A member of the mackerel family, tuna is rich in healthy oils and immunity-boosting minerals.
Tuna contains vitamin E and selenium, which are needed for the production of disease-fighting antibodies, and many B vitamins, which enhance energy. Like oily fish, it has high levels of omega-3 fatty acids, a family of essential fatty acids, a family of essential fatty acids that can help prevent heart disease, cancer and depression. Omega-3s also play a role in balancing the immune system, helping to reduce allergic reactions. They are also anti-inflammatory, calming conditions such as rheumatoid arthritis and eczema. The omega-3s stimulates production of a hormone called leptin that controls the appetite.
Always choose fresh rather than canned tuna because it loses it’s omega-3 fatty acids during the canning process but it is still good diet food – just make sure it has no added oil, salt or other undesirable additives.
The best choices are albacore, skipjack and yellowfin tuna.
