There is a link between type 2 diabetes and diet : By making some simple changes to your diet you could completely reverse your type 2 diabetes.

Over 30 million people in the U.S. have diabetes, and the majority of them have type 2 diabetes. (1)

In the UK, it is estimated by Diabetes UK that, if nothing changes, over 5 million people will have this condition by 2025. Everywhere the rates of type two diabetes are rising, causing enormous health problems and suffering.

Fortunately, there is a lot of evidence of a link between type two diabetes and diet.

While many cases of type 2 diabetes can be prevented, it remains for adults the leading cause of diabetes-related complications.

These complications include  blindness, non-traumatic amputations, and chronic kidney failure.

What is type 2 diabetes?

 

Type 2 diabetes is a condition which occurs when the body can no longer correctly use the insulin that it produces.

This is also referred to as insulin resistance.

Normally, when we eat, our food is converted into glucose to be used for energy.

Insulin is produced which enables this glucose to leave the blood and enter our cells to be absorbed by the body.

When a person has type 2 diabetes, their body cannot respond correctly to this insulin, so the body reacts by initially producing more.

However, there comes a time when the body can no longer produce enough insulin and so the glucose cannot enter the cells.

Instead, the glucose stays in the blood and blood/sugar levels rise dangerously.

The result is very serious damage to multiple parts of the entire body.

Who gets type 2 diabetes?

It has been known for some time that obesity is by far the biggest cause of type two diabetes.

Further, a BMI of over 30 increases the risk of developing diabetes by a massive 80%.

Influence of genes

There is also evidence that genetics plays a part. If either parent has the condition, then there is an increased risk of you developing it too.

Other risk factors include smoking, being of South Asian or African-Caribbean descent, having raised blood pressure and raised cholesterol levels.

Type 2 diabetes can also be cauced by Polysystic ovarian syndrome –  a disorder of hormone balance.

Plus being older than 45 will also cause your risk to increase.

However, there is no doubt;  obesity is the biggest cause.

Due to this, the spotlight is now on the type of diet which may cause or prevent this major health issue.

who's at risk for diabetes - type two diabetes and diet

Obesity and type 2 diabetes

One study at Harvard University, which was published in Science, suggested that the cells of an overweight person become stressed.

This is because there is a membrane  inside your cells called the endoplasmic reticulum.

This membrane can become stressed by trying to  process too  many nutrients.

When this occurs,  the membrane becomes stressed and it sends a signal to the cell to turn down the insulin receptors on its surface.

When this happens too often, it will cause  insulin resistance.

Once you have insulin resistance, you’ll develop the very high blood/sugar levels which cause type 2 diabetes.

Furthermore, overweight and obese people generally take less exercise which also increases the risk.

Unfortunately, lack of exercise will cause a loss of lean muscle mass.

This lean muscle mass is important in helping to prevent both insulin resistance and type two diabetes.

Which foods are implicated in the development of type 2 diabetes?

Type two diabetes and diet

Your body has differing hormonal responses to different types of food. Some foods are much more likely to spike blood sugar that others.

Carbohydrates are the macro nutrients that cause the biggest and quickest rise in blood sugar levels.

In contrast, proteins cause only a moderate rise and there is no rise at all in blood / sugar levels after eating fats.

Simple carbs in particular can be a problem for the body. They are able to affect blood/sugar levels more quickly than any other food group.

When a simple carbohydrate is eaten, blood sugar levels rapidly increase and the body produces insulin in response to this.

If you’re is eating a diet heavy in simple carbs this is  very common in the standard western diet.

Unfortunately, this diet will cause your body  to repeatedly send insulin out to deal with the sugar.

This does two things:

Insulin, which is the hormone which signals the body to store glucose as fat, attempts to send as much glucose to the fat cells as it can. This in time will lead to weight gain.

The cells, as already said, become stressed with too many nutrients and signal the cell walls to reduce insulin receptors.

By eating far too many simple carbs, and far too often, the chances of becoming insulin resistant and developing type two diabetes increase significantly.

It is important both for the prevention of and the management of type two diabetes to control the amount of simple carbs eaten.

Which foods contain simple carbohydrates?

Carbohydrate heavy foods come in two main groups.

While both need to be reduced, the simple carbs are more sugar-spiking than complex carbs.

This is because complex carbs  contain fiber and starch which helps to reduce the speed of the insulin response.

The top carb which will put you at risk of type 2 diabetes

The worst carb of all is Sugar. This is the number one culprit, being 100% carb.

Consumption of sugar implicated in many diseases and health issues and not just in type two diabetes.

