Although such diet recommendations mostly involve lowering nutritive carbohydrates, some low-carbohydrate foods are discouraged, as well e. A systematic review of 62, participants in 10 dietary trials found that reducing dietary fat intake had no effect on coronary heart disease and had no effect on overall mortality.
The authors of this meta-analysis conclude that the available evidence from randomized controlled trials does not support the recommendation of the - Dietary Guidelines for Americans that people reduce their fat intake. Mortality[ edit ] As of it appeared that with respect to the risk of death for people with cardiovascular disease, the kind of carbohydrates consumed are important; diets relatively higher in fiber and whole grains lead to reduced risk of death from cardiovascular disease.
Highly refined-grain diets do not. Fiction" campaign inthe ADA stated: Excess calories from carbohydrates are not any more fattening than calories from other sources.
Some of these diets restrict healthful foods that provide essential nutrients and don't provide the variety of foods needed to adequately meet nutritional needs. People who stay on these diets very long may not get enough vitamins and minerals and face other potential health risks. Eckelpast president, noted that a low-carbohydrate diet could potentially meet AHA guidelines if it conformed to the AHA guidelines for low fat content.
Thus, in absolute terms, even sweet fruits and berries do not represent a significant source of carbohydrates in their natural form, and also typically contain a good deal of fiber which attenuates the absorption of sugar in the gut.
Some vegetables, such as potatoeshave high concentrations of starch, as do maize and rice. Most low-carbohydrate diet plans accommodate vegetables such as broccolispinachcauliflowerand peppers. Nevertheless, debate remains as to whether restricting even just high-carbohydrate fruits, vegetables, and grains is truly healthy.
Low-carbohydrate vegetarianism is also practiced. Raw fruits and vegetables are packed with an array of other protective chemicals, such as vitamins, flavonoidsand sugar alcohols. Some of those molecules help safeguard against the over-absorption of sugars in the human digestive system.
The government ruled that existing "low carb" and "no carb" packaging would have to be phased out by A very low-carbohydrate, ketogenic diet was the standard treatment for diabetes throughout the nineteenth century. The process was halted if sugar appeared in the person's urine.
The "Stillman diet" is a high-proteinlow-carbohydrate, and low-fat diet. It is regarded as one of the first low-carbohydrate diets to become popular in the United States. InRobert Atkins published Dr. Atkins Diet Revolutionwhich advocated the low-carbohydrate diet he had successfully used in treating patients in the s having developed the diet from a article published in JAMA.
Atkins New Diet Revolution, and other doctors began to publish books based on the same principles. This has been said to be the beginning of what the mass media call the "low carb craze" in the United States.Our primarily meta-analytic findings show that there is a significant positive association between board size, board composition, audit committee and voluntary disclosure, while CEO duality has a significant negative effect on voluntary disclosure.

To date, the results of agency theory-based research exploring the impact of board composition on firms’ critical decisions are equivocal. Through meta-analyses, this study reveals systematic relationships between board composition and six of the seven critical decisions examined.
Interestingly, the results provide little support to agency theory’s predictions on the impact of board. In general, neither board composition nor board leadership structure has been consistently linked to firm financial performance.
In response to these findings, we provide meta-analyses of 54 empirical studies of board composition ( samples, n = 40,) and 31 empirical studies of board leadership structure (69 samples, n = 12,) and their relationships to firm financial performance.
Our meta-analytic findings show that country geographic location moderates the association between board size, board composition, CEO duality and voluntary disclosure. In addition, we find that the level of investor protection, the type and the method of disclosure affect the relationship between CEO duality and voluntary disclosure.
Definition and classification. Low-carbohydrate diets are not well-defined.
As of the conflicting definitions of "low-carbohydrate" diets have complicated research into the subject.. The American Academy of Family Physicians defines low-carbohydrate diets as diets that restrict carbohydrate intake to 20 to 60 grams per day, typically less than 20% of caloric intake.
