Top tips for good heart health
- Cut down on saturated fat and replace with unsaturated fats – for example swap butter and coconut oil for rapeseed, olive and sunflower oils and spreads made from these.
- Have fish twice a week – one should be an oily type (such as mackerel, salmon or sardines).
- Watch your salt intake – Aim for less than 6g a day. Check the nutrition label on foods, and don’t add salt in cooking or at the table.
- Include high-fibre and wholegrain foods in your diet like wholegrain breakfast cereals, wholewheat pasta and pulses (e.g. lentils and beans). Fruit and vegetables are good fibre providers too.
- Give up smoking – this is one of the best things you can do to protect your heart.
- Keep active – aim for at least 150 minutes a week (around 30 minutes a day, 5 days a week) of moderate physical activity.
- Don’t drink to excess – adults should drink no more than 14 units a week, with several alcohol-free days each week.
- Aim for a healthy weight.
Heart disease and stroke
Heart disease and stroke are a major cause of death worldwide. In the UK, heart disease by itself is the biggest single cause of death; 15% of male and 10% of female deaths in 2014.
The number of deaths from heart disease have been decreasing in recent years but it is still one of the major cause of premature death (before 75 years) in the UK and a leading cause of ill health. But the good news is - it is largely preventable! Eating a healthy diet can help reduce your risk of heart disease and stroke.
The condition that causes most heart attacks and strokes is known as atherosclerosis
- Atherosclerosis is the build-up of fatty material inside arteries (blood vessels) like the coronary arteries that supply blood to the heart.
- The build-up of fatty material causes a narrowing in the artery, and as these become more severe they can restrict the flow of blood so enough blood can’t reach the heart.
- This can cause the symptoms of angina (such as chest pain and shortness of breath).
- If the fatty material breaks down (or ruptures), a blood clot can form, which can completely block the artery and lead to a heart attack.
- Strokes occur if such ruptures happen in arteries in the brain, stopping the flow of blood.
Who is at risk?
There are a number of risk factors for atherosclerosis and heart disease. A risk factor is something that that increases your chance of getting a disease.
- High blood pressure (hypertension)
Having high blood pressure puts strain on your heart that can lead to your blood vessels becoming damaged, making them more at risk of heart disease.
Quitting smoking is the single best thing you can do for your heart health.
- High blood cholesterol
High levels of cholesterol (a type of fatty substance) in the blood can build up in the walls of the coronary arteries, restricting blood flow to the heart and rest of the body.
The increased levels of blood glucose that can occur in type 1 and type 2 diabetes can damage the coronary arteries, increasing the chances of heart disease developing.
- Lack of exercise
Not exercising regularly increases the chance of high blood pressure, higher cholesterol levels and overweight and obesity. These are all risk factors for developing heart disease.
- Being overweight or obese
Research shows that being overweight or obese can raise your blood cholesterol levels, increase your blood pressure and increase your risk of developing type 2 diabetes.
- Family history of heart disease
You are considered to have a family history of cardiovascular disease (CVD) if your father or brother was under age 55 years when they were diagnosed with CVD, or your mother or sister was under age 65 years when they were diagnosed with CVD.
- Ethnic background
For the South Asian population (Bangladeshis, Indians and Pakistanis), and people with an African Caribbean background, CVD risk can be higher than for the rest of the UK population.
Your risk of developing heart disease increases with age.
Men are more likely to develop heart disease earlier than women.
The more risk factors you have, the greater your personal risk. But there are many things you can do to reduce your overall risk and keep your heart healthy. It’s never too late to start!
Even though you can’t do anything to change some of these risk factors, there are a number of lifestyle behaviours that put you at increased risk that can be changed. The main ones are:
- a poor diet
- excessive alcohol consumption
- lack of physical activity
These factors contribute to the risk of obesity, type 2 diabetes, high blood pressure and high cholesterol levels, which are some of the strongest risk factors for heart disease.
Maintaining a healthy bodyweight
Maintaining a healthy bodyweight and shape can significantly protect your heart. People who are overweight or obese tend to have a higher risk of certain risk factors for heart disease, such as increased levels of blood cholesterol, high blood pressure and an increased risk of developing type 2 diabetes.
As well as bodyweight [measured as body mass index (BMI)], your shape, can affect your health risk. If you are overweight and carry fat around the waist (apple–shaped), you are at greater risk than if you carry fat on the hips and thighs (pear-shaped).
