Nutrition of Taro

Nutrition not only encompasses the vitamins and minerals of taro, but the culture of it as well. Culture is part of the wellbeing and this wellbeing can be considered, as transferable to nutrition. A stressed plant isn't particularly attractive to nutrition in any shape or form. So well cover both aspects here... Probably the best intro is the intro on the Recipes, just to get you in the Picture.

An Excerpt from the Ethnobotanical Leaflets, by Wilfred Lee, 1999

"Within the last sixty years, investigators have confirmed the superiority of taro over other starchy staples. The digestibility of taro starch has been estimated to be 98.8 percent. The size of the taro starch grain is one-tenth that of potato. Because of its ease of assimilation, taro can be used by person with digestive problems. Taro flour and other products have been used extensively for infant formulae in the United States and have formed an important constituent of proprietary canned baby foods. Taro is especially useful to persons allergic to cereals and can be consumed by children who are sensitive to milk. Poi can be used as a carbohydrate base to formulate milk substitutes. Sensitivity to taro occurs far less frequently than it does to other starches.

In an intensive survey of tooth decay among the Melanesian inhabitants of the Manus Islands, a comparison was made between people who ate only taro and those subsisting on sago (Metroxylon sp.). Those eating taro had better dental arches and showed a lower incidence of acute or subacute infection of the gums. This was ascribed to the higher vitamin content of taro. Similarly, a marked improvement in dental conditions and a reduced incidence of pneumonia, diarrhea, enteritis, and beriberi resulted among babies born on Hawaiian plantations who were fed poi and sweet potato in place of bread and rice.

In many ways taro is a unique crop. Its starch granules vary in size from 1 to 6.5 micrometers and it can be useful as an additive to render plastics biodegradable.....

.....With the introduction of cash crops there is a tendency for the farmers to neglect subsistence gardens and to use the money earned to purchase store food. This trend can introduce serious nutritional problems among people whose primary diet is taro-based.

The policies of governments in developing nations are usually centered around reducing imports, increasing exports, and raising the standard of living and nutritional levels of the population. In most countries these policies have led to crop improvement programs centered on local staple crops. For the most part these have been grains such as wheat, corn, and rice. Root crops in general and taro in particular have been neglected because only 10 percent of the world population is using root crops as a major staple. The time has come, however, to increase the world production and utilization of root crops. "

Taro as the foundation of Pacific food security

Healthy eating

"...Taro has been reaffirmed as a healthy component of Pacific diets by nutritionists and health specialists (see Malolo et al. 1999). Its starch granules are smaller than other starches and thus more readily absorbed by the young, the elderly, and those with stomach illnesses. It has a beneficially low value on the glycaemic index (1999:25). It is high in fibre, contains a fair amount of protein and other valuable micro-nutrients. From a Pacific perspective it is healthy because it makes the eater feel full and satisfied (Leota in Pollock and Dixon, 1995).

For one hundred years (1860s through l960s) regrettably Europeans derided taro as a primitive food that should be replaced by bread and potatoes. Those early Europeans were unfamiliar with the root and tree crops found in the Pacific so considered them part of the “uncivilized culture”. That the root crops grew easily, and thus did not necessitate “hard work” to maintain the crop also added to this image. Early European settlers pushed their own foods, namely bread and potatoes, as the “good foods” that should replace taro etc. Though they were not successful in banishing taro from the diet they left a legacy that taro was inferior as a foodstuff (and likewise the stigma of agricultural labour) (Pollock 1989 for Fiji).

The traditional diet of many Pacific island households relied heavily on the starchy component, such as taro, yams,breadfruit etc. One or two of these formed some 80% of daily intake, with the balance provided by fish, or coconut, or other addition. (This emphasis was and still remains the basis of diets throughout South East Asia. ) Taro is kakana dina – the real food. Eaten together with an accompaniment (I coi), it becomes a meal. Alone it is just a snack. Taro is thusa means of satisfying hunger both physically and mentally. Taro is good food, real food.

Taro leaves, especially the young ones, are a highly valued accompaniment, particularly in Samoa and Tonga. Mixed with coconut cream, or wrapped around some corned beef, they provide both additional nutrients, as well as a strong identity as a Pacific island foodstuff. Palusami as the latter dish is known in Samoa, has increased its value particularly for overseas Samoans, who regard it as a “traditional” dish associated with the homeland (see Appendix for a song reflecting this euphoric value). The availability of taro leaves to wrap foods is also a sign of good husbandry, that the people are using their land to provide for everyone’s needs, the household and the extended family. In this sense the whole taro plant, leaves and corm, is a representation of social relationships, from gift giving to community support.

Conclusions

Taro is a sad example of the implications of the loss of bio-diversity. As a locally grown foodstuff it has the potential to supplement other foods in daily household use. But it needs support from many sectors, both government and private to ensure a ready supply is available at reasonable cost. The taste for it is still there.

The store of local knowledge which supported such a diverse range of tastes of this root, and the agronomic techniques that enabled its provisioning is diminishing rapidly. Growing taro for subsistence or cash is vital to the future security of food supply. It will continue to be eaten alongside rice, but if a household can dig up two or three taro corms for the evening meal, she will save her cash for other expenditures, and the rice will remain for another day.

A healthy lifestyle includes both enjoying the taro produced in the home gardens, as well as the work in planting, weeding and harvesting it. And sharing the delicious food with other members of the community and beyond also gives “added value”.

Restoring the value of taro by maintaining its diversity, supporting local knowledge of its place in culture, including production techniques, will increase the placement of taro at the centre of a healthy lifestyle. With households empowered through their taro culture, we have a firm base for moving towards increasing food security. That old time security can be recaptured to take a new place within the ways of living of the twenty first century...."
