什么是有机食品?
Many shoppers assume organic products are more nutritious 和 safer to eat, but these perceptions are based more on hype than hard science.
“Some supporters of organic food production promote it as being ‘better’ without any supporting science,佩妮·克里斯-埃瑟顿说, Ph.D., a registered dietitian 和 Distinguished Professor of Nutrition at the Pennsylvania State University’s College of Health 和 Human Development. “在营养和安全方面, organic food is no different than foods produced by other contemporary food production practices.”
在2020年的系统评估中, researchers reviewed a wide range of interventional 和 observational studies. The current evidence does not indicate a definitive statement on the health benefits of consuming organic foods.
Some consumers buy organic produce to reduce their exposure to residue from pesticides. 然而, studies comparing pesticide- with non pesticide-grown foods have found that neither is significantly safer than the other. The AHA recommends everyone eat a variety of colorful fruits 和 vegetables, regardless of if they are organic or nonorganic. Both types provide important nutrients 和 fiber for a healthy eating plan.
有机是什么意思??
有机 is a labeling term that indicates the food (or other agricultural product) has been produced according to the 美国农业部有机标准(链接在新窗口中打开). The USDA has four categories for labeling organic products:
- 100%的有机 — for products made with 100%的有机 ingredients.
- 有机 — for products with at least 95% organic ingredients.
- 采用有机原料制成 — denoting a minimum of 70% organic ingredients. The USDA 有机 Seal cannot be used on the product, 和 it cannot be represented as organic. Only up to three ingredients can be represented as organic.
- Multi-ingredient产品 — these have less than 70% percent certified organic content. They would fall under the “specific organic ingredients,” 和 don’t need to be certified. These products cannot display the USDA 有机 Seal or use the word organic on the principal display panel. They can list certified organic ingredients in the ingredient list.
增加的成本=更好的口味?
平均而言，.S. organic farms have higher production costs than conventional farms. 有机 products have a higher price tag than their nonorganic counterparts because of the increased cost of complying with USDA st和ards 和 a decreased yield per acre, 稍微说. Some consumers are happy to shell out the extra money because, they say organic tastes better. 然而, no evidence indicates organically grown food tastes better, although it’s usually fresher when purchased because it doesn’t contain preservatives 和 therefore must be brought to market sooner.
