"Both seeds are rich in protein, calcium, fibre, and various vitamins and minerals, making them nutritious additions to your diet. But before diving into which seed might be better for weight loss, it is important to know the health benefits they offer," says dietitian Ekta Singhwal.

What are the benefits of eating flax seeds?

Flax seeds shine with several impressive health benefits:

• Anti-inflammatory properties: Flax seeds are an excellent source of omega-3 fatty acids, which help combat inflammation in the body and may lower the risk of inflammatory diseases, such as arthritis, as per the Journal of Food Science and Technology.
• Gut health: Rich in dietary fibre, flaxseeds promote gut health. When consumed, the fibre ferments in the large intestine, resulting in the production of beneficial short-chain fatty acids, as per the journal Healthcare.
• Anti-diabetic effect: "Regular consumption of flaxseeds can enhance insulin sensitivity, making them a potentially beneficial choice for individuals managing diabetes", says the expert.
• Anti-cancer properties: The antioxidants found in flax seeds may help reduce tumour growth and decrease the risk of hormone-related cancers, thanks to their lignan content, as per the MD Anderson Cancer Centre.

What are the benefits of chia seeds?

Chia seeds also offer a variety of health perks:

• Heart health: Chia seeds contain alpha-linolenic acid, which may lower LDL (“bad”) cholesterol levels, contributing to a healthier heart, according to the Journal of Current Research in Food Science.
• Skin benefits: "Chia seed oil is known to help manage conditions like eczema, promoting skin hydration and reducing itching", says the dietitian.
• Antioxidant effects: Rich in antioxidants such as quercetin and kaempferol, chia seeds help reduce inflammation and protect the body from oxidative stress, as reported in the journal Pharmaceuticals.
• Gut health: Similar to flax seeds, chia seeds support gut health by promoting beneficial bacteria and reducing constipation, thanks to their high fibre content.

Flax seeds or chia seeds: What seed is best for weight loss?

Both chia and flax seeds come with a few warnings regarding their consumption:

• Raw consumption caution: It’s not recommended to eat these seeds raw, as they can contain compounds like hydrogen cyanide and other heavy metals, which can be toxic in high amounts.
• Roasting for safety: "The best way to enjoy these seeds is by roasting them. Heat can help eliminate harmful substances, making the seeds safe for consumption", states the dietitian.
• Ground flax seeds: Ground flax seeds can be an excellent addition to a weight loss drink. Mix them with hot water, and you will have a satiating beverage that supports digestion.
