 Topics this week range between how drinking affects the brain in specific periods of a lifetime, the harmful effects of obesity the longer it lasts in younger adults, and also diet modifications, including cheese and wine intake that have a positive impact on the cognitive function of older adults. Here are the highlights:
Drinking linked to a decline in brain health from cradle to grave Harm prevention policies must take the long view, say experts The evidence for the harmful effects of alcohol on brain health is compelling, but now experts have pinpointed three key time periods in life when the effects of alcohol are likely to be at their greatest.

The research, which looked at households in low- and middle-income countries, showed growing their own food helped mothers to prevent stunting, wasting and underweight in their children. Their children's food was more varied, meaning they had access to different classes of food nutrients.

Both omega-3s are found in fish oil.

Source: PLOS Obesity impairs immune cell function, accelerates tumor growth High-fat diet allows cancer cells to outcompete immune cells for fuel A new study in mice finds that a high-fat diet allows cancer cells to outcompete immune cells for fuel, impairing immune function and accelerating tumor growth. Cancer cells do so by rewiring their metabolisms to increase fat consumption. Blocking this rewiring enhances anti-tumor immunity. The findings suggest new strategies to target cancer metabolism and improve immunotherapies. Source: Harvard Medical School Diet modifications - including more wine and cheese - may help reduce cognitive decline The foods we eat may have a direct impact on our cognitive acuity in our later years, according to new research. The study is the first of its kind to connect specific foods with cognitive decline. The findings show cheese protected against age-related cognitive problems and red wine was related to improvements in cognitive function.
