Smorgasbord Health Column – Food Therapy – Watermelon – A quick way to hydrate by Sally Cronin

As a follow on from the recent series on the Weekly Grocery Shopping List of foods that contain the nutrients the body needs that contain the nutrients the body needs I am going to repeat my series from 2017 on the health benefits of some of our most common foods.

Food therapy is a broad term for the benefits to the body of a healthy, varied and nutritional diet of fresh foods.

Most of us walk through the fresh produce departments of our supermarkets without really paying much attention to the individual fruits and vegetables. This is a great pity because the vast majority of these foods have been cultivated for thousands of years, not only for their nutritional value but also for their medicinal properties. If you eat a healthy diet you are effectively practicing preventative medicine. A robust immune system, not only attacks external opportunistic pathogens, but also works to prevent rogue cells in the body from developing into serious disease.

NOTE – If you are on any prescribed medication do not take yourself off it without consultation with your doctor. If you follow a healthy eating programme and lose weight and are exercising you may not need the same dose and with your doctor’s agreement you may be able to reduce or come off the medication all together.

Watermelon – A quick way to hydrate

Before returning to Ireland four years ago we lived in Spain for 17 years with temperatures in the summer approaching 40 C…over 100 F which meant that keeping hydrated was very important. Particularly as it was a dry heat. Apart from drinking extra water, salads and other water dense foods were important as part of our daily diet.  However, when it was really hot there was nothing like ice-cold watermelon.

It took me a while to get around the pips in watermelon and learn the knack of spitting them out delicately rather than shooting them at the dog by accident. Once you master this quite simple dexterity, you will have access to not only one of the most thirst quenching melons around, but also a storehouse of health benefits.

Watermelons are obviously sweetest during the summer months but we were lucky enough that Spain has summer somewhere within its boundaries all year round and they are just as accessible at Christmas as in August. Here in Ireland we do get them in season although at the moment that may not be the case with closed borders and a focus on homegrown fruit and vegetables.

However, if you are lucky enough to be able to get your hands on some fresh watermelons, please do so.

Watermelons and health claims.

If you are an asthma or arthritis sufferer, eating this fruit year round may help improve the symptoms of your condition. Watermelon also has gained some recognition with regard to other medical problems too such as atherosclerosis, diabetes and colon cancer.

The history of watermelons.

Watermelons first originated south of us in Africa and were first used medicinally by the Egyptians but obviously the fruit was most prized for its water content in countries where rain was in short supply. Watermelons are now found in Asia, particularly in China and also in Russia where the fruit is a major crop for export. The United States is a major grower but you will find it growing in many desert countries or islands that have water shortages such as Iran and Turkey.

The health benefits of watermelon

Apart from being a wonderful fruit packed with vitamin C, watermelon has something in common with the tomato and that is it’s very high concentration of Lycopene.

Lycopene not only gives fruit that vibrant red colour but it also acts as an incredibly powerful antioxidant. Antioxidants protect us against the free radicals that cause oxidative damage to our cells, often resulting in serious illness such as cancer. It would also seem that healthy levels of lycopene in our fat tissues are also associated with reduced risk of heart attacks. This is due to the prevention of oxidation of cholesterol that so often leads to atherosclerosis and heart attacks.

Vitamin C and Vitamin A work on free radicals as well and are particularly linked to those that cause an increase in the severity of certain inflammatory diseases such as asthma and arthritis.

Vitamin A is essential for our healthy eyesight, especially at night. It helps cells produce normally which is why it is important in the first few months of pregnancy. It is also necessary for the health of our skin, the mucus membranes in our respiratory system (hence its benefits for asthma sufferers), bones, soft tissues and digestive and urinary tracts.

Other nutrients in watermelon that are beneficial.

Vitamin B1 (Thiamin) is a water- soluble vitamin, which means that it cannot be stored in the body. Any excess is excreted in our urine so it is essential that we obtain sufficient from our diet. Vitamin B1 helps to fuel our bodies by converting blood sugar into energy and also keeps our mucus membranes healthy. It is also needed to work with other B vitamins in maintaining a healthy nervous system

Vitamin B6 (Pyridoxine) is the Master Vitamin for processing Amino Acids – the building blocks of all proteins and some hormones. It assists in the formation of several neurotransmitters and can therefore help regulate mood. It has been shown to help lower homocysteine levels in the blood linked to heart disease, osteoporosis and Alzheimer’s disease. It produces haemoglobin the oxygen carrying pigment in the blood. It helps the release of carbohydrates stored in the liver and muscles for energy. It is involved in the production of antibodies and it helps balance female hormones. It is needed for the production of serotonin along with tryptophan and B12.

Magnesium is an essential mineral needed for bone, protein and fatty acid formation, forming new cells, activating the B vitamins, relaxing muscles, clotting blood and forming ATP the fuel the body runs on. The secretion and action of insulin also needs magnesium. It is needed to balance calcium in the body and too much can result in very low levels of calcium.

Potassium is the main cation (positively charged electrolyte). It reacts with sodium and chloride to maintain a perfect working environment in and around each cell. It allows the transmission of nerve impulses and helps maintain the correct fluid balance in the body. It also regulates levels of acidity and alkalinity in the body. It is also required for carbohydrate and protein metabolism. It is connected to normal heart rhythms.

Buying the best watermelons

There are about 1200 different varieties of watermelon and when you are picking one in the supermarket make sure the melon is symmetrical and firm with no cuts or bruises. The heavier it feels the better, as it is 92% water. If it feels a little light then it may be dry inside. If you are buying cut watermelon make sure the skin is bright red as pink flesh with white pith means it is past its sell by date. Eat within a couple of days. You can store at room temperature but it is best served chilled.

Some of my tried and trusted watermelon recipes over the years.

You can use chopped watermelon in salads and in desserts but I have a couple of recipes that are slightly different.

Watermelon Lemonade. A lovely refreshing drink at any time of day


  • 1 large watermelon seeds removed and cubed
  • I peeled cucumber.
  • 6oz of fresh raspberries
  • 8oz of water
  • 4oz of lemon juice.

Blend all the melon, raspberries and water until smooth. Strain through a sieve into a large jug that will fit in the fridge. Stir in the sugar and the lemon juice and mix well. Put into the fridge for about an hour. You can add more water if needed.

Watermelon and strawberry salsa. Wonderful with chicken dishes.


  • 8oz of cubed watermelon with the seeds removed
  • 6 oz of chopped strawberries
  • 3oz of chopped onion
  • 2 tablespoons of olive oil
  • 1-tablespoon lemon or lime juice
  • ½ teaspoon of honey.

Mix all the ingredients together and put into the fridge to chill for about an hour before serving with your chicken or even pork dish.
