The right diet may help reduce your risk of Alzheimer’s disease and other types of dementia. Eating foods included in the DASH and Mediterranean diets helps maintain brain health by keeping blood flowing efficiently and reducing the damaging effects of inflammation. Some good foods to add to your diet are fatty fish, berries, plant oils, nuts, and coffee.

Probiotics are good bacteria that keep the gut healthy and help fight infections and inflammation. Some research suggests that certain probiotics help relieve symptoms of gut-related conditions like inflammatory bowel disease and irritable bowel syndrome. Fermented foods are the best sources of probiotics, such as yogurt, pickles, sauerkraut, and sourdough bread.

Sweeteners come in many varieties, including table sugar, honey, and maple syrup, high-fructose corn syrup and agave syrup. But regardless of type, from a biochemical and metabolic standpoint they are all virtually the same. Unfortunately, too much of any type is bad for one’s health.

A study published by JAMA Network Open found that people taking vitamin D supplements were less likely to have a cancer that spread from the original tumor site to another part of their body or one that proved fatal. However, this risk reduction was only seen in people who were at a normal weight, not those who were overweight or obese. The study did not find that people who took vitamin D were less likely to develop cancer over all compared with those who did not.

For decades, high intake of fat was thought to cause weight gain, heart disease, and maybe even cancer. The solution? Go low-fat, which often meant consuming more carbs and more sugar. But nutritionists now suggest people actually need adequate amounts of "good" unsaturated fat, and less "bad" saturated fat, for optimal health. Following popular heart-healthy diets, like the Mediterranean and MIND diets, and making simple dietary changes can help people get adequate amounts of good fats.

Some fermented foods contain probiotics, beneficial microorganisms that can live in your intestines. These microorganisms help you stay healthy, potentially improving your immune function and reducing damaging inflammation. Eating prebiotics—high-fiber foods that are a source of nutrition for these healthful microorganisms—is essential to help these beneficial microorganisms grow and thrive.

Studies show that people who regularly adhere to the Mediterranean diet lower their risk of cardiovascular disease, many types of cancer, and cognitive decline with age. But it’s possible that this healthy diet can be made even healthier. New research suggests that making the diet "greener" by boosting amounts of dark green vegetables, green tea, and plant proteins high in the micronutrients known as polyphenols offers even greater benefits.

Several habits can improve your heart health (and, as a side effect, may make you less vulnerable to infections like the flu or COVID-19). Focusing on a few of these is an excellent way to take care of your heart — and boost your overall health in the process.

A 2022 study found that vitamin D deficiency significantly increases the likelihood of age-related loss of muscle strength, known as dynapenia, a major risk factor for falls.

About 96 million Americans have prediabetes, defined by elevated blood sugar levels that are not high enough to qualify as diabetes. Risk factors include overweight or obesity, family history, and inactivity. People with prediabetes may have more infections and frequent urination or blurry vision after big meals. Lifestyle changes such as maintaining a healthy weight, exercising, eating healthy foods, drinking alcohol moderately, and not smoking may prevent prediabetes from progressing to diabetes.
