One of the things I liked so much when I started researching about Paleo, was the ease and simplicity. The books basically tell you to eat a simple diet, of the natural foods we've evolved to eat. I found there really was nothing confusing or contentious. As well as reading the Paleo and Evolutionary health books – I read everything else I could find on nutrition. There is a book for every fad diet imaginable, with completely conflicting and confusing advice. Some of the diets just seem downright complicated to follow and devoid of any logic.
One of the best selling diet books in Australia at the moment is about the “DASH Diet”, so I couldn't resist taking a look. I've noticed the newer fad diets seem to be more closely resembling Paleo, so I always hold out hope that books like this will be about Paleo, but with a different name.
DASH stands for “Dietary Approaches to Stop Hypertension” and is aimed at those suffering from High Blood Pressure, though it also has a significant focus on weight loss. I had high hopes when I picked up the book – but it quickly became apparent that the book is based on the flawed food pyramid. The plan recommends a diet high in fruit, low-fat dairy and whole grains. It also advises avoiding processed food and limiting (not eliminating) sugar.
While the DASH diet is based on studies, these studies only compared three different nutritional plans. Unfortunately they don’t give the specific meal plans for each of the diets in the study, just the macro nutrient profiles – and some of the micro nutrient profiles. From this it’s apparent the DASH diet had 10% less fat than the other diets (taken entirely as Saturated fat), with the 10% added onto the protein and carbohydrate consumed. Without knowing exactly what they ate, this is rather meaningless. Cheap, commercial chocolate is high in saturated fat – as is butter – they clearly aren't equal, yet this study doesn't allow us to differentiate.
The book is full of un-Paleo recommendations such as only eating whole-grain bread, avoiding coconut oil, trimming all visible fat off meat and only eating low-fat dairy.
I'm sure someone coming from a highly processed SAD diet would (initially) see benefits on a DASH diet – but only because they had cut out processed foods, sugars and therefore reduced their carbohydrate intake. It saddens me that unwell people follow this diet in good faith – when it isn't based on good science – and certainly doesn't seem optimal.
What do you make of the DASH diet and the other fad diets out there?
Why DASH Appeals to the Mainstream
One reason the DASH diet has gained mainstream popularity is its alignment with conventional health messaging. It embraces the familiar low-fat mantra, encourages whole grains, and maintains dairy as a staple. To someone accustomed to following government-endorsed food guidelines, DASH feels like a modest and manageable shift rather than a radical overhaul. But therein lies the problem — it's not radical enough. For someone with serious metabolic issues, obesity, or autoimmune conditions, a middle-of-the-road approach like DASH may not go far enough to initiate meaningful healing.
What the Science Really Shows
The DASH diet is often praised for its backing by scientific studies, particularly those showing reduced blood pressure in participants. But context is everything. These studies often compare DASH to the Standard American Diet (SAD), which is packed with seed oils, refined grains, and sugary snacks. Any whole food-based plan — including Paleo — will outperform the SAD. So while DASH may reduce blood pressure, it doesn’t necessarily mean it’s the optimal diet for long-term health. Additionally, many studies fail to isolate individual dietary components, making it hard to determine whether the benefits come from reducing sugar, increasing vegetables, or simply eating less processed food.
Dairy, Grains and Low-Fat Myths
The DASH diet’s reliance on low-fat dairy, whole grains, and trimming all fat from meats reveals its roots in outdated nutritional dogma. From a Paleo perspective, these recommendations are problematic. Dairy is one of the most common allergens and inflammatory foods — not ideal for those with compromised gut health or autoimmune conditions. Whole grains, while less processed than white flour, still contain anti-nutrients like phytic acid and lectins that can irritate the gut lining. And fat — particularly saturated fat from healthy sources — is essential for hormone production, brain health, and nutrient absorption. Demonising fat is not only misguided, it’s dangerous.
The Paleo Advantage
In contrast, the Paleo approach eliminates the grey areas. It encourages eating foods our ancestors evolved to consume: high-quality animal protein, natural fats, vegetables, and some fruit. There’s no place for industrial seed oils, refined grains, or processed sugars. While DASH restricts certain foods and focuses on portion control, Paleo focuses on food quality, satiety, and nourishment. Instead of counting calories or obsessing over macros, Paleo encourages intuitive eating by choosing nutrient-dense, whole foods. This approach naturally regulates appetite and supports metabolic health.
What About Blood Pressure?
Critics of Paleo often ask how it affects blood pressure, given its inclusion of red meat and higher fat intake. However, several studies and anecdotal reports show that those switching from a high-carb, processed-food diet to Paleo often experience improved cardiovascular markers, including better blood pressure. This is likely due to reduced inflammation, weight loss, better insulin sensitivity, and increased intake of potassium-rich vegetables. Eliminating sugar and processed carbohydrates alone can have a profound impact on blood pressure — without the need to rely on low-fat yoghurt and wholemeal toast.
Psychological Simplicity
Another overlooked advantage of Paleo is how straightforward it is. The DASH diet includes specific daily servings and food group quotas — three servings of dairy, eight of whole grains, and so on — which can feel like a chore to track. Paleo eliminates this by sticking to a clear rule: if it's a whole food, eat it. If it comes in a box or has ingredients you can’t pronounce, don’t. This binary approach reduces decision fatigue, simplifies meal planning, and makes it easier to sustain in the long term.
A Better Way Forward
It’s easy to understand the appeal of a medically endorsed, evidence-based diet like DASH. But it’s important to ask deeper questions about the quality of that evidence, the context in which it was gathered, and how it applies to individuals with diverse metabolic needs. For those who have tried DASH, or other moderate diets, and still struggle with symptoms or weight, Paleo may offer a more effective and sustainable path.
There’s no need to count calories or limit salt when you’re eating real food. A steak with roast veggies, a frittata with avocado, or a handful of macadamias won’t send your blood pressure soaring. In fact, many people find their blood pressure improves naturally when they eat more mindfully and ditch the processed food altogether.
What to Watch Out For
It’s worth noting that not all versions of Paleo are the same. Some people lean too heavily on Paleo treats and recreations — think coconut flour pancakes and almond butter brownies — which can still spike insulin and reinforce poor eating habits. Just like DASH, Paleo is most effective when it focuses on real food. That means plenty of vegetables, ethically raised meats, good fats, and minimal natural sweeteners.
Final Thoughts
Ultimately, any dietary change should support your unique health goals. While DASH may suit someone who’s only just begun to move away from processed food, Paleo offers a more comprehensive and ancestral template for lifelong health. If you’re tired of fads, conflicting advice, and restrictive meal plans, it might be time to return to the basics. Whole food, movement, sleep, and sunshine — simple, timeless, and powerful.
