A medium sized family farm in Georgia presses their own small batch oils, including Okra Seed Oil (along with pumpkin seed, Sunflower seed, and various nut oils and olive oil mixes).
The primary reasons seed based oils are not well received is in the heat and time point between cooking (especially sauteing) and burning.
All that being said-
What is called a Mediterranean or East Asian type diet with moderate portion sizes has been shown to be healthy and recommended for almost two centuries now for the average person in the Northern Hemisphere: low starches, moderate fatty foods, whole grains as a "carb base" for the meal. Meals should consist of whole "fruits and veggies" and animal (including dairy and eggs) servings on about a 1 to 1 mix, with moderate amounts of sugars.
And, of course, vinegars, herbs and spices (don't forget those) as healthful digestive and metabolism supplements.
Proteins can be supplied with plant protein, but the lipids are not the same, and while good half of people in the Northern Hemisphere can easily live on on plant proteins, some people still need meat based proteins.
Also, extremely heavy labor or extreme environmental situations (especially extreme cold) where the body might require more fat and animal proteins for the energy to "keep going" might change a ratio of animal based fats to plant based fats needed, but nutrient requirement is still pretty much the same to maintain human health.
But with even a basic understanding of biology, when looking at the industrialized "diet plan" that has been pushed over the last century or so, public nutrition seems to be based on "class" and the amount of profit in the supply chain. The industry wasn't so much concerned about overall health benefits and varieties, it's designed to facilitate sales of high profit commercially grown or manufactured products as "just as healthy" as lower profit, regional food products that aren't mass produced and profitable.
Your milage on nutrition may vary, of course, but then, that's between you, your phlebotomist, and your doctor.