Other sugar products that should be limited are:

  • Honey
  • Cane Sugar
  • Corn Syrup
  • Maple Syrup
  • Agave Nectar

Also limit or avoid other simple carb foods such as:

  • Grains – white flour, oats, barley, white rice found in cakes, pastry, cookies, pasta and bread but hidden in many other ready-made meals.
  • Fruit juice
  • Sweets/candy
  • Breakfast cereals
  • Milk
  • Jam
  • Chocolate
  • Most ready meals

Further, these Complex carb foods should also be limited:

  • Buckwheat
  • Oat bran
  • Brown rice
  • Multi-grain bread
  • Oatmeal
  • Lentils
  • Kidney beans
  • most  below ground vegetables
  • Garbanzo beans

A very general rule of thumb would be to avoid the simple carbohydrates altogether and limit complex carbs.

Simple carbs are often foods of very limited nutritional value and contain few if any vitamins or minerals.

Also be aware that many “diet” foods have had the fat removed only for it to be replaced by sugar.

Often called fructose, corn syrup or dextrose. There are more than 50 different names used by the food industry to describe sugar.

Complex carbohydrates contain fiber, a valuable addition to your diet, and should not be avoided, but limited.

This is because we need nothing like the 200g-300g of carbs each day which is now consumed in the average western diet.

The starches in complex carbs also serve to slow down the sugar/insulin surge more than simple carbs which do not contain starch.

Carbs are implicated in the development of type 2 diabetes

Way back in 1977 the food pyramid was first introduced as a guide to healthy eating.

It suggested that we should all base our diets on carbs, an astonishing 6 -11 servings each day was suggested as being “healthy”

Once you know that carbs cause an insulin reaction in our bodies, it’s difficult to see how eating such a carb heavy diet could have ever have been thought of as healthy.

Following this dietary advice, type two diabetes rates went through the roof.

Sadly, this is set to climb further unless people begin to understand the carb – insulin resistance link.

It’s important to remember that we can healthy eat a certain amount of carbohydrates in our diet.

However, there is no such thing as an essential carbohydrate. Your body is able to produce all the glucose it needs even in the absence of carbs.

Realistically though, it would be  difficult and unneccesary to attempt to omit all carbs.

The science

A low carb diet has been shown to help people to regulate their blood sugar levels.

A study was conducted at Bispebjerg Hospital. They  collaborated with, among other partners, Aarhus University and the Department of Nutrition, Exercise and Sports at the University of Copenhagen.

Their findings support the suggestion that  low carb diets promote steady blood/glucose levels.

The authors of the study determined  that:

Patients with type 2 diabetes improve their ability to regulate their blood sugar levels if they eat food with a reduced carbohydrate content and an increased share of protein and fat.”

This study deliberately sought to take weight-loss out of the picture.

For this reasonand the subjects ate protein and fats in sufficient amounts to maintain their body weight.

The scientists felt that other studies into the low carb- diabetes link muddied the waters somewhat by putting the subjects on a low carb diet which also caused weight loss.

However, there are some studies that have stated that they have not found a significant link between the two.

The take home message

type two diabetes and diet

It has been proven that there is a strong link between a  carb heavy diet and type 2 diabetes.

Further, The food pyramid and a growing amount of anecdotal evidence was taken into account.

While there is most definitely a link between eating a carb heavy diet and developing diabetes it’s important to note that this does not conclude that carb heavy diets cause the condition.

Further, consuming too  many carbs will cause obesity. To learn more about carbs and weight gain read:

(stop counting calories lose weight and gain control).

Obesity and type 2 diabetes  go hand-in-hand  but the conclusion amongst scientists is unclear.

While some feel strongly that carb heavy diets do cause diabetes, it’s possible that the pathway to type 2 is actually too many carbs – weight gain – type two diabetes.

However, the exact mechanism is less important that the fact that in either case, consuming too many carbs will result in the same outome.

You will increase your risk of developing a very serious health condition if you eat a carb heavy diet.

While the science is still not conclusive, there does seem to be a lot of evidence, and certainly enough evidence to give serious consideration to trying a low carb diet for yourself.

Dr David Unwin wrote in a UK national paper low carb diet as a way of reversing diabetes  of his success in helping his patients to overcome type two diabetes through diet alone.

He states:

By switching to this approach, 40 per cent of my patients actually reversed their type 2 diabetes so they no longer need medication — their blood pressure, cholesterol and liver function have also improved.

Thanks to this work, in 2016 I was named NHS Innovator of the Year and my approach is now being taught to GPs across the country through the Royal College of General Practitioners — I even met the Health Secretary Matt Hancock to discuss low carb for type 2 diabetes.”

That’s more than enough evidence for me.
