Can eating too many nuts be bad for health?

[andyjohnsonman]

I started a Keto diet last week and due to the lack of carbs i find it hard to fill up and not be hungry. To counter this I bought a 2.5kg bag of cashew nuts that I eat whenever I feel hungry, however today I noticed this is causing diarrhea so was wondering if eating too many nuts can be bad or if my body is just adjusting to this new diet?

Yea thats a good point. Im eating loads of cashew nuts! They are un roasted so i'm wondering if its down to that as apparently truly raw cashews have toxins int them from poison ivy but that is doubtful because even though the nuts say un roasted apparently most go through roasting before taking the shell off and the ones that are roasted have a second session of roasting.

Careful with nuts. I don´t think the human body is prepared to eat nuts in large quantities as a regular thing.

I used to do Keto too and I would eat a shit ton of nuts in the morning. I ended up having the worst stomach aches and pain and nausea ever. Needless to say now I can´t basically eat a single nut. Since just seeing them makes me sick.

PD: Just read you are talking about cashews. I haven´t find that difficult to digest those. Also pistacchios are probably the most easy on the stomach too. My main issue was with walnuts. Those are the ones which I can´t eat now

be careful with cashew, not more than 20 cashew for a week, this is MY advice, I am eating it for 4 years in a row almost everyday, and my kidneys are going mad sometimes. This is pure protein, do not mix it with eggs and meat!

My nutritionist said that the daily value of nuts is about 5-10 grams.

30-80 g is a lot. exactly 5-15 g
so my nutritionist said

They have lots of copper. Zinc picolinate or high zinc foods can solve it. Nuts have a lot of polyunsaturated fat which is very likely anti-thyroid if eaten in amounts way out of proportion to saturated fat. They also have a lopsided amino acid profile and that can have psychoactive effects if they're eaten without other protein sources to compensate.

I would not recommend keto unless you have health problems -- mainly insulin resistance. Use keto (with high protein and resistance training) to reduce visceral fat, for no more than 6 months, in order to get your insulin response healthier and then you won't get high BG after high carbs meals. High carb is fine; low carb is fine... NO carb and very low carb (<125g/d) is not optimal for health, and may actually not even be safe. Especially in the long-term.

Phytates, lectins, omega-6, pesticides (organic or inorganic ones). Really no reason to eat nuts at all.

personally love nuts.

Keto seems really dangerous to me. Not sure why anyone would think its a good idea.

If you take 100 people, put them in lab, feed them high saturated  fat, low-fibre diet for 3 months you will see a rapid acceleration of cardiovascular disease marker and markers of systemic inflammation. Naturally, we don't have such studies because who would survive locked in lab...

This is probably true, but particularly provided they're in a weekly/etc net calorie surplus. If one doesn't resistance train (which changes protein needs which would need to be accounted for), one could argue they already don't care about their health (if they only knew, anyway) because that's probably the most effective way to extend one's life, so that would have to be accounted for. Saturated fat is perfectly healthy, and it can and maybe even should be consumed in amounts that vastly exceed PUFA intake... However, this is only optimal as part of a diet already quite low in total fat. You only "need" around 1g of n-3 and 6g of n-6 a day (though total fat under 20g / day is associated with increased injury rate), and that's just to prevent the state of PUFA deficiency, which is characterized by increased metabolic rate and reduced inflammation via increased T3 conversion and increased production of the anti-inflammatory mead acid from saturated fat. The increased metabolic rate in deficiency means one has to compensate with more food if they are to stay at the same weight... And to meet their increased micronutrient needs -- though that/this last sentence is not conclusive by any means, just my intuition along with a holistic interpretation of the data as it stands.

High saturated fat and low fiber are mainly associated with health problems in the extremes, and in the presence of health problems; insulin resistance, and often excess fructose consumption... and lack of weight training, and already-excessive visceral fat. If one eats a balanced diet of whole foods, with adequate protein, and weight training, and with low body fat content (if there is excess body fat, getting rid of that asap with the underlined text + a calorie deficit via eating highly satiating foods such as potatoes; eggs; Greek yogurt), then there really just isn't a whole lot more one can do to increase their chances of having a life expectancy several standard deviations above the mean -- the fiber content of their diet will be largely irrelevant.

@Michael569 I think "the answer" for the cohort you're referring to is probably just resistance training + protein sparing modified fast if they're overweight, to get their insulin sensitivity to skyrocket and then they'd be like 100x more resilient to any harmful dietary habits. But yeah, if they aren't going to do that it would be helpful for them to know saturated fat is certainly harmful in excess, as is any kind of fat -- one of many reasons I have for never recommending keto unless it's specifically for the goal of losing fat, in a calorie deficit, for less than 6 months and never again. And even then, I'd say anyone who isn't weight training (or if they're unable, doing something that resembles it -- any load bearing activity involving at least one activity of each 1. pushing, 2. pulling, and 3. leg-dominant movement) getting adequate protein (easy, but making sure it is done), and eating whole foods (and losing fat if they need to)... is likely missing out on a longer life. And if they're doing keto without also doing those, they're wasting their time.

And of course if one is so unhealthy as to be ravaged by cholesterol, fiber can help them.
