Trump Administration to Relax Nutrition Rules in Schools

The Trump administration has received much criticism after announcing plans to ease back on healthy eating standards in schools, an initiative previously championed by Michelle Obama.

The new proposals will allow more pizza, meat, and potatoes and less fresh fruits and vegetables and whole grains to be served in schools. The Department of Agriculture says that the new rules would allow schools more flexibility and meet the children’s demands.

However, critics say that the new rules have been influenced by school districts and food lobbying groups such as the potato industry due to financial reasons.

Childhood obesity is a major problem in the US, with one-fifth of children and adolescents classified as ‘obese’.

The proposed rules, which classify potato and pasta as vegetables, would allow children to choose foods high in calories, saturated fat, and salt in place of healthy, balanced school meals.

New Research Shows that We Still Don’t Know What Microplastics Are

A newly published study from Brunel University has found that people are still largely unfamiliar with microplastics and how they relate to everyday domestic plastic usage.

Microplastics (small plastic particles less than 5mm in size) can enter our bodies through ingestion, inhalation, and dermal contact. Ingestion largely occurs through microplastics entering our natural environment and ending up in our water systems via a number of routes (i.e. surface run-off). Once microplastics enter our water systems, where they remain, they can end up in our drinking water – both tap and bottled.

Despite microplastics receiving widespread coverage, people seem unaware of how microplastics originate and find it difficult to make the link between their own plastic usage and the microplastics which end up in the ocean.

A recent study by researchers from The University of Newcastle in Australia found that the average person consumes about 5g of plastic every week from water. The implications for human health remain unclear, but scientists say that it’s unlikely to be good news.

Reducing single-use plastic (i.e. using a refillable water bottle) and supporting a ban on microplastic-containing products are two ways to reduce the amounts of microplastics reaching our oceans.

New Clinical Trial Reveals Walnuts Could Boost Heart and Gut Health

A new study published in the Journal of Nutrition suggests consuming walnuts enriches certain gut bacteria, which is associated with improvements in blood pressure and cholesterol. Researchers believe this could be due to the unique combination of bioactive compounds, fatty acids and dietary fibre found in walnuts.

The study included 42 overweight or obese individuals at risk of heart disease. Participants followed a typical American diet for two weeks and were then randomly assigned to a six-week diet that replaced some saturated fat with walnuts, a vegetable oil blend with the same fatty acid profile as walnuts, or a vegetable oil blend that was higher in omega-9 oleic acid.

Individuals who consumed walnuts and the vegetable oil with the same fatty acid profile as walnuts showed positive shifts in gut bacteria compared to the average American diet.

Those following the walnut diet only had high amounts of a beneficial species of bacteria which is associated with cardiovascular benefits.
