  • Red Inside Nutrient Rich Apples

    Redlove or Bloody Ploughman were bred from wild apples in their original home in Kazakhstan – many of these varieties are under threat due to forest clearance, showing how vital conservation work is for the future of our food. These apple trees have pink blossom. These apples are red inside and can contain up to twice the polyphenols and five times the healthy anthocyanins of regular light-fleshed apples.

    Once established, apples are one of the easiest fruits to grow, capable of kicking out decades of harvests for the 30 minutes it takes to plant one. Pick a sunny site with well-drained soil and make sure you keep plants evenly watered for their first year or so of growth. After that they will largely look after themselves.

Protein Digestibility-Corrected Amino Acid Score

The protein digestibility-corrected amino acid score (PDCAAS) has been adopted by FAO/WHO as the preferred method for the measurement of the protein value in human nutrition. 

PDCAAS = Amino Acid Score x Digestibility

The method is based on comparison of the concentration of the first limiting essential amino acid in the test protein with the concentration of that amino acid in a reference (scoring) pattern. This scoring pattern is derived from the essential amino acid requirements of the preschool-age child.

Although the principle of the PDCAAS method has been widely accepted, critical questions have been raised in the scientific community:

  1. the validity of the preschool-age child amino acid requirement values (more than 4 times greater than the EAA requirement for an adult),
  2. the validity of correction for fecal instead of ileal digestibility,
  3. the truncation of PDCAAS values to 100%.

The reference scoring pattern was based on studies performed more than 25 years ago on a limited number of 2-year-old children recovering from malnutrition.

According to the current official recommendations, a 2-year old child needs ~ 3x higher essential-to-non-essential amino acid ratio, and needs essential amino acids in different proportions than adult. Methionine/cysteine is the limiting essential amino acids for adults, and for children it is lysine or tryptophan.

The use of fecal digestibility overestimates the nutritional value of a protein because amino acid nitrogen entering the colon is lost for protein synthesis in the body and is, at least in part, excreted in urine as ammonia.
