegetable sources have become an ever increasing part of our diet, and have now distorted the natural evolutionary ratio we require for optimal health. Omega-6 fats are very stable, allowing food to sit on store shelves for extended periods, and are present in virtually all processed foods.

Lower Omega-6 Fats by Cutting Processed and Fast Foods
Omega-6 fats are present in virtually every processed food on store shelves, with up to 90% of fat calories in our diet coming from this health endangering source. Take a two step approach to reduce Omega-6 calories and improve the ratio with Omega-3 fats.

Eliminate or drastically reduce foods which are packed with Omega-6 fats, including all commercially baked products, fast foods and vegetable based cooking oils. Be especially mindful to cut any foods listing hydrogenated trans fats, as these increase the risk of heart disease by 25%.

Increase Omega-3 Fat Sources to Lower Inflammation
Replace Omega-6 laden foods with Omega-3 healthy options. The best Omega-3 source is fish, as it provides the perfect balance of DHA and EPA, the two primary Omega-3 fats. Fish Oil supplements are a good choice for people who don’t enjoy fish.

Nuts and seeds also have smaller amounts of Omega-3 fats, with walnuts, flax and chia seeds rising to the top of the list. It’s important to remember that food from any fat source still contains 9 calories per gram, so be caul when substituting and track your daily calories with nutritional software.

Research is beginning to uncover the hidden dangers in the unnatural processed foods which make up a large portion of the Western diet. We are continually reminded that the foods we eat have a direct and immediate impact on our future health and body weight.

Monitor your food choices caully, paying close attention to the Omega fat ratios and switch to a reduced calorie lifestyle. You’ll enjoy the healthy benefits of dramatically lowered risk of cancer and many illnesses while you naturally maintain a healthy weight.

High Dietary Intake of Polyphenols Are Associated With Longevity

Thursday, February 20, 2014


It is the first time that a scientific study associates high polyphenols intake with a 30% reduction in mortality in older adults. The research, published on Journal of Nutrition, is the first to evaluate the total dietary polyphenol intake by using a nutritional biomarker and not only a food frequency questionnaire. Research is signed by Cristina Andrés Lacueva, Montserrat Rabassa and Mireia Urpí Sardà, from the Department of Nutrition and Bromatology of the UB; Raúl Zamora Ros (ICO-IDIBELL), and experts Antonio Cherubini (Italian National Research Centre on Aging), Stefania Bandinelli (Azienda Sanitaria di Firenze, Italy) and Luigi Ferrucci (National Institute on Ageing, United States).

Polyphenols: diet improves health

Polyphenols are naturally occurring compounds found largely in fruits, vegetables, coffee, tea, nuts, legumes and cereals. More than 8,000 different phenolic compounds have been identified in plants. Polyphenols have antioxidant, antiinflammatory, anticarcinogenic, etc. effects.

The research published on Journal of Nutrition is based on a 12-year follow-up of a population sample composed by 807 men and women aged 65 or over from Greve and Bagno (Tuscany, Italy), within the InCHIANTI study. The group of the UB analysed the effect of polyphenol-rich diets by means of a nutritional biomarker -- the total urinary polyphenol (TUP) concentration -- as a proxy measure of intake. To be exact, UB researchers contributes to first literature erences on TUP application to epidemiological or clinical studies.

New biomarkers for nutritional studies

Professor Cristina Andrés Lacueva, head of the Biomarkers and Nutritional & Food Metabolomics Research Group of the UB and coordinator of the study, explains that "the development and use of nutritional biomarkers enables to make a more precise and, particularly, more objective estimation of intake as it is not only based on participants memory when answering questionnaire. Nutritional biomarkers take into account bioavailabity and individual differences. According to the expert, "this methodology makes a more reliable and accurate evaluation of the association between food intake and mortality or disease risk."

In conclusion, the research proves that overall mortality was reduced by 30% in participants who had rich-polyphenol diets (>650 mg/day) in comparison with the participants who had low-polyphenol intakes (<500 mg/day).

Raúl Zamora Ros, first author of the study, points out that "results corroborate scientific evidence suggesting that people consuming diets rich in fruit and vegetables are at lower risk of several chronic diseases and overall mortality." Moreover, the research stresses the importance of evaluating -- if possible -- food intake by using nutritional biomarkers, not only food frequency questionnaires.

The Biomarkers and Nutritional & Food Metabolomics Research Group, which participates in the project Fun-C-Food (Consolider Ingenion), collaborates actively with several national and international research groups. It focuses its activity on the analysis of new more effective and sensitive nutritional biomarkers based on the bioavailabilty of bioactive compounds in food and their activity, in order to associate the intake of certain foods (consumption markers) with their potential effects on peoples health.
