Lectins & The Paleo Diet

No matter what type of food we eat, we can’t avoid Lectins as they are in absolutely everything we consume on a daily basis. Lectins are proteins which are found in animals, plants and our very own bodies and they have a number of functions which offer a means of protection to us. They can help to control the protein levels in humans but are also protective for plants as well. It is also thought that the right Lectins can also be beneficial in acting as a defense mechanism against serious illnesses, such as cancer.

Lectins can be useful for the body, but they can also be damaging, depending on the type of Lectin. There are many different types of Lectins found in different foods, so it is important to ensure we are taking in the right ones which offer the best benefits to our bodies. The function of Lectins also depend a lot of the individual and how sensitive their digestive system is as to how they will react to specific types of Lectins. The foods which contain particularly harmful Lectins include grains and legumes, which is why they are forbidden on the Paleo diet. These foods have the potential to destroy all of the good nutrients and vitamins in your body which makes you more susceptible to suffering from serious illnesses, such as heart disease and obesity.

If you consume the wrong Lectins and your body rejects these, it will also start rejecting all the good foods you eat, which means they will be of no benefit to you whatsoever. In order for the body to function effectively, it is essential that we absorb the right minerals and nutrients, which is why it is important to avoid legumes and grains on the Paleo diet. There are plenty of foods which contain Lectins which are good for our body and act as a way of protecting it, so it is important to be aware of the right foods to eat in order to get the most out of our bodies and feel as healthy as we can.

The Paleo Diet Lectins Grains Gluten Wheat-min

Gluten is one of the harmful Lectins that can cause a lot of problems with the digestive system, which is why many people who have particularly sensitive guts have to eat gluten-free foods. Gluten-free foods are becoming standard in supermarkets and restaurants these days, which shows how much of a problem gluten can be. Gluten is often found in wheat products including the high sugar and high fat foods we are advised to avoid as part of the Paleo diet. These harmful Lectins can attack the body and cause a lot of damage to the intestine which results in a leaking gut, not to mention a lot of pain. Bad Lectins can completely destroy the immune system, leading to issues such as extreme weight loss, diarrhea and sickness. It can also cause more serious illnesses, such as diabetes.

There are ways of reducing the presence of bad Lectins in legumes and grains, including soaking and soaking them, but it won’t completely destroy them so it is much better to avoid them completely. The Paleo diet encourages the avoidance of these food groups for a reason; they are not good for the body.

Nuts and seeds also contain Lectins but again, they are only beneficial to the body if you eat these in moderation. There are many of us who can’t stop eating nuts when we start, so if this sounds like you, it is best to just avoid eating them. There are plenty of nutritious foods on the Paleo diet which will offer good Lectins as well as plenty of other important vitamins and nutrients which are essential for a healthy body.

Overall, Lectins won’t pose problems for most people, but there are a number of people who have particularly sensitive guts, which means the bad Lectins, such as those found in grains and legumes can end up causing issues with the digestive system. Sufferers of a sensitive gut are not always born with this; it can develop over a number of years and become a worse problem in later life. It is better to completely avoid these, which is why the Paleo diet is such a beneficial one to follow.

How Lectins Interact with the Gut Lining

Lectins have the ability to bind to carbohydrates and glycoproteins on the surface of the intestinal lining. In people with sensitive digestive systems, this can interfere with nutrient absorption and may contribute to intestinal permeability, commonly referred to as “leaky gut.” This condition allows partially digested food particles and other compounds to pass into the bloodstream, potentially triggering an immune response.

Even for those without immediate symptoms, low-level inflammation triggered by harmful lectins may contribute to fatigue, joint pain, or skin issues. The Paleo diet helps reduce this risk by focusing on whole foods that are low in or free from harmful lectins, such as leafy greens, grass-fed meats, and properly prepared root vegetables.

Lectin Sensitivity and Autoimmune Conditions

There is growing research suggesting that lectins may play a role in exacerbating autoimmune diseases. In genetically predisposed individuals, lectins may confuse the immune system by mimicking proteins found in the body’s own tissues. This process, known as molecular mimicry, may contribute to conditions like rheumatoid arthritis, Hashimoto’s thyroiditis, and coeliac disease.

