Nutrition and lifestyle are the keys to longevity
A blog by Michael Butler
Articles and opinions for my family & friends about how I am living a healthier life informed by scientific research undertaken since being diagnosed with heart disease. Starting with the principle that each of us is biologically unique, everyone can use nutrition and lifestyle to achieve their greatest potential.

Reversing Type 2 Diabetes: Lessons from Dr. David Unwin
Want a feel-good story about health and longevity from a mainstream newspaper? Look no further. The Telegraph ran a great piece on how Dr. David Unwin is reversing Type 2 diabetes in his patients.
He lays out a simple and effective 6-point plan to get his patients off medication.
Vitamin B12 deficiency is a serious risk for vegans and vegetarians
Unsupplemented vegan diets do not contain vitamin B12 and have been described as a “dangerous experiment”.
This is a tragic story of what can go wrong.
The secret to living to 100 is high cholesterol?
There is more and more published evidence that cholesterol is not a health problem and LDL is not a good predictor of heart disease. Conversely, there is mounting evidence that hyperinsulinemia, insulin resistance, and chronic inflammation are predictive of metabolic dysfunction of which heart disease is a symptom.
This article summarises new publications I’ve found.
Children should not drink plant “milk”
Are plant-based drinks made from grains (e.g., oats) and nuts (e.g., almonds) good for our children? At least according to the British Government and the World Health Organisation, (WHO), the answer is an unequivocal “no”.
The biggest concerns are their high concentration of sugar, the unhealthy practice of consuming lots of sugar, and the danger of setting our children up for a lifetime of sugar-driven chronic diseases (e.g., obesity, diabetes and heart disease).
The Truth About Raw Milk - why it is safe and healthy
High-quality raw milk is no riskier than leafy greens, chicken, oysters, or pasteurised milk and it is associated with less asthma, allergies, eczema, and better gut health. The key to milk safety is rigorous on-farm hygiene, animal health, and regular testing - not heat treatment.
Sunday Telegraph - a misleading article on dietary fibre
We have to be careful when we read about nutrition in popular newspapers. This article is especially misleading about fibre in the human diet.
It misrepresents official dietary recommendations, seems oblivious to the harm to sensitive individuals caused by dietary fibre, and subtly promotes a one-size-fits-all highly processed plant-based diet.
Nutrient bioavailability - be careful with vitamin B12
Good health requires that we eat food containing nutrients we can access and use. Access and useability = bioavailability. Eating and drinking things with high theoretical nutrition content but zero bioavailability does us no good at all.
I’ve used this article to identify high bioavailability food.
Two Types of Raw Milk – One Is Safe and Healthy
Raw milk from an animal is a nutrient- and probiotic-rich natural food that can prevent allergies and asthma in children. The safe production of raw drinking milk requires a farmer’s attention to the health of his animals, on-farm hygiene, and routine and frequent safety testing.
Unfortunately, most milk produced on our farms is not safe for direct consumption and must be pasteurised first. This destroys the nutritional benefits of milk.
Sunlight protects against flu
If you're in the Southern Hemisphere presently (late summer heading into autumn), pay attention. Get out in the bright sunshine - it could help lower your risk of flu during the coming winter. For those of us in the Northern Hemisphere, where sunlight is scarce and flu circulates, stick with your vitamin D supplement and plan for safe, sun-soaked exposure in the summer and autumn.
Metabolic Wise - an interesting new way to get health information
Are you interested in the root causes of chronic disease and the emerging role of quantum biology in achieving metabolic healing?
This new AI-fueled searchable platform - Metabolic Wise - offers a new way to explore our individual health using an evidence-based approach.
Two people can eat the same diet and have radically different results
Have you ever thought that maybe you are special? Well, you are. Biologically, individuality is at the core of humanity. No two people are identical when it comes to hormones, organ size, and metabolites. Even “identical” twins are different. I describe in this article how to determine a proper individual diet, because there is no such thing as a single proper human diet.
If you consume more salt, you will live longer
How many times have you heard or read that dietary salt should be restricted? Population studies show that higher salt intake is linked to lower all-cause mortality and restricting it may do more harm than good.
Can rapeseed (Canola) oil cause obesity?
The evidence for starches and sugars as causes of obesity is pretty well established now (sadly, not as widely recognised as I’d like).
Similarly, seed oils are recognised as causing chronic inflammation. Not as well understood is the role of seed oils causing obesity. In this article I describe the temporal, geographic, animal, and mechanistic data and how they point to industrial seed oils as under-recognised drivers of obesity.
Malnutrition in Scottish children
A recent study by Food Standards Scotland has highlighted a lack of six essential micronutrients in Scottish children. The study also shows that existing deficiencies could be worsened if meat-based food and dairy intake are reduced. Deficiencies in the studied micronutrients are known to result in stunted growth and reduced cognition in children.
Micronutrient inadequacy in Europe - causes and solutions
From a recently published paper…dietary micronutrient deficiency in Europe is under-recognised and represents a threat to public health. Root causes include modern agricultural practices, poor dietary choices and lack of nutritional training among medical professionals.
Recovery is relatively straightforward but it’s an individual responsibility, there are no one-size-fits-all solutions.
All life on earth absorbs sunlight for energy…including humans
How important is sunlight for human health? I’ve come to believe that it’s as important as exercise or diet. Sunlight is used by the human body to support overall health and studies show that adequate sun exposure reduces the chance of disease and early death.
Wall Street Journal - Positive results of eliminating ultra-processed-food for one month
Two important lessons:
Teach kids to cook from scratch
Doing your best is all that’s required
Another article in the popular press, this time highlighting the health benefits of reducing industrially processed food and cooking from scratch.
It’s the starch that gets us – it’s simply sugar holding hands
If you’ve cut sugar from your diet and are still struggling with your weight, there’s a good chance starchy food is the issue. Starchy foods are rapidly converted to sugar. Our highly efficient digestive system breaks down bread, rice, pasta, and potatoes into glucose almost immediately, leading to unhealthy high blood sugar and insulin.
The Hidden Dangers of Modern Food: Understanding and Overcoming the High-Carbohydrate Trap
If you’re struggling with your weight the culprit may be modern food. It is chock-full of hidden sugars and starches which are addictive and cause all sorts of health issues. I broke free from the cycle of cravings and poor health by reducing bioavailable carbohydrates, eliminating processed foods, and focusing on nutrient-dense whole foods. In my opinion, these things hold the key to long-term wellness.
Scotland started basking in sunlight today
Scotland isn’t the first country that comes to mind when considering where to get an early Spring sun tan (and neither should it). However, today on March 11, for the first time in 2025, the sun has started giving us some UVB and potential to generate Vitamin D in our skin. It only lasts for about 30 minutes but as my boss used to say, “It’s time to dine on the delta”. Let the tanning and vitamin D production begin.
