Top 12 tips for a healthy heart

In Australia, 1 in 6 adults – or 4.2 million people – have heart disease. It's the leading cause of death, with more than 40,000 lives lost each year.

Top 12 tips for a healthy heart

1. Eat the right fats

In a healthy diet, fats should account for about 20-35% of the energy you eat. Healthy fats supply valuable fatty acids that help nurture your body and brain, and help you absorb important fat-soluble vitamins and nutrients like vitamins A, D, E, K.

There are different types of dietary fats in food, including unsaturated fats, saturated fats, and trans fats.

Healthy fats, including unsaturated fats and omega 3s - from avocados and nuts for example - will reduce your risk of developing heart disease whereas unhealthy fats, including saturated and trans fats - fatty meats, processed pastries, cakes and pies - will increase your risk.

When it comes to heart disease and healthy eating in general, it’s best to reduce your intake of saturated and trans fats as much as possible. By reducing your saturated fat and adding in healthy fats, you can lower your LDL (low density lipoprotein) ‘bad’ cholesterol by about 6-8%!

Here are some tips:

• avoid processed meats like salami and sausages
• trim the fat off meat and choose leaner cuts
• remove the skin from chicken
• try eating more plant proteins like legumes instead of meat 2-3 times per week
• choose low-fat dairy products or use calcium fortified dairy alternatives on your cereal or in your coffee instead
• replace butter, ghee, and coconut oil with extra virgin cold pressed olive oil for cooking
• reduce your intake of processed and refined foods

Also try to include some heart protective unsaturated fats in your diet each day:

• add 1tbs of chia seeds or freshly ground linseeds (flaxseeds) to your cereal every morning
• enjoy lightly roasted sunflower and pumpkin seeds sprinkled over your cereal, yoghurt, salads, or meals
• have a handful (30g) of unsalted nuts as a snack
• use avocado or nut butters like peanut butter as spreads
• cook with extra virgin cold pressed olive oil and use it as a dressing for salads, soups and meals.
• Add legumes like chickpeas, butter beans and cannelini beans to soups and sauces or delicious dips

2. Choose wholegrains

The research on the benefits of wholegrains for heart health is strong. Wholegrain foods, with fibre and rich in nutrients, can help your heart health.

Try to replace refined grains in your diet with wholegrains, including wholegrain cereals, brown grainy breads, rolled oats, brown rice and pasta, pearled barley, quinoa, buckwheat and sorghum.

Did you know? 
A recent Danish study of 55,000 adults followed over 13 years showed that those who consumed the most amount of wholegrains had a 25% lower risk of having a heart attack than those that consumed the least.

3. Boost fruits and vegetables

Eating a variety of fruits and vegetables daily is important for heart disease prevention. Along with valuable fibre, fruits and vegetables have important antioxidants and phytochemicals which help to protect your heart.

• add fresh fruits to your cereal or smoothies
• pack in a piece of fruit as a snack
• have fresh veggie sticks with hummus or a tzatziki dip
• fill your wraps and sandwiches with a variety of salads, sprouts, beans and legumes, tomato, cucumber, grated carrot, and olives
• fill half your plate with fresh, lightly steamed, sauteed, or stir-fried vegetables at lunch and dinner.
  

4. Increase plant sterols

Plant sterols help to lower your cholesterol by blocking its absorption from food in your gut, meaning less cholesterol ends up in your bloodstream. Plant sterols are naturally found in very small amounts in plant foods, including plant based oils, nuts, seeds, wholegrains, breads, legumes, fruits and vegetables.

A plant-based diet can supply around 1/2g per day. But, if you need to manage your cholesterol, increasing the amount of plant sterols in your diet may help. Studies show that when 2g of plant sterols are added to the diet each day through a plant sterol enriched food (like cereal, milk or spread) or a plant sterol supplement, it can help reduce your LDL ‘bad’ cholesterol by about 9%!

5. Aim for more soluble fibres

Soluble or viscous fibres are components of plants that create a gel like texture when soaked or cooked. Some food examples include oats, barley, eggplant, legumes, psyllium husks, chia seeds, and linseeds (or flaxseeds). These fibres also help catch cholesterol in your gut, preventing it from being absorbed into your bloodstream. Studies show that about 10g of viscous fibres each day can lower LDL ‘bad’ cholesterol by around 3-5%.

