Nutritious Pacific plants

The green leaves of plants are important foods in almost all parts of the world. Scientists believe that about 1000 different plants have leaves that can be eaten. Many of these plants grow in the Pacific Islands. A few can be found or grown on dry coral atolls.

Some kinds of green leaves grow on trees or bushes, and others on smaller, leafy plants. Trees and bushes produce leaves for a long time, provide leaves even during the dry season, need very little care, and can be used to fence gardens. Cabbages, spinach-like green leaves, and other small leafy plants produce more leaves in a shorter time and are easier to pick than trees or bushes.

Trees, bushes and small leafy plants are all good crops for a home garden. Growing green leaves in a home garden is a good way to make sure fresh green leaves are always available for family meals.

Sometimes green leaves can also be found in the bush or growing as weeds in gardens or farm-land. Gathering and preparing traditional leaves is a low-cost way to enjoy the taste and goodness of green leaves.

Quality foods for everyone

Many popular plants that are grown for other purposes have leaves that can be eaten, for example, taro sweet potato, cassava, pumpkin and chilli. Often, the leaves have a greater food value than the main crop. However, if too many leaves are picked from one plant, the main crop may not grow properly. Sometimes it is best to keep two plots one for leaves and one for the other crop.

The market is another place to find green leaves, especially for people who live in towns. The traditional green leaves that can be bought at the market are usually a better buy than European lettuce and cabbage. An advantage of growing your own green leaves is that you know they are fresh and have no pesticide on them.

In some places in the Pacific, green leaves are eaten often, whereas in other places, they are regarded as 'poor man's food' or animal food. This is not true. Green leaves are one of the most healthy foods found in the Pacific. Where possible, everyone should learn to grow or buy whatever kinds of leaves can be eaten.

Dark green leaves are one of the most nutritious foods available. Some foods have only a few of the nutrients the body needs, but green leaves have many important vitamins and minerals. Therefore, serving lots of green leaves can help make sure family meals are well balanced.

Plants make and store protein, which the body needs to grow and stay healthy. Meals that do not include other protein sources such as meat, fish eggs or beans should always include lots of dark green leaves.

Eating green leaves gives people important minerals, such as iron which makes blood strong, calcium which is necessary for healthy bones, magnesium and potassium which are needed to help bodily functions during heavy work or when playing sports in hot climates.

Green leaves are also a source of vitamins, including Vitamin A, Vitamin B and Vitamin C. Vitamins are necessary for good health. They help the body work properly.

Almost all green leaves are a good source of some protein, vitamins and minerals, but darker green leaves usually have more nutrients than lighter green leaves.

Green leaves also provide a good source of dietary fibre. Fibre prevents constipation and helps the body to have regular bowel motions. It also tends to lower blood cholesterol and help prevent heart disease.

Green leaves for special needs

Everyone in the family should eat some green leaves every day. In particular, children, pregnant women and nursing mothers need the protein, vitamins and minerals found in green leaves. If these groups of people do not get enough iron, they are likely to get anaemia, which means they do not have enough red cells in their blood. This condition makes women feel tired and weak and children do poorly in school and sports. Anaemia can be prevented by eating lots of green leaves.

People with special needs should eat each day the amounts of cooked green leaves listed below:

Babies, 4 - 6 mths to 2 years:

1 - 2 tablespoons

2 years - 5 years:

¼ cup

School children:

½ cup

Pregnant women:

¼ cup

Nursing mothers:

½ cup

For babies, soft leaves with no stems are best. Some good leaves for babies are: basella, edible hibiscus ferns and tropical spinach.

Since babies cannot chew well, the leaves can be mashed, strained or ground, and given by spoon to the baby. Adding a small amount of green leaves to other soft foods prepared for babies is also a good idea.

Plain or fancy preparation?

Green leaves are usually at their best during the hot, wet months. When leaves are picked from the plant during this time, new ones will grow back quickly.

The leaves chosen for eating should be young and soft. The crisp tops and side shoots of some plants can be used. Older leaves are sometimes tough, have a stronger flavour and need to be cooked longer.

Some green leaves, such as watercress, kangkong, basella, Chinese cabbage and European cabbage, can be eaten raw in salads. Raw salads are a healthy way to use green leaves since no vitamins or minerals are lost in cooking. This also saves cooking fuel.

If green leaves are to be eaten uncooked, they must first be washed thoroughly so that they do not cause sickness. Soaking leaves in the sink or a bowl of clean water for a few minutes is also a good idea. They should be gently dried with a cloth or shaken dry before use.

Some other green leaves can be cooked, left to cool, then used for salad. Athyrium ferns and pumpkin shoots are good this way.

Salads do not have to be prepared strictly according to recipes. Any available vegetables or other foods can be used. They taste best with a little lemon juice and oil mixed together, or salad dressing.

Green leaves should never be cooked longer than necessary. They should be eaten straight after cooking. Some good methods for cooking leaves are given here.

Easy method for most green leaves

1. Wash leaves in clean water and remove tough stems.

2. Put a small amount of water in a cooking pot, and bring to the boil.

3. Add the leaves, cover with a lid, and cook until tender but still crisp (3 - 10 minutes).

4. Add coconut cream a few minutes before the leaves are cooked, or serve with coconut cream, if desired.

5. If making a soup or a sauce, use leftover cooking water (but when cooking cassava leaves, throw away the water and use thin coconut cream instead).

Special method for leaves that are very bitter or that cause the mouth to itch or burn, such as taro leaves or cassava leaves

1. Wash leaves and place in a pot with enough water to cover.

2. Bring to the boil and boil 5 -10 minutes with lid off.

3. Drain the water off and throw it away.

4. Add enough fresh water or coconut cream to cover the leaves again, add a little salt, put a lid on, and steam until tender (15-20 minutes).

Stir frying

1. Cut up leaves. Heat a little oil or fat in a pot (1 teaspoon for every cup of leaves).

2. Add chopped garlic, ginger or other flavourings, and fry for 1 minute.

3. Stir in cut-up leaves and fry, stirring all the time, for about 5 minutes.

4. Add a few teaspoons of water if necessary, cover the pot, and steam for 2 - 5 minutes. Serve hot.

Note: Coconut cream can be added to the green leaves for extra flavour and food value.

Cooking green leaves with coconut cream, a little oil, or other body-building foods such as meat, fish (especially fatty fish) and chicken helps the body use the Vitamin A that is in the leaves. Green salads mixed with shellfish legumes (beans and peas) and a little dressing are very easy and nutritious ways to eat green leaves.

Green leaves can also be added to any kind of soup or stew to add flavour and nutritional value, or simply cooked with meat or fish as a main dish for the family.
