All You Need To Know About Diabetes and Protein Consumption

Type 1 and 2 Diabetes


Before going any further in this article, it is important to establish the difference between Type 1 and Type 2 diabetes. There are only these two distinctive variants of the condition, yet many misconceptions and mischaracterisations continue to surround both Type 1 and Type 2.

Type 1 diabetes is often diagnosed in childhood, and thus, as mentioned previously, is passed on genetically. There is no association between Type 1 diabetes and any other health conditions, such as being overweight or obese. When Type 1 diabetes is diagnosed, individuals suffering with the condition often have higher ketone levels than is normal.

Treatment of Type 1 diabetes tends to focus on insulin, with injections being the usual course of treatment. Indeed, it is impossible to control Type 1 diabetes without taking insulin, meaning that although Type 2 diabetes is also serious, the Type 1 condition is generally considered to be more debilitating.

Challenges of Being a Diabetic

Conversely, Type 2 diabetes is usually diagnosed in those over the age of 30, and is indeed associated with excessive amounts of body weight in particular. People diagnosed with Type 2 diabetes often experience high blood pressure and cholesterol levels, and the condition is usually initially treated without medication or tablets, instead of addressing certain aspects of the diabetic’s lifestyle. Medical treatment can often be ramped up, though, as Type 2 diabetes develops and becomes cemented within an individual.

While Type 2 diabetes is certainly a serious condition, it is sometimes possible for the immune system to correct itself in the case of Type 2 diabetes, meaning that patients can come off medication, and may even cease to suffer with the symptoms associated with the condition. However, this doesn't necessarily mean that Type 2 diabetes is no longer present, rather that it is a more easily treatable condition than Type 1 diabetes, and one that will tend to wax and wane somewhat.

The Development of Diabetes

Type 1 diabetes is an autoimmune disease. This means that it emanates from the body mistakenly attacking itself, via the immune system. Those suffering from Type 1 diabetes will experience the immune system incorrectly targeting insulin-producing beta cells in the pancreatic system. Unfortunately, there is no known cure for this condition, and it is one that continues to grow in prominence. However, by treating the condition with insulin, Type 1 diabetes can be managed effectively.

Interestingly, Type 2 diabetes is completely different. Those suffering with Type 2 diabetes don't experience any autoimmune response, with the condition being characterised by the body losing its ability to respond appropriately to insulin - often described as insulin resistance. The body then compensates for this insulin deficit by creating an excess. However, it isn't always possible to produce a satisfactory amount, and the strain placed on beta cells by this level of insulin production can destroy them, further diminishing production of this important substance.

Challenges of Being a Diabetic

There is no doubt that the daily reality of being a diabetic is extremely challenging, not to mention the fact that the condition also carries long-term health implications. People with diabetes have to make many adjustments to their daily lives. However, the good news is that medical science has developed a wide variety of treatments that make it possible to manage diabetes, and still live a completely normal existence.

Firstly, it is essential for anyone suffering from diabetes to be constantly aware of the way that their bodies operate. Those with Type 2 diabetes need to monitor blood sugar levels regularly and take appropriate action on a daily basis. First and foremost, Type 1 diabetes sufferers must use insulin in order to ensure that their bodies operate satisfactorily.

Aside from these daily logistical challenges, there are also a wide variety of serious health conditions associated with both types of diabetes. High blood sugar levels can seriously damage the body, meaning that diabetics can often experience serious, and even life-threatening, health problems.

Chronic conditions associated with people with diabetes include the following: retinopathy of the eyes, problems with various limbs, heart attacks and strokes, kidney failure, nerve damage, gut disease, and a wide variety of related conditions, including cancer. A Hyperosmolar Hyperglycaemic State, caused by severe dehydration and very high blood sugars, is another serious health problem faced by those with Type 2 diabetes. And diabetic ketoacidosis, where a lack of insulin and high blood sugars leads to a build-up of ketones, can also result in death.

What this means is the way that diabetics fuel their bodies is of absolutely critical importance.

Diabetes and the Consumption of Fats and Carbohydrates

Everyone should attempt to eat a balanced diet, but in the case of people with diabetes this becomes even more important. We all need to follow a healthy, balanced diet that is low in fat, but balancing fats and carbohydrates becomes even more important for those dealing with Type 1 and Type 2 diabetes. It should be noted that fat is associated with cardiovascular disease, which is the biggest killer of people in the world bar none. As diabetics are at an increased risk of cardiovascular health problems, it is even more important for them to make healthy food choices.

Nonetheless, a diet completely devoid of fat would not be a healthy one, as the substance plays an important role in the functioning of the anatomy, and even brain functions. It is therefore important for diabetics to include a small amount of fat in their daily diet, as this substance performs a wide range of important functions.

These include:

  • supply energy for cells;
  • providing a fatty acids that are not manufactured by the body;
  • transporting fat-soluble vitamins;
  • playing an important role in the protection of vital organs;
  • being used in the production of hormones.
Diet for Diabetics

Nonetheless, it is also important for people with diabetes to closely monitor the amount of fat that they are consuming, as, aside from the cardiovascular risk, fats also contain a high number of calories, and are almost inherently associated with obesity. It goes without saying that being overweight is extremely dangerous for those suffering with diabetes, and thus the level of fat being consumed should be carefully monitored.

