+====== Healthiest Diet ======
+The healthiest diet is one which optimizes the amount of nutrients, and decreases the amount of toxins or [[https://en.wikipedia.org/wiki/Antinutrient |antinutrients]].
+\\
+===== Variation Based on Genetics and Microbiome =====
+The paleolithic diet is by definition the healthiest diet, with the assumption that we evolved along with our diet, thus eating the foods that are most nutritious.  However, we did not stop evolving 10K year ago.  Many of our ancestor's lifestyles have not been that of hunter-gatherers for a long time.  There may be variation in what would be the optimal diet for humans, because there is genetic variation based on culture and individual genomes.  Eskimos, for example, are adapted to eating a high fat diet.  [[https://science.sciencemag.org/content/349/6254/1343 |Greenlandic Inuit show genetic signatures of diet and climate adaptation, Fumagalli et al 20150918]]  Other individual variations in what may be an optimal diet, is based on an individual's microbiome, especially the gut flora, as there is a symbiotic relationship in processing and creating nutrients.
+While there may be variation in optimal diet requirements, this article may seek to start with the average optimal diet and tailor it to suit individual needs.
+\\
+===== Organisms Consume Other Organisms for Nutrition =====
+While organisms can create their own energy through photosynthesis or chemosynthesis (see [[https://en.wikipedia.org/wiki/Primary_nutritional_groups |primary nutritional groups]]), predators survive by consuming other organisms.  Predators in this sense, includes herbivores.  Humans are predators, consuming both vegetation and other predators.
+All life is based on DNA, thus having similar nutritional needs.  Predators obtain their nutrition by consuming other DNA based organisms.
+\\
+===== Optimal Diet For Humans =====
+The optimal diet for humans, is based on the consumption of plants, fruits, and animals.  Refinement from this generalization is on a nutrient by nutrient basis.
+The modern diet has too many empty calories: carbohydrates from processed grains and the starchy parts of plants (parts of plants dedicated to energy storage).  These foods are detrimental in part because consuming them reduces the overall levels of other nutrients consumed.
+Modest research has been done to quantify the optimal levels of amino acids, fatty acids, vitamins, minerals, and fiber.
+Phytonutrients and myconutrients, while not considered essential, have benefits which are not fully understood.  There may be hundreds of thousands of different types.  For the sake of the optimal diet, which ones to take, in what amounts, and on what schedule is poorly understood.
+\\
+==== Cooking Alters Nutrients ====
+Cooking, especially at high temperatures, creates [[https://www.vmi.pitt.edu/EPR-ROS/index.html |reactive oxygen species]] that are carcinogenic, such as [[https://en.wikipedia.org/wiki/Advanced_glycation_end-product |AGES]], [[https://en.wikipedia.org/wiki/Heterocyclic_amine |HCAs]], and [[https://en.wikipedia.org/wiki/Polycyclic_aromatic_hydrocarbon |PAHs]].
+Cooking reduces the nutrition levels of many foods:
+[[https://www.ars.usda.gov/ARSUserFiles/80400525/Data/retn/retn06.pdf |USDA Table of Nutrient Retention Factors, 2007]]
+[[https://www.healthline.com/nutrition/cooking-nutrient-content |How Cooking Affects the Nutrient Content of Foods, healthline.com]]
+[[http://web.archive.org/web/20201030134730if_/https://dlife.com/qa/cooking-vegetables-destroy-fiber-content-value |Does Cooking Vegetables Destroy Or Diminish The Fiber Content Or Value? Franziska Spritzler, RD, CDE 20170413]]
+Cooking also changes the nature of the fiber in cooked vegetables, as it breaks down and shortens fiber molecules.  [[https://pubmed.ncbi.nlm.nih.gov/11030475 |Dietary fiber content of commonly fresh and cooked vegetables consumed in India, Khanum et al 2000]]  There are individual cases where certain nutrients are more accessible in cooked vegetables, such as tomatoes, carrots, spinach, mushrooms, asparagus, cabbage, peppers, green beans, eggplant, brussel sprouts, and kale.
+Ideally, I would know on a case by case basis, or which combinations of raw and cooked foods to eat in a day or week.  But I can venture that cooking foods is not a requirement for nutrition, and uncooked fruits and vegetables delivers the best quality fiber.  I can also venture that low temperature cooking and not overcooking is better.
+\\
+==== Grains and Tubers Are Not Optimal ====
+Grains and tubers are energy storage sources for plant growth.  In animals, fat is used for energy storage.  Grains and tubers are excessively high in carbohydrates compared to other nutrients.
+While some whole grains provide good sources of dietary fiber, there is no reason to consume them.  "Grains are not essential, and there is no nutrient in there that you can’t get from other foods."  [[https://www.healthline.com/nutrition/grains-good-or-bad |Grains: Are They Good For You, or Bad? healthline.com]].  Grains are seeds, and seeds contain reserve energy for the growth of a new plant.

