Dairy merchandise account for four–5% of the total PUFA intake in most European populations, whereas meat and meat products contribute one other 7–23% . The contribution of milk fat to omega-3 PUFA intake (approximated as consumption of α-linolenic acid) has been estimated at 5–16% , while meat contributes with 12–17% . The impact of exchanging organic for typical dairy products on omega-3 PUFA consumption while sustaining a relentless consumption has not been examined rigorously. From the intake and composition knowledge introduced right here, it may be estimated that selecting organic merchandise would increase the common dietary omega-three PUFA intake by 2.5–eight% (dairy) and by a much less certain 2.5–four% (meat).
A current preliminary estimate based mostly on FAO food supply data resulted in similar numbers . For certain population teams and fatty acids, these numbers could possibly be greater, and an increased omega-three PUFA consumption is mostly fascinating, as some subpopulations have a decrease-than-really helpful intake of omega-3 PUFA . However, overall, the effect of the animal production system on omega-3 PUFA intake is minor, and no specific health advantages can be derived. Furthermore, different dietary omega-three PUFA sources, specifically certain plant oils and fish, are available that carry extra benefits [204–206].
Far much less attention has been paid to the potential results of food processing. Processing may have an effect on the composition of foods and the bioavailability of food constituents. It is regulated and recognised that food additives are restricted for organic products in comparison with conventional merchandise. It is also recognised that the diploma of food processing may be of relevance to human health . In organic food processing, the processing ought to be accomplished “with care, preferably with the usage of organic, mechanical and bodily strategies” however there are no specific restrictions or guidelines.
- The only cumulative persistent danger assessment comparing organic and conventional merchandise recognized to us has been performed in Sweden.
- This signifies an no less than 70 instances lower publicity weighted by toxicity for a food regimen based mostly on organic meals.
- Overall, however, current systems for the certification and management of organic merchandise guarantee a low level of pesticide contamination as indicated by persistent and acute dangers above, although they nonetheless could be improved .
The existence of specific health benefits of ruminant trans fatty acids (as opposed to industrial trans fatty acids) is indicated by some studies but not strongly supported . Taking under consideration the truly consumed amounts of ruminant trans fatty acids, this is doubtless missing public health relevance .
Solvents can injury white blood cell function and decrease the immune system’s ability to withstand infections. Most of the research thought of in this review have investigated the results of agricultural production on product composition or health.
