The Macrobiotic Diet

Overview

The main foods in a macrobiotic diet are whole grains, locally grown fresh veggies, sea veggies, and beans. You can also eat seasonal fruits, nuts, seeds, and white fish two to three times per week. You don't eat meat, dairy, and most other animal products, certain fruits and veggies, and some common drinks.
The diet became popular in the 1970s. The term “macrobiotics” refers to a holistic lifestyle of eating and living in harmony with nature to promote a long, healthy life.

How This May Work

The idea behind this diet is that a modern, western diet is the cause of many illnesses, such as cancer. People on the diet believe that eating a mainly vegetarian diet with unprocessed, whole foods from where you live will lead to better health and happiness.

What’s Involved?

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 amounts you eat look like this:
  • 50%-60% whole grains
  • 25%-30% veggies
  • 5%-10% soups
  • 5%-10% beans and sea veggies

Other Parts of the Diet

  • Whenever you can, choose organic foods.
  • Vitamin and mineral supplements are not advised.
  • 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, the part of your body that is affected will also influence your diet.
  • Macrobiotics is a type of holistic lifestyle. Diet is one part of this lifestyle.

What Does the Research Say?

Some people who use this diet claim that it can help prevent and cure cancer. There is no evidence that suggests that. Its role in cancer prevention is being studied.
Many studies have shown that a strict macrobiotic diet can result in nutritional deficiencies, especially among children. One study showed that teens who were fed a strict macrobiotic diet in early childhood had lower bone mineral density than those who were not. Another study found that infants and toddlers on the diet had several nutrient deficiencies resulting in delayed growth, fat and muscle wasting, and slower psychomotor development.

Are There Any Concerns?

While some people may be able to meet their nutrient needs on a this diet, it can be hard to do. There are many health and nutrition concerns, such as not getting enough protein, vitamin B12, and calcium. There is also the chance you becomedehydrated. Another concern is stress—for both the dieter and their families—from trying to follow the plan.

Bottom Line

Parts of the diet are healthful, such as the focus on whole grains, veggies, and beans, and not eating refined and processed foods. However, overall this diet is too strict and limits many healthful foods. If you choose to follow this diet, think about relaxing some of the guidelines to allow for a more well-balanced diet. A strict macrobiotic diet should not be followed by infants, children, or women who are pregnant or breastfeeding.
