Hypercholesterolaemia treated by soybean protein diet.

Area of Science:

• Pediatrics
• Nutrition Science
• Cardiovascular Health

Background:

• Familial hypercholesterolaemia (FH) is a genetic disorder causing severely elevated cholesterol levels from birth.
• Managing FH in children presents challenges due to psychological difficulties with drug treatments and limited efficacy of standard low-fat diets.
• Early intervention is crucial to mitigate cardiovascular risks associated with high cholesterol.

Purpose of the Study:

• To evaluate the efficacy of a textured soybean protein-based diet in reducing cholesterol levels in children with FH.
• To assess the long-term adherence and maintenance of cholesterol-lowering effects of the soybean diet.
• To explore a non-pharmacological, dietary alternative for managing pediatric hypercholesterolaemia.

Main Methods:

• A cohort of 16 children diagnosed with familial hypercholesterolaemia participated in the study.
• Following an initial stabilization period on a controlled low-lipid, low-cholesterol diet, children were switched to a textured soybean protein diet.
• Dietary intervention lasted for eight weeks, with follow-up assessments to monitor cholesterol levels, triglyceridaemia, and high-density lipoprotein cholesterol.

Main Results:

• The soybean protein diet resulted in a significant reduction in total cholesterol, averaging -21.8% from baseline after eight weeks.
• Triglyceridaemia and high-density lipoprotein cholesterol showed minimal changes, with only a slight increase in HDL at the end of treatment.
• Over one year, more than half of the participants maintained adherence, with sustained cholesterol-lowering effects.

Conclusions:

• Textured soybean protein-based diets can effectively lower total cholesterol in children with familial hypercholesterolaemia.
• This dietary approach provides a viable and potentially more acceptable alternative to drug therapy or conventional low-lipid diets for pediatric FH.
• The soybean diet supports normal growth and offers a promising strategy for long-term management of hypercholesterolaemia in children.
