Ravinteidenpuutteita, often translated as nutrient deficiencies, occur when an organism does not absorb or assimilate sufficient essential nutrients from its diet or environment. These nutrients are vital for growth, reproduction, and overall health. Deficiencies can affect a wide range of organisms, from plants and animals to humans.

In plants, nutrient deficiencies can manifest as stunted growth, yellowing leaves (chlorosis), poor flowering, or reduced fruit production. Common deficiencies include those of nitrogen, phosphorus, potassium, iron, and magnesium. These nutrients are critical for processes like photosynthesis, protein synthesis, and cell division.

For animals and humans, nutrient deficiencies can lead to various health problems. For example, iron deficiency causes anemia, while vitamin D deficiency can result in rickets or osteomalacia. Deficiencies in essential minerals like calcium or iodine can also have serious consequences. Symptoms vary widely depending on the specific nutrient lacking and can range from fatigue and weakened immune systems to severe developmental issues.

The causes of nutrient deficiencies are diverse. Inadequate dietary intake is a primary reason, but malabsorption issues, increased nutrient needs (e.g., during pregnancy or illness), or imbalances in nutrient absorption due to the presence of other substances can also contribute. Environmental factors, such as soil quality for plants, also play a significant role. Addressing nutrient deficiencies often involves dietary adjustments, supplementation, or improving environmental conditions.
