Well, he eats more grass. For human beings, we have a species-specific diet. This entails fruits and vegetables being our foods. An inactive person eats less fruit and vegetables.
But a person eats fruits and vegetables.
Can you talk about that? The narrators tell us a lot of information about the athletes, I guess maybe as filler, or human interest, or however we want to call it.
One of the things they talk about is the various illnesses that athletes have had to overcome. Eventually I started doing my homework on this, because it interested me, and I realised that athletes in general are very ill.
But a lot of their illnesses fall into specific categories. We find actually that the cancer rate among athletes is higher than it is amongst the general population of the same age group individuals.
We think of athletes as adults, but really, our athletes are generally somewhere from mid-teens to 30 or mids. They have higher kidney disease. They have a bunch of specific ailments that tend to come on them.
Eventually, something has to fail. Eventually kidneys fail or liver fails. As a result, athletes are stressing their liver and kidneys really hard.
If you look at, for instance, Tour de France every day, it gives you a list of the athletes that are out due to illness. Almost all of them are out due to digestive disorders. And when you are out of the race, you can no longer help your team, and your chance of winning is reduced to zero. If athletes eat poorly, they end up with digestive disorders. Tour riders eat roughly quadruple what we eat. You do have to build up gradually. Actually, many people tell me they have trouble digesting vegetables.
Individuals who better adapt to high levels of training usually experience greater gains from training over time which can lead to improved performance.
Consequently, the FDA monitored the manufacturing processes, quality, and labeling of dietary supplements. However, many people felt that the FDA was too restrictive in regulating dietary supplements. The law defined a "dietary supplement" as a product taken by mouth that contains a "dietary ingredient" intended to supplement the diet. Dietary supplements may also be extracts or concentrates from plants or foods. Dietary supplements are typically sold in the form of tablets, capsules, soft gels, liquids, powders, and bars.
Products sold as dietary supplements must be clearly labeled as a dietary supplement. Dietary supplement ingredients that were lawfully sold prior to , have been "grandfathered" into the Act, meaning that a manufacturer is not required to submit to FDA the evidence it relies upon to substantiate safety or effectiveness before or after it markets these ingredients.
The rationale for this exclusion is based on a long history of safe use; hence there is no need to require additional safety data.
A new dietary ingredient is deemed adulterated and subject to FDA enforcement sanctions unless it meets one of two exemption criteria: either 1. The second criterion, applicable only to new dietary ingredients that have not been present in the food supply, requires manufacturers and distributors of a new dietary ingredient or a product containing a new dietary ingredient to submit pre-market notification to the FDA.
This notification, which must be submitted at least 75 days before the product is introduced into interstate commerce, must contain information that provides a history of use or other evidence of safety establishing that the dietary ingredient, when used under the conditions recommended or suggested in the labeling of the dietary supplement will "reasonably be expected to be safe.
The FTC also requires that any representations or claims made about the supplement be substantiated by adequate evidence to show that they are not false or misleading, a policy which is also shared by the FDA. They may describe the role of a nutrient or dietary ingredient intended to affect normal structure or function in humans, they may characterize the means by which a nutrient or dietary ingredient acts to maintain such structure or function, they may describe general well-being from consumption of a nutrient or dietary ingredient or they may describe a benefit related to a nutrient deficiency disease, as long as the statement also tells how widespread such a disease is in the United States.
This product is not intended to diagnose, treat, cure, or prevent any disease".
Opponents of dietary supplements often cite this statement as evidence that the FDA did not review or approve the dietary supplement when in fact most dietary ingredients have been grandfathered in due to a long history of safe sale; whereas those products containing a new dietary ingredient which is not present in the food supply as an article used for food in a form in which the food has not been chemically altered are subject to pre-market notification to FDA regarding history of use or other evidence of safety.
Unfortunately, a large number of new dietary ingredients requiring pre-market notification have been introduced into dietary supplements since October without the requisite notification. However, since the law was passed it has only approved a few claims. Shalala et al in After years of litigation, the U. Court of Appeals for the District of Columbia Circuit ruled in that qualified health claims may now be made about dietary supplements with approval by FDA as long as the statements are truthful and based on science.
Supplement or food companies wishing to make health claims about supplements can submit research evidence to the FDA for approval of a health claim. Government or the National Academy of Sciences; such claims may be used after submission of a health claim notification to FDA; and the FDA Consumer Health Information for Better Nutrition Initiative provided for qualified health claims where the quality and strength of the scientific evidence falls below that required for FDA to issue an authorizing regulation.
Such health claims must be qualified to assure accuracy and non-misleading presentation to consumers. More recently, the U. The purpose of this non-profit foundation is to lead collaborations among the FDA, academic research institutions, and industry to enhance research in evaluating the safety and efficacy of dietary supplements as well as to improve the quality and management of these products. For many years, manufacturers and distributors of dietary supplements were not required to record, investigate or forward to FDA any reports they receive on injuries or illnesses that may be related to the use of their products.
Reports of "serious" adverse events i. While these reports are unsubstantiated; can be influenced by media attention to a particular supplement; and do not necessarily show a cause and effect: they can be used by the company and FDA to monitor trends and "signals" that may suggest a problem. Once a dietary supplement product is marketed, the FDA has the responsibility for showing that the dietary supplement is unsafe before it can take action to restrict the product's use or removal from the marketplace.
The FTC maintains responsibility to make sure manufacturers are truthful and not misleading regarding claims they make about dietary supplements.
