Thiamin & The Paleo Diet

If you want to ensure you keep your body healthy, it is important to consume the right foods with plenty of the essential vitamins required for a healthy lifestyle. One of these vitamins is Thiamin, which is the water soluble vitamin B. The function of Thiamine in the body is to help our cells produce energy and it is imperative in order for our hearts, muscles and nervous system to function properly. Thiamin improves the contraction of muscles and also increased fertility in adults. It is also essential for children as it helps to improve the immune system from a very early age.

There are many notable signs that you may not be consuming enough Thiamin in your body. If your immune system is weak and you suffer from a lot of colds and flus, it may be due to a deficiency in Thiamin. As Thiamin is found in such a high number of different foods, it is quite rare to be deficient in this vitamin but it is quite common in alcoholics. It can also lead to a loss of weight and problems with the cardiovascular and nervous system.  If you are consuming too much Thiamin, it can also have negative effects on the body, although these may not be as noticeable as consuming too little. It is recommended that females have around 0.8mg of Thiamin, while males have 1mg. The recommended intake should be lower for children, so it is worth checking before you consume foods with Thiamin.

There are many foods on the Paleo diet which can help you to improve your intake of Thiamin. If you can manage to eat it, offal is a really good source of Thiamin and you can easily incorporate this into your daily meals if you don’t want to eat it as it comes. It is also found in high quantities in meat, such as beef and pork, which is why the Paleo diet is one of the healthiest to follow as it encourages the consumption of these food groups. It is always a good idea to ensure you are not consuming too much of this as otherwise, you won’t feel the full benefits.

If you enjoy eating your snacks on the Paleo diet, you will find that nuts and seeds act as a good source of Thiamin so consume these in moderation and you will soon notice the results. It is also found in a variety of fruits and vegetables, including asparagus, cauliflower and oranges. Eggs are also a good source of Thiamin and are a good choice to eat for your breakfast, as it will set you up for the rest of the day.

Thiamin is a source of vitamin B which is very sensitive to heat which means it can be easily destroyed during the cooking and preparation of food. A good method to use to get the most from it is to ensure you always cook your Thiamin rich foods for as little time as possible, as you will get the full benefits from it. There are other foods which you may want to add to your meals to absorb the Thiamin, including garlic and onions. These will also make them taste a lot better in the process.

As part of any healthy diet it is vital to consume a full range of the right nutrients and vitamins, which is why the Paleo diet is the healthiest to follow. If you are feeling lethargic and in need of a boost to your immune system, Thiamin will help you to feel much healthier and will improve your appearance.  You can also find Thiamin in supplements, but it is much better to try and get this from the foods you intake.

As long as you follow the Paleo diet strictly, you will be at your healthiest as you are consuming a wide range of different foods which offer a number of different benefits to the body. No matter what stage of life you start the Paleo diet, whether young or old, you will notice the difference in how you look and feel quite quickly. It is a great diet to ensure you are getting the right amount of vitamins and minerals from your foods. It is important to just keep an eye on your intake of each of the nutrients, so you are getting the maximum possible benefits from your food.

How Thiamin Supports Metabolic Health and Energy

One of the most essential roles of Thiamin is in the metabolism of carbohydrates. When you eat starchy vegetables or natural sugars found in fruit, your body relies on Thiamin to convert these foods into usable energy. Without enough of this B-vitamin, your metabolism may slow down, which can lead to fatigue, difficulty concentrating, or even mood swings.

For those following a Paleo diet, which typically includes fewer refined carbohydrates and more wholefood sources of energy, Thiamin plays a crucial role in supporting energy balance. It’s particularly important for people with physically demanding lifestyles or those trying to build muscle or improve athletic performance.

