Everything you need to know about
Tomatoes
Juicy and sweet, fresh tomatoes are a
delicious addition to salads, while the canned variety can be used to make
delicious sauces for pasta dishes, stews and curries. But did you know that
tomatoes also pack a whole host of health benefits too?
Although
often treated as a vegetable in cooking, the tomato is actually a fruit that
belongs to the nightshade family, along with aubergines, peppers and potatoes.
They come in a range of sizes and varieties from small cherry to big beef, and
traditionally they're red in colour, but you can also get tomatoes in yellow,
green, purple and orange.
What is the nutritional
profile of tomatoes?
Tomatoes are
mainly a carbohydrate with some fibre, but they are best known for their
vitamin content which includes beta-carotene (which becomes vitamin A when
consumed), vitamins C and E, some B vitamins and vitamin K. They also
contribute some minerals including calcium and magnesium.
Are tomatoes good for
heart health?
A hundred grams of tomatoes would
provide about 6% of the Nutrient Reference Values (NRV) of potassium for
adults. There is evidence that higher dietary potassium intake is associated
with lower rates of stroke and may be associated with lower rates of heart
disease.
Tomatoes
contain a compound called lycopene, which gives them their red colour, and
there is growing research into its properties and potential for reducing the
risk of cardiovascular disease.
Are tomatoes good for
your eyes?
Tomatoes
contain a group of Phytochemicals called carotenoids, including Lycopene,
Lutein and beta-carotene. These compounds are important to maintain eye health
and may protect against age-related macular degeneration and other eye
diseases.
Are tomatoes good for
your skin?
The carotenoids
found in plants, including tomatoes, may help prevent UV damage in humans. A
2006 study found that after a 10-12 week study there did appear to be a
decrease in sensitivity as a result of increasing dietary carotenoids. However,
this is not to say that you won't burn if you eat lots of tomatoes – it's still
important to follow guidelines and be careful in the sun to avoid UV damage.
Can tomatoes help with blood clotting
and wound healing?
Tomatoes are
a good source of vitamin K which is necessary for blood clotting and wound
healing, with 100g of tomatoes containing 6 mcg of vitamin K. There is also
increasing evidence that vitamin K may be of benefit in bone and cardiovascular
health too.
Can tomatoes help
reduce menopausal symptoms?
A 2015 study
by the Nutrition Journal found that tomato juice intake did help alleviate some
menopausal symptoms such as anxiety, resting energy expenditure and heart rate.
This study was carried out on 95 women aged 40-60 years old and they had to
consume 200ml of unsalted tomato juice, twice daily, for eight weeks. While
this was a small trial, the results are encouraging and warrant further
research into this area.
Is it better to cook tomatoes or eat
them raw?
Research
suggests that processing and cooking tomatoes can increase their nutritional
value, in particular, their antioxidant activity and lycopene compounds.
Cooking the
tomatoes as well as serving them with a tad of oil has shown to enhance the
body’s absorption of this photochemical. Grill tomato halves with a slight
coating of olive oil and top with chopped fresh basil. It's a wonderful side
and delicious way to enjoy lycopene
