Need some foolproof advice on the best ways to lower blood sugar levels? It's an important aspect of your health – especially for anyone at risk of developing Type 2 diabetes, as well as those of us who have put on a few pounds recently. Do you suffer from sugar cravings, a mid-afternoon energy dip, or perhaps just comfort eating and weight gain? If so, this advice is for you.

What is blood sugar?

First, let’s talk about how blood sugar works. When we eat sweet or starchy food, or drink alcohol, our bodies break it down into glucose (sugar). As the amount of glucose in the blood goes up, we feel full of energy. Our bodies then release insulin, to lower blood sugar levels to normal. So far, so good. But sometimes the blood sugar levels spike too quickly.

Why do blood sugar levels spike?

  1. We consume food and drink high in sugar or starch
  2. This causes blood sugar to rise too quickly
  3. Our bodies create extra insulin to deal with it
  4. This lowers blood sugar levels
  5. We get a 'sugar crash'
  6. It makes us feel grumpy, tired and hungry
  7. We crave more sugar and starch
  8. We repeat the pattern

Why is a 'sugar crash' bad for you? 

If you often eat too many starchy or sugary foods, your body gets used to it. Then it starts to ignore the 'make more insulin' message. We call this 'insulin resistance'. It can lead to permanently high blood sugar levels. And that can cause poor health, weight gain, low mood and even Type 2 diabetes. 

Want to take control and avoid the 'sugar crash'? Here are 5 great ways to lower blood sugar levels:

Top 5 ways to lower blood sugar levels

Health experts have carried out excellent studies, around the world. Using their research, I can now reveal the best ways to lower your blood sugar levels.

1. Go green: eat leaves and low-GI foods

The best way to lower blood sugar levels, is to eat foods that release energy into your bloodstream slowly. These are called low-GI foods. What does GI mean? GI is short for the glycemic index – a list of foods that contain carbohydrates. Each food is given a rating to show how quickly it raises your blood sugar. 

Simply choose more of these low-GI foods to avoid sugar spikes and crashes. 

Best low-GI foods to lower blood sugar levels:

  • Leafy greens
  • Apple cider vinegar
  • Most fruits
  • Most vegetables, including beans
  • Whole grains
  • Pasta
  • Low-fat dairy foods, such as live natural yogurt
  • Nuts

The very best low-GI foods you can eat include leafy greens. They are high in fibre and nutrients like magnesium and vitamin A, which are known to help lower blood sugar levels. I recommend that you eat leafy greens as part of your super-healthy new diet. 

Why does blood sugar matter?  Studies in the US have shown that eating more green leafy vegetables can reduce the risk of developing Type 2 diabetes significantly. 

Apple cider vinegar is another excellent low-GI food to add to your healthy diet. 

How can cider vinegar help? The acetic acid in cider vinegar reduces certain enzymes in the stomach. Drinking a teaspoon of apple cider vinegar before a main meal can improve insulin sensitivity. And that's how cider vinegar helps to lower blood sugar levels. 

I like to choose raw, unfiltered apple cider vinegar. The best products contain ‘the Mother’ (the active part). (My favourite is Bragg Organic Apple Cider Vinegar.) 

2. Take a walk to lower blood sugar levels

Our ancestors knew that it was a good idea to go for a quick walk after a meal. But why?

Walking works like magic – here's how:

  • Walking raises your heart rate
  • You breathe harder
  • Your muscles use more glucose
  • Your body makes less insulin
  • Less insulin means less of the glucose is stored as fat

Diabetes – a walking cure. A recent study by the American Diabetes Association tested older adults who were at risk of Type 2 diabetes. They ate a meal, then walked on a treadmill for 15 minutes. The result? A lower blood sugar spike in the hours after the walk. 

The study also tested their blood sugar levels after a single 45-minute walk each day. Whether the long walk happened in the morning or the evening, this proved less effective than the short walk straight after eating. So our ancestors were right – a short walk works wonders after a meal.

3. Eat raspberries to lower blood sugar levels

Raspberries are packed full of vitamins, minerals and antioxidants to promote good health. But did you know that raspberries have a delicious side-effect? They lower blood sugar levels, too.

Red raspberries have anti-inflammatory and metabolism-stabilising properties. A study by the Illinois Institute of Technology found that raspberries can help reduce the risk of chronic diseases, including Type 2 diabetes.

Researchers found that people who ate two cups of red raspberries after a meal had much lower blood sugar levels, compared with those who ate no raspberries. The more raspberries they ate, the less insulin their bodies needed to make, to manage their blood glucose. This is exciting news, especially for pre-diabetics.

“People who are at risk of diabetes are often told to not eat any fruit because of their sugar content. But certain fruits – such as red raspberries – not only provide essential micronutrients, but also components such as 'anthocyanins' (which give them their colour), and fibre that has anti-diabetic actions,” explains Britt Burton-Freeman, a director at the Center for Nutrition Research, Illinois Tech.

Raspberries can reduce your risk of:

  • Type 2 diabetes
  • Cardiovascular disease
  • Obesity
  • Alzheimer's disease

If you are at risk of Type 2 diabetes, include fresh raspberries in your diet. It is  an “important strategy for slowing or reversing progression to disease”, says Britt.

4. Spice it up: cinnamon lowers blood sugar levels

Cinnamon is a super-spice you can use to lower blood sugar levels. A study by the USDA's Agricultural Research Service found that eating just 1g of cinnamon every day can:

  • Improve blood glucose level,
  • Increase insulin sensitivity
  • Help manage or even reverse Type 2 diabetes

5. Sleep for more than 6 hours a night

Poor sleep doesn’t just make us feel sluggish and grumpy. Poor sleep plays havoc with the body, by disrupting blood sugar levels, which surge as we snooze. For a healthy person, insulin can handle this sugar boost. It just tells the muscle, fat and liver cells to absorb the glucose from the blood, to keep levels balanced. If you are at risk of Type 2 diabetes, it's much more dangerous. In this case your insulin can’t do its job properly, so blood sugar levels will rise higher.

What causes Type 2 diabetes? Poor diet and obesity contribute to the risk of having diabetes. But did you know too little sleep can also put you at risk? 

One study found that people who often slept for less than 6 hours a night were twice as likely to develop diabetes or to have cells that were less sensitive to insulin. This was true even after researchers took other lifestyle behaviour into account. 

Can I party all night and catch up with sleep in the morning?  No, not too often. When you stay up late your body makes more of the stress hormone cortisol. This disrupts the way your insulin works. So, to lower blood sugar levels, try to get at least 7 hours of sleep each night.
