A 2023 study suggests eating more prebiotics—compounds found in plant fiber that nourish healthy bacteria in the gut—may affect the brain's reward network in a way that helps people make healthier food choices.

An estimated 3% of adults ages 65 and older currently have dementia, and that proportion rises substantially as people age. The most convincing evidence for reducing one's risk relates to the basic foundations for an overall healthy lifestyle: aerobic exercise, a plant-based diet, and quality sleep. Aerobic exercise helps reduce the buildup of toxic proteins in the brain and improves blood flow, a plant-based diet can manage inflammation, and quality sleep helps the brain clear out harmful proteins.

A 2023 study suggests that regularly drinking sugar-sweetened beverages may increase women's risks of developing liver cancer or dying from chronic liver disease.

Food products advertised as being lower in sugar or sugar-free contain sugar substitutes. Sugar alcohol is another ingredient used as a sweetener in food products. But is sugar alcohol a better choice nutritionally than other sweeteners or natural sugar?

Dietary choices can influence weight, blood pressure, cholesterol levels, and blood sugar levels, all factors that can determine a person's risk for heart disease, heart attack, and stroke. Adopting certain eating habits can help manage these factors. These include reducing the intake of saturated fat and refined sugar that are included in many processed foods, eating more healthy monounsaturated and polyunsaturated fats, and following a plant-based diet like the Mediterranean or DASH diet.

Drinking excessive amounts of alcohol and feasting on foods high in natural compounds called purines may trigger gout in some people. Purine-rich foods that might be found on a holiday buffet include roast beef, brisket, lamb or pork chops, veal, chicken liver, turkey, trout, haddock, scallops, oysters, mussels, lobster, shrimp, or crab. While it's not necessary to completely shun alcohol and foods high in purines, doctors advise limiting them and sticking to a plant-based diet when possible, even during the holidays.

Despite statements like "promotes heart health" on the labels of fish oil supplements, multiple randomized trials show no evidence of heart-related benefits from using these products. In addition, manufacturing methods might make the products either useless or even harmful. The supplements do provide omega-3 fatty acids, but people can get these essential fats by eating two servings of fatty fish weekly or following a vegetarian diet rich in healthy oils, nuts, and seeds.

Products that encourage healthy eating or exercise can make good holiday gifts for family and friends. Examples include cooking gadgets (such as a food chopper or high-quality knife), a gift basket of fresh fruit or Mediterranean-inspired treats, or home workout equipment (such as dumbbells, resistance bands, or sports-related gear).
