Preparing for a Fast: Medical Guidance on Vitamin and Mineral Health
Individuals who may be prone to deficiencies in essential vitamins and minerals should seek medical advice before starting any prolonged fasting plan. This guidance comes from a specialist in endocrinology and nutrition who stressed the importance of a pre-fasting medical review for those considering a fast in North America as well as elsewhere. The goal is to ensure there are no underlying health issues that could be worsened by fasting and to determine whether any supportive measures are needed before beginning a fast.
For people at higher risk of nutrient gaps — including those with excess weight, gastrointestinal conditions, a history of donating blood, chronic blood loss, older age, pregnancy, or other relevant health factors — a consultation with a healthcare professional is advised prior to deciding whether to fast. medical professionals can evaluate current nutrient status and decide if any additional investigations or supplements are required before beginning a fasting regimen [Citation: Nearmedic clinic guidance, presented for informational purposes].
It is important to remember that during periods of fasting, dietary restrictions may reduce intake of animal products, including eggs and dairy. This can raise the potential for certain nutrient shortfalls if dietary planning is not careful.
The recommendation is to broaden the diet for individuals who have not previously shown problems with iron or other trace elements. Increasing dietary variety helps support overall nutrient balance during a fast.
Practical guidance emphasizes a diet rich in iron as well as other macro- and micronutrients. Practical steps include consuming a wide array of vegetables and fruits, with a goal of daily intake across colors and types, aiming for a broad spectrum of phytonutrients. Whole grains and legumes should be staple components, and a varied plate helps sustain energy and micronutrient stores throughout the fasting period [Citation: Endocrinology and nutrition guidelines, general advisory].
In related market developments, there is ongoing discussion about changes in consumer food choices during dietary shifts, including trends in fat-free products and other dietary substitutes in the region [Citation: Market trend observations].
