3 Changes Affecting Your Diet As You Age

December 19, 2025 —Our eating habits play a major role in how we age. Healthy eating habits lead to healthy aging, which is why we try to fill our plates with nutritious, wholesome food while limiting the amount of fat, salt and sugar that we consume. With that being said, did you know that your dietary requirements now are much different than they were just 10 years ago?

Over time, our bodies need less of certain nutrients and more of others. For example, a child less than one year old needs 27 mg of calcium per pound of body weight, whereas a typical adult woman needs just about one-fourth of that. The first step in implementing a healthy eating plans you get older is understanding what changes are happening to your body.

Physical Changes that Affect Your Diet 

1. Tastes buds become more desensitized

Refining your palate is one of the joys of growing older. When we are born, we have more than 10,000 taste buds in our mouth. As we age, however, the number of taste buds that we have decreases, and those that remain become less sensitive as the nerves tend to wear out over time. Because of this, many adults over 50 experience a decreased sense of taste. We tend to lose the sensitivity to salty and bitter tastes firsts, so many tend to over-salt their food to make up for that.

2. Metabolism slows down

Once you hit 40 years old, your metabolism starts declining and continues to do so as you grow older. So, if you continue to consume the same amount of calories that you did when you were younger, it will be very easy to gain weight—especially for those who aren’t very physically active.

The number of calories you need each day can be affected by many factors, including age, gender, and activity level. The necessary calories per day tend to decline with age, so it’s very important that the calories consumed by older adults are packed with nutrition. Below is a chart from the Academy of Nutrition and Dietetics regarding calorie intake per day for those 51 and over.

3. Appetite declines

Losing a few pounds without any effort may have been a luxury when you were younger, but now it could be a problem. As you age, your appetite may decline, and unexpected weight loss may be a side effect of that. One possible cause of decreased appetite is (as mentioned before) the desensitization of taste buds. Also, prescription medication and health problems can cause us to be less hungry. If you have recently lost weight without trying, please speak with your doctor to pinpoint the likely culprit.
