Not on your life.
A population based, mixed population cohort study on kids who were macrobiotic vs. omnivorous showed that macrobiotic fed children suffered form many deficiencies and their growth was retarded from 6-18 months.
If you're considering having a child and feeding the child a vegan/macrobiotic diet, you might want to think again. And if it is so devastating to children, why would it be healthful for an adult? The answer is its not a healthful diet for anyone.
What does macrobiotic even mean? Well, the prefix macro stands for "large" or "long" and bios for "life." So what macrobiotic stands for is "long life." But a diet that is severely deficient in many of the essential micronutrients like vitamin D, B12, riboflavin, calcium, etc. as well as deficient in the macronutrients protein and fat can hardly be considered a diet that is conducive to a long life. Quite the contrary. A macrobiotic diet is in fact completely incongruous to a long human life. Better to call it the Bunny Rabbit Diet.
And yes, eating foods that are less processed is a good thing. And this is why some people who adopt a macrobiotic diet become healthier in the short run. They quit eating garbage and opt instead for more natural foods. But to shun all meat and only eat fish sparingly grossly undermines human health. All humans that is.
Food for thought.