The FDA has the power to remove supplements from the market if it has sufficient scientific evidence to show the supplement is unsafe. This includes acting against companies if the ingredients found in the supplement do not match label claims or in the event undeclared, drug ingredients are present e.
While this does not ensure the safety of dietary supplements, it does provide a means for governmental oversight of the dietary supplement industry if adequate resources are provided to enforce DSHEA.
80/10/10: Best Foods to Boost Energy and Athletic Performance? (Part 3)
Since the inception of DSHEA, the FDA has required a number of supplement companies to submit evidence showing safety of their products and acted to remove a number of products sold as dietary supplements from sale in the United States due to safety concerns.
Further, they must have evidence that the ingredients sold in their supplements are generally safe if requested to do so by the FDA. They also consult with marketing and legal teams with the responsibility to ensure structure and function claims do not misrepresent results of research findings. This has increased job opportunities for sports nutrition specialists as well as enhanced external funding opportunities for research groups interested in exercise and nutrition research.
This trend toward greater research support is the result of: 1. Attempts to honestly and accurately inform the public about results; 2. To provide scientific evidence to support advertising claims and increase sales. This trend is due in part to greater scrutiny from the FDA and FTC, but also in response to an increasingly competitive marketplace where established safety and efficacy attracts more consumer loyalty and helps ensure a longer lifespan for the product in commerce.

In our experience, companies who adhere to these ethical standards prosper while those who do not struggle to comply with FDA and FTC guidelines and rapidly lose consumer confidence, signaling an early demise for the product.
Product Development and Quality Assurance One of the most common questions raised by athletes, parents, and professionals regarding dietary supplements relates to how they are manufactured and consumer awareness of supplement quality.
In a number of cases, reputable companies who develop dietary supplements have research teams who scour the medical and scientific literature looking for potentially effective nutrients. These research teams often attend scientific meetings and review the latest patents, research abstracts presented at scientific meetings, and research publications.
They may also consult with leading researchers to discuss ideas about dietary supplements that can be commercialized. Leading companies invest in basic research on nutrients before developing their supplement formulations. Others wait until research has been presented in patents, research abstracts, or publications before developing nutritional formulations featuring the nutrient.
Sometimes, companies develop and patent new processing and purification processes because the nutrient has not yet been extracted in a pure form or is not available in large quantities.
Nutrition and Athletic Performance
Reputable raw material manufacturers conduct extensive tests to examine purity of their raw ingredients.
If the company is working on a new ingredient, they often conduct toxicity studies on the new nutrient once a purified source has been identified.
They would then compile a safety dossier and communicate it to the FDA as a New Dietary Ingredient submission, with the hopes of it being allowed for lawful sale. When a powdered formulation is designed, the list of ingredients and raw materials are typically sent to a flavoring house and packaging company to identify the best way to flavor and package the supplement. In the nutrition industry, there are several main flavoring houses and packaging companies who make a large number of dietary supplements for dietary supplement companies.
Most reputable dietary supplement manufacturers submit their production facilities to inspection from the FDA and adhere to good manufacturing practices GMP's , which represent industry standards for good manufacturing of dietary supplements. Some companies also submit their products for independent testing by third-party companies to certify that their products meet label claims.
For example, NSF's certification service includes product testing, GMP inspections, ongoing monitoring and use of the NSF Mark indicating products comply with inspection standards, and screening for contaminants. More recently, companies have subjected their products for testing by third party companies to inspect for banned or unwanted substances. These types of tests help ensure that each batch of the dietary supplement does not contained substances banned by the International Olympic Committee or other athletic governing bodies e.
While third-party testing does not guarantee that a supplement is void of banned substances, the likelihood is much less e. Moreover, consumers can request copies of results of these tests. In our experience, companies who are not willing to provide copies of test results are not worth downloading. The following are recommended questions to ask when evaluating the potential ergogenic value of a supplement.
Does The Theory Make Sense? Based on these preliminary studies, a training device or supplement is often marketed to people proclaiming the benefits observed in these basic research studies.
By evaluating the literature on your own you can discern whether a supplement has been based on sound scientific evidence or not.
A quick look at these references will often help determine if the theory is plausible or not. The next question to ask is whether there is any well-controlled data showing effectiveness of the proposed ergogenic aid works as claimed in athletes or people involved in training.
The first place to look is the list of references cited in marketing material supporting their claims. We then critically evaluate the abstracts and articles by asking a series of questions.
Studies reporting improved performance in rats or persons with type 2 diabetes may be insightful but research conducted on non-diabetic athletes is much more practical and relevant.
Were the studies well controlled? For ergogenic aid research, the study should be a placebo controlled, double-blind, and randomized clinical trial if possible. This means that neither the researcher's nor the subject's were aware which group received the supplement or the placebo during the study and that the subjects were randomly assigned into the placebo or supplement group.
An additional element of rigor is called a cross-over design, where each subject, at different times separated by an interval known as a "washout period" , is exposed to each of the treatments.
While utilization of a cross-over design is not always feasible, it removes the element of variability between subjects and increases the strength of the findings. At times, supplement claims have been based on poorly designed studies i. Well-controlled clinical trials provide stronger evidence as to the potential ergogenic value.The author recommends a daily regimen which includes fruit for breakfast and lunch and before dinner.
Live life in total health, vitality, increased performance, with energy to spare - without starving yourself, taking supplements or meal replacements. The primary thrust behind public disclosures of potential conflicts of interest is the prevention of a later revelation of an interest that has the potential of discrediting the study in question, the authors, and even the research center or institution where the study was conducted.