By reducing dietary lectin exposure through a Paleo framework, many people with autoimmune symptoms report fewer flare-ups and improved energy. While this is not a one-size-fits-all solution, it offers a compelling starting point for those exploring nutritional therapy as part of their health journey.

Low-Lectin Paleo Food Swaps

Avoiding high-lectin foods doesn’t mean limiting variety. There are many nutrient-dense Paleo-friendly options that are naturally low in lectins. Consider these swaps in your everyday meals:

  • Swap lentils and chickpeas for roast pumpkin or cauliflower mash in salads and bowls
  • Use coconut flour or almond flour instead of wheat-based flours for baking and coating
  • Replace soy products with coconut aminos or homemade sauces using garlic, ginger, and apple cider vinegar
  • Choose cassava or sweet potato instead of grains like rice or corn

These alternatives help reduce inflammation while supporting gut health and keeping meals delicious and satisfying.

Nightshades and Their Lectin Content

While grains and legumes are the most well-known sources of problematic lectins, another food group to approach with caution is the nightshade family. Tomatoes, capsicum, potatoes, and eggplants all contain lectins that may irritate the digestive tract in sensitive individuals. Although not all Paleo followers need to avoid nightshades, those with autoimmune conditions or chronic gut issues may benefit from reducing or eliminating them for a trial period.

A helpful approach is to keep a food journal and document symptoms. This can provide valuable insight into whether nightshades or other borderline foods are contributing to discomfort.

Can Soaking or Sprouting Reduce Lectins?

Traditional food preparation methods such as soaking, sprouting, and fermenting can reduce the lectin content in certain plant foods. These techniques were commonly used by ancient cultures before modern processing methods took over. However, while these practices do help reduce some anti-nutrients, they rarely eliminate lectins entirely.

For those committed to a strict Paleo approach, it is simpler to avoid lectin-rich foods altogether rather than relying on preparation techniques. That said, those who tolerate lectins better may find that occasional sprouted nuts or fermented vegetables are acceptable in moderation.

The Role of Resistant Starch and Gut Bacteria

One lesser-known aspect of lectin sensitivity involves the health of your gut microbiome. A diverse and balanced population of gut bacteria may help protect the intestinal lining and reduce the negative impact of low levels of dietary lectins. Resistant starches such as green banana flour and cooked then cooled sweet potato can nourish beneficial bacteria and support a healthier gut barrier.

Incorporating a variety of fibrous vegetables, fermented foods (if tolerated), and occasional resistant starch can help maintain microbial diversity. However, it is still wise to limit high-lectin foods that overwhelm or damage the gut environment.

Signs You Might Be Lectin Sensitive

While not everyone needs to eliminate lectins entirely, certain symptoms may suggest you could benefit from a trial reduction. Common signs of lectin sensitivity include:

  • Bloating or gas after meals
  • Unexplained fatigue or brain fog
  • Joint stiffness or chronic pain
  • Skin issues like eczema or rashes
  • Irregular digestion, including constipation or diarrhoea

If these symptoms are familiar, consider a 30-day Paleo-style elimination focused on low-lectin foods. This gives your body a chance to reset, and reintroducing foods one at a time can help identify your personal thresholds.

Are All Lectins Bad?

It is important to acknowledge that not all lectins are harmful. Some types, especially those found in safe vegetables like carrots, celery, or lettuce, are not known to cause irritation. In fact, many of these foods are beneficial and support healthy digestion and immunity.

The key lies in avoiding large quantities of the more reactive lectins, particularly those in improperly cooked or processed grains, legumes, and certain nightshades. By being selective and informed, you can maintain a balanced diet that maximises benefit while minimising risk.

Finding Your Optimal Balance

The Paleo diet is inherently low in harmful lectins, which is why it serves as an ideal template for those looking to improve their digestion and overall health. Whether you go fully lectin-free or simply reduce your exposure, it is about finding what works best for your individual body.

