The Worst Foods for Diabetics

Learning how to eat to prevent diabetes and how to eat if you have diabetes or prediabetes can help you take control of your health. A diet of vegetables, nuts, seeds, beans, and fresh fruit can prevent and even reverse diabetes while promoting long-term health.

The worst foods for diabetes – the foods that elevate blood sugar, reduce insulin sensitivity and increase type 2 diabetes risk – unfortunately are the foods that are most common in the standard American diet.

1. Added Sugars
Since diabetes is characterized by abnormally elevated blood glucose levels, of course, it is wise to avoid the foods that cause dangerously high spikes in blood glucose – primarily refined foods such as sugar-sweetened beverages, devoid of fiber to slow the absorption of glucose into the blood.

Fruit juices and sugary processed foods and desserts have similar effects. These foods promote hyperglycemia and insulin resistance, and promote the formation of advanced glycation end products (AGEs) in the body.

AGEs alter the normal, healthy function of cellular proteins, stiffen the blood vessels, accelerate aging, and promote diabetes complications.

2. Refined Grains (White Rice and White Flour Products)
Refined carbohydrates like white rice, white pasta, and white bread are missing the fiber from the original grain, so they raise blood glucose higher and faster than their intact, unprocessed counterparts.

In a six-year study of 65,000 women, those with diets high in refined carbohydrates from white bread, white rice, and pasta were 2.5 times as likely to be diagnosed with type 2 diabetes compared to those who ate lower-glycemic-load foods, such as intact whole grains and whole wheat bread.

An analysis of four prospective studies on white rice consumption and diabetes foundthat each daily serving of white rice increased the risk of diabetes by 11%.

In addition to the glucose-raising effects, cooked starchy foods also contain AGEs, which promote aging and diabetes complications.

3. Fried Foods
Potato chips, French fries, doughnuts and other fried starches start with a high-glycemic food, and then pile on a huge number of low-nutrient calories in the form of oil.

Plus, like other cooked starches, fried foods contain AGEs.

4. Trans Fats (Margarine, Shortening, Fast Food, Processed Baked Goods)
Diabetes accelerates cardiovascular disease. Because the vast majority of diabetics (more than 80%) die from cardiovascular disease, any food that increases cardiovascular risk will be especially problematic for those with diabetes.

Trans fat intake is a strong dietary risk factor for heart disease; even a small amount of trans fat intake increases risk.

In addition to their cardiovascular effects, saturated and trans fats reduce insulin sensitivity, leading to elevated glucose and insulin levels, and greater risk of diabetes.

5. Red and Processed Meats
At first glance, it may seem like the dietary effects on diabetes would be only relevant to carbohydrate-containing foods. The more low-carbohydrate, high-protein foods in your diet, the better; those foods don’t directly raise blood glucose.

However, that is a too simplistic view of the development of type 2 diabetes. Type 2 diabetes is not only driven by elevated glucose levels, but also by chronicinflammation, oxidative stress, and alterations in circulating lipids (fats).

Many diabetics have come to believe that if sugar and refined grains and other high-glycemic foods raise blood sugar and triglycerides, they should avoid them and eat more animal protein to keep their blood glucose levels in check.

However, several studies have now confirmed that high intake of meat increases the risk of diabetes.

A meta-analysis of 12 studies concluded that high total meat intake increased type 2 diabetes risk 17% above low intake, high red meat intake increased risk 21%, and high processed meat intake increased risk 41%.

6. Whole Eggs
Eating 5 eggs/week or more has been associated with an increased risk of developing type 2 diabetes.

When it comes to heart disease, eggs have been a controversial topic. However, for those with diabetes, the research is not controversial; there are clear links in many observational studies to large increases in risk.

Large prospective studies such as The Nurses’ Health Study, Health Professionals Follow-up Study, and Physicians’ Health Study reported that diabetics who eat more than one egg/day double their cardiovascular disease or death risk compared to diabetics that ate less than one egg per week.

Another study of diabetics reported that those eating one egg/day or more had a fivefold increase in risk of death from cardiovascular disease.
