Pregnancy: Conception – Maternity – Trimester
When supplements are necessary

When supplements are necessary

Why pregnancy sometimes changes the supplement equation For most adults, the preferred approach is simple: build nutrition around a varied diet and use supplements only when there is a clear reason. Pregnancy makes that principle more complicated because maternal stores, blood volume, tissue growth, and fetal development all increase demand for several nutrients. In that […]

Special diets and medical guidance

Special diets and medical guidance

What counts as a special diet in pregnancy A special diet is any eating pattern that substantially changes the usual balance, amount, timing, or type of foods for a specific reason. Some are chosen for personal, cultural, ethical, or religious reasons, such as vegetarian, vegan, halal, kosher, or fasting-based patterns. Others are therapeutic: gluten-free for […]

High-protein diets in pregnancy

High-protein diets in pregnancy

What counts as a high-protein diet in pregnancy? In everyday conversation, a “high-protein diet” can mean many things: adding extra servings of meat, using protein shakes, choosing specialty bars, or following a structured low-carbohydrate eating pattern that shifts calories toward protein. In pregnancy, those approaches are not equivalent. The key question is not whether protein […]

Keto and low-carb diets during pregnancy risks

Keto and low-carb diets during pregnancy risks

What keto and low-carb mean in pregnancy Keto is a very low-carbohydrate, high-fat eating pattern designed to push the body toward ketosis, a state in which the liver produces ketone bodies from fat. A low-carb diet is broader and may simply mean reducing refined starches and sugars without necessarily reaching sustained ketosis. That distinction matters […]

Cravings during pregnancy explained

Cravings during pregnancy explained

Why cravings happen Research suggests that pregnancy cravings are multifactorial, meaning they arise from several overlapping influences rather than one simple cause. Hormonal changes can alter olfaction and gustation, so foods may smell stronger, taste different, or seem newly appealing. Many pregnant people also notice heightened smell sensitivity, which can make previously neutral foods suddenly […]

Tracking food intake during pregnancy

Tracking food intake during pregnancy

Why tracking matters more than a single recall Pregnancy nutrition is dynamic. In research using repeated food records, daily intake varied markedly within the same pregnant participant and also between participants, which means a single day or a casual memory can miss important nutrient gaps or overestimate how well someone is eating. That matters because […]

Nutrient density vs calories

Nutrient density vs calories

What nutrient density actually means Nutrient density is usually defined as the amount of useful nutrients a food delivers relative to its calorie content. A nutrient-dense food provides a lot of nutrition for comparatively few calories. By contrast, an energy-dense food provides many calories in a small volume, often without a matching amount of vitamins, […]

Managing excessive weight gain

Managing excessive weight gain

Why weight gain can become excessive Pregnancy naturally changes body composition: blood volume expands, the uterus and breasts enlarge, the placenta develops, and the fetus grows. Because of that physiology, some increase on the scale is expected and healthy. Excessive gain means the pattern is rising above what is usually expected for the individual pregnancy, […]

Underweight and overweight pregnancy nutrition

Underweight and overweight pregnancy nutrition

Why weight status changes nutrition planning Prepregnancy weight status is commonly interpreted through body mass index, or BMI, which relates weight to height. BMI is imperfect because it does not directly measure body composition, metabolic health, muscle mass, edema, or social determinants of nutrition. Still, it remains useful at the population and clinical screening level […]

Weight gain diet planning

Weight gain diet planning

Start with individualized pregnancy weight-gain targets Weight gain diet planning in pregnancy begins with context. A person who enters pregnancy with a lower body mass index, a twin pregnancy, persistent nausea, gastrointestinal disease, food insecurity, or a high activity level may need a different strategy from someone with average pre-pregnancy weight and uncomplicated appetite. Your […]
