Paleolithic nutrition improves plasma lipid concentrations of hypercholesterolemic adults to a greater extent than traditional heart-healthy dietary recommendations.

Abstract Title: Paleolithic nutrition improves plasma lipid concentrations of hypercholesterolemic adults to a greater extent than traditional heart-healthy dietary recommendations. Abstract Source: Nutr Res. 2015 Jun ;35(6):474-9. Epub 2015 May 14. PMID: 26003334 Abstract Author(s): Robert L Pastore, Judith T Brooks, John W Carbone Article Affiliation: Robert L Pastore Abstract: Recent research suggests that traditional grain-based heart-healthy diet recommendations, which replace dietary saturated fat with carbohydrate and reduce total fat intake, may result in unfavorable plasma lipid ratios, with reduced high-density lipoprotein (HDL) and an elevation of low-density lipoprotein (LDL) and triacylglycerols (TG). The current study tested the hypothesis that a grain-free Paleolithic diet would induce weight loss and improve plasma total cholesterol, HDL, LDL, and TG concentrations in nondiabetic adults with hyperlipidemia to a greater extent than a grain-based heart-healthy diet, based on the recommendations of the American Heart Association. Twenty volunteers (10 male and 10 female) aged 40 to 62 years were selected based on diagnosis of hypercholesterolemia. Volunteers were not taking any cholesterol-lowering medications and adhered to a traditional heart-healthy diet for 4 months, followed by a Paleolithic diet for 4 months. Regression analysis was used to determine whether change in body weight contributed to observed changes in plasma lipid concentrations. Differences in dietary intakes and plasma lipid measures were assessed using repeated-measures analysis of variance. Four months of Paleolithic nutrition significantly lowered (P<.001) mean total cholesterol, LDL, and TG and increased (P<.001) HDL, independent of changes in body weight, relative to both baseline and the traditional heart-healthy diet. Paleolithic nutrition offers promising potential for nutritional management of hyperlipidemia in adults whose lipid profiles have not improved after following more traditional heart-healthy dietary recommendations.

Plant-rich mixed meals based on Palaeolithic diet principles have a dramatic impact on incretin, peptide YY and satiety response, but show little effect on glucose and insulin homeostasis: an acute-effects randomised study. 📎

Abstract Title: Plant-rich mixed meals based on Palaeolithic diet principles have a dramatic impact on incretin, peptide YY and satiety response, but show little effect on glucose and insulin homeostasis: an acute-effects randomised study. Abstract Source: Br J Nutr. 2015 Feb 28 ;113(4):574-84. Epub 2015 Feb 9. PMID: 25661189 Abstract Author(s): H Frances J Bligh, Ian F Godsland, Gary Frost, Karl J Hunter, Peter Murray, Katrina MacAulay, Della Hyliands, Duncan C S Talbot, John Casey, Theo P J Mulder, Mark J Berry Article Affiliation: H Frances J Bligh Abstract: There is evidence for health benefits from 'Palaeolithic' diets; however, there are a few data on the acute effects of rationally designed Palaeolithic-type meals. In the present study, we used Palaeolithic diet principles to construct meals comprising readily available ingredients: fish and a variety of plants, selected to be rich in fibre and phyto-nutrients. We investigated the acute effects of two Palaeolithic-type meals (PAL 1 and PAL 2) and a reference meal based on WHO guidelines (REF), on blood glucose control, gut hormone responses and appetite regulation. Using a randomised cross-over trial design, healthy subjects were given three meals on separate occasions. PAL2 and REF were matched for energy, protein, fat and carbohydrates; PAL1 contained more protein and energy. Plasma glucose, insulin, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic peptide (GIP) and peptide YY (PYY) concentrations were measured over a period of 180 min. Satiation was assessed using electronic visual analogue scale (EVAS) scores. GLP-1 and PYY concentrations were significantly increased across 180 min for both PAL1 (P= 0·001 and P< 0·001) and PAL2 (P= 0·011 and P= 0·003) compared with the REF. Concomitant EVAS scores showed increased satiety. By contrast, GIP concentration was significantly suppressed. Positive incremental AUC over 120 min for glucose and insulin did not differ between the meals. Consumption of meals based on Palaeolithic diet principles resulted in significant increases in incretin and anorectic gut hormones and increased perceived satiety. Surprisingly, this was independent of the energy or protein content of the meal and therefore suggests potential benefits for reduced risk of obesity. Article Published Date : Feb 27, 2015

