Initially the reported effects may be negative. Upset stomach, anxiety, clinginess, dizziness, aches and pains and slight ill-temper have all been reported. Experience would suggest that these are good signs and precursors of a p ositive response. Reichelt recommends a trial period of three months. If it has not worked within that time it is unlikely to do so.

The effects in fully grown ind ividuals appear less impressive. It should also be noted that the withdrawal effects may also be more noticeable in small children and that these can sometimes be very marked.

The ideas are compatible with virtually all the accepted biological data on autism and are worthy of consideration. The dietary method must still be considered as experimental and no positive results can be promised or are claimed.
