This paper evaluates the impact of diet on risk factors for heart disease.

This blog post in Foodprint (part of US food advocacy group GRACE Communications) explores how food safety scares and recalls can cause food waste.

Two commentary pieces question the findings of the study “Association of Frequency of Organic Food Consumption With Cancer Risk”, which claims that higher organic food consumption is associated with a lower risk of cancer. The pieces point out that only two cancer types showed a statistically significant reduction in risk, and that the reduction in cancer risk only appeared to hold true for older women, not men, younger adults or people with a high overall quality of diet.

Wastewater canals used to irrigate urban agriculture in Burkina Faso may harbour dangerous microbes such as tuberculosis and genes that give microbes resistance to antibiotics, according to this research paper. The canals sampled by the researchers were designed to protect against flooding, but are used to water agricultural fields. The canals, which are not regularly cleaned, receive sludge, solid waste, wastewater, and effluent from a hospital, a market, houses and a slaughterhouse.

A paper argues that current definitions of ultra-processed foods are inconsistently applied. Furthermore, while higher consumption of ultra-processed foods is associated with higher sugar intake and lower fibre intake, the paper claims that intakes of fat, saturated fat and salt are not associated with ultra-processed food consumption. The paper questions the policy recommendation that ultra-processed foods should be avoided.

In a technical report, the American Academy of Pediatrics outlines the health concerns associated with several classes of food additives (including those unintentionally added to food, e.g. from packaging), including bisphenols, phthalates, perfluorinated compounds, artificial food colours, and nitrates and nitrites. The report notes that children may be particularly susceptible to the effects of these additives because of their lower body weight and because their metabolic systems are still developing.