- If you are a man, your chance of developing health problems is higher if your waist measurement is more than 94 cm (37 inches), and higher still if it is more than 102 cm (40 inches).
- If you are a woman, your chance of developing health problems is higher if your waist measurement is more than 80 cm (31.5 inches), and higher still if it is more than 88 cm (34.5 inches).
- Type 2 diabetes prevalence is strongly associated with ethnicity. The International Diabetes Federation and South Asian Health Foundation are in agreement that men from South Asian and Chinese ethnic groups are at increased risk of type 2 diabetes if waist size is greater than 90 cm.
Together with being physically active, eating a healthy, balanced diet will help you maintain a healthy bodyweight as well as providing your body with all the vitamins, minerals and other nutrients it needs to keep healthy. Read on for top tips for eating to keep your heart healthy!
Eating to keep your heart healthy
The Eatwell Guide is the UK's healthy eating model for the general population. It is a practical tool to help us to make healthy choices about the foods and drinks we choose to consume. Some of the healthy eating guidelines in the Eatwell Guide may be particularly relevant if you are looking to eat well to protect your heart. Good dietary patterns that include wholegrains, fruit and vegetables, nuts and seeds, oily fish and choosing unsaturated fats (such as the Mediterranean dietary pattern) are important for good heart health. Following the Eatwell Guide will help you to choose a better dietary pattern.
Food or nutrient
Importance for heart health
Fish and oily fish
There is not enough evidence to recommend supplements including omega-3 capsules to reduce CVD risk, but eating at least 1 portion of oily fish is included in dietary advice.
Aim to eat at least two portions (2 x 140g) of sustainably-sourced fish each week, at least one of which should be oily fish. Examples of oily fish include mackerel, salmon and sardines.
Too much saturated fat in the diet can raise your cholesterol, which increases the risk of heart disease. Current UK government guidelines advise cutting down on saturated fat and replacing with some unsaturated fat. The Committee that advises the government on nutrition is looking at the most recent evidence for saturated fat and heart health, but the UK guidelines are based on the best available evidence at the moment.
To reduce saturated fat:
Trans fats are found in partially hydrogenated vegetable oils (industrial) and naturally in small amounts in meat and dairy products. Industrial trans fats have been shown to have an adverse effect on blood cholesterol. Concern about the health effects of consuming high intakes of trans fats has led to changes in manufacturing practices in recent years. Fat spreads sold in the UK do not now contain trans fats and average trans fatty acid intake in the UK diet is now well below the recommended limit.
Wholegrain and high-fibre foods
Scientific reviews have reported that increased intakes of fibre in the diet may reduce risk of heart disease.
Eat a mixture of different wholegrain and high-fibre products when possible, such as:
Foods such as oats and barley contain a type of fibre known as beta glucan, which may help to reduce cholesterol levels if enough is eaten.
Salt is the main source of sodium in the diet, a high intake of which is related to high blood pressure.
Adults should be aiming for no more than 6g of salt each day.
Most of the salt we consume is from salt added during the processing and manufacture of foods for flavour, texture and preservation, like bread, bacon, ham, cheese and soups and sauces.
Try and choose foods with lower levels of salt by checking the salt content on labels and don’t add any extra to cooking or at the table.
Fruit and vegetables
Eat at least 5 portions of a variety of fruit and vegetables every day. A portion of beans or lentils also counts towards 1 of your 5 A DAY.
Foods with added plant sterols and stanols
Foods with added plant stanols and sterols, eaten regularly so as to provide about 2g stanols/sterols per day, can help lower raised cholesterol levels.
These food products are targeted at people with high cholesterol levels, A variety of such products are now available including spreads, yogurts, and yogurt drinks. These foods are not a replacement for a healthy, balanced diet or for any cholesterol lowering medication Whilst there is evidence that these ingredients have a cholesterol lowering effect, there is no evidence to show they will lead to fewer heart attacks.
Top tips for ethnic diets
It is known that some population groups such as South Asians (Bangladeshis, Indians and Pakistanis) and people with an African Caribbean background can have a higher risk of CVD than the rest of the UK population.
Here are some healthy eating tips for ethnic diets to help you look after your heart.
