In general, losing weight by following a healthy, nutritious diet — such as the Mayo Clinic Diet — can reduce your risk of weight-related health problems, such as diabetes, heart disease, high blood pressure and sleep apnea. If you already have any of these conditions, they may be improved dramatically if you lose weight, regardless of the diet plan you follow.
Although red wine contains the chemical resveratrol and there is tentative evidence it may improve heart health, the evidence is unclear for those at high risk as of 2013. Grape skins naturally produce resveratrol in response to fungal infection, including exposure to yeast during fermentation. White wine generally contains lower levels of the chemical as it has minimal contact with grape skins during this process.
Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.
