What The World’s Healthiest Diets Have In Common
Retrieved 28 September Diet-to-Go has some really good plans that sound like they could work for you. Okinawa residents only ate modest amounts of seafood, lean meat, fruit and tea. Happy to help Tod…Thanks for reading! Archived from the original on 18 May

It's not what you'd think.


Meats include beef, pork, lamb and reindeer, while seafood includes herring, mackerel and salmon. The few desserts in the diet include baked goods made with oat bran, or jam for putting on top of cereal. Herbs include parsley, dill, mustard, horseradish and chives. A recent study published in The American Journal of Clinical Nutrition found that a healthy Nordic diet seemed to have an impact on genes in abdominal fat, turning off genes related to inflammation.

This low-calorie yet nutrition-dense diet is big on fruits and vegetables but sparse when it comes to meat, refined grains, sugar, salt and full-fat dairy. This diet came about in a very specific historical context: Sweet potatoes, rice although not as much as mainland Japanese people ate , green leafy vegetables, green and yellow vegetables like bitter melon, soybean-based foods like tofu and soy sauce.

Okinawa residents only ate modest amounts of seafood, lean meat, fruit and tea. Modern-day Okinawans are catching up economically with their mainland cousins, which means rates of obesity, metabolic syndrome and cardiovascular disease are rising as well. But the people who grew up eating traditionally are still alive and clinging to their culinary traditions. In fact, the island is home to one of the largest populations of centenarians in the world.

These super-seniors are living active lives largely free of disease and disability, and are said to age slowly. It prioritizes rice, noodles and whole grains, as well as fruits, vegetables, legumes, seeds and nuts as the most-eaten food groups.

Fish and shellfish are optional daily choices, while eggs and poultry should be eaten weekly. Note that recommended servings of red meat are smaller and less frequent monthly than even sweets weekly!

There are many different countries whose traditional ways of eating follow this model, but they all seem to have white rice as a staple. Asian countries have less incidences of obesity, cardiovascular disease and metabolic diseases like diabetes than Western countries, although that seems to be slowly changing thanks to rising economies and urbanization. Scientists are kind of scratching their heads at this one. The French have some of the lowest obesity rates in the developed world and highest life expectancies, despite the rich food they eat.

Full-fat cheese and yogurt, butter, bread, and small but regular amounts of cheese and chocolate are some of the hallmarks of this rich diet. If you want to play it safe, maybe try adopting how French people eat, instead of what they eat, if you want to get healthier in the new year. Get top stories and blog posts emailed to me each day.

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.

Eckel , past president, noted that a low-carbohydrate diet could potentially meet AHA guidelines if it conformed to the AHA guidelines for low fat content. The position statement by the Heart Foundation regarding low-carbohydrate diets states: Low-carbohydrate diets became a major weight loss and health maintenance trend during the late s and early s.

Because of the substantial controversy regarding low-carbohydrate diets, and even disagreements in interpreting the results of specific studies, it is difficult to objectively summarize the research in a way that reflects scientific consensus.

Although there has been some research done throughout the twentieth century, most directly relevant scientific studies have occurred in the s and early s and, as such, are relatively new and the results are still debated in the medical community. A systematic review studying the effects of a low-carbohydrate diet LCD on weight loss and cardiovascular risk factors showed that the diet that was studied was associated with significant decreases in body weight, body mass index , abdominal circumference, blood pressure , triglycerides , fasting blood sugar , blood insulin and plasma C-reactive protein , as well as an increase in high-density lipoprotein cholesterol HDL.

Low-density lipoprotein cholesterol LDL and creatinine did not change significantly. The study found the LCD was shown to have favorable effects on body weight and major cardiovascular risk factors but concluded the effects on long-term health are unknown.

The study did not compare health benefits of LCD to low-fat diets. A meta-analysis published in the American Journal of Clinical Nutrition in compared low-carbohydrate, Mediterranean, vegan, vegetarian, low-glycemic index, high-fiber, and high-protein diets with control diets. The researchers concluded that low-carbohydrate, Mediterranean, low-glycemic index, and high-protein diets are effective in improving markers of risk for cardiovascular disease and diabetes.

Advocates of low-carbohydrate diets generally dispute any suggestion that such diets cause weakness or exhaustion except in the first few weeks as the body adjusts , and indeed most highly recommend exercise as part of a healthy lifestyle. Some critics imply or explicitly argue that vegetables and fruits are inherently all heavily concentrated sources of carbohydrates so much so that some sources treat the words 'vegetable' and 'carbohydrate' as synonymous.

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. Most vegetables are low- or moderate-carbohydrate foods in the context of these diets, fiber is excluded because it is not a nutritive carbohydrate.

Some vegetables, such as potatoes , have high concentrations of starch, as do maize and rice. Most low-carbohydrate diet plans accommodate vegetables such as broccoli , spinach , cauliflower , and peppers.

Nevertheless, debate remains as to whether restricting even just high-carbohydrate fruits, vegetables, and grains is truly healthy. Contrary to the recommendations of most low-carbohydrate diet guides, some individuals may choose to avoid vegetables altogether to minimize carbohydrate intake. Low-carbohydrate vegetarianism is also practiced. Raw fruits and vegetables are packed with an array of other protective chemicals, such as vitamins, flavonoids , and sugar alcohols.

Some of those molecules help safeguard against the over-absorption of sugars in the human digestive system. Some evidence indicates the increasingly large percentage of calories consumed as refined carbohydrates is positively correlated with the increased incidence of metabolic disorders such as type 2 diabetes. Some evidence indicates the human brain — the largest consumer of glucose in the body — can operate more efficiently on ketone bodies.

In , the Canadian government ruled that foods sold in Canada could not be marketed with reduced or eliminated carbohydrate content as a selling point, because reduced carbohydrate content was not determined to be a health benefit. The government ruled that existing "low carb" and "no carb" packaging would have to be phased out by In , John Rollo reported on the results of treating two diabetic Army officers with a low-carbohydrate diet and medications.

A very low-carbohydrate, ketogenic diet was the standard treatment for diabetes throughout the nineteenth century. In , William Banting , a formerly obese English undertaker and coffin maker, published "Letter on Corpulence Addressed to the Public", in which he described a diet for weight control giving up bread , butter , milk , sugar , beer , and potatoes. In the early s Frederick Madison Allen developed a highly restrictive short term regime which was described by Walter R. The process was halted if sugar appeared in the person's urine.

In , Richard Mackarness M. Mackarness also challenged the "calorie theory" and referenced primitive diets such as the Inuit as examples of healthy diets with a low-carbohydrate and high-fat composition. The "Stillman diet" is a high-protein , low-carbohydrate, and low-fat diet. It is regarded as one of the first low-carbohydrate diets to become popular in the United States. In , Robert Atkins published Dr. Atkins Diet Revolution , which 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.

The concept of the glycemic index was developed in by David Jenkins to account for variances in speed of digestion of different types of carbohydrates.

In the s, Atkins published an update from his book, Dr. 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.

In the United States, the diet has continued to garner attention in the medical and nutritional science communities, and also has inspired a number of hybrid diets that include traditional calorie-counting and exercise regimens.

Far from faddish, diets based on carbohydrate restriction have been the historical treatment for diabetes and are still supported by basic biochemistry, and it is argued that they should be considered the "default" diet, the one to try first, in diseases of carbohydrate intolerance or insulin resistance.
