The Claim
Grain feeding in yaks increases the proportion of monounsaturated and saturated fatty acids in their fat tissue while decreasing the proportion of n-3 polyunsaturated fatty acids, resulting in an n-6/n-3 fatty acid ratio of 5.13.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When yaks are fed grain instead of grass, their fat contains more monounsaturated and saturated fats, less n-3 polyunsaturated fats, and the ratio of n-6 to n-3 fats becomes 5.13.
See the scientific wording
Grain feeding in yaks increases the proportion of monounsaturated and saturated fatty acids while decreasing n-3 polyunsaturated fatty acids, resulting in an n-6/n-3 ratio of 5.13, which is higher than the recommended dietary ratio for human health.
When yaks eat grain, their bodies get more energy than they need, which turns on genes that make more saturated and monounsaturated fats and turn off pathways that break down or make omega-3 fats. This causes more of the unhealthy fats to build up in their muscles and less of the healthy omega-3 fats to be produced or kept.
What the research says
1 studyWhen yaks eat grain instead of grass, their meat gets fattier and more tender, but it also has more of the unhealthy fats and less of the healthy omega-3 fats — just like the claim says.
