All the properties of flaxseeds for your body

Lower cholesterol, protect your heart, and support weight management… all in a single ingredient? Yes – it’s possible with flaxseeds.

This superfood is a healthy addition packed with benefits that’s worth knowing about. Let’s explore all its benefits and see exactly how its nutrients work to look after you – especially when they’re part of a mindful diet.

1 Helps with weight management

Flaxseeds help lose weight as they are rich in dietary fats. Healthy fats, together with soluble fibre (abundant in flax and which forms a gel in the stomach), are the nutrients that most delay gastric emptying.

This means food stays longer in your stomach and small intestine. This process:

? Research has shown that high-fat diets can help with weight loss and maintaining muscle mass, so you burn more calories than fat.

2 Helps control cholesterol

Flaxseeds are an excellent ally for controlling cholesterol and weight thanks to their high fibre content.

Their soluble fibre forms a gel in the intestine that helps eliminate excess cholesterol, while lignans and omega-3 improve the lipid profile.

94% of flaxseeds’ composition comes from fibre, a nutrient that helps with digestion and blood sugar regulation.

?An RCT by J. Nur showed that ground flaxseed reduces total and LDL cholesterol in patients with PAD, and has additional LDL-lowering properties when used together with SMM.

3 Reduces menopause symptoms

Flaxseeds are an excellent natural option to relieve troublesome menopause symptoms such as hot flushes, night sweats, mood swings and vaginal dryness, thanks to their high lignan content.

Lignans are phytoestrogens, plant compounds with a structure similar to human oestrogen. When consumed, they act as hormonal modulators, helping to balance oestrogen levels in the body, which tend to drop sharply during menopause. This helps to:

? In a study with post-menopausal women, 40 g of flaxseed per day helped reduce menopause symptoms and improved glucose and insulin levels, although its effect on cholesterol was less compared to hormone therapy.

4 Low glycaemic index

Flaxseeds have a low glycaemic index (GI), which means they don’t cause sharp spikes in blood sugar after eating. This is mainly due to their high content of soluble fibre (mucilage) and healthy fats, which slow digestion and carbohydrate absorption.

? Studies have shown that adding ground flax to meals significantly reduces the post-prandial glycaemic response, making it an ideal food for people with type 2 diabetes, insulin resistance or metabolic syndrome.

5 Improves nutrient absorption

Whole flaxseeds have a hard outer shell that the human digestive system can’t fully break down, which means that many of their nutrients – especially omega-3 fatty acids (ALA), lignans and soluble fibre – pass through without being absorbed.

However, when ground, these bioactive compounds are released, allowing for greater bioavailability.

? A study showed that consuming ground flax significantly increases blood levels of ALA and lignans compared with whole seeds, reinforcing its role in cardiovascular protection and metabolic control.

Is it better to take whole or ground seeds?

1 Whole

✅ Ideal use: add a crunchy texture to salads, yoghurts or cereals.

⚠️ Limitation: their hard shell makes digestion more difficult, so their nutrients are only partially absorbed.

? Recommendation: use them mainly for their contribution to flavour and texture, not as your main nutritional source.

2 Ground

✨ Maximum benefit: grinding breaks the shell, releasing key nutrients (omega-3, soluble fibre, proteins).

?️ Versatility: easy to add to smoothies, breads, biscuits or as a thickener.

⭐ Generally, it’s recommended to consume ground flaxseeds because they allow for better digestion and absorption of beneficial compounds such as omega-3 fatty acids and lignans. Whole flaxseeds can pass through the digestive system without breaking down completely, which reduces their nutritional benefits.

Contraindications and possible side effects

Although flaxseeds are generally safe, excessive consumption may cause digestive discomfort such as bloating or diarrhoea due to their high fibre content.

People with bowel obstruction problems or specific allergies should avoid them. It’s always advisable to check with a professional before incorporating them regularly, especially if you are pregnant, breastfeeding or taking medication.