Diet in acne: further evidence for the role of nutrient signalling in acne pathogenesis. 📎

Abstract Title: Diet in acne: further evidence for the role of nutrient signalling in acne pathogenesis. Abstract Source: Acta Derm Venereol. 2012 May ;92(3):228-31. PMID: 22419445 Abstract Author(s): Bodo C Melnik Article Affiliation: Department of Dermatology, Environmental Medicine and Health Theory, University of Osnabrück, Osnabrück, Germany. This email address is being protected from spambots. You need JavaScript enabled to view it. Abstract: Recent evidence underlines the role of Western diet in the pathogenesis of acne. Acne is absent in populations consuming Palaeolithic diets with low glycaemic load and no consumption of milk or dairy products. Two randomized controlled studies, one of which is presented in this issue of Acta Dermato-Venereologica, have provided evidence for the beneficial therapeutic effects of low glycaemic load diets in acne. Epidemiological evidence confirms that milk consumption has an acne-promoting or acne-aggravating effect. Recent progress in understanding the nutrient-sensitive kinase mammalian target of rapamycin complex 1 (mTORC1) allows a new view of nutrient signalling in acne by both high glycaemic load and increased insulin-, IGF-1-, and leucine signalling due to milk protein consumption. Acne should be regarded as an mTORC1-driven disease of civilization, like obesity, type 2 diabetes and cancer induced by Western diet. Early dietary counselling of teenage acne patients is thus a great opportunity for dermatology, which will not only help to improve acne but may reduce the long-term adverse effects of Western diet on more serious mTORC1-driven diseases of civilization.

Dietary exposure to fumonisins and evaluation of nutrient intake in a group of adult celiac patients on a gluten-free diet.

Abstract Title: Dietary exposure to fumonisins and evaluation of nutrient intake in a group of adult celiac patients on a gluten-free diet. Abstract Source: Mol Nutr Food Res. 2012 Apr ;56(4):632-40. PMID: 22495987 Abstract Author(s): Chiara Dall'asta, Alessia Pia Scarlato, Gianni Galaverna, Furio Brighenti, Nicoletta Pellegrini Article Affiliation: Department of Organic and Industrial Chemistry, University of Parma, Parma, Italy. Abstract: SCOPE: The main objectives of this study were to estimate dietary fumonisin exposure and nutrient intake in a group of patients diagnosed with celiac disease compared to non-celiac subjects. METHODS AND RESULTS: The fumonisin level in 118 frequently consumed corn-based products was determined and dietary habits were recorded using a 7-day weighed food record. Data were then compared to those obtained for a control group. The fumonisin intake in the celiac patients was significantly higher than in controls, with mean values (± SE) of 0.395 ± 0.049 and 0.029 ± 0.006 μg/kg body weight per day, respectively. With regard to nutritional habits, celiac patients showed a preference for a high fat diet, coupled with a high intake of sweets and soft drinks and a low intake of vegetables, iron, calcium and folate. CONCLUSION: These findings may have serious health implications for the celiac population due to the widespread occurrence of fumonisins in most of the widely consumed gluten-free products, leading to continuous exposure to this particular mycotoxin. Moreover, the recorded nutritional quality of the celiac patient's diet raises concerns regarding its long-term adequacy and its potential impact on chronic conditions such as type 2 diabetes and cardiovascular diseases.