+[[https://sci-hub.ee/10.1016/bs.afnr.2020.06.005 |source]]
+\\
+==== Nutrition Density Score ====
+While ignoring that some nutrients are optimal at a certain dosage, the nutrient density score ranks foods by the ratio of nutrients to the amount of energy a food supplies.
+Note that GMO fruits and vegetables engineered for a larger size will have a lower nutrient density, compounded by the lower nutrient density in overworked, synthetically fertilized soil.

+[[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6489166 |This other related study]] was funded by General Mills, probably in retaliation to the uprising nutrient density research which was threatening to ruin their profit model, so the [[sociology:conflict-of-interest |results are not credible]].
+\\
+==== Insulin Index and Satiety Score ====
+When deciding on inclusion or exclusion of any food, these two metrics are worth looking up.  Note I chose the [[https://optimisingnutrition.com/glycemic-index-load-versus-insulin-load/ |insulin index instead of the glycemic index]].
+https://en.wikipedia.org/wiki/Insulin_index#Explanation_of_Index\\
+{{:health:insulin-index-food-list.png?direct&600|Insulin Index for a List of Foods}}
+[[https://public.tableau.com/app/profile/marty.kendall7139/viz/foodinsulinindexanalysis/FIIallfoods |Source and Interactive Version]]
+Of note is that oats are about the highest in the fullness/satiety index/score.  Steel cut oats,  definitely not instant oats as they are lots more processed.  Rolled oats, soaked for several hours, without cooking, are good as a cereal with plain yogurt and stevia leaf as a sweetener (see [[health:zero-calorie-sweeteners]]).
+Another strange case is that pasta has a [[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5884373 |low insulin score]], even though it is a refined carbohydrate.  But take a look at the [[https://en.wikipedia.org/wiki/Glycemic_load |glycemic load]] of pasta:
+{{:health: glycemic-load.gif?direct&600|Glycemic Load}}
+The reason for the high glycemic load is that a typical serving of pasta is a lot heavier than servings of other foods.  The above chart makes sense to me, since my intuition is that raw unprocessed whole foods are healthier.
+The GI values look different than what I have seen.  How could science mysteriously change from 2002 to present data from current internet sources?  The chart is sourced from the former website of a current university professor, an excellent article itself:

+==== What About Hormones in Meat and Dairy? ====
+[[https://doi.org/10.1111/1365-2656.12095 |The evolution of the nutrient composition of mammalian milks, Skibiel et al 20130729]]\\
+[[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4524299 |Hormones in Dairy Foods and Their Impact on Public Health - A Narrative Review Article, Hassan Malekinejad and Aysa Rezabakhsh 201506]]
+Dairy can cause acne in some individuals.  However, yogurt and cheese does not.  "In this meta-analysis we found a positive relationship between dairy, total milk, whole milk, low-fat and skim milk consumption and acne occurrence. In contrary, no significant association between yogurt/cheese and acne development was observed."  [[https://www.sciencedirect.com/science/article/abs/pii/S0261561418301663 |Dairy intake and acne development: A meta-analysis of observational studies, Aghasi et al 201906]]  However, looking at the chart, the precision of the results is underwhelming:
+{{:health:correlating-acne-with-yogurt-cheese.png?nolink|Correlating Acne with Yogurt and Cheese}}
+If you have the genetic ability to produce lactase, can you permanently become lactose intolerant if you go too long without having dairy?  I haven't found a 100% conclusive answer for this.  I have read that persons losing the ability to produce lactase underwent [[https://theconversation.com/can-changing-the-microbiome-reverse-lactose-intolerance-114412 |trauma to the intestines]] such as antibiotics (an epigenetic phenotype).  Also, I read some literature that those who quit dairy for a long time, were able to reintroduce dairy slowly, but the statement was anecdotal.
+"You can also buy meat that is raised without the use of any hormones. Interestingly, however, the amounts of steroid hormones in untreated and hormone-treated beef are virtually identical. It’s just that the animals that aren’t treated take a bit longer to mature. More to the point, the amount of hormones you ingest when you eat meat is miniscule compared to the hormones produced by your own body."  Coincidentally, fiber reduces circulating estrogen.  [[https://www.quickanddirtytips.com/nutrition-diva |Monica Reinagel, MS, LD/N, CNS]]
+While the commentary of one professional may not be conclusive, it's what I have found for now.
