The Macrobiotic Diet

What is the Macrobiotic Diet?

The main foods in a macrobiotic diet are whole grains, local fresh veggies, sea veggies, and beans. Other foods include seasonal fruits, nuts, seeds, and white fish two to three times per week. You cannot eat meat, dairy, most other animal products, certain fruits and veggies, and some common drinks.

The diet became popular in the 1970s. The term “macrobiotics” refers to eating and living in harmony with nature. The goal is to promote a long, healthy life.

How The Macrobiotic Diet May Work

The idea behind this diet is that a modern, western diet causes many illnesses, such as cancer. People on the diet believe that the key to health is eating a mainly vegetarian diet with unprocessed, whole foods from where you live.

Macrobiotic Diet Basics

The main foods on this diet are whole grains and grain products, veggies, sea veggies, and beans. Other foods are fish and seafood, fruits, drinks, and snack foods. The diet is:

  • 50% to 60% whole grains
  • 25% to 30% veggies
  • 5% to 10% soups
  • 5% to 10% beans and sea veggies

Other Parts of the Diet

  • Choose organic foods when you are able.
  • Do not take vitamin and mineral supplements.
  • Meals need to be made using certain cooking methods. Using microwaves or electricity to cook is discouraged.
  • Some of the foods you can eat will depend on where you live.
  • If you have cancer, you will eat certain foods. It depends on the part of your body that is affected.
  • Macrobiotics is a lifestyle. Diet is one part of this lifestyle.

What the Research Says

Some people claim this diet helps prevent and cure cancer. There is no evidence that suggests that.

Many studies have shown that a strict macrobiotic diet can result in poor nutrition. Children on the diet may be at risk for weaker bones. Infants and toddlers on the diet could be at risk for delayed growth and motor skills.

Concerns

Some people may meet their nutrient needs on this diet. However, it can be hard to do. Some problems may be not getting enough protein, vitamin B12, and calcium. There is a risk of dehydration. Another concern is stress from trying to follow the plan.

Conclusions

Parts of the diet are healthful. This includes eating whole grains, veggies, and beans, and not eating processed foods. Overall, this diet is too strict and limits many healthful foods. If you choose to follow this diet, think about not being so strict. A strict macrobiotic diet should not be followed by infants, children, or women who are pregnant or breastfeeding.
