Can I put natto on my purple potatoes?

Quick answers

Red meat?Limit

Not on a regular basis.

Keto?No

No, not in the traditional sense. Okinawans are not a good candidate for keto diets, even plant based keto diets that rely heavily on monounsaturated fats like olive oil.

Carnivore?No

Nope.

Fermented foods?Yes

Natto, a fermented Japanese soybean, is a staple of Okinawan cuisine, and if our Okinawans can stomach the odor and flavor, we say go for it! Really, all fermented foods can be on the menu for Okinawans, other than fermented dairy which is likely to cause digestive problems.

Pancakes and refined grains?No

The metabolic muscle for Okinawans is in their ability to deal well with complex carbohydrates. In theory, this means they should be able to include some processed carbohydrates in their diet as well. However, no diet type will do well eating pretzels at every meal. Instead, Okinawans who have ruled out celiac and gluten sensitivity may be able to include some locally baked sourdough bread as part of their eating plan.

Biggest challenge

Making a plant based diet work for each individual Okinawan. The fat and carbohydrate metabolism scores indicate that Okinawans are best suited to a largely plant based diet. This means at least 5 days per week of vegetarian eating. However, the key for each Okinawan is to determine just how plant based they need to go for optimal health. In some cases, as when heart disease has already reared its head, this may mean a strict vegan diet. However, other Okinawans will find benefit from the addition of some fish and eggs a couple days a week.

Closest relative

Not quite you? The nearest type is Vegetarian. Both the Vegetarian and Okinawan diet types are plant based (but not plant exclusive) and both deal well with a diet rich in complex carbohydrates like the purple yams from Frieda’s. The main difference between these two diets is dairy and histamine. Okinawans are able to deal well with histamine, but are very likely to be lactose intolerant, so dairy is off the menu.