Evaluation of biological and clinical potential of paleolithic diet. 📎

Abstract: Accumulating evidences suggest that foods that were regularly consumed during the human primates and evolution, in particular during the Paleolithic era (2.6-0.01 x 10(6) years ago), may be optimal for the prevention and treatment of some chronic diseases. It has been postulated that fundamental changes in the diet and other lifestyle conditions that occurred after the Neolithic Revolution, and more recently with the beginning of the Industrial Revolution are too recent taking into account the evolutionary time scale for the human genome to have completely adjust. In contemporary Western populations at least 70% of daily energy intake is provided by foods that were rarely or never consumed by Paleolithic hunter-gatherers, including grains, dairy products as well as refined sugars and highly processed fats. Additionally, compared with Western diets, Paleolithic diets, based on recently published estimates of macronutrient and fatty acid intakes from an East African Paleolithic diet, contained more proteins and long-chain polyunsaturated fatty acids, and less linoleic acid. Observational studies of hunter-gatherers and other non-western populations lend support to the notion that a Paleolithic type diet may reduce the risk of cardiovascular disease, metabolic syndrome, type 2 diabetes, cancer, acne vulgaris and myopia. Moreover, preliminary intervention studies using contemporary diet based on Paleolithic food groups (meat, fish, shellfish, fresh fruits and vegetables, roots, tubers, eggs, and nuts), revealed promising results including favorable changes in risk factors, such as weight, waist circumference, C-reactive protein, glycated haemoglobin (HbAlc), blood pressure, glucose tolerance, insulin secretion, insulin sensitivity and lipid profiles. Low calcium intake, which is often considered as a potential disadvantage of the Paleolithic diet model, should be weighed against the low content of phytates and the low content of sodium chloride, as well as the high amount of net base yielding vegetables and fruits. Increasing number of evidences supports the view that intake of high glycemic foods and insulinotropic dairy products is involved in the pathogenesis and progression of acne vulgaris in Western countries. In this context, diets that mimic the nutritional characteristics of diets found in hunter-gatherers and other non-western populations may have therapeutic value in treating acne vulgaris. Additionally, more studies is needed to determine the impact of gliadin, specific lectins and saponins on intestinal permeability and the pathogenesis of autoimmune diseases.

High amylase resistant starch to decrease stool output in people with short bowel syndrome: A pilot trial.

Related Articles High amylase resistant starch to decrease stool output in people with short bowel syndrome: A pilot trial. Clin Nutr ESPEN. 2019 Feb;29:242-244 Authors: Hamilton K, Crowe T, Testro A Abstract Short bowel syndrome (SBS) is defined as having less than 200 cm of functional small bowel. Malabsorptive diarrhoea and dehydration are difficult to manage despite medical therapy and dietary manipulations. Evidence shows that supplementing the diet with High Amylase Resistant Starch (HARS) can reduce diarrhoea from a number of causes including gastroenteritis. It is hypothesised HARS will decrease stool output via the production of short chain fatty acids and the resultant increased water reabsorption. This study aimed to determine if the addition of HARS can reduce diarrhoea in patients with SBS. METHODS: Patients with SBS with colon in continuity were recruited from the intestinal rehabilitation clinic at Austin Health. The study was a 2 week crossover trial. Each participant completed the control and the intervention (addition of 50 g HARS to usual diet). Total daily stool weight and number of bowel actions per day were compared between groups using paired t-tests. RESULTS: Eight adults (58% male, mean age 55.7 yrs) were recruited. Five participants completed the trial. Total daily stool weight was reduced in all participants when consuming HARS. Mean daily stool output was significantly decreased 1049 ± 519 g/d to 804 ± 585 g/d (p = 0.023). Number of bowel actions per day showed a trend to reduction. CONCLUSION: This study gives some support to the hypothesis that the addition of HARS into the diet of patients with short bowel syndrome reduces stool output. Longer trials are required to confirm the effect on nutritional/hydration status. PMID: 30661694 [PubMed - in process]

Acting on non-communicable diseases in low- and middle-income tropical countries.