Key ways to include more soluble fibres include:

• add 1 tbs of ground linseeds, chia seeds, or psyllium husks to your cereal each morning
• use oats in your cereal, smoothie, or in homemade muffins or breads
• add barley to soups or use instead of rice with some meals like risotto
• add cooked legumes like lentils, chickpeas, or red kidney beans to your salads, soups and stews regularly · use hummus on sandwiches and wraps (made from chickpeas)
• use baba ganoush (made form eggplant) as a dip or spread
• aim to include a variety of fruits (2 serves) and vegetables (5 serves) daily.
  

6. Eat soy

Soy foods including soy beans, soy milk, tofu and tempeh are heart healthy foods. The soy protein, fibre, omega-3 fatty acids, and isoflavones in soy foods can help to lower your cholesterol, improve blood pressure, and help keep your blood vessels flexible.

Consuming as many as 1-3 serves of soy per day (about 25g of soy protein), as part of a healthy balanced diet, can help lower your LDL ‘bad’ cholesterol by around 3-5% and improve heart health.

• adding calcium fortified soy to your cereal, porridge or smoothies every morning
• order soy milk based coffees or turmeric lattes
• use soy and linseed breads
• add firm tofu or tempeh to stir-fries or curries
• make chia seed puddings with soy milk

7. Munch on nuts and peanuts

Nuts and peanuts contain important amounts of fibre, polyunsaturated fats, magnesium, and vitamin E, which are all important for protecting your heart. If you consume ¼ cup (about 30g) of unsalted nuts each day, you can reduce your risk of heart disease by up to 27%! Or by 31% if peanuts are consumed. When it comes to nuts and cholesterol, about a ¼ cup can help lower your LDL ‘bad’ cholesterol near to 3-5%.

Add some nuts to your meals:

• have a handful of unsalted nuts as a midmorning snack
• make your own trail mix
• add them to your breakfast cereal, salad, stir-fry, or muffin mix
• make a creamy nut pesto
• use lightly baked nuts as delicious crunchy topping on yoghurt
• enjoy natural peanut butter or other nut paste in a smoothie or on brown grainy bread or wholegrain breakfast biscuits.
  

8. The portfolio foods

The portfolio foods include all the key dietary foods mentioned above (plant sterols, soluble/viscous fibres, soy protein, and nuts) which have an additive effect at lowering cholesterol when eaten in combination (over the course of a day).

These were first discovered by Professor David Jenkins at the University of Toronto, Canada. He showed that when those with high cholesterol ate a controlled low saturated fat diet it lowered their LDL ‘bad’ cholesterol by 9%, but when they ate a low saturated fat diet with portfolio foods, their LDL ‘bad’ cholesterol was lowered by 30% within 4 weeks!! Which provides the same effect as a low dose statin.

This is an amazing result considering if only a 10% reduction in LDL ‘bad’ cholesterol is achieved, it has the potential of saving about 3,000 Australian lives from heart disease and stroke each year.

So eating a low saturated fat diet with a combination of portfolio foods (plant sterols, viscous fibres, soy protein, and nuts), will provide an additional benefit to lowering your cholesterol than attempting any of these dietary measures alone.

And if you’re on statin medication already, eating portfolio foods - especially plant sterols - will allow your medication to work more efficiently.

9. Reduce salt

High salt intake can increase your heart disease risk by increasing your blood pressure levels.

While limiting the amount of salt you add to your food is important, most of your salt intake can come from processed foods. Read your food labels regularly and aim for foods with less than 400mg of sodium per 100g.

Tips to reduce your salt intake:

• avoid highly processed foods like processed snacks and chips
• gradually decrease the amount of salt added during cooking, so that your taste buds will adjust · use reduced salt or no added salt stock cubes
• use tomato pastes and purees to add flavour
• add a variety of herbs and spices to flavour your meals, including garlic, ginger, turmeric, pepper, coriander, parsley, oregano, basil, thyme, sage, rosemary, saffron, chives, mint and cinnamon

10. Be active!

Regular physical activity will increase your HDL ‘good’ cholesterol and keep your heart fit and strong, as well as helping you feel more energetic, happier and relaxed. Try to be physically active most days of the week for at least 30-40 minutes.

11. Keep a healthy body weight

Losing excess weight will help to improve your cholesterol levels, reduce blood pressure, and reduce inflammation. Try to keep your weight within the healthy weight range for your height. Speak to your health practitioner and dietitian for support.

12. Reduce alcohol and avoid tobacco

If you drink alcohol try to minimise the amount and keep to 2 standard drinks on any occasion. Like alcohol, smoking is very harmful for your heart and greatly increases cholesterol and your heart disease risk. If you’re a smoker, speak to your doctor on how to quit.
