Can You Get Too Much Protein?

Continue Reading 0

Posted 15 September 2021

Protein has achieved a venerated status in the dietary world for everything from building muscle to preventing weight gain. But can you get too much of a good thing?

Protein powders that come in chocolate, strawberry, and cookies and cream flavors are doled out by the scoopful and mixed into smoothies, making it possible to effortlessly consume protein in amounts that far exceed dietary recommendations. A canned protein drink can contain almost as much protein as an eight-ounce steak, and snack bars or a small bag of protein chips can pack more of the macronutrient than a three-egg omelet.

But while some nutritionists have encouraged the protein craze, a number of experts are urging caution. They point out that protein powders and supplements, which come from animal products like whey and casein (byproducts of cheese manufacturing)

Banned stimulants found in weight loss and sports supplements

Banned stimulants found in weight loss and sports supplements Deterenol is a pharmaceutical bronchodilator that the U.S. Food and Drug Administration (FDA) never approved as a drug for humans. The FDA determined in 2004 that deterenol is not permitted as an ingredient in dietary supplements. Although since 2018, deterenol has been detected in several brands of dietary supplements sold in the U.S., the FDA has not advised manufacturers to remove it from products or warned consumers to avoid supplements labeled as containing the drug. In April 2018, researchers made online purchases of 35 samples of 17 brands of supplements labeled as containing deterenol (or a synonym) to determine the presence and quantity of active pharmaceutical stimulants that have not been approved by the FDA for oral use.

The researchers found:

  • Eight of the brands were marketed for weight loss, six as sports/energy supplements, and three with

Cape Town – Marketed as a miracle weight-loss supplement targeting the bodybuilding community, the illegal drug DNP (2,4-Dinitrophenol) is widely available on the black market and doctors are warning that users often pay for their rapid weight loss with their lives.

It’s illegal and potentially lethal, yet unscrupulous sellers are promoting it as a “miracle fat burner”. DNP is said to accelerate the basal metabolic rate, thereby raising the internal body temperature, which can lead to rapid weight loss.

DNP is an industrial chemical, first used during World War I by the French in explosives production. It’s been used as a pesticide, a wood preserver and even a dye.

In 1933, scientists from Stanford University discovered the compound had some fat-shredding properties. It was then marketed as a miracle over-the-counter weight loss drug until reports of adverse effects such

DNP (2,4-dinitrophenol) is an industrial chemical used in making explosives, but sold with the claim that it is an effective fat burning drug. In South Africa, dinitrophenol is listed in Schedule 4, so is a prescription-only substance. Is that sufficient to prevent unauthorised access, as described in this Guardian story. And why is https://www.anabolics-sa.co.za/product/dnp/ flagrantly selling this product, in spite of bizarrely warning: “beyond dangerous is almost an understatement.’

‘Knowing it could kill you isn’t a deterrent’: the deadly trade in diet pills

DNP is an industrial chemical used in making explosives. If swallowed, it can cause a horrible death – and yet it is still being aggressively marketed to vulnerable people online.

Sports nutrition position paper backs dietary protein over supplements

Continue Reading 0

There is no physical reason for athletes to increase protein intake with supplements, says the German Nutrition Society (DGE), who recommend a balanced diet to achieve all protein requirements.

In the last of seven position papers by the society, the paper recommends that protein intake depending on training conditions and goals should be at approx. 1.2-2.0 grams per kilogram (g /kg) body weight.

Regarding supplementation. Dr Helmut Heseker, professor of nutritional science at the university of Paderborn states, “In the everyday nutritional routine of athletes there is no physiological reason to supplement protein intake with supplements and a balanced diet is usually superior to supplements.”

When Teen Boys Use Supplements

“I’ve started cutting,” my son, a college freshman, recently told me. He meant he was temporarily restricting calories to lose body fat as part of his new focus on bodybuilding. He planned to alternate cutting with “bulking,” or building up muscle mass, aided by over-the-counter supplements like protein powder and creatine.

Everything he was doing was legal, but was it safe? I also have a teenage daughter, and I was attuned to body-image-related issues affecting girls. But I realized the risks for teenage boys were equally worrisome and decided to check with several experts.

“Almost a third of boys are trying to gain weight or bulk up,” said Dr. Jason Nagata, an assistant professor of pediatrics at the University of California, San Francisco.

Many turn to protein supplements in an attempt to

The edge. Every athlete, from the professional to the weekend warrior, strives to obtain that ever-elusive element that leads to victory—sometimes sparing no expense to get there.

A lighter bike, a better training regimen, the newest shoes.

A recently released study from the University of Montana, however, has discovered that common “edge,” sports nutrition products, are no more effective at promoting  in female athletes as regular, carbohydrate-rich, often less-expensive potato-based foods.

“Athletes are vulnerable to strategic marketing. We are easily swayed,” said UM Research Professor Brent Ruby, a veteran endurance  who knows all too well the allure of sports powders and gels.

As director of UM’s Montana Center for Work Physiology and Exercise Metabolism, Ruby and his team have done extensive work in the field of athletic performance and examining the role that post-exercise carbohydrate nutrition plays in the replenishing Read the rest

Posted 11 December 2019

Piracetam has been touted as a brain-enhancing substance despite poor evidence of its efficacy. Although it is not approved as a drug and is prohibited as a dietary supplement ingredient in the United States, U. S.-based researchers were able to purchase two samples of each of 12 brands of piracetam products online from sellers they identified through a Google search.

Reference: Cohen P and others. Presence of piracetam in cognitive enhancement dietary supplements. JAMA Internal Medicine. doi:https://doi.org/10.1001/jamainternmed.2019.5507, Nov 25, 2019

Five of those brands were labeled as dietary supplements. Chemical analysis revealed that the piracetam content ranged from 85% to 188% of the labeled dosage. The researchers noted that (a) known adverse effects of piracetam include anxiety, insomnia, agitation, depression, drowsiness, and weight gain, and (b) the effects of the doses found, particularly in elderly consumers with poor kidney function are unknown.

South African Whey and Casein protein powders lack important amino acids

Posted 07 November 2019

This South African study found that  the the majority of 100% Whey or Casein protein powders, e.g. made by USN, Nutritech, Evox , do not contain the levels of protein as indicated on the label. But more seriously, these products claim to build muscle – but have been stripped of essential amino acids so they are not “proper proteins” and therefore, cannot do so, but can only be utilised as fuel.
