Flax seeds, often touted as a nutritional powerhouse, have been gaining widespread recognition in the world of health and wellness. Packed with essential nutrients, fibre, and beneficial fatty acids, these tiny seeds offer a plethora of health benefits.

In this blog, we’ll dive deep into the wonders of flax seeds, exploring their nutritional value, versatile uses, and how they can become a valuable addition to your daily diet.

What is Flaxseed?

Flaxseed, also recognized as flax or linseed, constitutes the seeds of the flax plant. Available in hues spanning reddish brown to light yellow (often called golden flaxseed), it can be ingested as whole seeds, ground powder, or flaxseed oil.

What is the Nutritional Profile of Flax Seeds?

Flaxseeds contain 534 calories in every 3.5 ounces (100 grams), equivalent to 55 calories per tablespoon (10 grams) of whole seeds.

Their composition comprises 42% fat, 29% carbohydrates, and 18% protein.

A single tablespoon (10 grams) of whole flax seeds provides the following nutritional values:

• Calories: 55
• Water content: 7%
• Protein: 1.9 grams
• Carbohydrates: 3 grams
• Sugar: 0.2 grams
• Dietary fibre: 2.8 grams
• Fat: 4.3 grams

Carbs and Fibre

Flax seeds are incredibly rich in fibre, with 95% of their 29% carb content being fibre.

Two tablespoons of flax seeds (20 grams) offer 6 grams of fibre, meeting 15–25% of the daily fibre intake for men and women.

This fibre is a blend of soluble fibre (20–40%) for blood sugar and cholesterol control, and insoluble fibre (60–80%) aiding in digestion.

Flax seeds, when mixed with water, form a thick mucilage, acting as a natural laxative, promoting regularity, preventing constipation, and lowering the risk of diabetes.

Protein

Flax seeds, with 18% protein, have a soybean-like amino acid profile but lack lysine, making them incomplete protein. Rich in heart and immune-boosting arginine and glutamine.

Fat

Flax seeds are rich in fat, with 1 tablespoon containing 4.3 grams, consisting of 73% polyunsaturated fatty acids, including omega-6 and ALA (alpha-linolenic acid) omega-3. ALA is essential and must be obtained from food as the body can’t produce it.

Flaxseed oil has the highest ALA content, followed by milled seeds, while whole seeds have the least. Flax seeds have a favourable omega-6 to omega-3 ratio, linked to lower chronic disease risk, but they contain less omega-3 than fish oils. Converting ALA to EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) is often inefficient.

Solin, a yellow variety of flax seeds, is less nutritious with a different oil profile and low omega-3 content.

What Vitamins, Minerals and Macronutrients Are in Flax Seeds?

Flax seeds serve as a valuable nutritional resource as they provide numerous vitamins and minerals, such as:

• Thiamine (vitamin B1): Essential for metabolism and nerve function.
• Copper: Crucial for growth, development, and bodily functions.
• Molybdenum: Abundant in seeds, grains, and legumes, serving as an essential trace mineral.
• Magnesium: Occurs in high amounts in grains, seeds, nuts, and green leafy vegetables, playing a vital role in the body.
• Phosphorus: Typically found in protein-rich foods, contributing to bone health and tissue maintenance.

Flax seeds are also rich in numerous beneficial plant components, like:

• Antioxidants: p-Coumaric acid and Ferulic acid, which combat oxidative stress.
• Cyanogenic Glycosides: Can form thiocyanates, potentially affecting thyroid function.
• Phytosterols: Similar to cholesterol, aiding in cholesterol reduction.
• Lignans: Abundant in flax seeds, serving as potent antioxidants and phytoestrogens.

The multiple health benefits of lignans are:

• Phytoestrogens: Mimic oestrogen, reducing heart disease and metabolic syndrome risk.
• Cardiovascular support: Lower fat and glucose levels in the blood.
• Blood pressure regulation: Helps reduce blood pressure.
• Arterial health: Combats oxidative stress and inflammation in arteries.
• Cancer inhibition: Slows the growth of hormone-sensitive cancers like breast, uterus, and prostate cancer.

How Can Flax Seeds Be Used in Cooking and Baking? 

Flax seeds offer versatility in cooking and baking, providing both flavour and nutrition. Here’s how they can be used:

• Flaxseed meal: Substitute for eggs by mixing 1 tbsp flaxseed meal with 3 tbsp water.
• Whole flax seeds: Sprinkle on baked goods for a nutty, crunchy topping.
• Flaxseed oil: Ideal for salad dressings, drizzling on vegetables, or blending into smoothies.
• Smoothies and cereal: Add ground flax seeds for nutrition and texture.
• Baking: Replace some flour with ground flax seeds (up to 25%) in muffins, pancakes, and bread.
• Energy bars: Boost nutritional value and binding properties in homemade bars.
• Thickener: Use flaxseed to naturally thicken soups, stews, and sauces.

Store flax seeds properly to maintain freshness and nutritional benefits. Grinding them just before use is recommended. Incorporating flax seeds into your meals enhances fibre and omega-3 intake.

What is the Impact of Flax Seeds on Heart Health, Digestion, and Cholesterol Levels?

Flax seeds offer various health benefits across heart health, digestion, and cholesterol levels:

Heart Health

• Rich in Omega-3 Fatty Acids (ALA) that reduce inflammation.
• May reduce the risk of heart disease and blood pressure.

Digestion

• High in dietary fibre, aiding bowel regularity.
• Mucilage content soothes the digestive tract and helps with IBS (irritable bowel syndrome)
• Reduces the risk of diverticulitis.

Cholesterol Levels

• Potentially lowers “bad” LDL cholesterol.
• The soluble fibre and lignans contribute to this effect.

Ground flax seeds aid digestion. Consult a healthcare professional if you have health conditions or take medications. Include them in a balanced diet for health benefits.

Do Flax Seeds Help in Reducing Weight? 

Flax seeds, rich in soluble fibre, aid weight loss by reducing hunger and cravings.

Controlled studies found that incorporating flax seeds into diets helped overweight individuals shed an average of 2.2 pounds (1 kg).

Longer studies and daily consumption of over 30 grams showed even more significant weight loss effects.