Best Paleo-Compatible Cooking Methods to Preserve Thiamin

As mentioned earlier, Thiamin is highly sensitive to heat and water. That means that certain cooking methods can destroy a significant portion of the vitamin before the food reaches your plate. To protect the nutrient content of your meals, consider the following cooking techniques:

• Steaming: A gentle method that avoids excessive water loss and minimises nutrient damage.
• Light sautéing: Cooking meats and vegetables briefly over medium heat with a healthy Paleo fat like coconut oil or beef tallow helps retain vitamins.
• Slow roasting at lower temperatures: This method can preserve more nutrients compared to high-heat frying or boiling.

By keeping cooking times short and avoiding high heat, you’ll give your body a better chance of absorbing the full spectrum of nutrients, including Thiamin.

Signs of Thiamin Deficiency to Watch For

Even with a varied Paleo diet, it’s possible to experience low Thiamin levels, especially if you’re under stress, recovering from illness, or consuming excessive coffee or tea, which can interfere with B-vitamin absorption. Watch out for signs such as:

• Unexplained tiredness or low stamina
• Muscle weakness, especially in the arms or legs
• Brain fog or poor memory
• Digestive issues like loss of appetite or nausea
• Cold hands or feet due to poor circulation

If you suspect your levels might be low, a visit to your healthcare provider can help confirm whether a deficiency is present and if supplementation might be needed.

Should You Supplement with Thiamin?

For most people on a well-balanced Paleo diet, supplementing with Thiamin isn’t necessary. However, if you’ve been under significant stress, have gut absorption issues, or follow a very restrictive eating pattern, it may be worth considering.

When choosing a supplement, opt for Thiamin mononitrate or benfotiamine, which are forms your body can absorb more efficiently. As always, it’s best to prioritise food sources first, with supplements as a backup if needed.

Easy Paleo Meals Rich in Thiamin

Incorporating more Thiamin into your Paleo diet doesn’t require complicated recipes. Here are a few simple, nutrient-rich ideas:

• Scrambled eggs with spinach and sunflower seeds: Quick, tasty and packed with Thiamin, iron and healthy fats.
• Beef stir-fry with garlic, onions and asparagus: A great weeknight dinner with a generous dose of B vitamins and minerals.
• Pork chops with cauliflower mash and steamed broccoli: High in Thiamin and perfect for batch cooking or meal prepping.
• Chicken liver pâté on vegetable slices: A classic nutrient-dense snack or lunch option full of bioavailable vitamins.

For extra variety, rotate your protein sources and experiment with herbs and spices to keep your meals exciting while still focusing on nutrient density.

Other B-Vitamins and Their Synergy with Thiamin

Thiamin doesn’t work alone. Like most B vitamins, it works best when consumed alongside its family members — B2 (riboflavin), B3 (niacin), B6, B12 and folate. These vitamins often share metabolic pathways, meaning your body relies on having a full complement to function efficiently.

Organ meats, eggs, leafy greens and seafood are all excellent sources of multiple B vitamins, making them staple foods for anyone serious about improving their energy, focus and immune resilience on the Paleo diet.

Supporting Children’s Health with Thiamin-Rich Paleo Foods

Getting enough Thiamin is especially important for growing kids. While they may turn up their noses at offal, you can still sneak nutrient-dense ingredients into everyday meals. Try adding puréed liver into burger mince, offering hard-boiled eggs as snacks, or sprinkling sunflower seeds into veggie-based lunchboxes.

For fussy eaters, try blending steamed cauliflower with a bit of coconut cream and garlic to make a creamy mash, or include chopped asparagus in homemade meatballs or omelettes. These small additions can go a long way in ensuring your child meets their daily Thiamin needs naturally.

Thiamin and the Paleo Lifestyle: Final Thoughts

By following the Paleo diet and focusing on high-quality, nutrient-dense foods, you’re already laying a strong foundation for optimal Thiamin intake. From energy production and neurological support to immune function and growth, this essential B-vitamin plays a role in nearly every system in your body.

Choosing whole foods like offal, pork, seeds and certain vegetables will help you meet your needs without the need for synthetic supplements. Combine this with smart cooking methods and food pairings, and your body will be well-equipped to thrive.
