Pea, potato, and pistachio milk? Supermarkets now sell multiple kinds of plant-based milks made from nuts, beans, grains, vegetables, or fruit. Before trying these, some people might like to know more about nutritional benefits and any other reasons to choose or avoid them.
Like most vitamins, B12 can’t be made by the body and must be gotten from food or supplements. A B12 deficiency –– which might stem from a vegan or vegetarian diet, or problems with absorption due to weight loss surgery or aging –– can seriously harm nerves, mood, thinking, energy, and more.

Brain fog, meaning slow or sluggish thinking, can occur under many different circumstances. In many cases, it is temporary and gets better on its own.

The CDC estimates that 70 million Americans suffer from chronic sleep problems. For some, melatonin is believed to be a safe treatment option because it is a hormone produced by our bodies. But evidence of its effectiveness is lacking, and inconsistent quality of product is a concern.
Sciatica refers to pain caused by the sciatic nerve that carries messages from the brain down the spinal cord to the legs. The pain of sciatica typically radiates down one side from the lower back into the leg, often below the knee. The most common cause is a bulging (“herniated”) disc in the lower back. Discs are tire-like structures that sit between the bones of the spine. If the outer rim of the disc tears, usually due to routine pressure on the lower back, the jelly-like inner material can come out and pinch or inflame the nearby nerve. Sciatica is most common in people 30 to 50.
There are two main types of herpes simplex virus (HSV) infections, HSV-1 and HSV-2. Generally speaking, HSV-1 is responsible for those annoying cold sores that can pop up during times of stress or lack of sleep. Genital sores are usually caused by HSV-2.

A study of Black adults living in the Atlanta area suggests that feeling rooted in community and socializing with neighbors may strongly contribute to better cardiovascular health, which might lower risk for heart attacks and strokes.
Direct-to-consumer (DTC) drug ads promoting treatments for arthritis, cancer, heartburn, psoriasis, flagging memory, and more are all everywhere you look. All too often, the information shared is incomplete, biased, or confusing––here’s what to watch out for and how to get the whole story when considering treatment options.
New parents might want to wait awhile before considering having another child, and breastfeeding prevents ovulation, so some people use it as a natural birth control method during the early months of an infant’s life. However, it’s effective only if a mother is breastfeeding frequently and an infant is receiving only breast milk as food.
The benefits of olive oil to help reduce the risk of heart disease are well-known, but a recent study showed that people who consumed the highest amount of olive oil daily had a lower overall risk of dying early, as well as lower risk of dying from heart disease, cancer, and other diseases.