Listen to your symptoms, keep meals simple and nutrient-dense, and give yourself permission to adapt your approach as your body changes. Over time, you may find that you tolerate certain foods better or learn new ways to support your gut health naturally.

Everyone’s tolerance to lectins is different, but by tuning into your body's signals and focusing on whole, Paleo-approved foods, you can take control of your health from the inside out. Do you thrive on a low-lectin lifestyle? Share your experience in the comments below.

Phytic Acid & The Paleo Diet nuts soaking-min

Phytic Acid & The Paleo Diet

There are many benefits to adhering to the Paleo diet as a means of getting rid of body fat and helping to reduce the likelihood of a number of illnesses. One of the benefits of the Paleo diet is that it can help to reduce phytic acid intake. It obliterates foods which are full of phytic acid in favour of those which contain low levels such as fruits and vegetables.

Phytic acid is highly obstructive as it has the ability to stop essential minerals from being absorbed. These minerals include magnesium, iron and calcium, which are important as part of any healthy diet. Phytic acid binds itself to these minerals and as our bodies can’t break them down, it can result in a number of health issues. There are many people who consume high levels of cereal, as they believe that this is beneficial to the health but in fact these are one of the main culprits of phytic acid. As a result, they can actually prove to be quite damaging to the health. As our ancestors substituted cereals for other healthy foods such as vegetables and fruits, it was a much healthier way of living which is why the Paleo diet is the best one to follow.

The health issues which can result from a diet which is high in phytic acid include PMS, stomach cramps and skin problems, which can be very detrimental for our quality of life. There are many people who also suffer from anaemia, which is caused by iron deficiency and it is believed that this could be caused through a high phytic acid diet. The Paleo diet promotes an eating plan which minimises the intake of foods which contain phytic acid, in order to promote a healthier lifestyle.

The right diet is the most important way of maintaining good health and more often than not, most of us will reach for the painkillers when we feel unwell, rather than getting to the root cause of the problem.   There are certain foods which are extremely high in phytic acid and these are best to completely stay clear of when following the Paleo diet. The most common of these are grains and legumes. These foods can be replaced with fruits, vegetables and nuts and seeds, which are full of minerals and antioxidants.

Phytic Acid and the Paleo Diet – nuts, soaking

Nuts and seeds are quite high offenders when it comes to levels of phytic acid but you can minimise these by soaking them in purified water. Nuts are full of health benefits, but should only be eaten in moderation; otherwise they will be counter productive.  As far back as our ancestors, people were soaking their nuts and seeds and as the reason behind the Paleo diet is to go back to our roots, it is a ritual we should bear in mind when trying to reduce our intake of phytic acid. The best way to achieve this is to soak the nuts in purified water, cover them and add sea salt. You should then give them a rinse and drain them, before putting them in the oven at the lowest possible temperature. It may seem like a bit of a lengthy process, but the benefits to help are worth taking these steps.

In order to really get the balance between the right nutrients and lowering levels of phytic acid, it is worth educating ourselves on the content of our foods so we are more aware of whether or not they will be detrimental to our health. There are plenty of nutritious foods to eat as part of the Paleo diet, which will result in noticeable changes to your health and fitness levels. Good combinations of the right foods, together with an exercise plan will not only improve your appearance, but will also help you to enjoy a longer and more fulfilling lifestyle.

If you find any of the foods on the Paleo diet are bland, you can always season them with apple cider vinegar as this is a tasty substitute to high calorie mayonnaise and it offers lots of health benefits. It can take a while to get used to following the diet, but it can be really beneficial to the body and appearance. It will soon become a way of life and reducing phytic acid levels is just one of the many benefits of following this simple but effective diet.

How Phytic Acid Affects Nutrient Absorption

Phytic acid, also known as phytate when in salt form, is often found in the outer layer of seeds, nuts, legumes, and grains. While it serves a protective function in plants, its impact on human health is more complex. Once ingested, phytic acid binds to positively charged minerals like zinc, calcium, magnesium, and iron — forming insoluble complexes that the body cannot absorb. This effectively reduces the bioavailability of these essential minerals, even when your diet includes an otherwise adequate intake.

