Reducing your risk for dementia

Researchers are still trying to fully understand how the various forms of dementia develop. Without this understanding, there is no definitive way to prevent dementia, but there are simple steps you can take in your day to day life to help lower your risk of developing dementia. A healthy lifestyle can help reduce a variety of health conditions, such as cardiovascular diseases, which is itself a risk factor for dementia. Understanding the risk factors associated with dementia can enable you to act, reducing your risk for dementia.

How to reduce your risk of dementia

Creating a healthy lifestyle is the best way to reduce your risk of dementia, this can be done by understanding the risk factors associated with dementia and leading a life that manages them. Some risk factors we are able to change while others are more difficult or impossible to alter. Our genes and age are two risk factors that we don’t have control over. Although there are risk factors that we can not control there are many that we can. Research has shown that living a heart-healthy lifestyle is also a healthy brain lifestyle. Leading a healthy lifestyle and therefore reducing your risk of dementia can be done in the following ways:

1. Eating a well balanced, healthy diet

2. Maintaining a healthy weight

3. Exercising

4. Managing alcohol intake

5. Quit smoking

6. Maintaining a healthy blood pressure

Reducing the risk of dementia through diet

Through a healthy diet, your risk of developing high blood pressure, high cholesterol, becoming obese and developing type 2 diabetes can be reduced. A diet that is high in sugar, salt, saturated fats and low in fibre can increase your risk of developing these conditions. No one is perfect but try to follow the dietary recommendations as often as you can.

  • Aim for 5 portions of fruits and vegetables a day, this should make up over a third of the food you consume each day. A variety of fresh, tinned, frozen, dried and juiced can be worked into your daily meals. Fruits and vegetables are a great source of vitamins, minerals and fibre!

  • Starchy foods should make up the next roughly third of your diet. Aim for wholegrain varieties as these are high in fibre. Starchy foods also provide a great source of energy.

  • Dairy and dairy alternatives are a source of vitamins, proteins and calcium. Calcium plays a critical role in keeping bones strong. Where possible revert to options that are low in fat and sugar, this could be low-fat milk or low-fat yoghurt.

  • Beans, pulses, fish, eggs and meat are a good source of protein. Beans, peas and lentils are a great alternative to meat as they are high in fibre while low in fat. Aim for lean cuts of meat and 1 to 2 servings of fish a week.

  • A small amount of unsaturated fats are incorporated into your diet. These could be sunflower oil or vegetable oil.

  • Foods high in sugar, fat and salt should be eaten less frequently. This includes biscuits, sugary soft drinks, butter and ice cream.

  • And finally, water! Drink plenty of water, about 6 to 8 cups or glasses a day.
