The Tukisenta Tribe: A Nutritional Paradox in the Highlands of Papua New Guinea

The Tukisenta tribe, residing in the highlands of Papua New Guinea, presents a fascinating case study in nutrition and health. Despite deriving 90% of their traditional diet from sweet potatoes, the Tukisenta people exhibit none of the chronic diseases that plague modern societies, such as obesity, diabetes, heart disease, or high blood pressure. This fact would not have been surprising because, since the '90s, high carb-low fat diets have been most popularly recommended. However, this intriguing paradox challenges the newly prevailing "low carb" diet trend and raises important questions about the true culprits behind these health issues. In this post, I will cover their diet and a few other “extreme” traditional diets and discuss the real culprits behind the ever-increasing amount of chronic illnesses.

Decoding the Effects of Low-Carbohydrate Diets on Cholesterol in People With Different BMI

On January 17, 2024, a groundbreaking study titled "Increased Low-Density Lipoprotein Cholesterol on a Low-Carbohydrate Diet in Adults with Normal but Not High Body Weight: A Meta-Analysis" was published by Adrian Soto-Mota, Dave Feldman, Nicholas Norwitz, and others. This research provides new insights into the effects of low-carbohydrate diets on cholesterol levels, with a particular focus on low-density lipoprotein cholesterol (LDL-C), commonly known as 'bad' cholesterol. In this blog post, I will explain the study's design and results, which refute the current medical thinking that saturated fat has the most significant effect on raising cholesterol. The authors found that body weight is much more significant than saturated fat. Their findings suggest that we have things backward.

The Carnivore Diet and Vitamin C Deficiency

The carnivore diet is a dietary regimen that restricts food intake to animal products, primarily meat, and animal-derived products, while excluding plant-based foods. Advocates of the carnivore diet (I am one of them) claim that it provides numerous health benefits, such as weight loss, improved mental clarity, and relief from various health conditions. One common concern with diets that exclude plant foods, like the carnivore diet, is the potential risk of vitamin and nutrient deficiencies, including vitamin C. A well-rounded carnivore diet, including fatty meat and organs, should contain all of the nutrients we require. However, it is important to understand why people on a carnivore diet that includes organ meat should not need to worry about their vitamin C status.
