Introduction
In this modern sedentary lifestyle, obesity has become a main concern, which has led many health related problems. People are trying exercises, diet, and protein supplements for weight loss. However, when it comes to weight management and health concern, two nutrient-rich superfoods always steal the spotlight, they are-chia seeds (Salvia hispanica L.) and flaxseeds (Linum usitatissimum L.). Both are small seeds , but they are packed with high fiber, protein, omega-3 fatty acids, and antioxidants. However, the question remains-which one is better for weight loss? Let us compare their nutritional value, affordability, availability, and sustainability one by one.
Nutritional Comparison for Weight Loss
- Fiber and Satiety
Chia Seeds: Two tablespoons of chia seeds (28 g) contains 10 g of fiber. When the seeds are soaked in water, they form water soluble gel which slows the digestion, keeps fuller for longer time, and also it reduces sudden blood sugar increase.
Flaxseeds: If we consider flaxseeds, about 28 g of seeds contains approximately 8 g with both soluble and insoluble forms. This aids in satiety. Also promoting smooth digestion and gut health.
Winner for fullness: Chia seeds
Winner for digestion and gut health: Flaxseeds
- Omega-3 Fatty Acids and Fat Metabolism
Omega-3 Fatty Acids and Fat Metabolism
Flax seeds
Flaxseeds are richer in alpha-linolenic acid (ALA) than chia seeds. Flaxseeds are also the powerhouse of lignans, which are unique phytoestrogens associated with fat regulation and hormonal balance, especially in women. This makes flax seeds more interesting for women who are aiming to manage their weight in their midlife.
Chia seeds
Chia seeds are also rich in alpha-linolenic acid (ALA), which provides plant-origin omega-3 fatty acids that may influence fat metabolism. Past studies suggest that chia seed consumption can moderately reduce visceral fat along with a calorie-deficient diet.
Winner for fat metabolism: Flaxseeds
- Calories and Energy Balance
When it comes to the calories and energy balance, both seeds are calorie-dense, about 120–140 kcal per 2 tablespoons. However, their high fiber and protein slow digestion, making them more weight-loss-friendly than calorie-dense processed items like chips and sweets.
- The gel-forming property of chia seeds may help to keep us fuller for a longer time.
- But this gel-forming factor is lacking in Flax seeds. However, its nutty taste blends well in smoothies and baked goods.
Ease of Use
Chia Seeds: Can be eaten raw, soaked, or added directly to meals; no grinding is needed.
Flaxseeds: Must be ground for nutrients to be absorbed; whole seeds often pass undigested.
