Gluten-free

gluten

A gluten-free diet is a diet that excludes foods containing gluten. Gluten is a protein complex found in wheat (including ancient varieties: kamut and spelt), barley, rye, and triticale (a wheat/rye hybrid). A gluten-free diet is the only medically accepted treatment for celiac disease (an autoimmune disorder of the small intestine that occurs in genetically predisposed people of all ages).

Being gluten intolerant can often mean a person may also be wheat intolerant as well as suffer from the related inflammatory skin condition dermatitis herpetiformis (chronic blistering). A smaller minority of people who suffer from wheat intolerance alone are tolerant to gluten. Despite unknown benefits for the general population, and evidence to suggest adverse effects, a significant demand has developed for gluten-free food in the United States.

Paleo Diet

The paleolithic diet (also popularly referred to as the caveman diet, Stone Age diet, and hunter-gatherer diet) is a modern nutritional plan based on the presumed ancient diet of wild plants and animals that various hominid species habitually consumed during the Paleolithic era—a period of about 2.5 million years which ended around 10,000 years ago with the development of agriculture and grain-based diets.

In common usage, such terms as the ‘Paleolithic diet’ also refer to the actual ancestral human diet. Centered on commonly available modern foods, the ‘contemporary’ Paleolithic diet consists mainly of fish, grass-fed pasture raised meats, eggs, vegetables, fruit, fungi, roots, and nuts, and excludes grains, legumes, dairy products, potatoes, refined salt, refined sugar, and processed oils.

Yo-yo Dieting

fat pull by jon schwarz

Yo-yo dieting, also known as ‘weight cycling,’ is a term coined by Kelly D. Brownell, Ph.D., at Yale University. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again.

The reasons for yo-yo dieting are varied but often include embarking upon a hypocaloric diet that was initially too extreme. At first the dieter may experience elation at the thought of their rejection of food. Over time, however, the limits imposed by such extreme diets cause effects such as depression or fatigue that make the diet impossible to sustain. Ultimately, the dieter reverts to their old eating habits, now with the added emotional effects of failing to lose weight by restrictive diet. Such an emotional state leads many people to eating more than they would have before dieting, causing them to rapidly regain weight.

Keto

diet

The ketogenic [kee-toh-jen-ikdiet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control epilepsy in children. The diet mimics aspects of starvation by forcing the body to burn fats rather than carbohydrates.

Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fuelling brain function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures.

Ital

ital shack

Ital or I-tal is the dietary system associated with the Rastafari movement. The word derives from the English word ‘vital,’ with the initial syllable replaced by i. This is done to many words in the Rastafari vocabulary to signify the unity of the speaker with all of nature. Rastafarians derive their beliefs and morality from intense personal meditations and prayer, and therefore there is no single dogma of Rastafarian belief. Due to this emphasis on individual personal meditation in Rastafari, the expression of Ital eating varies widely from Rasta to Rasta, and there are few universal ‘rules’ of Ital living.
