Which foods cause Diabetes?

February 11, 2026

There is no direct food that leads to diabetes. Nevertheless, the consumption of specific types of foods, especially high amounts of refined sugars, sugary beverages, processed meat, processed carbohydrates, and ultra processed snacks, comes with a high degree of risk to the development of type 2 diabetes. This danger increases exponentially in individuals who lack the required strength of the pancreas by inheritance or acquired condition, which could easily be identified using iridology and specific markings, discolouration, or lacunae in the respective zone of the pancreas in the iris.

Struggling to understand which foods can raise your risk of developing Type 2 diabetes? This video dives into the main dietary culprits—from excessive sugar to highly processed foods—and explores how they may contribute to insulin resistance, weight gain, inflammation, and imbalances in liver and pancreatic function.

Foods Most Strongly Linked to Increased Diabetes Risk

Sugary Drinks

One of the most frequent and consistently demonstrated risks factors of type 2 diabetes in the diet is regular consumption of sweet drinks. These beverages lead to acute recurrent increases in blood glucose and eventually lead to insulin resistance.

Examples of common high-risks are:

Fizzy soft drinks (cola, lemonade, energy drinks)
Fruit juices with added sugar
Iced tea drinks and coffee which have been sweetened
Sports beverages and sugar flavoured waters
Chocolate milk and milk substitutes that are sweetened

Processed and Red Meats

High frequency consumption of processed meat and large quantities of red meat has also been linked to a high risk of type 2 diabetes. This association is believed to be caused by saturated fats, preservatives (nitrates/nitrites), advanced glycation end-products (AGEs) produced during high-heat cooking, and pro-inflammatory activity.

Common examples include:

Bacon, sausages, and hot dogs
Ham, salami, pepperoni and other cured meats
Burgers and kebabs prepared out of processed meat
High-fat meat pies and tinned meats that contain a lot of additives

Refined Carbohydrates and Ultra-Processed Foods

Refined white flour, added sugar, and industrial oils are the ingredients that are used in the preparation of foods, which are low in the fibre content and lead to a rapid increase in blood sugar. The combination of many of these features and the evident dose-response correlation with type 2 diabetes have been observed in large population studies of ultra-processed products.

Typical examples include:

White rice, white pasta, and white bread
Pastries, cakes, biscuits and doughnuts
Packaged snacks (crisps, chocolate bars, cereal bars)
Sweetened breakfast cereals
Convenience food and fast-food meals

The Value of Iridology in Personalised Prevention

Iridology is a non-invasive and observational technique that examines the patterns, colours, and structures of the iris in order to understand the constitutional strengths and weaknesses of a person. The pancreas has a well-defined reflex zone on the traditional iridology chart (typically located in the right eye between roughly 7:15 and 7:45, though slight variations exist between charts). Knowledgeable iridologists, in the footsteps of such innovators as Dr Bernard Jensen, seek indications of pancreatic susceptibility including:

Lacunae (oval or crypt-like openings suggesting tissue weakness)
Radii solaris (spoke-like lines indicating nerve stress)
Yellowish or brownish discolouration
Pancreatic flattened collarette
General signs of poor nerve supply or lymphatic congestion

When they appear, the person might be more prone to blood-sugar disruption. The same food options that become a moderate risk to an individual with an excellent pancreatic zone may be quite problematic to an individual exhibiting an evident pancreatic stress condition visible in the iris.

Protective Foods to Prioritise

While some foods raise risk, many others actively support stable blood sugar, better insulin sensitivity, and lower inflammation. Emphasising whole, minimally processed plant foods is one of the most effective dietary strategies.

Helpful categories include:

Non-starchy vegetables (broccoli, spinach, kale, courgettes, peppers, cauliflower)
Lower-glycaemic fruits (berries, apples, pears, citrus)
Whole grains (oats, brown rice, quinoa, barley, buckwheat)
Legumes (lentils, chickpeas, black beans, kidney beans)
Nuts and seeds (almonds, walnuts, chia seeds, flaxseeds)
Healthy fats (avocado, extra-virgin olive oil, oily fish)

Practical Steps to Lower Your Risk

In case iridology shows the pancreatic weakness, dietary vigilance can be of particular help. Practical changes include:

Replace sugary drinks with plain water, herbal teas, or unsweetened infusions
Replace processed meat with plant-based proteins, eggs or fresh poultry/fish.
Choose whole grains and legumes over refined carbohydrates
Limit ultra-processed snacks and ready meals; prepare more meals from basic ingredients
Combine dietary changes with daily movement, stress reduction, and sufficient sleep

What really causes pre-diabetes? The answer goes far beyond sugar alone. In this video, we uncover the key factors that contribute to pre-diabetes, from food and drink choices to lifestyle habits and maintaining a healthy BMI.

Pre-diabetes happens when your blood sugar levels are higher than normal but not yet in the diabetes range – and it’s often a warning sign that you can take control of. Your daily choices make a huge difference:

Conclusion

Diabetes type 2 is a very lifestyle-specific disease that is frequently preventable or delayable. While sugary drinks, processed meats, refined carbohydrates, and ultra-processed foods stand out as the main dietary contributors to increased risk, iridology provides a unique window into whether your pancreas may be particularly sensitive to these foods. By recognising your individual iris signs and making informed adjustments to what you eat, you can take powerful, personalised steps toward lifelong blood-sugar balance.