Over time, consistent consumption of foods high in phytic acid can contribute to deficiencies, particularly for individuals who are already at risk of low mineral levels. This is especially concerning for women (due to menstrual blood loss and pregnancy), children, athletes, and those recovering from illness. The Paleo diet naturally avoids high-phytate foods by steering clear of legumes and grains, making it a practical approach to maintaining mineral balance without the need for supplementation.

Modern Misconceptions About ‘Health Foods’

Marketing has led many people to believe that breakfast cereals, wholegrain bread, and granola bars are healthy daily staples. Yet, these products often contain high levels of phytic acid due to the processing of wheat, oats, soy, or other legumes. While fortified with synthetic vitamins and minerals, the phytic acid content can still impair absorption, particularly in the case of non-heme iron — the type found in plant foods.

When viewed through a Paleo lens, these so-called health foods lose their appeal. By focusing on bioavailable nutrients from natural sources — such as leafy greens, animal proteins, and fermented or properly prepared nuts — the Paleo diet offers a far more effective way to nourish the body without interfering with digestion or mineral uptake.

Traditional Practices for Reducing Phytic Acid

Long before modern science understood the implications of phytic acid, traditional cultures developed food preparation techniques that naturally reduced its levels. Soaking, sprouting, fermenting, and slow-cooking were commonplace, especially for legumes and grains. These methods activate phytase, an enzyme that breaks down phytate and helps release the bound minerals.

While Paleo largely avoids grains and legumes, nuts and seeds are still included — though in moderation. Applying the same ancestral wisdom of soaking and low-temperature dehydrating allows you to enjoy these foods without the same anti-nutrient load. If you regularly consume almonds, walnuts, sunflower seeds or pumpkin seeds, it’s worth adopting a soaking routine as part of your food prep rituals.

Meal Planning for Low Phytic Acid Living

Creating balanced Paleo meals that avoid phytic acid and support optimal nutrition is easier than it sounds. Here are some simple ideas:

  • Breakfast: Scrambled eggs with sautéed kale and mushrooms, plus half an avocado
  • Lunch: Grilled chicken breast over a salad of rocket, cucumber, beetroot, and olive oil dressing
  • Dinner: Baked salmon with roasted sweet potato and steamed broccoli
  • Snack: A small handful of soaked and dehydrated cashews or macadamias

These meals are rich in micronutrients, contain minimal to no phytic acid, and offer plenty of fibre and healthy fats — all essential for sustained energy and long-term wellness.

The Long-Term Benefits of Reducing Phytic Acid

In addition to improving nutrient absorption, reducing dietary phytic acid can lead to noticeable improvements in energy, mood, skin clarity, and digestion. Many people who switch to Paleo report a reduction in bloating, fatigue, and cravings, especially when high-phytate foods are eliminated. Over time, the cumulative benefits of improved mineral status can lead to stronger immunity, better hormonal balance, and increased bone density.

Furthermore, minimising anti-nutrients like phytates can be particularly important for those with gut conditions such as IBS, SIBO, or leaky gut syndrome. By removing dietary irritants, the gut lining has a chance to heal and absorb nutrients more effectively — often leading to fewer symptoms and better overall resilience.

Final Thoughts on Phytic Acid and the Paleo Diet

Reducing phytic acid is just one of many advantages to living Paleo. By emphasising whole, nutrient-dense foods that don’t compete with your body’s ability to absorb essential minerals, you’re building a strong foundation for lifelong health. It’s not about restriction — it’s about making food choices that align with how our bodies evolved to thrive.

If you’re just beginning your Paleo journey, don’t stress about perfection. Focus first on removing the obvious offenders — cereals, bread, legumes — and get comfortable with preparing whole meals from scratch. Over time, you can add in practices like soaking nuts and rotating seasonal produce for even better results.
