May I know what nutrients are only found in saturated fats? And the specific reason for you to conclude 5-6% or even 10% of saturated fats as too low?
I know our body needs fats to support healthy body function but fats is more than only saturated fats. There are also mono unsaturated fats and polyunsaturated fats.
Can't we have avocado, cold pressed EVOO, nuts and seeds, wild caught fatty fish, greek yogurt as a source of our fats? Why the need to insist on saturated fats?
Greek yogurt is high in saturated fat.
We eat fats for essential fatty acids AND the micronutrients that are fat soluble:
A, D, E, B complex especially B12 (Cobalamin is not found in veggies) and K2.
From bone marrow, you can get compounds that are precursors for building blood cells and bone & joints: iron, collagen. Especially important for aging as collagen synthesis decrease with age.
If you try to eat them all from veggies, it will be difficult as some are not found naturally.
10% saturated fat is very tiny.... did you try to measure it? It's about 22g of saturated fat for a 2000 calorie diet.
That's problem with restricting this much fat is that you also severely restrict all the micronutrients soluble in fat.
The main downside with plants that must not be overlooked: the amount of nutrients actually absorbed, also known as BIOAVAILABILITY. The presence of fibre, cell walls, and the plant natural toxins can inhibit absorption of nutrients.
For example, if you eat fresh green veggies, most of it will pass out GREEN and undigested. You need to break down the cell walls through crushing/blending, steaming or boiling, then the chlorophyll can be broken down by digestive enzymes and then absorbed into the body.
Another example: whole grain rice is not fully absorbed due to phytic acid (phytates) that actually interferes with the body's absorption of minerals, specifically iron, zinc, magnesium, and calcium.