- Cut down on cooking with ghee, butter, palm oil or coconut oil/milk/cream, as these types of fat are high in saturated fat. Instead use oils that are high in unsaturated fat (monounsaturates and polyunsaturates), such as rapeseed, olive and sunflower oils and spreads.
- Avoid adding ghee or oil to foods such as chapattis or dhal
- Use lean cuts of red meat such as lamb, beef, mutton and goat, as these varieties can be high in fat.
- Only eat foods high in calories and fats occasionally, such as for example cakes, biscuits, samosas, pakoras and fried plantain. Savoury Indian snacks and sweets should also be limited in the diet as they are high in calories, sugars and fat.
- Choose wholemeal or wholegrain varieties of starchy foods such as chapatti, wholemeal pitta bread, boiled brown rice or potatoes instead of paratha, puri or fried potatoes.
- Choose less salty foods such as salt fish, bacon and salty snack foods (e.g. crisps and salted nuts) and don’t add salt when cooking.
- Help reach your 5 A DAY by adding vegetables and pulses like okra, kidney beans and black eyed peas to curries and stews.
Healthy eating is just one part of a healthy lifestyle. It is also important to consider other risk factors that may contribute towards your risk of heart disease.
Here are some tips to help you look after your heart:
Give up smoking
You are nearly twice as likely to have a heart attack if you smoke compared to people who have never smoked. Therefore, giving up smoking is one of the most important things you can do to protect your heart. The chemicals in smoke reduce the amount of oxygen your blood can carry to your heart and body; raise your heart rate and blood pressure so your heart has to work harder; damage the lining of your arteries (blood vessels), causing a build-up of fatty deposits; and also make the blood more likely to clot (thicken).
If you’re thinking about quitting smoking, why not get some specialist help and support from your local Stop Smoking Service https://www.nhs.uk/smokefree/help-and-advice/local-support-services-helplines
Take part in physical activity
Being inactive is a major health risk and one of the main causes of death and ill health in the UK.
Physical activity is important to:
You should aim for 150 minutes of moderate intensity physical activity (when you feel warm and slightly out of breath) a week. You could do this by doing 30 minutes of activity on 5 days of the week, but it could also be broken up into smaller sessions of 10 minutes or more. If you can do more, then that is great but be careful not to overdo it to start with. If you need to lose weight then you should aim for 45-60 minutes of moderate exercise every day. Talk to your GP before starting on a new exercise programme, especially if you have a history of heart disease, stroke or other health problems.
When you take part in activity, your body needs more oxygen and so your heart and lungs have to work harder. This helps to make your heart and blood vessels become more efficient over time. It also helps develop your stamina (how long you can be physically active for). Brisk walking, dancing, cycling and swimming are all great examples. So start at a pace that suits you and gradually increase what you are able to do.
Being more active doesn't have to mean joining a gym! Even pushing a lawnmower counts!
No matter how much physical activity you do, it’s important to avoid sitting down for long periods of time, for example whilst watching TV, using a computer, reading and travelling by car, bus or train. Being seated for long periods of time is bad for your health and has been linked to weight gain.
Drink alcohol moderately
Regularly drinking more alcohol than we are recommended over a long period of time raises blood pressure, which is a risk factor for heart disease and stroke, It can also a weaken the heart muscle so the heart can’t work as well. Binge drinking (drinking more than 6 units a day for women or 8 units a day for men) is a risk factor for heart disease.
There has been some evidence that for heart disease, drinking alcohol at low levels may be good for our hearts (compared to not drinking). However, when looking at total mortality – risk of death from all causes - a recent government review found that the protective effect from drinking alcohol regularly at low levels appears to be important only for women aged 55 years and over, and that for the majority of adults any possible benefit to heart conditions are outweighed by the increase in risk from other health conditions such as increased risk of some cancers.
So although very low levels of alcohol may have some protective effects against heart disease, this is more than outweighed by the adverse effects of alcohol on other health conditions.
Alcohol is not advised as a way of achieving better heart health, rather this can be better done through exercise, diet, not smoking and managing risk factors such as high blood pressure and high cholesterol levels.
The new recommendations for alcohol to keep any health risks low are that:
- Men should not drink more than 14 units of alcohol each week, the same level as for women.
- Men and women should have several alcohol-free days each week.
A standard glass of 12% ABV wine (175ml) is equivalent to about 2 units, and 1 pint of ordinary beer is also the equivalent to 2 units.
