The following is a comprehensive paleo diet food list. In it, you'll find a list of paleo diet meats, vegetables, fruits, nuts, seeds, oils that are allowed on the paleo. Abstract. The Paleo diet is the healthiest way to eat because it is the only nutritional approach that works with genetics to help to stay lean, strong and energetic. Paleolithic diet or paleo diet, the food habits of humans during the Paleolithic Era (45,–40, to 10, BC) has got immense popularity in recent times.
Published online Nov. Klonoff, M. In a randomized crossover study spanning two consecutive 3-month study periods, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a diabetes diet in a cohort of patients with T2DM. What Is a Paleolithic Diet? The Paleolithic diet is also referred to as the caveman diet, Stone Age diet, and hunter—gatherer diet.
This diet consists of foods that are assumed to have been available to humans prior to the establishment of agriculture. The Paleolithic period began approximately 2. The period ended with the emergence of agriculture approximately 10, years ago.
The principal components of this diet are wild-animal source and uncultivated-plant source foods, such as lean meat, fish, vegetables, fruits, roots, eggs, and nuts.
The diet excludes grains, legumes, dairy products, salt, refined sugar, and processed oils, all of which were unavailable before humans began cultivating plants and domesticating animals. Observational studies of modern-day Paleolithic types of populations support a conclusion that a Paleolithic diet prevents obesity and metabolic syndrome.
The main ingredient lacking in a Paleolithic diet is calcium, which must be supplemented to prevent bone mineral loss. The appeal of this diet is that, since the advent of agriculture and animal domestication approximately 10, years ago, there has been little time for significant evolution of core metabolic and physiological processes in response to the major dietary changes introduced by these new food-producing practices.
Proponents of the Paleolithic diet believe that modern humans are genetically adapted to a Paleolithic diet and not to the current so-called civilized diet.
They believe that the modern so-called civilized diet may lead to chronic diseases such as T2DM, obesity, and cardiovascular disease, which are associated with societal affluence. The concepts of glycemic index and varied meals were taught with a visual meal-planning plate model.
Salt intake was recommended to be kept below 6 g per day. The diabetes diet differed from the Paleolithic diet, which was based on lean meat, fish, fruit, leafy and cruciferous vegetables, root vegetables, eggs, and nuts.
The Paleolithic diet excluded dairy products, cereal grains, beans, refined fats, sugar, candy, soft drinks, beer, and any extra addition of salt. The intake of other foods was not restricted and no advice was given with regard to proportions of food categories such as animal versus plant foods.
The evolutionary rationale for a Paleolithic diet and potential benefits were explained. The Paleolithic diet worked out to be lower in total energy, energy density, carbohydrate, dietary glycemic load, fiber, saturated fatty acids, and calcium but higher in unsaturated fatty acids, dietary cholesterol, and several vitamins and minerals.
Subjects consumed, for three months each, either a Paleolithic diet followed by a diabetes diet or the same two diets in the opposite order for three months each.
Compared to the diabetes diet, the Paleolithic diet resulted in statistically significant lower mean values of hemoglobin A1c, triglycerides, diastolic blood pressure, weight, body mass index, and waist circumference, while mean values for high-density lipoprotein were higher. The larger decrease of fasting plasma glucose following the Paleolithic diet nearly reached statistical significance, and systolic blood pressure also tended to decrease more following the Paleolithic diet.
The industrial revolution changed work in all walks of life.
Now machines do the hard work. And it is not just a question of fat and carbohydrates. The consumption of sodium salt is hugely greater today than ever before. These recommendations are roughly intermediate between current and ancestral human experience".
It is about how good the Paleolithic diet is as a solution to that problem. It is also about whether the argument behind the diet is a sound argument.
The information on the Paleolithic diet stated that it should be based on lean meat, fish, fruit, leafy and cruciferous vegetables, root vegetables, eggs and nuts, while excluding dairy products, cereal grains, beans, refined fats, sugar, candy, soft drinks, beer and extra addition of salt. The intake of other foods was not restricted and no advice was given with regard to proportions of food categories e. The evolutionary rationale for a Paleolithic diet and potential benefits were explained [ 19 ].
Evaluation An oral glucose tolerance test OGTT was performed in the morning after obtaining venous blood samples and measurements of blood pressure, weight and waist circumference in the primary care unit by UCB, GP or AH at study start, after 3 months when switching to a new diet and at the end of the study after 6 months.
Blood samples for plasma glucose and insulin during OGTT were obtained at 0, 15, 30, 60, 90 and minutes. The stimulated secretion was represented by the areas under the glucose and insulin curves using levels at 0 min as the base of the area.
A 4-day weighed food record on four consecutive days, including one weekend day, with weighing of each food item on a digital weighing scale that could be set to zero , was completed by the participants, starting 6 weeks after initiating each diet. GL and GI for the two diets were calculated. Underlying concept of dietary GL and dietary GI is food GI, introduced by Jenkins et al [ 22 ], reflecting the postprandial glucose response after a specific food rich in carbohydrate, expressing the quality of the carbohydrates.
Wolever and Jenkins also suggested the possibility of ranking diets based on dietary GI calculated from the proportional GI contribution of the included foods containing carbohydrate [ 23 ].
While dietary GI is expressing the quality of the carbohydrates consumed GL represent both the quantity and the quality of the carbohydrates consumed. Thus, dietary GL in this study was calculated as the result from multiplying available carbohydrate g for the food reported by the subjects during the 4-day weighed food record with the specific food's GI divided by Available carbohydrate was based on total carbohydrate minus dietary fibre.
Food's GI values glucose as reference were taken from the compilation by Foster-Powel et al [ 25 ].
Dietary GI was calculated as multiplied with dietary GL divided by the amount of available carbohydrate g in the diet.
Two-way paired t-test was used to analyze within-subject changes in absolute values, while two-way unpaired t-test was used to analyze between-subject changes in absolute values.
All outcome variables showed reasonable normal distribution in normal plots. Within-subject changes in outcome variables after first and second diet and within-subject changes in reported dietary intake during first and second diet were used to check for period effects [ 26 ].
Mean values of outcome variables and reported dietary intakes for the group starting with Paleolithic diet was compared with the group starting with Diabetes diet in order to check for carry-over effects [ 26 ]. Exploratory analyses were performed on outcome variables with significant effects from the Paleolithic diet as compared to the Diabetes diet.
Significantly correlating variables were entered into a stepwise forward linear regression analyses. Results Recruitment and participant flow The study started in January and the last participant was followed up in September after which the study was stopped.
Out of 26 subjects assessed for eligibility, nine were not eligible since they did not meet the inclusion criteria or refused to participate.
Out of the remaining 17 eligible subjects, who were all randomized and started on the study, four subjects were excluded for the following reasons: one starting with Paleolithic diet was wrongly included with ongoing warfarin treatment, one starting with Paleolithic diet was unwilling to continue due to abdominal pains and bloating, one starting with Diabetes diet was excluded after developing leukemia, and one starting with Diabetes diet was excluded after developing heart failure.
