Watch out for secret salt

Eating healthily isn’t supposed to be difficult, and when you are trying really hard to do the right thing it’s frustrating to find that your ‘healthy option‘has thrown you a curve ball. But that’s what a survey in the news a couple of weeks ago seemed to suggest with its findings showing that some salads were saltier than a burger.

Salt is a tricky one because it’s not always so easy to tell how much a product contains, if any - it looks the same whether there is salt in it or not. And because most of us adults are eating more than our recommended maximum daily amount of salt, which is 6g (about a teaspoon), we are often so used to the taste of it that we’re more likely to notice when it’s not there than when it is. So whereas we may be more alert to the fat or sugar in foods, it’s easy to forget about salt.

This is a problem, because over time, eating too much salt is linked to increased blood pressure. That’s why we believe it’s really important to have clear information on the front of food packaging. Traffic light colours and the words high, medium or low would mean that at a glance you can see what a product is like health-wise. When these two elements are combined with Guideline Daily Amount (GDA) information it’s the ideal combination to provide us with the information we need to make a real choice. At least then we know what we are getting into!

If you battling to understand food labels in your local shop, we have useful tips to help you get to grips with them.

But of course, the report shouldn’t put you off packaged salads entirely - they can be a healthy choice. Encouragingly the survey highlighted that a number of the companies had reformulated their products to reduce their salt content since 2005, which can only be a good thing. If some of the worst offenders also start to follow suit then it will be a real achievement.

For now though, the best way to really know what’s in the food you’re eating (and also to save money) is to make it yourself. Even the most reluctant cook can make a salad, but don’t get stuck in a lettuce, tomato, cucumber rut. Take a look at our recipe finder to add a bit of variety and try our flaked cherry tomato pasta salad or chicken rice salad – four green lights for both of them. Hearty, healthy and tasty - and without a salt cellar in sight!

Our free Heart Healthy Recipe Finder is available as an iPhone app, which even allows you to search for recipes suitable for people with high blood pressure or high cholesterol. You can also access it online through our free Heart Matters service.

What do my numbers really mean?

What do my numbers really mean?

I have my blood pressure checked fairly regularly. Generally, as long as my doctor doesn’t look worried by the digits he types into my medical records, I’m happy.

Sometimes I might ask what the reading is: “blah blah over blah” he replies cheerily. I nod my head and smile, none the wiser.

I’m familiar with the style of blood pressure readings, and know that there’s a big number ‘over’ a small number, but I wanted to find out what those numbers really mean…

Put simply, blood pressure is the pressure of blood in your arteries - the tubes that carry your blood from your heart to your brain and the rest of your body. You need a certain amount of pressure to get the blood around your body.

Your heart pumps in a regular rhythm squeezing oxygen-rich blood out of the big main artery – the aorta – which divides and branches into smaller and smaller vessels, nourishing every organ and tissue in the body.

The pressure of blood flowing through your arteries varies according to whether the heart is pumping or relaxing. Each time your heart pumps it contracts and blood is squeezed out, it creates a surge of pressure in the arteries. It’s this peak in pressure against the inside walls of your arteries that gives the top reading, which in medical terms is called your ‘systolic’ pressure.

After each beat/pump of your heart it has to relax to refill with blood, and the pressure of blood in your arteries falls, and this is the bottom reading. This is called your ‘diastolic’ pressure.

So, taking these two measurements give a reading of how much pressure your blood places on the inside walls of your arteries. This is blood pressure.

You should have your blood pressure measured so that you know what your target is. If you don’t have heart or circulatory disease, diabetes or kidney disease your target is to have a blood pressure below 140/85mmHg. (mmHg stands for millimetres of mercury, which are the units that are used to measure blood pressure).

However, if you have heart or circulatory disease – including being told you have coronary heart disease, angina, heart attack or stroke, have diabetes or kidney disease then your blood pressure should be below 130/80mmHg.

Ideally though your blood pressure would be quite well below these levels.

Know Your Numbers week starts today. We’ve got lots of booklets and info online about the ways to help your maintain a healthy blood pressure.
