To eat protein or not to eat protien that's my question
Based on the study below, one should avoid high GI foods. We all know this.
According to this study one also must restrict protein,

I thought protein was essential for healthy hair, vegans that don't eat enough have hair loss.
But, I also heard that too much protein shortens the life span, increases bad POPs in the body. It is also connected to IGF-1.
How much (organic-grass fed animal, and/or plant-based) protein should I eat??????

RESULTS: Serum IGFBP-1 declined markedly after both meals, but the mean (+/-SEM) change at 4 h was significantly (P < 0.01) more prolonged after the low-GI meal (-55 +/- 20 ng/mL) than after the high-GI meal (-13 +/- 15 ng/mL). Conversely, the change in serum IGFBP-3 concentration at 4 h was significantly (P < 0.05) higher after the low-GI meal (251 +/- 102 ng/mL) than after the high-GI meal (-110 +/- 96 ng/mL); the same pattern was observed at 2 h. Changes in IGFBP-2, free IGF-1, and total IGF-1 responses were minimal and did not differ significantly from those during the 4-h fast.
CONCLUSION: Acute changes in IGFBP-3 after low-GI and high-GI foods may provide a biologic mechanism linking cell multiplication with greater consumption of high-GI carbohydrates.
According to this study one also must restrict protein,
Source: Long-term effects of calorie or protein restriction on serum IGF-1 and IGFBP-3 concentration in humans.long-term severe CR does not reduce serum IGF-1 concentration and IGF-1 : IGFBP-3 ratio in humans. In addition, our data provide evidence that protein intake is a key determinant of circulating IGF-1 levels in humans, and suggest that reduced protein intake may become an important component of anticancer and anti-aging dietary interventions
