\u201eKdy\u017e cvi\u010d\u00edte, spalujete cukr, ale v\u011bt\u0161ina lid\u00ed to po cvi\u010den\u00ed nadm\u011brn\u011b kompenzuje sladk\u00fdmi odm\u011bnami,\u201c<\/span><\/em>\u00a0\u0159\u00edk\u00e1 a zmrzlinu po tr\u00e9ninku ozna\u010duje za kontraproduktivn\u00ed.<\/span><\/p>\n

P\u0159ehodnocen\u00ed cukru ve 21. stolet\u00ed<\/span><\/h2>\n

Posun od plo\u0161n\u00e9 fobie z cukru k c\u00edlen\u00e9 v\u00fd\u017eiv\u011b zalo\u017een\u00e9 na vyh\u00fdb\u00e1n\u00ed se skryt\u00e9 frukt\u00f3ze a konzumov\u00e1n\u00ed celozrnn\u00fdch potravin je kl\u00ed\u010dov\u00fd pro omezen\u00ed epidemi\u00ed, jako je cukrovka.<\/span><\/p>\n

Jeho poselstv\u00ed je jasn\u00e9: pochopen\u00ed v\u011bdy o cukrech nen\u00ed jen \u0161kola; je to z\u00e1chrann\u00e9 lano.<\/span><\/p>\n

Jeliko\u017e zpracovan\u00e9 potraviny jsou sou\u010d\u00e1st\u00ed ka\u017edodenn\u00edho \u017eivota, osvojen\u00ed si uv\u011bdom\u011bl\u00fdch stravovac\u00edch n\u00e1vyk\u016f pom\u016f\u017ee uv\u011bdomit si nebezpe\u010d\u00ed cukru a ochr\u00e1nit budouc\u00ed generace.<\/span><\/p>\n