The same also applies to carbohydrates, not least because carbs spike blood sugar; obviously an extremely important facet of this food group for diabetics to understand. When those suffering with diabetes consume foods high in digestible carbohydrates, blood sugar levels can surge in a fairly short period of time. Any diabetic digesting a large quantity of carbohydrates will also require a high dose of insulin or diabetes medication in order to control their levels of blood sugar, and over a long period of time this is unsustainable.

And particularly for those with Type 1 diabetes, reducing carbohydrate consumption can significantly reduce the amount of insulin that sufferers need to inject. This can have a significant impact on the long-term prognosis of their condition. 

The Keto Diet

keto diet

With this in mind, many have advocated low-carb diets for people with diabetes, and many studies indeed support this approach to managing the condition. One of the most popular diets that has become a talking point in recent years is the keto diet, which is intended to induce a mild to moderate ketosis in those consuming it (this refers to a condition in which bodies burn ketones and fat, rather than sugar, as its main source of energy).

Keogenic diets have been prescribed for those suffering with diabetes for many years, and they do result in the blood sugar level and total amount of digestible carbohydrates being significantly reduced.

Due note however that if you are taking insulin for type 1 diabetes you must consult your physician before beginning the keto or any other diet program to ensure it is safe for you.

Numerous scientific studies have indicated that restricting carbohydrates to less than 50 grams per day can significantly reduce blood sugar levels, promote weight loss, and improve levels of beta cells in people with diabetes; obviously, all of which can be extremely helpful in managing the condition.

Another advantage of the ketogenic approach to diet is that improvements in people with diabetes have been noted to occur very quickly. Getting the body into a state of ketosis is relatively easy if one is disciplined with diet and dietary intake, and this can also help diabetics suffering with obesity to turn around their weight problems in a relatively short timeframe.

Of course, people with diabetes still need to consume some carbohydrates, and it is also important to understand precisely what food should be avoided, and what are good sources of carbs. There are many enjoyable carbohydrate-based foods that only have a minimal impact on blood sugar, but others cause it to spike rapidly, and should either being completely avoided by diabetics, or severely rationed.

Thus, those dealing with diabetes on a daily basis should generally avoid the following especially in large quanties:

  • Bakery products - such as loaves of bread, muffins, rolls, and bagels
  • Grains, including pasta, rice, corn, etc.
  • Potatoes, yams, and taro
  • Legumes, such as peas, beans, and lentils
  • Milk and any form of dairy product that is sweetened
  • Many fruits
  • Sweets, such as cakes, cookies, savoury pies, and ice cream.
  • Snack foods, such as pretzels, chips, and popcorn
  • Juice, soda, sweetened iced tea, and other sugar-sweetened drinks
  • Many types of alcoholic beverage, particularly beer.

Note that if your are following a strict ketogenic diet none of the above foods should be consumed.

There are healthy and beneficial foods included in the list above, but the fact remains that they do not constitute an optimal part of diet for anyone needing to manage blood sugar levels by consuming fewer carbohydrates. And there are healthy sources of carbs out there, such as lentils, apples, blueberries, unsweetened yogurt, oatmeal, quinoa, papaya, and wholegrain pasta.

The message here is that fat and carbohydrates should not be eliminated completely, or even neglected, but they must be managed extremely carefully, and diabetics should consume them in smaller quantities than is possible for the rest of the population, while choosing their sources carefully.

How much Protein Should Diabetics Consume?

diabetes and protein

So if you've been paying attention to the previous sections then you should be clear that it is extremely important for people with diabetes to consume a balanced diet. This also applies to protein, even though this critical dietary substance doesn't have a huge influence over blood sugar levels. However, it doesn't necessarily follow that those suffering with diabetes should consume more protein than is the case for normally adjusted individuals. Protein shakes can be a quick and easy way to add more protein to your daily diet.

As a general rule, it is accepted that people with diabetes should acquire around 20% of daily calories from proteins. However, diabetics looking to build muscle and train can afford to consume slightly more protein than average, without any particularly deleterious health effects. Research indicates that increasing protein consumption doesn't seem to have any appreciable impact on how sugar is digested or absorbed, or on blood sugar and insulin requirements. Again, always consult your physician before beginning an exercise program if you are diabetic.

This means that it is possible for a person with diabetes to utilize a high-protein diet, although medics are skeptical about any therapeutic benefits that this may have. It's fine to consume more protein than the average, but diabetics doing so shouldn't necessarily expect superior health outcomes, they should merely understand that it is safe to do so in moderation.

Good protein choices include plant-based foods, such as black, kidney, and pinto beans. Hummus and falafel are also extremely healthy, while almond butter, cashew butter, or natural peanut butter are also excellent choices. Oily fish, including catfish, cod, flounder, haddock, halibut, orange roughly, and tilapia, and lean meat, particularly poultry, can also be considered healthy sources of dietary protein.

And, lastly, protein powder is an excellent for diabetics who are active and in the gym on a regular basis.
