Micronutrient Highlights
Lamb Health Benefits
CLA — Highest of Any Common Meat
Lamb contains ~0.8g of conjugated linoleic acid (CLA) per 100g — the highest of any commonly consumed meat, approximately 2-3× more than beef. CLA is produced in the rumen of grass-eating animals. Research shows CLA reduces body fat, preserves lean mass during caloric restriction, and has anti-cancer properties. Grass-fed lamb has 2-3× more CLA than grain-fed.
Iron and Blood Health
Lamb provides 1.9mg of haem iron/100g — easily absorbed iron superior to plant iron for preventing and treating anaemia. Lamb also enhances absorption of non-haem iron from concurrent plant foods. In many cultures, lamb is considered restorative for people recovering from illness, blood loss, or pregnancy.
Omega-3 Fatty Acids — Grass-Fed Advantage
Grass-fed lamb has a significantly better omega-3:omega-6 ratio (~2:1) than grain-fed meat (~7:1). The omega-3s include ALA with some EPA and DHA from grass. This makes grass-fed lamb one of the better meat sources of anti-inflammatory fatty acids.
Selenium and Thyroid Health
Lamb provides 26.8µg selenium/100g (49% DV). New Zealand and Australian lamb is particularly high in selenium due to naturally selenium-rich soils. Selenium is critical for thyroid hormone conversion (T4 to T3), antioxidant function, and male fertility.
