Sara Marin Berbell, a doctor and microbiota expert: "There are more important things than drinking milk for bone health."

It's always been said that drinking milk is good for its calcium , a mineral present in our bodies, especially in the teeth and bones. It's also found in other foods , such as some vegetables and nuts. Its benefits are numerous . For example, it's good "for muscles to move and nerves to transmit messages from the brain to different parts of the body," according to the U.S. National Institutes of Health. In Spain, and other countries, a glass of milk is a breakfast staple. But what other ways are there to provide our bodies with calcium? A doctor and expert in healthy habits has the answer.

Sara Marín Berbell is a doctor specializing in microbiota who has a following of over 600,000 on Instagram. In one of her videos, she talked about "five key nutritional tips for absorbing calcium," which we explain below. Take note!

The expert begins by saying that calcium is good because it helps "prevent osteoporosis and build muscle" and mentions some key mistakes and errors that people often make. The first is drinking three cups of coffee a day . She argues that this beverage causes "up to 6 milligrams of calcium to be eliminated through urine." Some people take supplements in the morning. For these people, Marín recommends taking them an hour after drinking coffee.

The next step to absorb calcium is to " soak legumes and grains ," a practice equally popular among many people in the kitchen. The main reason is that "they contain phytates that bind to calcium and hinder its absorption."

The third thing she mentions is vitamin D , a very important micronutrient for the body because, among other things, it helps prevent health problems such as certain types of cancer or respiratory conditions, as this doctor told 20minutos a while ago. Marína Berbell reveals that "most calcium depends on vitamin D for absorption," so eating foods like egg yolks is good. However, she highlights something important to note.

"If you take vitamin D and your microbiota and intestine are damaged , it will be of little use to you because calcium is absorbed in the intestine" and, as a consequence, he points out that, "if the intestine is inflamed , those walls are not able to absorb anything ."

The fifth point that stands out is the excessive consumption of corticosteroids , which she describes as "termites for your bones; they eat them away, leaving your bones empty and fragile." Therefore, and according to the information shared by the doctor and microbiota expert, this last point, as well as the others she highlighted, must be controlled.