Related Articles Acting on non-communicable diseases in low- and middle-income tropical countries. Nature. 2018 07;559(7715):507-516 Authors: Ezzati M, Pearson-Stuttard J, Bennett JE, Mathers CD Abstract The classical portrayal of poor health in tropical countries is one of infections and parasites, contrasting with wealthy Western countries, where unhealthy diet and behaviours cause non-communicable diseases (NCDs) such as heart disease and cancer. Using international mortality data, we show that most NCDs cause more deaths at every age in low- and middle-income tropical countries than in high-income Western countries. Causes of NCDs in low- and middle-income countries include poor nutrition and living environment, infections, insufficient taxation and regulation of tobacco and alcohol, and under-resourced and inaccessible healthcare. We identify a comprehensive set of actions across health, social, economic and environmental sectors that could confront NCDs in low- and middle-income tropical countries and reduce global health inequalities.

Adherence to the Mediterranean diet and IVF success rate among non-obese women attempting fertility.

Related Articles Adherence to the Mediterranean diet and IVF success rate among non-obese women attempting fertility. Hum Reprod. 2018 03 01;33(3):494-502 Authors: Karayiannis D, Kontogianni MD, Mendorou C, Mastrominas M, Yiannakouris N Abstract STUDY QUESTION: Is adherence to the Mediterranean diet (MedDiet) associated with better IVF performance in women attempting fertility? SUMMARY ANSWER: Greater adherence to the MedDiet, defined using the validated Mediterranean diet score (MedDietScore), was associated with a higher likelihood of achieving clinical pregnancy and live birth among non-obese women <35 years of age. WHAT IS KNOWN ALREADY: Diet impacts fertility and certain nutrients and food groups appear to have a greater effect on reproductive health, but there are relatively few published data on the role of dietary patterns, and the MedDiet in particular, on assisted reproductive performance. STUDY DESIGN, SIZE, DURATION: This prospective cohort study included 244 non-obese women (22-41 years of age; BMI < 30 kg/m2) who underwent a first IVF treatment in an Assisted Conception Unit in Athens, Greece, between November 2013 and September 2016. The study was designed to evaluate the influence of habitual dietary intake and lifestyle on fertility outcomes. PARTICIPANTS/MATERIALS, SETTING, METHODS: Diet was assessed before the IVF treatment via a validated food-frequency questionnaire. Adherence to the MedDiet was assessed through the MedDietScore (range: 0-55), with higher scores indicating greater adherence. Intermediate outcomes (oocyte yield, fertilization rate and embryo quality measures) and clinical endpoints (implantation, clinical pregnancy and live birth) were abstracted from electronic medical records. Associations between MedDietScore and IVF outcomes were analysed using generalized linear models adjusting for age, ovarian stimulation protocol, BMI, physical activity, anxiety levels, infertility diagnosis, caloric intake and supplements use. MAIN RESULTS AND THE ROLE OF CHANCE: No association of MedDietScore with any of the intermediate outcomes or with implantation was found. However, compared with women in the highest tertile of the MedDietScore (≥36, n = 86), women in the lowest tertile (≤30, n = 79) had significantly lower rates of clinical pregnancy (29.1 vs 50.0%, P = 0.01) and live birth (26.6 vs 48.8%, P = 0.01). The multivariable-adjusted relative risk (95% CI) for clinical pregnancy comparing women in the lowest with women in the highest tertile of the MedDietScore was 0.35 (0.16-0.78; P-trend=0.01), and for live birth it was 0.32 (0.14-0.71; P-trend = 0.01). These associations were significantly modified by women's age (P-interaction <0.01 for both outcomes). MedDietScore was positively related to clinical pregnancy and live birth among women <35 years old (P ≤ 0.01) but not among women ≥35 years. Among women <35 years, a beneficial 5-point increase in the MedDietScore was associated with ~2.7 times higher likelihood of achieving clinical pregnancy and live birth. LIMITATIONS, REASONS FOR CAUTION: Our finding cannot be generalized to the whole reproductive population nor to obese women nor to women attending infertility clinics around the world. In addition, due to the observational study design, causal inference is limited. WIDER IMPLICATIONS OF THE FINDINGS: The results suggest that diet modifications and greater compliance to the Mediterranean diet may help increase the chances of a successful pregnancy and delivering a live baby for women undergoing IVF treatment.
