Daily consumption of food products enriched with carob fibre shows beneficial effects on human blood lipid profile and may be effective in prevention and treatment of hypercholesterolemia.

The lipid-lowering effect of a carob pulp preparation rich in insoluble dietary fiber and polyphenols was investigated in a noncomparative, open-label pilot study. Over 8 weeks, 47 volunteers with moderate hypercholesterolemia (total cholesterol 232-302 mg/dL) consumed 15 g of carob per day in three products (breakfast cereal, fruit muesli bar, powdered drink) as a supplement to their regular diet. After 4 weeks, reductions of 7.1% in mean total cholesterol and 10.6% in LDL cholesterol were noted; respective decreases after 6 weeks were 7.8% and 12.2% (all P<.001). HDL cholesterol and triglyceride levels remained unchanged. Overall compliance was good. Only 3 volunteers (6%) reported a sensation of fullness, which led to 2 of the 3 dropouts. The carob preparation may have value in the dietary treatment of hypercholesterolemia.

This 6-month study evaluated a probiotic multivitamin preparation in 42 adult men and women suffering from stress or exhaustion. The preparation was taken daily with breakfast. A psychological-neurologic questionnaire assessed psycho-organic, central vegetative, and somatic discomforts, and a validated list of adjectives was used to indicate the effect of therapy. At the end of the study, an overall 40.7% improvement in stress was noted, representing significant improvements of 17.4% in positive conditions and of 23.3% in negative conditions (both P<.001). In addition, decreases of 29% in the frequency of infections and of 91% in gastrointestinal discomforts, both established indicators of stress, were recorded. The preparation was well tolerated. This probiotic multivitamin is suitable for reducing stress or exhaustion, or both, as well as for improving the immune system, specifically gastrointestinal health.

The lipid-lowering effect of a soy-based protein supplement was evaluated in an 8-week randomized, placebo-controlled trial in patients with hypercholesterolemia. A total of 117 patients (63 men and 54 women) received soy protein, either 15 or 25 g/d or placebo. In the active treatment groups low-density lipoprotein cholesterol levels decreased significantly by 5.9% and 1.1% respectively, but increased by 3.6% with placebo. Total serum cholesterol and apolipoprotein B levels changed significantly in a similar manner. High-density lipoprotein cholesterol, triglycerides, homocysteine, folic acid, and vitamin B12 levels did not change significantly compared with baseline in any of the study groups. All preparations were well tolerated. Soy protein 25 g/d was twice as effective as 15 g/d. In conclusion, soy protein supplementation may effectively reduce serum cholesterol levels and therefore is likely to diminish the risk for cardiovascular disease.

In this pilot study, 43 patients with rheumatoid arthritis ingested 1 g of cod liver oil (one capsule) daily for 3 months. Decreases occurred in morning stiffness (52.4%; P<10(-3)), painful (42.7%) and swollen (40%) joints (P= 10(-3) each), and pain intensity (67.5%). Ratings of "good" or "very good" were awarded by 68% of the patients for efficacy and by 95% for tolerability. Eleven patients reported nonsevere adverse effects that in 3 cases may have been related to the study preparation. Cod liver oil can be recommended for the treatment of rheumatoid arthritis.
