First, let's take a look at the macros. Each of these are listed in grams and as usual, normalized to 200 calories for easy comparison, so we're always comparing apples to apples.
Next, let's take a look at the Vitamin density. These values are shown in units of percent of recommended daily intake. And since we're showing 200 calories worth, this means anything above 10% is good.
Spinach have significantly more Vitamins A, E, K than purslane. Purslane have significantly more Vitamins C than spinach. Spinach are a great source of Thiamin, Niacin, Zinc, Phosphorus. Spinach are an excellent source of Vitamin A, Vitamin E, Vitamin K, Vitamin C, Riboflavin, Vitamin B6, Potassium, Magnesium, Calcium, Iron. Purslane are a good source of Zinc. Purslane are a great source of Thiamin, Niacin, Vitamin B6, Phosphorus. Purslane are an excellent source of Vitamin A, Vitamin C, Riboflavin, Potassium, Magnesium, Calcium, Iron.
And here we see the B-vitamins: B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine)
Now, lets look at mineral density. Here we have a lot of important electrolytes and minerals. Once again, units are in percent of RDI, thus for this 200 calorie serving anything above 10% would considered high.
