Why the Paleo Diet Is Not Safe for Long-Term Health

The Paleo diet promises a return to the eating patterns of our hunter-gatherer ancestors—lots of meat, vegetables, fruit, nuts, and seeds, with strict avoidance of grains, legumes, dairy, and processed foods. While it may help some people eliminate common food triggers, the Paleo diet falls short as a long-term health solution.

In fact, many people on Paleo experience constipation, fatigue, inflammation, and nutrient imbalances after the initial “honeymoon phase.” This article reveals the hidden dangers of Paleo and why the ASTR Diet, developed by Dr. Joseph Jacobs, offers a safer, more complete healing approach.

What Is the Paleo Diet?

The Paleo diet focuses on whole foods that humans supposedly evolved to eat before agriculture. It allows:

• Meat, poultry, fish

• Eggs

• Vegetables and fruit

• Nuts and seeds

It strictly excludes:

• Grains (even gluten-free)

• Legumes (beans, lentils, peas)

• Dairy

• Processed foods and refined sugar

What’s the Problem with Paleo?

While the Paleo diet removes many inflammatory foods (like refined sugar and seed oils), it also eliminates important healing foods and fails to address environmental toxins, gut health, and hormonal balance—key factors in chronic disease.

---

1. It Lacks Gut-Supportive Fiber and Resistant Starch

By excluding legumes, oats, and many root vegetables, Paleo eliminates key prebiotic fibers that feed beneficial gut bacteria.

• A low-fiber diet leads to gut dysbiosis, constipation, and increased intestinal permeability (leaky gut)

• Fiber fermentation creates short-chain fatty acids like butyrate, which lower inflammation and support colon health

• Long-term low fiber intake weakens immune function and increases chronic disease risk

📚 Sonnenburg & Bäckhed, 2016; De Filippo et al., 2010

---

2. It Can Be High in Inflammatory Saturated Fat and Animal Protein

Many Paleo followers rely heavily on red meat, bacon, and eggs for protein and fat.

• Excess saturated fat and heme iron from red meat increase inflammation and oxidative stress

• Cooking methods like grilling or frying can produce harmful compounds such as heterocyclic amines (HCAs)

• Diets high in animal protein are linked to increased cancer risk, especially when fiber intake is low

📚 Mazidi et al., 2021; Pan et al., 2012

---

3. It Ignores Environmental Toxins

The Paleo diet focuses on which foods to eat, but not how those foods are raised, sourced, or packaged.

• Conventionally raised meat may contain antibiotics, hormones, and pesticide residues

• Non-organic produce and packaged “Paleo snacks” often contain hidden preservatives or plastic residues

• These toxins disrupt hormones, damage the gut, and burden the liver

📚 Heindel et al., 2017; Muncke et al., 2020

---

4. It Fails to Address Hormonal Balance and Detoxification

The Paleo diet overlooks critical aspects of healing, such as:

• Supporting liver detox pathways through cruciferous vegetables, bitter greens, and fasting

• Balancing estrogen and cortisol with adaptogenic foods and fiber

• Replenishing micronutrients that are lost through chronic stress or inflammation

Without these elements, chronic symptoms often return—even if you’re “eating clean.”

---

5. It’s Restrictive, Stressful, and Often Unsustainable

Many people struggle to stay on Paleo long term due to its restrictions on beans, rice, oats, and dairy-free substitutes. This can lead to:

• Frustration, fatigue, and burnout

• Nutrient deficiencies (including calcium, magnesium, folate, and B vitamins)

• Disordered eating patterns and guilt around “non-Paleo” foods
