Ronny Allan’s Newsletter covering May 2026

Newsletters, Patient AdvocacyAdvanced neuroendocrine cancer, Fat soluble vitamins, Pancreatic NET (PanNET), Small intestine NET (SI NET), Water soluble vitamins

Just back from holiday thus why the late publication! Summary of May 2026 on RonnyAllan.NET I think the main story of May is similar to March and April which was a strong blog performance. Other key targets met were the two main primary NET types (small intestine and pancreas) and one not so common(thymus) have finally been added to my Spotlight series and a batch of updates to my vitamin series. You will note blogs are coming through in a different format? This was partly due to people with iPhones complaining about 'jumpy screens'. That was resolved the issue but I am…

This blog provides general educational information only. It does not offer medical advice, diagnosis, or treatment. Patients should always consult their clinical team for personalised guidance. Introduction: What Are Fat‑Soluble Vitamins? Fat‑soluble vitamins — A, D, E and K — are nutrients that can only be absorbed when dietary fat is digested properly. They rely on bile acids, pancreatic enzymes, and a healthy small intestine (especially the jejunum and ileum) to form tiny droplets called micelles, which carry these vitamins across the gut wall. Unlike water‑soluble vitamins, they are stored in the liver and fatty tissues, so deficiencies develop…

An ENETS Position Statement on nutritional support in Neuroendocrine Neoplasms

Diet and NutritionBile acid malabsorption, Diet, Digestive enzymes, Fat malabsorption, Fat soluble vitamins, Nutrition, Pancreatic enzyme replacement therapy (PERT), Vitamin A, Vitamin ADEK, Vitamin B12, Vitamin D

I've written many times about Nutrition and NETs - clearly it should say NENs (Neuroendocrine Neoplasms) as the issues also extend to Neuroendocrine Carcinomas. I was helped in the early days by my friend and 'nutrition for NET' mentor Tara Whyand, at the time, probably the top NET Nutrition Registered Dietitian in the world. Perhaps she still is. Much of what Tara said and wrote, and what I emphasised, particularly in my blog and my patient group, was that much of this was not fully integrated into NEN patient care as part of a multi disciplinary approach. Many attempts have…

Neuroendocrine Cancer Nutrition Series Article 2 – Gastrointestinal Malabsorption is the second article in the Neuroendocrine Cancer Nutrition series. In the first article, I focused on Vitamin and Mineral deficiency risks for patients and there is a big overlap with the subject of Gastrointestinal Malabsorption. Those who remember the content will have spotted the risks pertaining to the inability to absorb particular vitamins and minerals. This comes under the general heading of Malabsorption and in Neuroendocrine Cancer patients, this can be caused or exacerbated by one or more of a number of factors relating to their condition. It's also worth pointing out that…

If you want to strike up a friendly conversion with a Brit, ask him or her about the weather - we're really famous for our weather conversations and they normally focus on rain or clouds! However, despite the famous British 'reserve' and 'stiff upper lip', they also frequently talk about being 'under the weather', a phrase meaning slightly unwell or in low spirits.I find myself smiling at some of the conversations I hear in medical establishment waiting rooms, particularly the potentially long wait for blood tests. Here, conversations bypass the weather and focus on being under the weather! I thought…
