Pre-meal tomato (Lycopersicon esculentum) intake can have anti-obesity effects in young women?

Abstract

The effect of pre-meal tomato intake in the anthropometric indices and blood levels of triglycerides, cholesterol, glucose, and uric acid of a young women population (n ¼ 35, 19.6 ± 1.3 years) was evaluated. During 4 weeks, daily, participants ingested a raw ripe tomato ($90 g) before lunch. Their anthropometric and biochemical parameters were measured repeatedly during the follow-up time. At the end of the 4 weeks, significant reductions were observed on body weight (À1.09 ± 0.12 kg on average), % fat (À1.54 ± 0.52%), fasting blood glucose (À5.29 ± 0.80 mg/dl), triglycerides (À8.31 ± 1.34 mg/dl), cholesterol (À10.17 ± 1.21 mg/ dl), and uric acid (À0.16 ± 0.04 mg/dl) of the participants. The tomato pre-meal ingestion seemed to interfere positively in body weight, fat percentage, and blood levels of glucose, triglycerides, cholesterol, and uric acid of the young adult women that participated in this study.

Positive association of tomato consumption with serum urate: support for tomato consumption as an anecdotal trigger of gout flares

“…Lee et al [ 43 ] found an average increase of 46 μmolL −1 ( P < 0.05) in plasma urate levels in a small cohort of young Chinese men ( n = 10, 26 ± 1 years) 48 h after consumption of 150 g tomato sauce [ 43 ]. Conversely a recent study by Vinha et al [ 46 ] found an average drop of 10 μmolL −1 in plasma urate levels ( P < 0.05) in a cohort of young women ( n = 35, 19.6 ± 1.3 years) who ingested a ~90 g tomato before their midday meal for 30 consecutive days. Four additional intervention studies were unable to find any significant difference in serum or plasma urate levels after intervention [ 40 , 41 , 44 , 45 ].…”

“…To assess the causal influence of tomatoes on serum urate levels intervention studies need to be conducted. Small studies investigating the influence of tomatoes or tomato products on other biomarkers have been conducted, with several measuring urate levels before and after intervention took place (Table 3 ) [ 40 – 46 ]. Lee et al [ 43 ] found an average increase of 46 μmolL −1 ( P < 0.05) in plasma urate levels in a small cohort of young Chinese men ( n = 10, 26 ± 1 years) 48 h after consumption of 150 g tomato sauce [ 43 ].…”

“…Similarly Jacob et al [ 43 ] found no significant difference in the plasma urate levels of 12 individuals (23 ± 2 years) after consumption of 500 mL tomato juice per day for 2 weeks, however an increase in renal urate clearance (urate:creatinine ratio) was observed in these individuals ( P < 0.05). Only the study conducted by Vinha et al [ 46 ] used whole tomato fruit as the intervention product, more commonly tomato juice or sauce was used in these studies. This creates the possibility that other additives or the concentrated nature or the processing (eg production and loss of urate-influencing chemicals) of these products influence urate levels, such as sugars (2-3 % content) or added vitamin C (0-4 % content).…”

“…Generally, the demographics of the groups studied (Table 3 ) are different (younger) to the group in which we associated tomato consumption with serum urate levels (Additional file 4 : Table S3). In the case of Vinha et al [ 46 ] their conclusion that the changes in biochemical and anthropometric parameters may be due to a decrease in postprandial hunger suggests the decrease in plasma urate levels observed could be due to a decrease in consumption of other serum urate-raising foods between meals rather than solely the function of tomato consumption itself. The influence of other serum urate-raising foods was accounted for in our analysis.…”

Analisis Kadar Asam Urat Wanita Dewasa Usia 40-60 Tahun Setelah Konsumsi Jus Tomat-Jeruk Nipis

“…Penelitian mengenai konsumsi tomat 90 gr sebelum makan siang pada mahasiswa di CESPU, Portugal dapat menurunkan kadar asam urat (−0.16 ± 0.04 mg/dl) selama 4 minggu. 5 Penelitian lain menyebutkan pemberian perasan jeruk nipis dengan dosis 0,65 ml/ 20 gr BB mencit terbukti efektif dapat menurunkan asam urat 0,433 mg/dl dalam waktu 7 hari. 6 Tomat dan jeruk nipis merupakan contoh buah yang menghasilkan sisa basa pada urin (Urine Alkaline).…”
